本技术报告确定并描述了:-与高功能性脐带电缆和脐带电缆终端相关的技术、商业和安装风险[导致大型和重型脐带电缆终端组件（UTA）]，尤其是在安装方面；-在脐带缆和水下脐带缆终端（SUT）规划、选择和设计阶段早期做出的决策的影响，以简化制造、搬运和最终脐带缆/UTA安装脐带缆终端的规格和尺寸指南，包括总尺寸、重量和搬运要求。 本文件在早期油田开发规划阶段作为参考指南，以确保适当考虑UTA规模的影响以及安装期间可能产生的后果。本手册旨在作为最终用户和运营商、UTA和脐带缆制造商、安装商以及前端工程设计（FEED）公司的参考指南。其目的是，在开始SUT设计和功能定义之前，该文件将使UTA设计师能够提前解决当前固有的安装困难。 本文件还将用作参考文件，以便进行审查，以确保安装风险已作为SUT设计和运行审查的一部分，在个案基础上得到适当考虑。

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 acts as 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.It is intended to be used as a reference guide by end users and operators, UTA and umbilical manufacturers, installers, and front-end engineering design (FEED) companies. The intention is that the document will enable the currently inherent installation difficulties to be addressed up front by the UTA designers, prior to commencing SUT design and functionality definition. It is also intended to be used as a reference document to enable reviews to be undertaken to ensure that installation risk has been properly considered as part of SUT design and operations reviews on a case-by-case basis.
