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.

The COAST databases are subject to ongoing updates to maintain the databases as a ”live” and accurate tool. (COAST Fund)
