The standard range of HOHN’s single and double carcass hoses is widely utilized on a variety of single point moorings (SPM) including CALM and SALM buoy terminals. Manufactured to the latest OCIMF 2009 certification, these hoses are the principal means for tanker loading and discharge operations offshore since the 1960’s. We are DNV.GL certificated on 2016 year.
HOHN is able to propose tailor made submarine hose string solutions to fit every customer need. All our marine hose are designed and manufactured according to GMPHOM 2009.
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.
