CATENARY ANCHOR LEG MOORING (CALM) - FLOATING

A Catenary Anchor Leg Mooring (CALM), also known as Single Buoy Mooring (SBM) or Single Point Mooring (SPM), is a dynamic loading and offloading buoy, that serves as a mooring point for tankers and as link between the Pipe Line End Manifold (PLEM) and shuttle tankers. They’re typically used both in shallow and in deep waters for import and / or export of crude oil and oil byproducts from / to oilfields or refineries. For what it concerns the hoses strings, they’re made by two main systems, floating and submarine. Floating lines can be composed by one single string or two parallel strings depending on the flow rates and products needed. The strings can be equipped with Marine Breakaway Coupling (MBC) and are generally equipped with a set of marine ancillaries (cam lock coupling, butterfly valve, spool piece, etc.) at the Tanker Rail Hose End.

The configuration hereunder indicated is the most common hose string configuration. Bassi Offshore however, depending on each specific case, is able to propose a tailor made solutions to fit every customer need.
