Bisso Towboat to build another tug at Main Iron Works

July 5, 2018 |


New Orleans-based Bisso Towboat Inc., has awarded a contract to boatbuilder Main Iron Works, Houma, La., to build a new 100′, 6,008-hp Tier 4-compliant ASD tractor tug. Construction is scheduled to begin later this summer, with a delivery in the fall of 2019.


“It will be very similar structurally and from a profile to our last newbuild, Liz Healy, as the vast majority of the changes will be in the engine room for the SCR system and larger Z-drives and a larger bow winch and bow staple to accommodate the increased horsepower/bollard pull,” Scott Slatten, Bisso’s president, said in an email.
