This part of ISO 19901 specifies methodologies for: a) analysing, designing and evaluating stationkeeping systems for floating structures used by the oil and gas industry to support the following applications: - production; - storage; - drilling and production; - production and storage; - drilling, production and storage. b) assessing site specific applications of stationkeeping systems installed on mobile offshore units (e.g. mobile offshore drilling units, construction units, and pipelay units). For stationkeeping systems used in conjunction with the floating structures listed under 1a), this part of ISO 19901 is also applicable to all aspects of the life cycle and includes requirements relating to the manufacture of mooring components, as well as considerations for in-service inspections. This part of ISO 19901 is applicable to the following types of stationkeeping systems, which are either covered directly in this document or through reference to other guidelines: - spread moorings (catenary, taut-line and semi-taut-line moorings); - single point moorings, anchored by spread mooring arrangements; - dynamic positioning systems; - thruster-assisted moorings. Descriptions of the characteristics and of typical components of these systems are given in A.1. The provisions of this part of ISO 19901 mainly address spread mooring systems composed of steel chain and wire rope. This document also provides guidance on the application of the methodology to synthetic fibre rope mooring systems, and includes additional requirements related to the unique properties of synthetic fibre ropes. The provisions of this document do not apply to the vertical moorings of Tension Leg Platforms (TLPs) or Single Anchor Leg Moorings (SALMs). The methodology described in this part of ISO 19901 identifies a set of coherent analysis tools that, combined with an understanding of the site-specific metocean conditions, the characteristics of the floating structure under consideration, and other factors, can be used to determine the adequacy of the stationkeeping system to meet the general requirements described in 5.1.
