CALM Buoys

The CALM is the most popular and widely-used type of offshore loading terminal with more than 500 systems installed to date. CALM buoys have been deployed worldwide for a variety of applications, water depths and vessel sizes ranging from small product carriers to Very Large Crude Carriers (VLCC) and Ultra Large Crude Carriers (ULCC). Because of safe and easy berthing and un-berthing operations, the CALM has been adopted as the preferred method of mooring and for offshore marine terminals.
