A new fleet of tugboats will be built to the latest environmental and US structural requirements for inland river operations.
Alabama-based shipbuilder Master Marine has secured orders for six tugs for operations on the Mississippi River. These will be built to Entech designs and the US Coast Guard’s Subchapter M requirements for structural and operational integrity.
They will be powered by twin Mitsubishi S6R engines with propulsion that meets IMO Tier III rules. According to BRL Shipping Consultants, the first two tugboats will work for St Louis-headquartered Osage Marine Services, while the latter four are for an undisclosed domestic owner.
Master Marine expects the first two vessels will be delivered and placed into service in Q2 and Q3 2019, while the other four will be delivered in Q4 2019 and in 2020.
Their Mitsubishi S6R main engines will be coupled to Twin Disc 5321 gears. Each tug will also have a pair of four-bladed stainless steel propellers supplied by Sound Propeller Services and two Northern Lights M65C13.2S electronic controlled generators that comply with IMO Tier III and RW Fernstrum keel coolers.
News of this six-tug order came in the same week as Foss Maritime confirmed it has ordered four tugs and holds options for another six for its port operations in the US west coast.
