Naval structure agency Glosten and ABB have joined forces to develop a methanol-hybrid ship help tug design that gives operators with a viable path to carbon-neutral operations whereas minimizing working prices.
Referred to because the SA-100, the 100-foot ASD harbor tug is propelled by two methanol- suitable CAT 3512E gensets powering electrically pushed L-drives. The gensets are complemented by battery banks for zero-emission operation when transiting, peak shaving throughout normal operation, and as increase for attaining the tug’s peak bollard pull of 90 brief tons.
The SA-100 was additionally designed to measure below 100 gross registered tons.
“We had three primary design objectives in developing this tug—all intended to benefit the owner/operator,” mentioned Peter Soles of Glosten, who leads the conceptual growth of the agency’s tug designs. “First, to provide assurance of regulatory compliance and future adaptability; second, to achieve meaningful improvement in environmental performance; and lastly, to control OpEx costs such that assist services can still be offered at competitive rates.”
“Every tug operator is trying to determine their company’s path through this new hybrid and electric world. The SA-100 design is the perfect stepping off point for those that cannot leap headlong into all-electric propulsion. With this design, the operator will reap some of the instant power availability and operational savings of an electric vessel, without the need to ‘plug in’ at the dock. At the same time, it will allow them to realize a substantial reduction in EPA criteria emissions,” mentioned Dave Lee, VP of gross sales with international workboat accountability at ABB Marine & Ports.
