It was agreed to commence the survey at the identified critical sections – and evaluate along the operation taking the weather and progress in to consideration. The purpose of the survey was to determine the degree of protection provided to the cables based on the burial depth into the seabed, and the survey data from the survey completed summer 2006. In other words there are now to independent survey to clarify the seabed cover over the cables along the cable route in all positions along the route where a survey has been completed. The correlation between the two survey has indicated some cables which remain at risk, and others which has gained burial as and outcome of unexpected sediment movement.

The survey was planned to take place in July and August – months that are normally known for having workable weather conditions. Summer 2007 proved to be different and significant WOW was experienced. Vessel arrived at site 03 July 2007 and departed from Ramsgate the 22nd of August 2007. The ROV suffered from a short circle fault in the main electronics – wherefore equipment was declared offshore for a few days during the survey period. Full survey was planned for in an order of priority, pending on weather, having completed the critical sections and approx 75% of the cable survey, the remaining survey was cancelled due to the adverse weather conditions experienced at the time. Below sections of array cables was not surveyed: • A3 – A4 • E1 – E2 • E3 – E4 • F1 – F2 • D3 – D4 https://www.marinedataexchange.co.uk/details/800/summary A link to the web service or dataset. https://www.marinedataexchange.co.uk A link to the general host site.
