ESAB’s partnership with Canada’swest coast shipbuilding industry—Pacificat 1000 series high speed ferryby Willem Swint, Vancouver Shipyards Co Ltd, British Columbia, Canada.The Pacificat 1000 Series aluminium catamaran High Speed Ferry Projecthas allowed the Canadian west coast of North America to enter into a newera of aluminium shipbuilding.28 • Svetsaren nr 2 • 2000
This project was conceived by the Provincial Governmentof British Columbia with the construction of theferry modules starting in June 1996. The first of threevessels was launched from a floating dry dock (SeaspanCareen) at the Catamaran Ferry International’s northVancouver waterfront facility during the summer of1998. The third high speed ferry was launched in April2000, with delivery scheduled for August 2000.The unique way in which this ferry (122 metres inoverall length) was fabricated in a controlled environmentand then launched has prepared Vancouver ShipyardsCo. Ltd. for future challenges involving aluminiumfabrications of any size.The project has been managed since 1996 by CFI(Catamaran Ferries International), a wholly-ownedsubsidiary of B.C. Ferry Corporation (Crown Corporationof the B.C. Government). INCAT Designs of Sydney,Australia, and Robert Allan Ltd. of Vancouverwere chosen to design the Pacificat.Collaboration with Finnyards of FinlandFinnyards of Finland was used in collaboration for thetechnological transfer of aluminium shipbuilding methods,while using T.A.F.E. of Hobart Australia’s educationalinformation for tradespersons.The vessel was fabricated in five different westcoast locations, including Vancouver Shipyards, AlliedShipbuilders, Point Hope Shipyards, Ramsey MarineWorks and Alberni Engineering. The modules werethen transported by various means to the CFI facility innorth Vancouver, B.C., for assembly by some of theabove-mentioned consortium groups, as well as a sixthcompany, A & F Aluminum Catamarans Ltd.The first of the three Pacificat 1000 equipped withfour MTU diesel engines and Swedish-made Kamewawaterjets has been put through exhaustive sea trials,achieving a 37-knot service speed. The Pacificat’s interiordesign is the work of Figura Arkitekter, a Swedishcompany that has designed the interiors of several Europeanfast ferries.The hull portion of the vessel was fabricated usingPechiney Rhenalu 5383-H321 plate (thickness rangingfrom 6-25 mm), while the extrusion materials are 6082-T6 and 6061-T6 alloys. The 5083 alloy is utilised in otherareas throughout the vessel, with thickness of as littleas 2.5 mm. The lower vehicle deck panels were prefabricatedin Sweden using SAPA 6082 extrusion profiles.Inspections of the Pacificats have been conductedby one of the world’s leading classification societies forhigh speed vessels, DET NORSKE VERITAS, whichhas stated that these vessels meet all its requirements.More than 300 full-time weldersWith more than 300 full-time DNV certified weldersworking on the Pacificat project, the majority employedby Vancouver Shipyards, the company has demonstratedthat it is able to meet world standards when it comesto the quality of welding aluminium.As the project continues,Vancouver Shipyards X-ray acceptance rateSvetsaren nr 2 • 2000 • 29
