This example demonstrates the analysis of a floating hose system connecting a semi-sub and an FPSO, approximately 438m apart. The system consists of 52 flexible hose sections configured in a semi-circular shape. The sections have a relatively large diameter of 800mm due to buoyancy, which reduces to 400mm at the end of each section. Each section is 11.5m long, leading to a total hose length of 598m. The whole system is situated in 1000m of water.
The analysis is performed in several stages. The initial configuration of the system is established in a quasi-static analysis where the general shape of the floating hose is established before any dynamic loading is applied. A quasi-static approach is adopted due to the sensitivity of the buoyancy forces to any small displacements in the vertical direction. The initial analysis also includes static current loading.
A single master template file is then used to generate several regular wave input files of varying wave period. After the individual regular wave simulations have been performed, the relevant results are assembled centrally using the summary collation facility.
