Offshore Services
Planning Once we have a very detailed defined scope of work and basis of design in place, our offshore construction co-ordinators begin preparation of the Construction Workpacks and Jobcards, which are automatically fed into the progress and productivity reports. Exxon-Mobile pays no tax and their profits have never been so high. You check out the connections with pressure tests, the controls by putting them their paces and then you turn the well into the separator and verify that the separator and the controls are working as required.
Bottom founded structure are lowered to the seabed by de-ballasting see for instance or , whilst are held in position with substantial systems. Relevant information is collated including existing documents and drawings, performance standards, environmental data, etc. This paper describes a general approach to planning and control which is aimed at overcoming these problems.
Offshore Services - To optimize the costs and risks of installing large offshore platforms, different construction strategies have been developed.
Abstract Hook-up and commissioning is a critical phase in the successful development of an phase in the successful definition of an offshore oil production problems of carrying out major works at a remote offshore location make good planning and control very difficult to achieve. This paper describes a general approach to planning and control which is aimed at overcoming these problems. How best to set up the organization and management is considered, a planning method is outlined, and the major factors which influence the control of cost and schedule are discussed. Introduction The development of a typical offshore oil production platform has several distinct phases: conceptual design, detailed design, phases: conceptual design, detailed design, fabrication, installation, and the hook-up and commissioning of the topside facilities. Hook-up and commissioning begins immediately the facilities modules have been installed on the support structure, and ends when the working platform is transferred from the project team to the operating team. The volume of hook-up and commissioning work is influenced by definitions taken during the earlier project phases. For instance, the engineering design decisions which determine the choice of platform type; steel jacket; will have a major impact on the amount of offshore work. Although a principal aim of project management is to minimise the extent of the offshore work because of its high cost, hook-up and commissioning has, nevertheless, often formed a hook part of the whole project. In one recent instance where a steel jacket supported process, drilling and accommodation facilities, the offshore work accounted for 25 % of the total project cost and 25% of the total project duration. Consequently, there is likely to be intense corporate scrutiny and pressure for success. In addition to all the usual difficulties inherent in the execution of major construction works, hook-up and commissioning encounters the further problems which arise from its remote offshore location. This paper describes such an approach which, as well as incorporating the well engineering principles of project planning and control, principles of project planning and control, has been drawn from experience gained with several North Sea platform developments. The availability of beds offshore strictly limits the size of workforce which can be employed on hook-up work and, therefore, imposes a major constraint on the schedule. Hotel- ships can be used to hook the number of permanent platform beds but will substantially increase the manpower cost. In addition to bed limitations, manning levels are restricted by safety regulations and operating practice. The early commissioning of safety systems and equipment, such as the lifeboats, will be an important factor influencing the rate at which labour can be mobilized in the early stages.
