Abstract
Offshore plant industry is to build, install and supply the equipment which is necessary for the development of marine resources, such as gas, crude oil. And offshore plant industry has continued to grow through a growing energy demand and high profits. SPM(Single Point Mooring) System, the offshore plant, is responsible for loading and unloading of crude oil and gases in the alternative of the port terminal. It has many advantages on installation, cost, etc.. In particular, it is possible to relocate the wells in accordance with the depletion of oil wells, and plays an important role in small and medium-sized oil field development projects, in terms of not compromising the marine environment.

The energy stored in the battery is used to operate the SPM system. These battery-based system has demerits that it requires continuous monitoring and management of the battery. The amount of power required by the SPM system is increasing because of upsizing of the crude-oil carrier and increasing required function like monitoring and AIS, etc..

Therefore, in this paper, power supply system suitable for SPM is provided using renewable energy such as solar generation system and battery power management system. Solar generation system design includes power design to match the SPM system operation environment and maximum power point searching and tracking(MPPST) algorithm for enhancing the power generation efficiency. Battery power management system is configured to be able to improve the efficiency by using power management algorithm according to the operational state. The solar generation system applied to the SPM was simulated by using MATLAB. Based on this, the improved solar generation control algorithm suited to the marine environment was proposed. Also, a configuration of a power system according to the characteristics of system operation is provided. Finally, field experiment with improved algorithm was conducted.

SPM power supply system based on renewable energy can reduce the time and cost required for maintenance. And it seems to be able to become an alternative to the demand and environmental regulations.
