This part of ISO 19901 gives general requirements for the determination and use of meteorological andoceanographic (metocean) conditions for the design, construction and operation of offshore structuresof all types used in the petroleum and natural gas industries.The requirements are divided into two broad types:— those that relate to the determination of environmental conditions in general, together with themetocean parameters that are required to adequately describe them;— those that relate to the characterization and use of metocean parameters for the design, theconstruction activities or the operation of offshore structures.The environmental conditions and metocean parameters discussed are:— extreme and abnormal values of metocean parameters that recur with given return periods that areconsiderably longer than the design service life of the structure,— long-term distributions of metocean parameters, in the form of cumulative, conditional, marginal orjoint statistics of metocean parameters, and— normal environmental conditions that are expected to occur frequently during the design servicelife of the structure.Metocean parameters are applicable to:— the determination of actions for the design of new structures,— the determination of actions for the assessment of existing structures,— the site-specific assessment of mobile offshore units,— the determination of limiting environmental conditions, weather windows, actions and actioneffects for pre-service and post-service situations (i.e. fabrication, transportation and installationor decommissioning and removal of a structure), and— the operation of the platform, where appropriate.
