In brief

Insurance for hydrographic and geophysical survey equipment can be considered around declared instruments and their planned use. Cover is not automatic for towing, deployment, free-in-water operation, testing or work on equipment; every stage depends on disclosure, underwriting, market appetite and policy wording.

Who this route is for

  • Hydrographic and bathymetric survey companies.
  • Marine geophysical and site-investigation contractors.
  • Cable-route, seabed-characterisation and offshore-development survey teams.
  • Specialists providing survey spreads with vessel or positioning support.

Equipment to identify

  • Multibeam and single-beam echo sounders, side-scan sonar and sub-bottom profilers.
  • GNSS, inertial navigation, motion-reference and positioning systems.
  • Magnetometers, hydrophones, recorders, tow bodies and winches.
  • Computers, acquisition systems, transducers and temporary vessel installations.

Information to prepare

  • Survey spread, individual and total values, ownership and maximum concentration at one site.
  • Mounting, towing, overboarding, launch, recovery and vessel-integration method.
  • Water depth, seabed conditions, weather criteria, project area and navigation limits.
  • Crew competence, maintenance, calibration, spares, contracts and previous losses.

Questions to check in the wording

  • Which items are declared, at what values, and who owns them at each stage?
  • Does the proposed wording address storage, transit, loading, testing, deployment, operation and recovery where required?
  • How do exclusions, conditions, deductibles and territorial or depth restrictions affect the planned work?
  • Are liability, pollution, professional indemnity, cyber or interruption exposures separate from physical equipment damage?

How this route differs

This page targets seabed mapping, positioning and subsurface survey spreads. Environmental sampling and ecological monitoring use a different route, while robotic vehicles belong on the ROV/AUV/USV operators page.

Hydrographic And Geophysical Survey Equipment Insurance FAQs

Can towed survey equipment be insured?

It may be considered, but the equipment, tow arrangement, operating parameters, water depth, location and recovery controls must be disclosed and accepted in the wording.

Does vessel insurance cover a temporary survey spread?

Do not assume it does. The vessel, specialist equipment and contractual responsibility may sit under different policies or interests.

What should a hydrographic contractor prepare?

Provide an itemised spread, values, survey method, vessel details, project locations, competence, maintenance, contracts and loss history.
