This project examines the likely sediment disturbance effects arising from the proposed installation methods for laying inter-turbine and export cables for the London Array Offshore Wind Farm as carried out by ABPmer. Various installation methods were assessed including ploughing, jetting, cutting and trenching. An analysis of the impacts to sediment disturbance caused by each of the installation methods is provided within this project. Supporting survey data was required from a benthic survey (for particel size data for surficial sediments), geophysical survey, geotechnical survey and metocean survey at the London Array site. This was provided from those surveys that had been carried out at the site of the proposed London Array offshore wind farm.
