International Standard Iso 19901-1 «DIRECT»

: These are frequent events expected during the standard service life of a structure, used primarily for operational planning and fatigue analysis.

is the primary international standard for determining meteorological and oceanographic (metocean) design and operating conditions for offshore structures in the oil and gas industries. It provides the framework for characterizing environmental factors—such as wind, waves, and currents—that impact the safety and integrity of offshore platforms throughout their entire lifecycle. Core Objectives international standard iso 19901-1
