Delmar SubSea ConneCtorUS Patent #6,158,093
Delmar Subsea Connector The patented Delmar Subsea Connector (DSC) saves operators valuable time and money through the use of a simple and reliable male-female locking mechanism. This design completely eliminates the need to unseat the anchor before implementing mooring component repairs or replacements, significantly cutting down on maintenance time.
Using a single remotely operated vehicle (ROV), the DSC can be secured into place easily and efficiently. Anchors can be preset and the mooring line attachment completed later at the convenience of the operator.
For permanent facilities, site-specific analysis and mooring component minimum breaking loads (MBLs) are used to dictate the fully customizable size of the DSCs required, allowing for a perfect fit in both
reliability and safety considerations.
Other applications for the Delmar Subsea Connector include increased flexibility for deepwater production
vessels (DPs), increased security for offshore wind farms and other offshore vessels, installation and recovery of pipeline initiation piles, and retrieval of subsea packages. Delmar’s rental fleet of DSCs are also extensively used for rapid re-
entry into existing MODU mooring patterns for workover operations.
Pile Recovery Pre-Staged Connection In-line Mooring Connection
Custom Design• Permanent and MODU mooring targeted for individual project needs including DSC size,
MBLs, and other site-specific concerns
• Accommodates all combinations of chain, wire, and synthetic mooring lines
• Fits all types of anchor and subsea foundations including suction pile, driven pile, OMNI-Max®, VLA, conventional, and more
• Classification society-approved disconnectable device for use in both temporary and permanent mooring systems
ROV Compatible• Easily operated by any typical work-class ROV system
• No specific tools needed for ROV package to install DSCs
Quality Construction• Made of high-strength cast steel (modified R3 or R4 materials)
• ABS Product Design Assessment approval and DNV GL type approval
• Excellent fatigue life properties—DSC exceeds the life of chains with equivalent MBL
• Corrosion protection comes standard with a three-part epoxy marine coating; additional special order coating available
Safe, Secure, Reliable• Simplicity of design provides fail-safe performance and reduces operator error
• Locking device with both screw latch and T-bar latch mechanisms ensures a reliable connection during installation and slack-line conditions
