Lloyd's Register Certified - What It Means for You
When you work with Wells Marine Diving Services, you’re working with a Lloyd’s Register approved service supplier. Approval is earned through an independent audit process and has to be renewed to stay current. Lloyd’s Register has been setting standards for the maritime sector since 1760, and its certification is recognised throughout the industry.
Wells Marine holds Lloyd’s Register approval for In-Water Surveys (IWS) on ships and Mobile Offshore Units – the category covering diver and ROV-based survey work on vessels and marine structures. This means our procedures, equipment and safety systems have been independently checked against the standard Lloyd’s Register sets for this type of work.
