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. HOHN Offshore however, depending on each specific case, is able to propose a tailor made solutions to fit every customer need.
Double Carcass/DC Floating type
Our OCIMF 2009 Double Carcass hoses are built with two carcasses in order to prevent any possible leakage of product in the first carcass, which can be possibly detected by means of an high reliable mechanical leak detector, assuring the long lasting service life of the hose. The hoses are built with steel cords reinforcements (first carcass), helix steel body and polyester cords reinforcements (second carcass) with floating material (foam cell) in order to guarantee the correct reserve buoyancy, depending from the positions and the function they have within the hose string. They are made of multiple plies of high performance materials to resist to harsh marine environment conditions in long lasting applications.
