Transcript Fast Response Oil Spill Containment Vessel
Fast Response Oil Spill Containment Vessel
Lawren Best, Paal Jetlund Thorsager, Jen Alloway, Silas Spence
Background
Increase in tanker traffic in Hecate strait, current condensate shipping with expected oil export in the near future Tankers all the way up to Kitimat due to proposed new onshore LNG and crude oil terminals No dedicated oil spill equipment situated in the area, therefore a vessel is needed
Current Vessels
Burrard Clean No.8
49ft x 15ft Low endurance Low range 22knots max.
No skimming capacity 800hp Rozema Bay Class 48ft x 16ft Med endurance Med range 26knots max.
Integrated skimming 1320hp Kvichak Coastal Class 54 ft Low endurance Low range 30 knots max No skimming capacity No storage
Vessel Responsibilities
1) Arrive on scene quickly “An hour now can save a month later” 2) Deploy containment boom Consolidate oil so skimming can begin 3) Undertake small-scale skimming Clean-up small spills or provide auxiliary skimming capacity
Owner Requirements
Top speed of 30 knots, cruising speed of 28 knots.
Range of 300 nm at cruising speed, and an endurance on scene of 4 days.
LOA ~40-65 ft, beam 18~20 ft Capable of containing and recovering a 1000 litre spill Large working deck with space to store and deploy the boom.
What will our vessel do?
Skim and deploy boom Survive Sea State 6 Crew of 3-4 Hold a min. 1000 litres of spill oil
Hull form
Attended SNAME annual meeting in FL where USCG fast monohull tow tank data was presented 4 Models of varying L/B, β, Δ Provided a preliminary resistance estimate for different hulls through scaling for 60 ft vessel
