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)

COmputer Assisted Shipping Traffic Database Runs in MapInfo (GIS) Easy search and display function Presents details on shipping movements in the North Sea:
- Route Description- CPA to a predefined location - Vessel Type- Vessel Size- Volume of vessels- Port To/From- Standard deviation of routes- Age and Speed of vessels
