Waterfront Services Co has begun to renew its fleet of tugboats with the delivery of the first tug of a four newbuilding series. US shipbuilder Master Marine delivered 20 m tug Miss Deborah to the owner, which provides towing services in Illinois in the USA.
Master Marine is building four tugs, each with a pair of Laborde Products-supplied diesel marine engines that meet the US’s emissions standard Tier 3. These tugs will have Mitsubishi S6R2-Y3MPTAW engines that operate at 1,400 rpm, coupled with Twin Disc MG 5321 5:1 ratio gears and E300 electronic controls.
Electrical power for these tugboats will be provided by Laborde Products with two Northern Lights M65C13.2S electronic-controlled generators that are Tier 3 compliant and generate 65 kW of power.
Propulsion comes from a pair of four-blade stainless-steel propellers supplied by Sound Propeller Services and two J&S Machine Works propeller shafts with Thordon bearings, Thorplas bushings and shaft seals. Gulf Coast Air & Hydraulics Inc is supplying the steering system and a pair of Quincy F325 reciprocating air compressors.
Schuyler Maritime is providing rubber fendering around the entire perimeter of the vessels along with the push knees, with MMI-installed weld caps between all fenders. RS Price & Son supplies the Mitsubishi mini-split heat pump HVAC system on all interior spaces.
For the deck machinery, Dickson Marine Supply is supplying a pair of Wintech 40-tonne winches for each tug. The electronics and communications for the vessels is supplied by New World Inc.
All of the boats will be set up with 10,400 gallons of fuel, 4,359 gallons of potable water and 9,500 gallons of ballast water.
