Petroleum and natural gas industries - Fixed steel offshore structures (ISO 19902:2007/Amd 1:2013)
This International Standard specifies requirements and provides recommendations applicable to the following types of fixed steel offshore structures for the petroleum and natural gas industries: caissons, free-standing and braced; jackets; monotowers; towers. In addition, it is applicable to compliant bottom founded structures, steel gravity structures, jack-ups, other bottom founded structures and other structures related to offshore structures (such as underwater oil storage tanks, bridges and connecting structures), to the extent to which its requirements are relevant. This International Standard contains requirements for planning and engineering of the following tasks: a) design, fabrication, transportation and installation of new structures as well as their future removal; b) in-service inspection and integrity management of both new and existing structures; c) assessment of existing structures; d) evaluation of structures for reuse at different locations.

Foreword
ISO (the International Organization for Standardization) is a worldwide federation of national standards
bodies (ISO member bodies). The work of preparing International Standards is normally carried out
through ISO technical committees. Each member body interested in a subject for which a technical
committee has been established has the right to be represented on that committee. International
organizations, governmental and non-governmental, in liaison with ISO, also take part in the work.
ISO collaborates closely with the International Electrotechnical Commission (IEC) on all matters of
electrotechnical standardization.
The procedures used to develop this document and those intended for its further maintenance are
described in the ISO/IEC Directives, Part 1. In particular the different approval criteria needed for the
different types of ISO documents should be noted. This document was drafted in accordance with the
editorial rules of the ISO/IEC Directives, Part 2. www.iso.org/directives
Attention is drawn to the possibility that some of the elements of this document may be the subject of
patent rights. ISO shall not be held responsible for identifying any or all such patent rights. Details of any
patent rights identified during the development of the document will be in the Introduction and/or on
the ISO list of patent declarations received. www.iso.org/patents

NOTE There have been historical differences in the usage and understanding of the terms “jacket” and
“tower”, particularly between the USA and Europe. The difference in such understanding of the terms
has no significant impact on the application of this International Standard as long as the differences in
structural behaviour are considered in the analyses of the different structures.

“tower”, particularly between the USA and Europe. The difference in such understanding of the terms
has no significant impact on the application of this International Standard as long as the differences in
structural behaviour are considered in the analyses of the different structures.
NOTE 2 There have been historical differences, which continue to exist, in the use and understanding
of the term “caisson”. In the offshore oil and gas industry this term, together with its variants “braced
caisson” or “free-standing caisson” (see, respectively, 3.7 and 3.22), has traditionally been used to
refer to a particular type of minimum fixed structure, where the main component is a relatively large
diameter tubular member, with or without additional lateral support, intended to satisfy various
functional requirements such as supporting one or more wells, or supporting small decks and associated
facilities. Conversely, in the geotechnical arena the term “caisson” has traditionally been used to refer to
“foundation caisson”, i.e. foundation component /system consisting of shorter and more rigid chamber
of larger diameter or larger lateral dimensions than the caisson structures described above.
Clause 17 covers the geotechnical design of long slender piles (i.e. satisfying the condition L/D ≥ 10,
where L is the length embedded in the soil, and D is the outside diameter) for fixed steel structures.
The provisions of that clause apply also to braced or free-standing caisson structures with L/D ≥
10. However, the content of Clause 17 does not apply to the design of short and rigid, large diameter
foundations with L/D < 10. Guidance on the geotechnical design of this type of foundations is within the
scope of ISO 19901-4.

a correspondence factor is introduced to address any differences in the derivation of the action and
resistance factors of different standards.

A deterministic fatigue analysis method is not recommended for final checking of structures in harsh

general applications. Guidance on dynamically responding structures is given in 16.4.3 and 16.6.4.
