This Standard sets forth requirements and guidance pertaining to the various sea operations involved with fixed and floating offshore structures. As sea operations are complex activities specific to each application, these requirements should be reviewed for each application to ensure that the particular circumstances are adequately addressed.
1) This Standard specifically addresses concrete gravity base structures, steel jacket structures, and jackup structures but is generalized to all offshore structure types where possible. Table 1 identifies the applicable clauses and the crossreferencing among them. Further specifics related to operations for areas where ice is present are addressed in Clause 8. Sea operation aspects of many structures used in arctic regions, such as the fill-retention structures addressed in CSA S472, are similar to those for concrete gravity bases.
2) This Standard does not provide precise requirements applicable to all sea operations. It is meant to provide users involved in such operations with guidance on aspects to be considered, and it establishes minimum requirements for routine operations.
3) No code of practice can substitute for good planning and the use of knowledgeable, competent personnel. Sea operations with offshore structures can involve large numbers of people and equipment operating in concert to achieve a specific goal. A prime consideration of any well-planned operation is to ensure the safety of personnel and equipment. This Standard does not diminish the responsibility of all personnel to consider and plan for all reasonably foreseeable problems.
