| BSI | 2019 | 134 |
This document specifies requirements and provides recommendations applicable to fixed, floating and grounded concrete offshore structures for the petroleum and natural gas industries and for structures supporting nationally-important power generation, transmission or distribution facility. This document specifically addresses
-
the design, construction, transportation and installation of new structures, including requirements for in-service inspection and possible removal of structures,
-
the assessment of structures in service, and
-
the assessment of structures for reuse at other locations.
This document is intended to cover the engineering processes needed for the major engineering disciplines to establish a facility for offshore operation.
