CALM buoys have grown to become one of the leading offshore loading terminals and are being deployed worldwide for a wide range of applications and vessels. They're commonly used for offloading crude oil from floating production storage and offloading units in deep water. 

CALM buoys are secured to the seabed by anchors or piles and are typically located in water between 20-100m where they're connected to a storage facility or offshore production farm. At least one hawser secures the tanker to a turntable which is mounted by a slewing bearing to the top of the buoy. Liquid is then transferred via the CALM buoy to/from the tanker via floating and subsea hose systems.

Strategically located bases:

By utilising strategically located bases around the geographical areas where there are high levels of CALM buoys, Fendercare Marine has an advantageous position to offer a fully comprehensive CALM buoy service. A structured and formalised approach is created by utilising local knowledge and group resources to deliver a safe and efficient service across all operations.
