I.T.C. Holland Engineers Its Third Double Rig Dry Transport On The Sibig Venture

I.T.C. Holland B.V., Haarlem, Holland, the Netherlands, recently contracted the dry transport of two Rowan rigs from Seward, Alaska to Port of Spain, Trinidad.

The Rowan Middletown was loaded aboard the Sibig Venture in Seward, Alaska. The vessel then proceeded to Long Beach, California where the Rowan Alaska was floated onboard.

The 15,000 mile voyage via the Strait of Magellan is projected to take about 50 days. The rigs, as well as the ship, are too large to transit the Panama Canal, which has a width restriction of 106 feet.

The rigs are owned and operated by Rowan Companies Inc., Houston, Texas. The Rowan Middletown is a Marathon LeTourneau 116-C design having 410 feet of legs installed and a total weight of 9,587 tons. The Rowan Alaska is a Marathon Le- Tourneau ML-84-S design having 410 feet of legs installed and a total weight of 9,200 tons.

The Sibig Venture is owned and operated by Tschudi & Eitzen (Oslo, Norway). The vessel, one of the largest of its kind in the world, has an overall length of 728 feet, width of 138 feet, with a clear deck length of 423 and clear width of 138 feet. The deadweight capacity is 44,000 tons.

Axel C. Eitzen, of Tschudi & Eitzen, shipowner of the Sibig Venture, as well as a fleet of OBO carriers, was present during loadoutoperations in Long Beach. (The Tschudi & Eitzen families marked the 100th anniversary of their partnership in 1984. Captain Henry Tschudi is the elder of the joint partnership.) Tschudi & Eitzen (Oslo) and I.T.C. Holland have been associated for many years, combining their respective talents as shipowners, marine engineers and naval architects.

Noble Denton & Associates of Houston, Texas, were the insurance surveyors assigned to the project.

I.T.C. (USA) Inc., is also located in Houston, and headed by Edward Punch, vice president.
