McDermott Delivers Two

Caterpillar-Powered

Supply Vessels To Tidewater

McDermott Shipyard's New Iberia Division recently delivered two 194-foot supply vessels to Tidewater Marine Service, Inc., a subsidi- ary of Tidewater Inc. The Jan Tide and the

Abshire Tide are the seventh and eighth in a series of 10 supply boats being built by Mc-

Dermott for Tidewater. The previous six ves- sels were 180 feet long; however, a contract change called for the last four boats to be lengthened 14 feet. The final two are sched- uled for delivery during the first quarter of this year.

Jan Tide and Abshire Tide have a 40-foot beam, 14-foot molded depth, and design draft of about 12 feet. Each vessel admeasures less than 300 gross tons, and has below-deck stor- age capacity for 121,000 gallons of fuel oil, 11,000 gallons of potable water, 1,130 barrels of liquid mud or chemicals, and 4,000 cubic feet of bulk materials. Accommodations are provided for 23 personnel.

The new supply vessels are certified by the

American Bureau of Shipping and the U.S.

Coast Guard for service on any of the world's waters. They will be operated under the U.S. flag.

Twin Caterpillar D399 diesel engines power the vessels, generating a total of 2,250 bhp at 1,225 rpm. They are linked to Reintjes WAV 1440 reverse/reduction gears having a 4:1 ratio.
