A guide to marine approval including explanations, applications and a choice of products certified for marine use.
All voyage and safety critical equipment on a ship must be certified by the same marine approval body that audited and registered the whole ship.
A Marine Approved device is one that has been tested and certified by a recognised body such as LR (Lloyd’s Register), GL (Germanischer Lloyd), DNV (Det Norske Veritas), ABS (American Bureau of Shipping) and CCS (China Classification Society) for use on a ship.
The marine approval process involves an initial and continuous periodic product assessment to inspect random production samples, ensure adequate production and inspection processes, procedures, documentation and quality control, and review the current product design and any future design iterations for compliance with the type approval.
