Concept
Park ship
Résumé
Park ships were merchant steamships constructed for Canada’s Merchant Navy during the Second World War. Park ships and Fort ships (built in Canada for operation by the British) were the Canadian equivalent of the American Liberty ships. All three shared a similar design by J.L. Thompson and Sons of Sunderland, England. Fort ships had a triple expansion steam engine and a single screw propeller. Fort ships were ships transferred to the British government and the Park ships were those employed by the Canadian government, both had the similar design. Park ships were named after local and National Parks of Canada. A few Park ships were launched as "Camp ships", named after Canada military camps, but were quickly renamed after Parks. was the first Park ship lost to enemy attack, in the Indian Ocean after a torpedo attack from U-177 in the Indian Ocean, South of Durban, South Africa.
The Allied merchant fleet suffered significant losses in the early years of the Battle of the Atlantic as a result of U-boat attacks. The Park Steamship Company was created by the Canadian government on April 8, 1942 to oversee construction of a merchant fleet to help replace the lost vessels and to administer the movement of materiel. This was part of a coordinated Allied effort that saw the construction of British, American and Canadian merchant ships using a common class of vessel known as the North Sands class (named after a beach near the J. L Thompson yard on the River Wear).
Over the next three years, the company ordered approximately 160 bulk cargo ships and 20 tankers that would all fly the Canadian flag. Ships at 10,000 tons deadweight were known as Park class. 43 smaller vessels, at a nominal 4,700 tons, were at first designated Grey class but were later called Park ships as well and were commonly known as the 4700 tonner Park ships. All the Park ships were powered by coal driven steam engines. All but two vessels launched were named for federal, provincial or municipal parks in Canada. Some were armed with bow guns and anti-torpedo nets.
