Kody Marine Building For Maryland Marine Services
"The resurgence in the push boat new-builds for the petro-chemical market has been a pleasant surprise for Cummins Mid-South," says Calvin Klotz Vice-President for Marine Sales. Mid-South currently has engines for a half dozen or more Cummins-powered push-boats on order.
Three of these boats are building at Kody Marine for Higman Marine Services associated firm Maryland Marine Inc.. The first vessel, to be named Skipjack, will be delivered at the end of May. Construction on the two sister-ships is to start by July 1. Each of these three boats will be powered by a pair of Cummins KTA38 M1 main engines rated for 1000 HP each at 1800 RPM. The engines turn into Twin Disc MG540 gears with 6.18:1 ratios. The 78X53-inch propellers are mounted on 16-foot by 8-inch cold rolled shafts. Electrical needs are met by a pair of Cummins 6B5.9-powered 55 KW generator sets. Keel coolers for both the main and auxiliary engine are supplied by Fernstrum.
The 74 by 32-foot boats will have a molded depth of 10 feet nine inches and will operate with a normal draft of eight feet. The hulls will be framed with 5x3-inch 5/16th-inch angle iron with frames on 16-inch centres from the stern for 23 feet forward, then ten feet forward on 21-inch centres with the final 39 feet forward on 18-inch centres. Bottom plating is 5/8th and ½-inch plating. Sides and deck are 3/8-inch plate.
The four-level deck house on each boat will feature accommodations for up to seven crew in five cabins. Tankage includes 26,000 gallons of fuel, 16,000 gallons of water and 530 gallons each of lube and gear oil. Waste water will be handled by an Owens Model C wastewater system suitable for a crew of ten. The boats will be equipped with four flanking and two steering rudders all on eight-inch stocks. Each boat will have two Nabrico 40-ton, electric winches with 208 volt 3 phase power and controlled at the winch locations and in the wheelhouse.
Kody is also just completing the repower of the push boat M/V Cumberland with the removal of the old engines and installation of a pair of Cummins KTA38M0s and MG 540 6.18:1 gears. The job included the replacement of the exhaust, modification of grid cooler boxes and the installation of new grid coolers for the main engines and gear oil coolers.
