The Next Generation in Mooring: the Delmar Quick Release

DQR brochure

Station-keeping in harsh environment is a challenge. Sudden tropical storms, ice flows, or well containment issues can make it necessary for a rig to suddenly leave location. Continuing with its strong tradition of developing innovative mooring solutions, Delmar Systems introduces the Delmar Quick Release (DQR). The DQR is an in-line mooring component with a simple mechanical release that allows the rig to safely and efficiently offset or depart from a moored location in an emergency with or without the use of support vessels. This allows the rig to be offset and leave location without waiting on vessels to mobilize and arrive. Additionally, the DQR can be reconnected in the field without recovery to shore by simply replacing the shear pin.

The DQR can be used with any anchor foundation and allows for safe mooring of DP rigs as well as traditional moored rigs. This enables DP MODUs with mooring capability to operate in shallow water and still quickly depart location under their own propulsion prior to a cyclonic event without needing support vessels to disconnect the moorings.

  • Simple and reliable
  • Activated by rig or AHV
  • No additional special equipment needed
  • Allows rig to be quickly moved off location
