Frequently asked questions

What types of survey vessel can be financed?

Finance is available for hydrographic survey vessels, seismic survey vessels, oceanographic research vessels, environmental monitoring vessels and ROV (remotely operated vehicle) support vessels. Lenders assess the vessel's MCA certification, the operator's contracted survey income, and the borrower's financial profile and trading history.

Who typically buys survey and research vessels?

The main buyers are environmental consultancies, offshore energy companies (oil and gas, offshore wind), marine geotechnical survey contractors, government agencies (UKHO, Environment Agency, CEFAS), scientific institutions (universities, research councils) and specialist survey contractors such as Fugro, CGG, TGS and Shearwater.

What are typical ticket sizes for survey vessel finance?

Survey vessel ticket sizes range from £500,000 for smaller inshore hydrographic vessels to over £10,000,000 for large offshore survey and seismic vessels. Most standard asset finance lenders focus on the £500,000–£3,000,000 range. Larger transactions may require specialist maritime project finance.

How does contracting income affect survey vessel finance?

Contracted survey income - particularly multi-year contracts with creditworthy clients such as offshore energy majors or government agencies - significantly strengthens a survey vessel finance application. Lenders view contracted revenue as near-certain debt service coverage, which can improve available LTV and reduce pricing. Our team advises on presenting contract documentation most effectively to lenders.
