Nichols to build two new tugs for Kirby Offshore

The following is the text of a news release from Nichols Brothers Boat Builders:

(FREELAND, Wash.) — Nichols Brothers Boat Builders (NBBB) recently signed a construction security agreement with Kirby Offshore Marine LLC to build two new 120-by-35-by-19-foot twin-screw tugboats. These tugboats will be used for tow operations.

Each tugboat will be powered by two Caterpillar 3516C, 2,447 bhp at 1,600 rpm main engines with Reintjes reduction gears turning two Nautican fixed-pitched propellers with fixed nozzles. These vessels will also have two C7.1 Caterpillar generators for electrical service. Selected deck machinery includes one TESD-34 Markey tow winch, one CEW-60 Markey electric capstan, and one Smith Berger tow pin.

Keels will be laid for both vessels this fall with delivery of the first vessel scheduled for May 2017. The second vessel is scheduled for delivery in November 2017. NBBB is pleased to sign these vessels, as they are currently building two 10-khp ATBs for Kirby Offshore Marine. Jensen Maritime Consultants of Seattle will provide the ABS class and functional design for the tugboats. These tugboats will carry an ABS load line, compliant with the U.S. Coast Guard, as required at delivery.

Kirby Offshore Marine is the largest United States operator of coastal tank barges and towing vessels participating in the regional distribution of refined petroleum products, black oil and crude oil, as well as the distribution of petrochemicals between petroleum administration and defense districts.
