Subsea cable installation involves working in hazardous marine environments. Divers, offshore workers, and vessel crew face risks including decompression sickness, drowning, equipment failure, and workplace accidents. Proper safety protocols and comprehensive workers' compensation coverage are critical for protecting personnel and managing liability.

Regulatory and Compliance Risks

Subsea cable projects must comply with numerous international maritime regulations, environmental protection laws, and telecommunications standards. Failure to meet regulatory requirements can result in project delays, fines, and legal action. Different jurisdictions impose varying requirements, complicating multi-national projects.

Types of Insurance Coverage

Marine Cargo Insurance

Marine cargo insurance protects cables and equipment during transportation to the installation site. This coverage typically includes protection against loss or damage during loading, unloading, and transit by sea. Given the high value of subsea cables, comprehensive cargo coverage is essential. Policies should specify coverage for the full replacement value and include protection against theft, weather damage, and handling accidents.

Contractors' All Risks (CAR) Insurance

CAR insurance is fundamental for subsea cable installation projects. This comprehensive coverage protects against physical loss or damage to the project works, including cables, equipment, and temporary structures. CAR policies typically cover accidental damage from any cause, subject to specific exclusions. For subsea projects, CAR coverage should extend throughout the installation period and include coverage for testing and commissioning phases.

Marine Liability Insurance

Marine liability coverage protects against third-party claims arising from project activities. This includes liability for damage to other vessels, interference with fishing activities, environmental damage, and injury to third parties. Given the shared nature of maritime spaces, robust liability coverage is essential. Policies should provide adequate limits to cover potential catastrophic incidents.

Equipment and Machinery Insurance

Specialized cable-laying vessels and equipment require dedicated coverage. Equipment insurance protects against breakdown, mechanical failure, and accidental damage. For subsea projects, this coverage should include protection during transit, installation, and standby periods. Coverage should address the specific risks associated with marine operations, including corrosion and salt-water damage.

Professional Indemnity Insurance

Engineers, surveyors, and project managers involved in subsea cable installation should carry professional indemnity insurance. This coverage protects against claims arising from design errors, inadequate surveys, or professional negligence. Given the complexity of subsea projects, the potential for costly errors is significant, making professional indemnity coverage essential for consulting firms and engineering companies.

Environmental Liability Insurance

Environmental liability coverage protects against claims arising from pollution, marine ecosystem damage, or environmental contamination. Subsea cable installation can potentially impact marine habitats, and environmental regulations impose strict liability standards. This coverage is increasingly important as environmental protection requirements become more stringent.

Cyber Insurance

Modern subsea cable projects rely heavily on digital systems for positioning, monitoring, and control. Cyber insurance protects against losses resulting from cyber attacks, data breaches, or system failures affecting project operations. As projects become increasingly digitized, cyber coverage becomes more relevant.

Coverage Considerations and Exclusions

War and Terrorism Exclusions

Standard insurance policies typically exclude losses resulting from war, civil unrest, or terrorism. For projects in geopolitically sensitive regions, additional coverage may be necessary. War risk insurance is available but comes at premium rates and may require specific underwriting.

Delay and Consequential Loss

Standard policies often exclude losses resulting from project delays or business interruption. However, delay in startup (DIS) coverage can be obtained to protect against financial losses resulting from project postponement. This coverage is particularly valuable for subsea projects where weather delays are common.

Existing Damage and Pre-existing Conditions

Insurance policies typically exclude losses resulting from pre-existing damage or defects. Comprehensive pre-installation surveys and documentation are essential to establish the baseline condition of the project site and equipment.

Maintenance and Wear

Normal wear and tear, inadequate maintenance, and gradual deterioration are typically excluded from coverage. Proper maintenance protocols and regular inspections are necessary to maintain policy validity.

Claims Process and Best Practices

Documentation and Record-Keeping

Comprehensive documentation is essential for successful claims. Maintain detailed records of project activities, equipment inspections, weather conditions, and incident reports. Photographic and video evidence should be collected throughout the project. All communications with contractors, suppliers, and authorities should be documented.

Incident Reporting

Prompt reporting of incidents to your insurer is critical. Most policies require notification within specific timeframes. Detailed incident reports should include descriptions of what occurred, when it happened, who was involved, and preliminary damage assessments. Timely reporting demonstrates good faith and helps preserve coverage.

Mitigation Measures

Upon discovering a loss, take reasonable steps to minimize damage. This might include stopping operations, securing equipment, or implementing emergency repairs. Insurers expect policyholders to act reasonably to prevent further loss. Document all mitigation efforts for the claims file.
