Welds !
Them weld lines are significant for this subject !
There were pioneering times for welding, the TIDS ( Technology In Developement ) were the first ships to be made in sections in seperate locations, the sections brought by rail to the assembly yards where they were joined.
Riveting was too slow, they had to put 'em out quickly as they were getting the crap bombed out of 'em every night in the cities.
History
Richard Dunston started building wooden barges, in 1858 on the bank of the Stainforth and Keadby Canal in Thorne, some 45 miles from the sea. He used locally- grown, hand-sawn timber.[1] In 1902, control of the yard passed to Thomas Dunston and, in 1910 to the 20 year old grandson of the founder. He set about modernising the business to enable the construction of iron and steel ships, but was limited by the size of vessel that could be built at the Thorne site on the canal.
Dunstons bought the Henry Scarr shipbuilding yard at Hessle in 1932, which allowed ships to be launched directly into the Humber.[2] They pioneered construction of all-welded ships in the UK, finding that they could mass produce a single design more efficiently than traditional riveting. During the war they built 159 all-welded steel tugs, the TID tug,[3] with one completed ship leaving the shipyard at six-day intervals.[1] Sections were fabricated for erection elsewhere.[4]
TID was a standardized British design for a tugboat drawn up and built during the Second World War.
The hulls were built as eight separate sections by a group of manufacturers with spare welding capacity - normal British boat construction being riveted - building capacity was in short supply at shipbuilders but other non-shipbuilding industry was available. These 6 ton sections were transported by road or rail to the shipbuilder for assembly and fitting out. Production was fast at about one hull every five days.
Henry Kaiser may have heard about this method of construction ...
