Scale: unknown. One would be forgiven for thinking that this was the forward half of a much larger model. In 1972, a 20-year-old vessel, ‘Veedol’ was cut in half and the stern section converted to a bulk oil carrier. Its old bow was towed to Rotterdam and used as the basis for a new vessel, ‘Thor’ (1974), a diving support derrick pontoon for operation in the North Sea. It was fitted out with, among other things, a diving bell, compression chambers, and pile-driving hammers.

The model illustrates the more obvious changes to ‘Veedol’s’ old hull such as the crane itself, at the stern, and a new superstructure surmounted by a helicopter platform, at the bow end to act as a counterbalance. Between these features a large expanse of uninterrupted deck space was used for the stowage of cargo and equipment. We can also see ‘Thor’s’ eight large mooring anchors, exhaust vents, communications mast, and helicopter.
