Scheme Design of Intelligent Vessel Dispatching and Personnel Management System for Offshore Wind Farm

Abstract

[Introduction] As a new topic in the field of offshore wind farm, the management, command and dispatch of personnel and vessels is attracting significant interest. This paper introduces an intelligent vessel dispatching and personnel management system for offshore wind farm, which is first creation of its kind in China. [Method] It mainly included three aspects: (1) Efficient command and dispatch system. Efficient command and dispatch was achieved by very high frequency (VHF) marine intercom system, which realized steady intercom communications. The marine intercom system based on maritime high-frequency VHF can be achieved the steady intercom communications. With the automatic identification system (AIS) receiver and the maritime radio station, the identity information and geographical location of the surrounding vessels can be obtained. Meanwhile, the records of the vessels entering the warning zone can be archived and those vessels will also be interrogated. If any drowning staff was spotted, alerting signal would be immediately sent to the onshore command center; (2)The sea area real-time monitoring contained two parts. A far-infrared thermal imaging camera was used to realize remote monitoring for operating conditions of the wind farms. Meanwhile, two cameras and meteorological sensors were mounted on the anemometer tower, which could be used to monitor marine and surge conditions of the neighboring sea area of the wind farm; (3)An accurate marine weather forecasting sub-system was also adopted, which was capable of forecasting on-site environmental conditions such as wind speed, waves, and surges a week ahead. In addition, it can also realized tracking and forecasting of typhoon. [Result] The results suggest that the system is reliable and can realize effective management of personnel as well as vessels, and hence reduces the costs of construction, operation and maintenance concerning the offshore wind farm. [Conclusion] Therefore, the system plays an important role in enhancing the safety production management as well as improving the operation and maintenance efficiency of the offshore wind farm.
