API TR 17TR9

Abstract

This technical report identifies and describes: — technical, commercial, and installation risks associated with high-functionality umbilicals and umbilical terminations [resulting in large and heavy umbilical termination assemblies (UTAs)], especially with respect to installation; — implications of decisions made early in the umbilical and subsea umbilical termination (SUT) planning, selection, and design phases, to ease the manufacturing, handling, and final umbilical/UTA installation; — guidance on specification and sizing of umbilical terminations, including overall size, weight, and handling requirements. This document is intended to aid with informed decision making and selection of optimal choices during the early design phase of field development. The primary purpose of this document is to be a reference guide during the early field development planning stage to ensure that due consideration is given to the implications of the size of UTAs and possible consequences during installation. Guidelines for the design of UTAs are included in API 17TR10.
