Marinette Marine Lays Keel For

First Of 13 Yard Patrol Craft

Huge Drydock At Bethlehem's

New Sabine Yard Now Operational

Bethlehem Steel Corporation's new Sabine Yard in Port Arthur,

Texas went into service recently when its huge floating drydock was used to perform work on the 1st Lt.

Alex Bonnyman, a vessel for the

U.S. Navy's Maritime Preposition- ing Ship Program. The ship, one of two Maersk vessels reconstructed at

Bethlehem's nearby Beaumont

Yard, was scheduled for delivery in

September.

The drydock raised the ship out of the water to permit painting of the hull and installation of a new propeller. The drydock has a lifting capacity of 64,000 tons, making it one of the largest in the country.

Following a voyage from Hawaii earlier this year, the sections of the

U.S. Navy surplus drydock were berthed at the Beaumont Yard for modification and reactivation work.

The sections were then towed down- river to the Sabine Yard and assem- bled into the ship configuration used for the Bonnyman, which pro- vided a clear docking area of 829 by 122 feet.

For drydocking offshore drilling rigs, the sections can be arranged in two side-by-side batteries. This con- figuration will provide a clear dock- ing area of 413 by 362 feet.

Formal dedication ceremonies for the new Sabine Yard have been scheduled for the fall of this year.

Marinette Marine Corporation in

Marinette, Wise., recently laid the keel for the first of 13 Yard Patrol (YP) craft in advance of construc- tion schedule. Contracted by the

U.S. Navy, the vessels will be deliv- ered to the Naval Academy at Anna- polis, Md., and will be used for instruction of midshipmen in sea- manship, navigation, and marine engineering disciplines. The YP craft are wood hull construction with an aluminum superstructure.

Overall length is 108 feet, with a beam of 22 feet 9 inches and full- load draft of 5 feet 9 inches.

Marinette Marine was awarded the contract for six YP craft by the

Naval Sea Systems Command in

August 1984; a contract modifica- tion for seven additional vessels was awarded in December the same year. The contract also contains an option for construction of up to eight additional craft, subject to ap- proval of program funding for Fiscal

Year 1986. Delivery of the first YP is scheduled for August 1986, with the remaining vessels delivered one per month beginning in October that year.

The Wisconsin shipyard is a com- pany of marine design engineers and shipbuilders specializing in the de- sign and construction of defense- related marine vessels and high- technology commercial craft. 42 Maritime Reporter/Engineering News
