Overview
Seaspan ULC, formerly known as Seaspan Marine Corporation and, before that, Washington Marine Group, is a Canadian marine-services company focused on the Pacific Northwest. Its activities span vessel construction, ship repair and maintenance, tug-and-barge transportation, ship docking and escort, commercial ferry services, and marine fuel supply. The company is part of The Washington Companies, the privately held industrial group associated with Montana businessman Dennis Washington. The modern Seaspan organization emerged from the 1970 combination of Vancouver Tug Boat Company and Island Tug & Barge. Those predecessor businesses brought together long-established coastal towing, shipyard, and marine-logistics operations. Vancouver Tug had roots reaching back to the late nineteenth century and owned a shipyard, while Island Tug & Barge had been established in 1924. Through later acquisitions, Seaspan added Gulf of Georgia Towing, F. M. Yorke & Sons, Kingcome Navigation, Coastal Marine Operations, and other assets connected with coastal transportation and ship repair. Seaspan's transportation activities support forestry, mining, construction, energy, infrastructure, and coastal-community supply chains. Its tug and barge fleet has carried logs, wood chips, hog fuel, lumber, pulp, paper, newsprint, aggregates, limestone, railcars, machinery, fuel, and general supplies. The group also provides ship-docking and vessel-assistance services at ports including Vancouver, Victoria, Esquimalt, and other British Columbia locations. Its ferry division, Seaspan Ferries Corporation, operates scheduled roll-on/roll-off services linking the Lower Mainland with Vancouver Island. These services transport trucks, trailers, containers, and railcars, including rail equipment connecting mainland networks with the Southern Railway of Vancouver Island. Shipbuilding and repair are central to the group. Its principal facilities include Vancouver Shipyards, Victoria Shipyards, and Vancouver Drydock. Vancouver Shipyards designs, builds, converts, maintains, and repairs vessels, while Victoria Shipyards specializes in large-vessel repair and refit work at the Esquimalt Graving Dock. Vancouver Drydock operates floating drydocks serving commercial and government vessels. The shipyard businesses have worked on naval, coast-guard, ferry, research, tug, barge, and other specialized vessels. A major turning point came in 2011, when Seaspan won the non-combat package under Canada's National Shipbuilding Procurement Strategy. The award positioned Vancouver Shipyards as a major builder for the Canadian Coast Guard and Department of National Defence and led to substantial modernization of its North Vancouver facilities. Seaspan subsequently became involved in the construction and support of federal vessels, including offshore fisheries science and research ships, an icebreaker project, and naval support vessels. Victoria Shipyards has also maintained and repaired Royal Canadian Navy frigates and submarines based on Canada's West Coast. The company operates through a portfolio of specialized marine businesses rather than as a consumer-facing product brand. Its identity is associated with dependable coastal transportation, industrial shipbuilding, naval and government-vessel support, ship repair, and port logistics. In addition to its core marine operations, the group has been associated with Marine Petrobulk, a bunker-fuel supplier serving ships calling at major British Columbia ports. Seaspan's current corporate structure and branding reflect the consolidation of several historic British Columbia marine enterprises under Washington-family ownership.
History
Seaspan ULC is the result of successive mergers, acquisitions, and reorganizations within British Columbia's coastal marine industry. One important predecessor was Vancouver Tug Boat Company, founded in 1898 by Harry A. Jones. The company developed into a major towing operator and also owned Vancouver Shipyards. Another predecessor, Island Tug & Barge, was established in 1924 by Harold Elworthy. In the late 1960s, Vancouver Tug was acquired by Dillingham Corporation, while Island Tug & Barge was acquired by Genstar. Dillingham and Genstar subsequently combined the two operations. In 1970 the merged business became Seaspan International Ltd. It expanded during the following decade through purchases including F. M. Yorke & Sons and Gulf of Georgia Towing. Marine Petrobulk was established in 1980 as a marine-fuelling business serving vessels calling at several British Columbia ports. Ownership changed again in the 1980s: Imasco acquired Genstar and later sold Seaspan to McLuan Capital Group. A separate but related strand of the corporate history began when Dennis Washington entered British Columbia's marine industry in 1992 through the purchase of C. H. Cates & Sons Towing and its Seaforth Towing subsidiary. Washington acquired Norsk Towing in 1995, Seaspan in 1996, and Kingcome Navigation in 1997. Kingcome had historic ties to coastal logging and pulp-and-paper transportation. In 1998 Washington acquired the rail and truck ferry operation of Coastal Marine Operations from Canadian Pacific Railway and renamed it Seaspan Coastal Intermodal. In 1999 the Seaspan, Cates, Seaforth, Norsk, and Kingcome operations were consolidated within Seaspan International, while Washington Marine Group was organized with separate divisions for towing, shipbuilding and repair, coastal intermodal services, and bunkering. The organization was renamed Seaspan Marine Corporation in 2011. At that time, shipbuilding, coastal ferry, and bunkering operations were organized as subsidiaries associated with the towing division. The legal and corporate identity later became Seaspan ULC. The shipyard side of the business also has a long history. Vancouver Shipyard was founded in 1902 in Vancouver's Coal Harbour and initially built fishing and pleasure boats. During the Second World War it constructed minesweepers for the Royal Canadian Navy. Vancouver Tug acquired the yard in 1954. Following the Dillingham acquisition, the shipyard moved to its present North Vancouver location, where it developed larger construction and fabrication capabilities. Seaspan later acquired assets connected with the former Versatile Pacific Shipyards. Seaspan and Allied Shipbuilders formed Vancouver Drydock Company to acquire floating drydocks and related facilities, with support from federal and provincial governments. Seaspan eventually acquired Allied's interest. Victoria Shipyards was established in 1994 at the Esquimalt Graving Dock after the collapse of Yarrows shipyard left a gap in the region's repair market. It grew into one of Canada's principal Pacific Coast ship-repair businesses, serving cruise ships, commercial vessels, and Royal Canadian Navy ships and submarines. The decisive modern expansion came through Canada's National Shipbuilding Procurement Strategy. Vancouver Shipyards was shortlisted in 2010 and selected in 2011 for the federal program's non-combat package. The award required extensive investment in facilities, equipment, workforce, and production systems. A modernization project began in 2012, followed by the arrival of a major gantry crane in 2014. The resulting platform supported construction and assembly of Coast Guard and defence vessels, including research and fisheries vessels, an icebreaker project, and naval support ships. Victoria Shipyards continued to provide major repair and life-extension services for naval vessels, including Halifax-class frigates and Victoria-class submarines. Today, Seaspan combines this shipyard capability with coastal transportation, ferry, ship-assist, drydock, and fuel-supply operations.
