JIP tackles interaction of deepwater moorings, risers, offloading

摘要

Predicting the motions and interactions of remote production and offloading sys-tems demands an analytical approach that incorporates coupling effects. This is particularly the case for complex scenarios involving a dedicated dry-tree platform (spar or TIP), with production fluids transferred to an FPSO, with the oil then offloaded to a catenary anchor leg mooring (CALM) buoy via steel or flexible offloading lines and onwards to a shuttle tanker through offloading hoses. In such cases, the capability to model realistic and reliable motion characteristics can have a critical influence on the extreme and fatigue response characteristics of risers, moorings, and offloading lines.
