  1. COAST Norway v.2002(COmputer Assisted Shipping Traffic Database)Bjørn Øygarden

  2. COAST • Background • COAST ? • Development • Areas of Use

  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.

  4. Background Cont. • 1996: COAST UK V.1 (HSE-UK, DoT) • 2002: COAST Norway v2002 (OLF) • 2002: COAST Singapore Strait • 2003: COAST Venezuela/ Gulf of Paria (ConocoPhilips) • 2003: COAST Brazil (Petrobras), Pending The COAST databases are subject to ongoing updates to maintain the databases as a ”live” and accurate tool. (COAST Fund)

  5. COAST ? • 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

  6. COAST Output Report Route Distribution Size Distribution

  7. COAST Development Port Log Data Radar/ ManualData Collection Other Traffic Data COAST Database

  8. COAST Norway - Raw Data Plot Oseberg/ Troll: 7 days Example Plot

  9. Ekofisk Valhall COAST Norway - Raw Data Plot Ekofisk Area: 40 days radar survey

  10. Example of radar plots from Navtek, 6 days in April 2002

  11. Areas of Use: • Ship to Installation Collision Frequency and Impact Studies- Platforms- Wind Farms- Fish Farms • Ship to Ship Collision Risk Studies • Power Cable and Oil/Gas pipeline laying studies • Grounding Assessments • Ship Traffic Management • Cost-Benefit Analysis, Navigational Aid • Chart Update Analysis • Oil Spill Contingency Plan Studies • SAR/ SBV response time plots • Trend/ Sensitivity Analysis
