What is a Catenary Anchor Leg Mooring CALM buoy?
A Catenary Anchor Leg Mooring (CALM) buoy is a description of how the buoyed platform is anchored to the seabed. CALM Buoys can be used offshore in deep water to all…ow ships to offload or load liquid cargo (e.g. crude oil) without the need for a Jetty extension into the deeper water. The key word in this descriptive name is catenary - which refers to the angled lines that connect the buoy to the seabed and hold it in position. Four or six anchors are "Set" to the sea floor in a pattern around the buoy position and the lines are fixed to the bottom of the buoy so as to position the buoy in the center of the anchors. No matter which direction the wind/waves drive the floating buoy, it is held in position by the anchor on the windward side of the buoy. (MORE)
