Silverback Marine, Tacoma, Wash., was recently awarded a multimillion-dollar DoD contract for its new OX series truckable tractor tug. Designed in collaboration with Elliot Bay Design Group, Seattle. Silverback Marine partnered with Darley Defense to secure the contract. The specific department of the DoD will remain anonymous until the first vessel is delivered, scheduled for late 2025.
“Silverback Marine is very honored to receive this contract, and our team is extremely excited to bring this innovative vessel to life in the coming months. Our exhaustive R&D efforts with a host of industry professionals has paid off, and the market was ready for fresh ideas and approaches,” the company said in a prepared statement.
For illustrative purposes, Silverback Marine received permission from Tradewinds Towing, Poseidon Barge, and Shaver Transportation to display the vessel in multiple livery schemes.
“The core purpose of this mini tug is to bring real, useable towing capacity to the truckable tug market. With the twin azimuth drives, captains can enjoy big tug characteristics in a very compact package, without the headache of costly Subchapter M requirements. The heavy-gauge aluminum hull, protected by Schuyler fendering, reduces weight and corrosion costs compared to traditional steel hulls, and the compact size allows haul out with conventional travel lifts,” Silverback said.
The company continued, “Especially when operated in multi-vessel teams, operators now enjoy the ability to perform operations normally only possible with much larger tugs. This nimble solution also reduces underwater noise and environmental impacts, making it an attractive choice for ports seeking grant funding opportunities and incentives.”
The vessel is powered by twinCummins diesel motors, Schottel Z Drives, withArcosa deck equipment and winches. Direct glazed windows, including a full height captain’s position centerline window, will offer a spacious, well-lit operators’ environment with unprecedented visibility, the statement noted.
The tug is also a candidate for hybrid and 100% electric propulsion, the company noted. Representatives from Silverback Marine and industry partner Photon Marine will be exhibiting and speaking at the upcoming International Workboat Show, where more information will be available.
