Summary
Introduction
A new-build FPSO project may take 3–4 years to complete. For a successful project, a variety of steps must be carefully considered and implemented, including front-end engineering, design development, performance specifications, detailed specifications, vetting and selection of candidate yards and contractors, contract award, detailed engineering, construction, precommissioning (dock trials), sea trials, delivery, onsite commissioning, and contract acceptance.
Ship-shaped offshore units for developing offshore oil and gas fields in deep waters have been in existence in fair numbers since the early 1970s. In recent years, the complexity and size of ship-shaped offshore units have been increasing gradually; therefore, it is only natural that the issues related to designing, building, and operating these systems arise or may need revisiting in specific circumstances for the purposes of achieving a high level of the system integrity.
Moreover, in contrast to trading tankers and other types of offshore platforms, internationally agreed standards for ship-shaped offshore units are in a state of progress. In Chapter 3, we discuss how the classification societies (ABS 2004; BV 2004; DNV 2000, 2002; LR 1999) and institutions (API 2001) have, in recent years, developed guidance and rules specifically for floating, production, storage, and offloading systems (FPSOs), but there, for example, is not the unified approach to the rules that now exist for trading tankers (IACS 2005).
The requirements for designing and building ship-shaped offshore units are, in principle, different from the requirements of trading tankers because of the high level of onsite reliability necessary for long periods without the possibility of dry-docking.
