Offshore structures are a mobile or fixed installation which includes a pipeline attached thereto, which is to be or has been used, while standing or stationed in relevant waters with a purpose to explore petroleum and natural gas.
ISO 19901-5 specifies requirements for controlling the weight, and centre of gravity (CoG) by means of mass management during the engineering and construction of structures for the offshore environment. ISO 19901-5 guidelines specify provisions that are applicable to offshore projects that include structures of all types (fixed and floating), and materials. These structures can be completely new installations or modifications to existing installations. Maintaining the weight control of existing installations is not part of the main body of this part of ISO 19901-5, but some guidance on this is included in Annex G.
ISO 19901-5 for specific requirements for offshore structures is useful for:
The management of offshore structures involves the application of engineering expertise, and knowledge to provide the measures needed to meet the objectives set by the organizations involved in the project development.
ISO 19901-5 provides you with the quality requirements for reporting of weights, and centres of gravity, requirements for weight reporting, basis for overall project weight reports or management reports for all weight control classes.
ISO 19901-5 also specifies requirements for weight and load budgets, specifies the methods, and requirements for the weighing, and the determination of weight, and CoG of major assemblies, along with the requirements for weight information from suppliers, including weighing of equipment, and bulk materials for offshore installations.
