Application of OFFPIPE Software in Submarine Pipeline Laying

The characteristics and capability of ″Submarine Pipeline Installation and Structure Analyses Software - OFFPIPE″ are briefly presented in this paper. Stress calculation and analysis on pipeline laying using SL901 pipelaying vessel at water depth within 17m of E section of Aoshan-Zhenghai submarine pipeline were carried out with OFFPIPE, and the theoretical basis of pipeline laying was provided. It was proved by site laying practice that the analytical results from OFFPIPE were correct, so that OFFPIPE could be used to guide submarine pipeline construction.
