Abstract:

Bonded hose is the important equipment for oil transportation in catenary anchor leg mooring (CALM) system. Bonded hose is made of elastomer with additional layer such as textile layer impregnated with rubber, steel wire, etc. to improve the axial tensile and bending strength of the hose. There is little research on the bonded hose for offshore oil and gas field in China so far. We present the research on two types of bonded hoses in CALM system: floating hose and marine hose. The investigations on structure and length selection and configuration of two types of hoses are carried out. A design approach for structure selection and configuration determination is proposed. Taking marine hose as an example, the static and dynamic analysis is presented.

Key words: single point mooring, catenary anchor leg mooring, bonded hose, floating hose, marine hose
