Marine Contractor Insurance

Marine contractors, harbour contractors, coastal engineering businesses and marine civil engineering companies can face complex insurance considerations because their work often involves marine structures, waterfront infrastructure, floating plant, dredging, piling, environmental controls, tidal working and construction over or alongside water.

Quote Monkey may be able to introduce suitable enquiries to a specialist broker experienced in arranging insurance for marine contractors, harbour contractors, port contractors, dredging companies, coastal engineering businesses, marine piling contractors and waterfront infrastructure specialists.

Marine Contractor Insurance For Harbour, Coastal And Marine Infrastructure Projects

Marine Contractor Insurance

Marine Contractor Insurance is intended to consider the specialist risks faced by businesses working on harbours, ports, marinas, docks, jetties, piers, quay walls, wharves, slipways, sea defences, flood defences, rivers, canals, reservoirs, lakes, inland waterways, estuaries, coastal waters and waterfront regeneration projects. Marine contracting can involve ordinary construction exposures, but with added risks from tides, currents, live navigation, floating plant, environmental controls, protected habitats and work over or below water.

Insurance requirements can vary depending on whether the contractor undertakes marine civil engineering, dredging, marine piling, quay wall construction, harbour maintenance, sea wall repairs, breakwater works, revetments, groynes, cofferdams, land reclamation, flood gates, tidal barriers, marina development or emergency marine repairs. A specialist broker will usually need to understand work methods, contract values, client types, plant values, environmental responsibilities, subcontractor use and any design or survey responsibility.

Marine Civil Engineering Contractors

Marine civil engineering contractors may deliver foundations, retaining structures, sheet piling, concrete works, scour protection, quay walls, lock chambers, sluices, weirs, lock gates, dolphins, fender systems, slipways, pontoons, moorings, jetties, river walls, canal infrastructure, wave attenuation structures and coastal resilience projects. These works can be technically demanding because they may involve tidal windows, water pressure, silt, sediment, seabed preparation, restricted access and weather delays.

Insurers may ask whether projects are inland, coastal, estuarine, tidal, harbour-based, canal-based, reservoir-based, lake-based, flood plain based or offshore. They may also ask whether the contractor works from land, barges, crane barges, spud barges, hopper barges, jack-up barges, pontoons, floating pontoons, workboats, tug boats, crew transfer vessels or temporary marine access platforms.

Harbour And Port Construction

Harbour and port construction projects may include berth upgrades, quay improvements, dock repairs, dry dock works, wet dock works, container terminal infrastructure, ferry terminal works, oil terminal repairs, LNG terminal support works, fendering, mooring infrastructure, drainage, surfacing, access roads, sea defences, utility routes and operational waterfront repairs. Contractors may work around port authorities, harbour authorities, shipping operators, cargo handlers, commercial ports, defence estates, naval bases, shipyards and public visitors.

Insurance considerations can include damage to operational port assets, injury to third parties, disruption to commercial activities, plant movements, vessel movements, live navigation, environmental pollution, fuel spills, hydraulic oil leaks and access restrictions. A specialist broker may ask whether the harbour, port, terminal or dock remains operational during works and how navigation, traffic and public safety are controlled.

Dock, Quay Wall And Wharf Contractors

Dock, quay wall and wharf contractors may carry out repairs, strengthening, replacement, piling, concrete works, tie rod installation, fendering, coping repairs, scour protection and structural maintenance. These projects can involve older waterfront structures, unknown defects, water pressure, lifting operations, temporary works, confined spaces and restricted working platforms.

Where quay walls, wharves or dock structures support commercial operations, shipyards, ferry terminals or public access, the consequences of defective works can be significant. Insurers may ask whether structural design is provided by a consulting engineer, by the contractor, by a subcontractor or by the client, and whether Professional Indemnity Insurance should be considered.

Marina Construction Projects

Marina construction contractors may install pontoons, floating pontoons, walkways, access ramps, piles, mooring systems, service pedestals, shore connections, utilities, car parks, drainage and waterside infrastructure. Marina projects may involve private marina operators, boat owners, berth holders, leisure visitors, public walkways, waterfront tenants and live marina operations.

Insurance requirements may depend on whether the contractor works with floating structures, electrical services near water, pedestrian access, temporary barriers, dredging, piling, utility routes or environmental permissions. The contractor should explain whether the marina remains open during works and how public access, boat access, water quality monitoring and marine ecology are managed.

Marine Piling Contractors

Marine piling contractors may install steel piles, timber piles, concrete piles, sheet piles, retaining structures and foundations for jetties, piers, pontoons, quay walls, bridges, flood defences, dolphins, fender systems, tidal barriers and waterfront structures. Marine piling may involve vibro piling, driven piling, bored piling, drilling, hammering, lifting, barges, pontoons, jack-up platforms and challenging ground conditions.

Insurers may ask about piling methods, temporary works, plant ownership, floating cranes, marine cranes, long-reach excavators, amphibious excavators, vibration monitoring, noise controls, environmental controls and design responsibility. Piling near existing structures, underwater services, protected habitats, fish spawning areas or contaminated sediments may need particularly detailed risk presentation.

Dredging And Seabed Preparation

Dredging contractors may remove silt, sediment, gravel, debris or contaminated material from harbours, marinas, canals, rivers, reservoirs, docks, outfalls, navigation channels and seabed areas. Dredging may be undertaken for maintenance, construction, flood resilience, navigation, marina development, land reclamation, reclamation works, seabed preparation or environmental improvement.

Insurance considerations may include cutter suction dredgers, grab dredgers, hopper barges, workboats, disposal of dredged material, contaminated water, turbidity, silt disturbance, underwater services and protected habitats. Contractors should explain whether dredged material is tested, transported, treated, reused or disposed of under permit.

Flood Defence And Coastal Resilience Contractors

Flood defence contractors may work on flood walls, tidal barriers, flood gates, river walls, embankments, pumping station civils, drainage improvements, culverts, outfalls, coastal defences and sea level rise adaptation projects. Coastal resilience may involve sea walls, rock armour, breakwaters, revetments, groynes, wave attenuation structures, dune protection and erosion control.

Insurance discussions may include contract works, public liability, employers liability, environmental liability, pollution liability, plant, temporary works and professional indemnity. Projects that protect homes, roads, utilities, commercial waterfronts or public assets can create high consequence exposure if works fail, are delayed or create environmental damage.

River, Canal, Lake And Reservoir Engineering

River, canal, lake and reservoir engineering contractors may work on retaining walls, locks, weirs, sluices, lock gates, towpaths, embankments, bank stabilisation, moorings, culverts, bridges, dredging, erosion protection, reservoirs, water control assets and navigation structures. Clients may include the Canal & River Trust, local authorities, water companies, reservoir owners, private landowners and public infrastructure bodies.

These projects can involve boat users, walkers, cyclists, heritage assets, controlled water levels, public footpaths, flood plains, inland waterways and environmental sensitivities. Insurers may ask how the contractor manages temporary closures, live navigation, water level changes, pollution prevention, silt curtains, water quality monitoring and public safety around the works.

Coastal Engineering And Marine Construction

Marine Construction Methods, Equipment And Specialist Waterfront Operations

Cofferdams And Dewatering

Cofferdams and dewatering works may be used to create dry working areas for foundations, retaining walls, bridge works, outfalls, flood defences, lock repairs, quay wall repairs and underwater structure works. Temporary water exclusion systems can be critical to project safety and programme delivery.

Insurers may ask whether cofferdams and dewatering arrangements are designed in-house, by consulting engineers, by specialist subcontractors or by the client. Failure of temporary marine works can lead to flooding, pollution, plant damage, injury, damage to contract works and delay.

Sheet Piling, Rock Armour And Scour Protection

Sheet piling, rock armour installation and scour protection may be used for quay walls, river banks, bridge supports, sea walls, revetments, flood defences, marinas and waterfront retaining structures. These activities may involve heavy materials, lifting operations, vibration, unstable ground and work close to water.

A specialist broker may ask about plant used, lifting methods, vibration monitoring, materials handling, access constraints and any design responsibility. Scour protection and rock armour works may also affect water quality, habitats, fisheries and sediment movement.

Reclamation Works And Land Reclamation

Reclamation works and land reclamation projects may involve infilling, ground improvement, seawalls, retaining structures, drainage, dredged material management, geotextiles, seabed preparation and new waterfront development platforms. These projects can be large, technical and heavily regulated.

Insurance considerations may include environmental permits, marine licences, sediment testing, pollution liability, plant values, contract works, ground conditions and long-term stability. Contractors should explain whether they provide design, ground improvement advice or practical delivery only.

Underwater Concrete Placement

Underwater concrete placement may be required for foundations, scour repairs, bridge works, marine structures, quay walls, outfalls, culverts, reservoirs and repairs below water level. The work can involve specialist materials, pumps, divers, tremie methods, quality control and environmental precautions.

Insurers may ask about method statements, testing, water quality controls, pollution prevention and whether commercial diving support is used. Underwater concrete work may create both contract works exposure and environmental exposure if materials escape into the water.

Marine Surveying And Inspections

Marine surveying may include hydrographic surveys, bathymetric surveys, marine geotechnical surveys, sonar surveys, GPS positioning, ROV inspections, diving inspections and structural inspections. These surveys can support dredging, piling, quay repairs, bridge works, flood defences, seabed preparation and marine infrastructure maintenance.

Where a marine contractor provides survey reports, condition assessments, inspection findings or technical recommendations, Professional Indemnity Insurance may need to be discussed. If surveys are subcontracted, the contractor should explain how responsibilities and insurance are managed.

Commercial Diving And ROV Support

Some marine projects may involve commercial diving support, ROV inspections, underwater repairs, pile inspections, scour protection, submerged structures, debris removal or underwater concrete works. Diving and ROV support can provide essential access to areas that cannot be inspected or repaired from above water.

Insurers may ask whether the contractor undertakes diving directly, appoints specialist diving subcontractors or only coordinates projects where underwater support is required. Evidence of subcontractor insurance, competence, RAMS and safety procedures may be important.

Floating Plant And Marine Equipment

Marine contractors may use crane barges, jack-up barges, spud barges, hopper barges, tug boats, workboats, crew transfer vessels, pontoons, floating pontoons, floating cranes, marine cranes, amphibious excavators, floating excavators, long-reach excavators, cutter suction dredgers, grab dredgers, pumps, generators and piling rigs. These assets can be owned, hired in or supplied by specialist subcontractors.

A specialist broker may ask about plant values, hire terms, mooring arrangements, inspection records, operator competence, maintenance procedures, weather limitations and recovery plans. Floating plant can create different insurance questions from standard construction plant because sinking, grounding, collision, storm damage and pollution exposure may need to be considered.

Working In Marine Environments

Marine contractors may work in rivers, estuaries, harbours, ports, marinas, reservoirs, lakes, inland waterways, canals, coastal waters, intertidal zones, offshore environments and flood plains. Each environment can create different hazards, including tidal movements, strong currents, waves, soft ground, restricted access, live navigation, weather delays and remote locations.

Insurance requirements may depend on whether works are near the public, near vessels, near utilities, near protected habitats or inside operational commercial sites. A broad marine contractor should provide a clear work split so insurers understand the environments and activities involved.

Confined Spaces And Restricted Access

Marine contractors may encounter confined spaces in culverts, outfalls, sluices, lock chambers, chambers, pump stations, tanks, cofferdams, ducts and waterfront structures. Restricted access can also apply to pontoons, barges, tidal platforms, narrow towpaths, dock edges and below-deck work areas.

Insurance discussions may include confined space training, permits, atmospheric testing, rescue procedures, supervision, communications and emergency access. These risks should be explained separately from general construction activity because the consequences can be severe.

Live Navigation And Vessel Movements

Marine works may take place around live navigation, commercial vessels, leisure craft, ferries, workboats, tug boats, canal boats, harbour traffic and marina users. Contractors may need to coordinate exclusion zones, temporary closures, navigation notices, harbour authority requirements and vessel access.

Insurers may ask who controls navigation during works, how exclusion zones are marked, whether workboats are used and how vessel impact risks are managed. Live navigation can affect public liability, marine equipment risk, contract works and business interruption exposure.

Need Insurance For A Marine Contracting Business?

Marine contractors, harbour construction companies, dredging businesses, marine piling specialists and coastal engineering contractors often undertake complex work involving plant, contract works, environmental liability, pollution risks, floating equipment and work over water. Quote Monkey may be able to introduce suitable enquiries to a specialist broker experienced in arranging insurance for marine contractors and related businesses.

Marine Clients, Public Sector Contracts And Environmental Compliance

Port Authorities And Harbour Authorities

Port authorities and harbour authorities may appoint marine contractors for quay repairs, harbour walls, dock maintenance, fendering, dredging, slipways, navigation structures, moorings, access routes and flood resilience. These clients may have duties to commercial operators, leisure users, public visitors and vessel traffic.

Insurance requirements may be shaped by contract conditions, public liability exposure, plant movements, commercial interruption risks, live navigation, marine licences and environmental controls. Contractors should explain how works are separated from live operations and how harbour users are protected.

Local Authorities, Environment Agency And Canal & River Trust

Local authorities, the Environment Agency and the Canal & River Trust may appoint contractors for flood defences, sea walls, towpaths, locks, embankments, bridge works, dredging, erosion protection, river structures, culverts and public realm waterfront projects. These contracts can involve public access, environmental regulation and formal procurement requirements.

A broker may ask about framework agreements, public sector contract conditions, RAMS, CDM responsibilities, environmental permits, marine ecology controls and previous experience. Public sector marine works often require a clear explanation of insurance arrangements and risk controls.

National Highways, Network Rail And Utility Providers

National Highways, Network Rail, water companies, electricity providers, telecoms operators, drainage undertakers and utility providers may require marine contractors for water crossings, culverts, outfalls, bridge protection, river works, coastal assets, utility diversions, intake structures and service route protection. These projects can connect marine construction with transport and utility infrastructure.

Insurance considerations may include damage to utilities, service interruption, pollution, flooding, confined spaces, excavation, underwater services and work near critical public infrastructure. Where the contractor provides technical advice or inspection reports, professional indemnity exposure should be discussed.

Renewable Energy Developers And Offshore Support

Renewable energy developers may appoint marine contractors for coastal access, cable landfalls, outfalls, marine civils, scour protection, temporary works, floating plant support, quay upgrades and waterfront infrastructure connected with wind, tidal, solar, battery or grid projects. Some contractors may also support offshore environments or coastal energy infrastructure.

Insurers may ask about offshore exposure, crew transfer vessels, workboats, marine plant, lifting operations, weather windows, environmental permits and contract values. Renewable energy projects can combine marine construction, utilities, civil engineering and environmental obligations.

Private Marina Operators And Commercial Waterfronts

Private marina operators, commercial ports, waterfront developers, leisure operators, shipyards, oil terminals, LNG terminals, container terminals and commercial shipyards may require specialist marine works. These projects can involve active businesses, tenants, visitors, vessels, valuable property and operational continuity.

A specialist broker may ask whether the site remains open during works, how public access is controlled, how vessels are protected and whether work could affect commercial operations. The contractor's contractual responsibilities and client requirements should be clearly presented.

Defence Estates And Sensitive Waterfront Sites

Defence estates, naval bases, secure ports, restricted waterfront facilities and sensitive infrastructure sites may require marine contractors for docks, piers, access structures, flood defences, quay walls, utility crossings and maintenance. These projects may have strict access, security and confidentiality requirements.

Insurance discussions may consider site security, employee vetting, vehicle access, plant movement, contract conditions and specialist operational rules. Sensitive sites may also require robust documentation and evidence of suitable insurance before mobilisation.

Marine Licences And MMO Requirements

Marine licences and Marine Management Organisation requirements may be relevant where works affect tidal waters, seabed areas, dredging, disposal, coastal structures, piling, sea defences or marine habitats. Contractors may also need to work under environmental permits, planning conditions or client-specific environmental controls.

Insurers may ask whether the contractor obtains permits, follows permits held by the client or works under instructions from a principal contractor. Marine licences and environmental approvals can affect methods, timing, monitoring, waste handling and liability exposure.

Environmental Impact Assessments And Marine Ecology

Environmental Impact Assessments, marine ecology surveys, protected habitat assessments, fish spawning seasons, biodiversity controls, nesting restrictions and water quality monitoring may all influence marine construction methods. Works may need to avoid or reduce harm to protected habitats, shellfish waters, fisheries, birds, mammals, wetlands and sensitive watercourses.

Insurance discussions may include environmental liability, pollution liability, professional advice, subcontracted ecological services and compliance with permit conditions. Contractors should explain whether environmental advice is provided by them, by a consultant or by the client.

Pollution Prevention And Spill Response

Pollution prevention can be a major topic for marine contractors because fuel spills, hydraulic oil leaks, contaminated water, concrete washout, dredged sediment, dirty run-off and disturbed silt can quickly affect water quality. Marine pollution incidents may involve regulators, clean-up costs, third-party claims and reputational damage.

A specialist broker may ask about spill kits, fuel storage, plant maintenance, hydraulic hose inspections, silt curtains, containment systems, emergency response plans and specialist clean-up contractors. Pollution Liability Insurance may need to be considered separately from general liability arrangements.

RAMS, CDM And Marine Health And Safety

Marine contractors may need detailed RAMS covering working over water, tidal working, confined spaces, lifting operations, plant movements, temporary works, public access, pollution response, live navigation and emergency rescue. CDM responsibilities may also be relevant where the contractor acts as principal contractor or controls part of the site.

Insurers may ask whether risk assessments and method statements are produced in-house, reviewed by clients, updated as conditions change and communicated to employees and subcontractors. Strong documentation can help demonstrate that marine health and safety is actively managed.

Storm Damage, Weather Delays And Remote Locations

Marine works can be affected by storms, high winds, waves, heavy rain, tidal surges, strong currents, flooding, heat, cold and remote access. Weather can damage temporary works, delay projects, affect plant stability and make work over water more hazardous.

Insurance discussions may consider weather monitoring, suspension procedures, plant recovery, temporary works protection, emergency plans and contract conditions around delay. Remote locations may also require additional attention to rescue planning, communications and logistics.

Additional Insurance Considerations For Marine Contractors

Public Liability Insurance

Public Liability Insurance can be important for marine contractors because claims may involve injury to third parties, damage to vessels, damage to waterfront property, harbour assets, port infrastructure, navigation structures, utilities, public walkways or neighbouring premises. Claims may also arise from falling objects, temporary access, plant movements, work over water, pollution incidents or damage caused during marine construction activity.

The exposure can vary depending on whether the contractor works in harbours, ports, marinas, public promenades, rivers, canals, reservoirs, lakes, coastal paths, industrial waterfronts or operational docks. A specialist broker may ask how the contractor controls site boundaries, public access, live navigation and the interface with other users.

Employers Liability Insurance

Employers' Liability Insurance may be required where a marine contractor employs operatives, supervisors, engineers, plant operators, boat crews, drivers, site managers, project managers, office staff, apprentices, temporary workers or specialist marine personnel. Employees may face risks from working over water, lifting operations, confined spaces, floating plant, tidal conditions, heavy materials, edge hazards and unstable structures.

Insurers may ask about training, life jackets, rescue procedures, confined space procedures, PPE, working at height, working over water, working below water, supervision, accident history and health and safety systems. Tidal working, strong currents and rescue planning are often important details.

Contractors All Risks And Contract Works

Contractors All Risks Insurance and Contract Works Insurance may be relevant where the contractor is responsible for works in progress, materials, temporary works, marine structures, equipment, plant, pontoons, piles, barriers, flood defences or waterfront construction before completion. Marine projects may be vulnerable to storm damage, tidal conditions, flooding, vessel impact, theft and accidental damage before handover.

The need for contract works insurance depends on contract values, responsibility for materials, handover terms and exposure to damage while works are incomplete. Contractors should explain the maximum value of any one project and whether materials or components are stored on site, afloat or at a depot.

Marine Plant, Hired In Plant And Own Plant

Marine contractors may use floating excavators, amphibious excavators, long-reach excavators, workboats, tug boats, crew transfer vessels, dredgers, cutter suction dredgers, grab dredgers, floating cranes, marine cranes, crane barges, spud barges, hopper barges, pontoons, jack-up platforms, pumps, generators, piling equipment and specialist tools. Marine Plant Insurance, Hired In Plant Insurance and Own Plant Insurance may need to be considered depending on ownership and hire arrangements.

A specialist broker may ask for plant values, hired-in plant terms, mooring arrangements, lifting procedures, operator competence, inspection records, maintenance procedures, recovery plans and whether equipment is used on land, afloat, over water or below water. Hired-in plant can create significant contractual responsibility to equipment owners.

Commercial Marine Equipment And Goods In Transit

Commercial Marine Equipment Insurance and Goods In Transit Insurance may be relevant where the contractor transports tools, pumps, piles, fenders, pontoons, diving support equipment, access systems, materials and specialist marine components. Transport may involve road vehicles, trailers, vessels, cranes, barges or specialist hauliers.

Insurers may ask how equipment is loaded, secured, protected from theft, protected from corrosion and moved between sites. Marine equipment can be high value and may be difficult to replace quickly if damaged, stolen or lost during transit.

Professional Indemnity Insurance

Professional Indemnity Insurance may be relevant where a marine contractor provides design, drawings, specifications, hydrographic surveys, bathymetric surveys, marine geotechnical surveys, sonar surveys, GPS positioning advice, structural inspections, condition reports, temporary works input, piling design, flood resilience advice, coastal engineering recommendations, environmental advice or project management services.

If the contractor works only to designs supplied by consulting engineers or clients, that should be made clear. If the business provides design and build services, repair recommendations, marine surveys or technical reports, insurers may need more detail about qualifications, checks and subcontracted professional input.

Environmental Liability Insurance

Environmental Liability Insurance can be particularly important for marine contractors because works may take place near rivers, canals, harbours, ports, beaches, reservoirs, lakes, wetlands, protected habitats, shellfish waters, fisheries, drainage systems and coastal environments. Environmental harm can arise from sediment movement, silt disturbance, contaminated water, material escape, damaged habitats or accidental discharge.

A specialist broker may ask about environmental management plans, ecology surveys, permits, silt curtains, protected species controls, spill response, waste disposal, watercourse protection and monitoring procedures. Marine ecology considerations can be central on coastal, river, canal and dredging projects.

Pollution Liability Insurance

Pollution Liability Insurance may be relevant where there is exposure to fuel spills, hydraulic oil leaks, concrete washout, contaminated silt, dredged material, chemical leakage, sewage contamination, turbidity, dirty water discharge or accidental release of materials into the water. Pollution incidents in marine environments can be expensive, visible and regulator-sensitive.

Insurers may ask how fuel is stored, how plant is maintained, how hydraulic hoses are inspected, how spills are contained and how contaminated water or sediment is managed. Contractors should also explain emergency response procedures and whether specialist environmental subcontractors are retained.

Cyber, Directors And Officers And Business Interruption

Cyber Insurance may be relevant where a marine contractor relies on tender portals, digital drawings, survey data, GPS records, project software, environmental reports, client records, employee data, accounts systems and contract documentation. A cyber incident could disrupt project planning, communications and access to important documents.

Directors And Officers Insurance and Business Interruption Insurance may also be considered for marine contractors with formal management structures, employees, public sector contracts, environmental responsibilities and significant contractual obligations. Disruption to specialist plant, marine equipment, depots or access to sites can affect the ability to deliver works.

Fleet, Commercial Vehicle, Property And Legal Expenses

Marine contractors may operate vans, pickups, tippers, lorries, trailers, plant transport vehicles, service vehicles and specialist access vehicles. Fleet Insurance and Commercial Vehicle Insurance may be relevant where vehicles transport employees, plant, tools, materials and equipment between depots, harbours, ports, marinas, canals, rivers and coastal sites.

Property Insurance, Legal Expenses Insurance and Personal Accident Insurance may also be relevant depending on the premises, depots, yards, employees, directors and contract structure. Site logistics can be more complex where access is tidal, restricted, remote, public-facing or within operational ports.

Insurance Considerations In One Programme

Marine contractors may need to discuss Public Liability Insurance, Employers' Liability Insurance, Contractors All Risks Insurance, Contract Works Insurance, Marine Plant Insurance, Hired In Plant Insurance, Own Plant Insurance, Commercial Marine Equipment Insurance, Fleet Insurance, Commercial Vehicle Insurance, Goods In Transit Insurance, Property Insurance, Professional Indemnity Insurance, Environmental Liability Insurance, Pollution Liability Insurance, Cyber Insurance, Directors And Officers Insurance, Legal Expenses Insurance, Personal Accident Insurance and Business Interruption Insurance.

The right combination depends on whether the contractor works on harbours, ports, docks, marinas, jetties, piers, quay walls, wharves, slipways, sea walls, breakwaters, revetments, groynes, flood defences, dredging, piling, rivers, canals, reservoirs, lakes, navigation structures, temporary marine works, cofferdams, public sector contracts, utility clients or emergency marine repairs.

Request A Specialist Broker Referral

A specialist broker will usually need detailed information before approaching suitable insurers. This may include turnover, work split, contract values, client types, work over water exposure, tidal working, floating plant, workboats, dredgers, marine cranes, long-reach excavators, employee numbers, subcontractor use, environmental controls, pollution prevention, RAMS, CDM responsibilities, claims history and any design responsibility.
