Delmar's Releasable Mooring System

Featuring Next-Generation Rig Anchor Release Technology

Join the Releasable Revolution!


Delmar System’s Releasable Mooring System is perfectly suited for the moored and DP/moored semi-submersible rig fleet and offers maximum efficiency, flexibility, and safety for operators and rig owners.

Developed with the experience of thousands of successful rig moves, our Releasable Mooring System greatly reduces risks and provides a path to regulatory approval for eight-line MODU systems in regions that have historically required more time-consuming and costly mooring spreads.

Features of the Releasable Mooring System

  • Maximized rig move efficiency
  • Cost savings on rig moves with quick disconnect times and weather delay avoidance
  • Allows rigs to quickly evade storms, ice floes, or well emergencies
  • AHV weather downtime eliminated
  • Reduced HSE exposure time for on-deck personnel
  • Minimized AHV time for rig move

Experience the RAR Plus™ Difference

The RAR Plus builds on a 35-plus year history of proven acoustic release technology and represents the latest and greatest development in next-generation Rig Anchor Release (RAR) technologies.

  • DNV- and ABS-certified mooring component
  • Minimum Break Load (MBL) of 900 tonnes for greater robustness
  • Release load rating of 360+ tonnes allowing for disconnection of higher line tensions
  • Surface-controlled selective quick disconnect for drill ships and semis
  • Proven and reliable acoustic release design
  • Backup mechanical release for ultimate reliability
  • Trigger-sleeve nesting capability for faster rig disconnects not dependent on AHTS support vessels

RAR Plus Specs | Delmar Mooring

The RAR Plus can be equipped with an acoustic telemetry system that uses integrated sensors so you can enjoy real-time continuous monitoring of local line inclination, depth, and strain. The user-friendly graphical interface displays valuable data for on board personnel to use during mooring activities and for the duration of the drilling campaign.
