Twin City Shipyard Lays Keel

For Gulf Coast Trailing Dredge

Keel-laying ceremonies were held recently at Twin City Ship- yard in St. Paul, Minn., for the 3,850-cubic-foot, suction hopper dredge Ouachita being constructed for Gulf Coast Trailing Company of New Orleans. The 300-foot ves- sel will incorporate many state-of- the-art features unique for U.S. dredges, such as her propulsion and pump drive systems. The two main diesel engines will drive con- trollable-pitch propellers off their aft ends and a dredge pump and jet pump off the front of each engine through split gearboxes.

The deckhouse will be located for- ward for crew comfort and is de- signed to accommodate a crew of 26 in single and double staterooms.

Designed by Twin City, the dredge is scheduled for completion in the fourth quarter of 1985.

Twin City Shipyard has become one of the leading U.S. yards for dredge design and construction, along with its variety of split hop- per dump dredges and aluminum dredge tenders.

Gulf Coast Trailing is a joint venture between T.L. James, Inc. of Ruston, La.; Dredging Interna- tional N.V. of Belgium; and HAM

B.V. of the Netherlands.

Present at keel-laying ceremony were (L to R): G. Pieters, senior superintendent. Dredging
