47、ionGeneralThis document was compiled by the UMSIRE Joint Industry Project (JIP) group with the aim of addressing the increasing difficulties in installation of high-functionality subsea umbilical terminations (SUTs). The document focuses on highlighting the implications of increasing size and weight
48、 on installation. The JIP committee was composed of a representative cross section of experienced industry personnel from umbilical and umbilical termination assembly (UTA) manufacturers, installation contractors, and operators. UTA is a subassembly of SUT. While there are widely accepted codes and
49、standards for the design of UTA and its subsystems, such as materials, core connector type, tubing specification, corrosion protection, and lifting arrangements, none of these standards specifically address the substantially increased risks incurred during packing, handling, and installing umbilicals with large UTAs. The JIP deliverables are two API documents, API Technical Report 17TR9, Umbilical Termination Assembly (UTA) Selection and Sizing Recommendations, and API Technical Report 17TR10, Subsea Umbilical Termination (SUT) Design Recommendations.
