A CONTROL-SYSTEM FOR AN ULTRA-HIGH-SPEED BALLASTING EQUIPMENT

As the offshore installations associated with the production of oil grew in size so did the capacity of heavy lift equipment. In the Gulf of Mexico it was found that heavy lift cranes mounted on conventional flat bottom barges would perform at a tolerable workability rate. In the North Sea, on the other hand, the performance of these vessels became marginal at best. Some improvement was realized with the introduction of the heavy lift crane ships, but this was not sufficient to provide for an efficient year around operation offshore in these hostile waters. This fact led Heerema to design and have built two identical lift semi-submerisble crane vessels, the "Balder" and the "Hermod", both of which are now in operation.
