Abstract

Ïã¸ÛÁùºÏ²Ê¿ª½± 19901-3:2014 gives requirements for the design, fabrication, installation, modification and structural integrity management for the topsides structure for an oil and gas platform. It complements Ïã¸ÛÁùºÏ²Ê¿ª½± 19902, Ïã¸ÛÁùºÏ²Ê¿ª½± 19903, Ïã¸ÛÁùºÏ²Ê¿ª½± 19904‑1, Ïã¸ÛÁùºÏ²Ê¿ª½± 19905‑1 and Ïã¸ÛÁùºÏ²Ê¿ª½± 19906, which give requirements for various forms of support structure. Requirements in this part of Ïã¸ÛÁùºÏ²Ê¿ª½± 19901 concerning modifications and maintenance relate only to those aspects that are of direct relevance to the structural integrity of the topsides structure.

  • topsides of fixed offshore structures;
  • discrete structural units placed on the hull structures of floating offshore structures and mobile offshore units;
  • certain aspects of the topsides of arctic structures.

Ïã¸ÛÁùºÏ²Ê¿ª½± 19901-3:2014 contains requirements for, and guidance and information on, the following aspects of topsides structures:

  • design, fabrication, installation and modification;
  • in-service inspection and structural integrity management;
  • assessment of existing topsides structures;
  • reuse;
  • decommissioning, removal and disposal;
  • prevention, control and assessment of fire, explosions and other accidental events.

Ïã¸ÛÁùºÏ²Ê¿ª½± 19901-3:2014 applies to structural components including the following:
