Floating offshore facility, power supply method for floating offshore facility

Abstract

Electric power generation facilities (40), (50) for supplying electric power to a production facility (30) and to facilities other than the production facility are configured with: a first-group electric power generation facility (40) which supplies electric power to the production facility (30), and which is disposed in a production facility region (Rp) on an upper deck (3); and a second-group electric power generation facility (50) which supplies electric power to facilities other than the production facility, and which is disposed in a safety region (Rs) other than the production facility region (Rp). Consequently, the space required for the electric power generation facilities in the production facility region on the upper deck is reduced, whereby the space for the facility for production as an offshore facility is increased, and risks are spread in the event of trouble with the electric power systems of the electric power facilities.

Description

technical field [0001] The present invention relates to floating offshore equipment and a power supply method for floating offshore equipment. More specifically, it relates to a space for power generation equipment that can reduce the space for production equipment on the upper deck and can increase the use of offshore equipment. A floating-body type offshore facility and a power supply method for the floating-body type offshore facility that can disperse risks in the event of a failure in a power system in a power generation facility in a space for the facility to be produced. Background technique [0002] Equipped with oil / gas production equipment and loading and unloading equipment, FPSO (floating body production storage and offloading equipment), FSO (floating body storage and offloading equipment) or FSU (floating body storage equipment) used to maintain a position at a specific offshore installation site for a long period of time ), floating offshore equipment such as ...

AI Technical Summary

Problems solved by technology

Furthermore, there is a problem that if a failure of the power system occurs in the power generation equipment 40X in the production equipment area Rp installed on the upper deck 3, not only the production equipment 30, but also the production equipment 30 constitutes a floating offshore system. The power supply of other equipment of equipment 1X (for example, the unloading device or the power supply for residential areas, etc.) will also be completely stopped.

[0009] In this power generation facility, when a failure occurs in some of the power generation units, power is supplied from other power generation units, so the power supply to each device can be ensured for failure of the power system, but it cannot solve the problem of the upper deck unique to offshore production facilities. The problem of securing the space of the area for production facilities mentioned above, and the problem of how to deal with the difference in the subject of design of the power generation facilities for production facilities and other power generation facilities, and the timing of the determination of each power generation facility

[0010] In addition, in the case of new floating offshore equipment instead of VLCC modification, there are many cases where propellers such as propellers and propulsion devices for driving the propellers are not equipped, and since they do not have their own moving mechanism, they must be towed or Transferring to the production site using a heavy cargo carrier, there is also the problem that the initial transfer cost is very high

[0011] In addition, although there are cases where propulsion by a low-speed diesel engine is performed like a normal tanker, in this case, there is a problem that after arriving at the production site, the low-speed diesel propulsion device used for propulsion cannot be disassembled and becomes a waste product after use.
