Metadata: 2002, Safetec UK Ltd, Gunfleet Sands 1 and 2, Collision Risk Assessment
Abstract:
Enron Wind Gunfleet Ltd. (Enron Wind) have commissioned Safetec UK Ltd (Safetec) to undertake a collision risk assessment of the Gunfleet Sands area. This assessment assists to identify any concerns within the area in order that the proposed wind turbine locations and cable laying / routing can be planned with due regard to minimising the impact upon the environment, and improving working efficiency within the project. The outcomes of the study identified there was a large amount of traffic (10,222 vessels per annum) passing within 10nm of the proposed development area. However, it is noted that approximately 99% of this traffic passes at least 3.7nm from the area of interest, which is considered to be a safe passing distance. This passing traffic is associated with the ports/docks accessed via the Thames such as Tilbury dock, Thames port and Medway port, and due to the nature of their current course these vessels tend to naturally avoid the area of interest as they navigate between the sandbanks and associated shallow waters via the recommended deepwater routes through the Thames Estuary. It is also considered that due to the position of the proposed development area within the Gunfleet Sands, vessels passing on the closed passing route (No.1) will be unaffected by the development as they already navigate to avoid the Gunfleet Sands.

| Lineage | Lineage includes the background information, history of the sources of data, data quality statements and methods. | Identification of Shipping Pattern will be assessed utilising the COAST database which has been developed by Safetec on behalf of the DETR, HSE and UKOOA. This data source contains details of route positions, traffic volumes and vessel size/type distributions for all merchant shipping routes passing through UK waters. It should be noted that the database does not include details of routes which are termed as non-routine traffic e.g. fishing vessels, traffic to mobile drilling units, etc. Generally the COAST database carries information of all route based traffic that are over 10m in length or 100 GRT (gross registered tonnage). It is also noted that for this study the database has been updated based on survey data recently recorded in the Thames Estuary by Dover CNIS and Port of London Authority. Determination of Collision Frequency was performed using the data contained within the COAST database as input to the COLLIDE 2.60 model. The model developed was also based on site specific environmental and wind turbine tower details. |
