3. 3 Background It has been registrated an increased number of incidents in the North Sea between passing merchant vessels and offshore installations during the 1990’s. HSE-UK/ DoT: Introduced a general requirement to carry out collision risk studies. (Later followed up by NPD) No reliable data was available or possible to collect within short time. 1995: The COAST project was kicked-off to establish a comprehensive shipping movement database in order to obtain a more accurate and cost effective mean to obtain information on shipping.
