Marine Warranty Surveying and Marine Salvage

  • Overview

The Marine Warranty Surveying and Marine Salvage Special Interest Group (MWS SIG) promotes the effective implementation of Marine Warranty Surveying (MWS) and Marine Salvage operations. 

MWS is a risk management service provided to the offshore and maritime industries, involving independent third-party verification of high-value or high-risk marine operations. Its primary objective is to ensure compliance with industry standards, safety regulations, and best practices to minimise risks. 

Similarly, marine salvage involves the recovery of vessels, cargo, or other property from peril at sea. This may include refloating stranded vessels, removing wrecks, and salvaging valuable cargo. Salvage operations are crucial in preventing environmental disasters, minimising financial losses, and maintaining navigational safety. 

If you are interested in joining the group, log in to My IMarEST and select the group from the list.
