Marine Coordination

Marine Coordination is the term used for the implementation of VTS technology on an Offshore Windfarm. It is used for the purpose of managing marine traffic during the Construction and Operation & Maintenance phases of the windfarm project lifecycle.
Offshore Windfarms are a hazard to maritime traffic. In addition, due to the radar reflective properties of the turbines, they can cause problems for navigators by creating a large radar echo on the bridge ARPA displays. Therefore, the provision effective monitoring is essential as the on board navigator may be viewing a confusing image.

Many of the early offshore wind farms were located close to the coastline and so the management of crew transfer vessels and other offshore installation vessels during both the Construction and the Operation & Maintenance phases of the wind farm lifecycle could be easily managed from onshore. However, with wind farms moving further offshore, and into deeper water, there is a need for an effective remote management capability in order to ensure that safety is effectively managed.

Effective Marine Coordination

The key objective of the Marine Coordination function of an offshore wind farm is achieving the most efficient use of assets during Construction and throughout the Operation & Maintenance phase. Effective Marine Coordination can provide substantial cost savings during the Construction phase when many vessels and people will be employed to build the offshore wind farm. If people, or vessels, are not in the right place at the right time then time is wasted while offshore workers wait for a transfer to the turbine of to their next task. If such delays are multiipled across the entire workforce then the cost of Construction increases dramatically. An effective Marine Coordination System comprising the right technology with skilled Operators can therefore provide substantial dividends to the Wind farm developer by maximising the working hours offshore while maintaining good health & safety principles. The marine coordination system will usually include a means of tracking the location of each offshore worker to ensure efficient operations and so that the Marine Coordinator can ensure that everyone is accounted for in the event of an incident (See
People Tracking).

Many Marine Coordination Systems use AIS as the principle means of monitoring and tracking vessels. However, effective Marine Coordination is dependent on knowing what is happening offshore and AIS will only present information about AIS equipped vessels. Additional features such as radar and CCTV provide a good means of ensuring that all vessels on the wind farm are visible to the Marine Coordinator and presented on his system. Communication is also essential so that the Marine Coordinator can communicate and provide information to the skipper of each Crew Transfer Vessel and so ensuring the right technical solution for each wind farm project is essential.
