Our expert divers and technicians perform photographic hull inspections and surveys, backed by full CCTV and DVD footage. Our technical reports provide a detailed assessment of general hull condition, the state of paint coating, catholic protection, and any damage to steel surfaces and appendages. SEALION inspections are an invaluable aide for classification society in class surveys, sale and purchase, and planning for dry dock work.
Our expert divers use approved and patented hull surface cleaning machines that are globally recognised as the most effective means to recuperate vessels performance and service speed. Advance cleaning techniques and equipment ensure that no damage is caused to the most delicate of anti-fouling systems, such as silicone and other soft-coated paints.
Regular polishing reduces propeller surface roughness up to a Rubert’s comparator’s scale A/B, to ensure maximum thrust, diminishing drag and optimum propeller hydro-efficiency. Our teams can also repair propeller damage and surface erosion, with the added benefit of reducing stress on the propeller shaft and your vessel’s engines.
We use the latest technology and the most advanced techniques to meet any underwater engineering challenge. SEALION is the recognised leader in underwater welding of hull cracks, patching or replacing steel plate sections (with cofferdam when required), securing cracks with Cox’s underwater bolts, replacing wasted zinc anodes, sealing stern gland and blanking sea water inlets to allow for internal repairs, and cropping and balancing damaged propellers.
