Delmar Subsea Connector

The Delmar Subsea Connector (DSC) allows for the separate installation or recovery of the anchor and mooring leg, which reduces costs and risks for both the installer and the operator. With our ability to disconnect at the anchor to periodically inspect mooring leg components, we can improve inspection, maintenance, repair, and mooring integrity management. This increased insight and enhanced analysis helps lower costs and allows for the use of shorter-life materials.
