2.5 Standards and Guidance Notes for Concrete Structures 2.5.1 Introduction
ОглавлениеThe international recognised standard for designing, fabricating and maintaining offshore concrete structures is the ISO 19903 (ISO 2019b), originally introduced in 2006 and updated in 2019. The ISO standard was based on the Norwegian standard NS 3473 with input from other relevant standards. Previously, the Department of Energy introduced a set of Guidance Notes for offshore concrete structures in 1974 which was significantly updated in the fourth edition, published in 1990 (Department of Energy 1990) and supported by a background document on concrete (HSE 1997). The emphasis of these documents, however, was on design and construction of offshore concrete structures with limited sections dealing with inspection and repair. In addition, the Norwegian standard NORSOK N‐005 (Standard Norge 2017b) has some international status. NORSOK N‐005 includes a special annexe covering inspection of concrete structures. The relevant sections of ISO 19903, the Department of Energy Guidance Notes and NORSOK N‐005 are discussed below.
