Underwater services
Full range of diving operations.
Our Principals’ network consists of commercial diving companies operating in the maritime industry with highly skilled technicians, offering a full spectrum husbandry of inshore commercial diving in ships’ maintenance and repair works.
In-water surveys
IACS approved
Class surveys in lieu of dry-docking, with video and a written report for owner and class. Rudder pintle clearance and tail shaft wear down measurments.
Hull cleaning
Marine coatings approved
Cleaning methods approved by the coating makers, ensuring that the antifouling stays intact and the warranty holds.
Propeller polishing
Fuel saving between dockings
Blade polishing that restores the surface finish and takes back the fuel lost to roughness and fouling.
Hull and welding repairs
Wet welding and cofferdams
Underwater welding and cofferdam repairs to class standards, planned and witnessed as required.
Underwater ship repair
Seals · propellers · scrubbers
Stern-tube seal replacements, propeller repairs and underwater scrubber repairs without a dry dock.
Blanking of overboard pipes
Sea chests and O/B pipes
Blanks fitted so valve and pipe work can be done afloat, removed and checked on completion.
Accepted by class
In-water surveys recognised by IACS.
The diving companies we represent hold in-water survey approvals from the classification societies below, so a survey afloat can count where a docking survey would otherwise be due.
