General

These Guidance Notes provide guidance for the effective management of DP operations for Self-Elevating Units (SEU). This document is not meant to replace or supersede any rules, regulations, or operational manuals. The information presented here is compiled from various industry sources and from experience not previously available in the public domain. This document is not intended to address all aspects of DP operations for SEUs, but rather presents a collection of best practices with a focus on important DP operational themes aimed at effective DP operations and a reduction in DP related incidents.

Self-elevating units (SEUs) equipped with dynamic positioning systems include units for construction, wind turbine IMR (installation, maintenance, and repair), accommodation, well services, and other non-drilling activities. The term 'liftboat' is sometimes used in some geographic areas or by some companies to describe SEUs. Thus the DP operations for SEUs are typically limited to repositioning operations and jacking operations. This document provides guidance on these specific operations.
