4S Maritime are independent marine surveyors.

We have experience in most "traditional" marine surveys; lashing and securing, loadout, on-hire and off-hire surveys, hull / cargo damage and towing.


We also perform Hull and Machinery, ISM audits pre-purchase surveys and P&I inspections.

Consideration for, and management of, risk and costs are always our priorities!

Ship Certification & Classification

IMCA eCMID & eMISW inspection formats are common standards for inspecting and auditing vessels in the offshore industry bearing in mind their special nature of work and equipment, be it jack-up installation vessels, PSV's, crew transport, offshore service, walk-to-work or diving vessels.

Inspectors are authorized by IMCA / IIMS through an accreditation process and maintain their status through continuous professional development.

We carry out IMCA inspections all over Northern Europe and offer fixed price for Danish ports.

Please contact us to book your inspection.
