The Hydraulic Release Shackles (HRS) are used for lifting and positioning structures both subsea as well as on the surface. The HRS is mostly used in areas with limited access when it’s difficult for personnel to fasten or release shackles connections in a safe and efficient way. The Hydraulic Release Shackle fastens and releases the shackle automatically with an hydraulically operated pin. The HRS can be remotely operated, which makes sure the human interaction is being reduced, making the shackle operation a safer process. Besides increasing the safety, the hydraulic pin can be operated faster than conventional handling, making the fastening of the shackle more efficient.
ABOUT THE HYDRAULIC RELEASE SHACKLE
The Hydraulic Release Shackle opens and closes with a hydraulically operated pin. It can be remotely operated via a Hydraulic powerpack or by ROV intervention if the need arises. The HRS as a standard is suitable for 500 meters of water depth and has several optional methods available to improve operational capability, which are:
• Hot Stab for easy ROV interaction as primary of back-up connection
• Secondary back-up cylinders
• Accumulators for stored hydraulic energy
• Mechanical back-up release to allow for back-up release activations if required
EXTENSIVE TRACK RECORD HYDRAULIC RELEASE SHACKLE
Our Hydraulic Release Shackles have been a part of our fleet since 1998. To this date, we have sold over 500 shackles in ranges from 17.5t to 2,000t of which around 200 of those units were ROV capable versions. In the rental part of the business we have been involved in over 100 projects onshore and offshore with over 2,300 rental days achieved.
