UNE-EN ISO 19900:2019

This document specifies general principles for the design and assessment of offshore structures subjected to known or foreseeable types of hazards and actions. These general principles are applicable worldwide to all types of offshore structures, including fixed structures as well as floating structures, and to all types of materials used including steel, concrete and aluminium.

This document specifies principles that are applicable to design and assessment for all phases of the life of the structure, including:

the successive stages in the construction of the structure (i.e. fabrication, transportation, and installation);

its service in-place, including use and modifications during its planned life and any extension of its life;

its decommissioning.

This document contains provisions for new build structures. Most of the provisions also apply to assessment of existing structures, wherever feasible, which is also described in this document.
