Abstract
Offloading hoses/flexible pipes are used to transfer compressed natural gas (CNG) from an intermediate floating CNG storage unit-floating storage and offloading unit (FSO) to CNG vessel. The floating hoses are subjected to environmental loads that are mainly waves, current, and vessel motions from both the FSO and the CNG vessel.

As a part of European Commission Horizon 2020, GASVESSEL project develops offshore transport and distribution technologies for natural gas. In the present study, the feasibility of an offshore loading/unloading system of CNG transportation system in the Barents Sea is investigated.

Numerical simulations are performed by using the software RIFLEX under SIMA workbench. Critical responses such as curvature and axial forces are checked. For the new offloading hose, it is important to check the combined bending-tension loading capacity. The results show that the specified hoses/flexible pipes of the loading/unloading system has ample capacity for the considered operating conditions.
