Golden Gate selects Mavrik Marine to build its new CARB-compliant ferries

La Conner, Wash.-based Mavrik Marine, Inc. reports that it has been selected to build a series of high-speed passenger ferries for San Francisco’s Golden Gate Bridge Highway & Transportation District.

The 50-meter aluminum catamaran ferries are being built as part of the district’s Liwa class replacement program and are designed designed to comply with California Air Resource Board (CARB) Tier 4 emission regulations

The specifications and systems were developed by Aurora Marine Design in San Diego with structural design from One2Three Naval Architects in Australia. Construction will begin immediately at Mavrik’s La Conner shipyard.

The vessels will provide fast, efficient, regulatory compliant passenger service across San Francisco Bay. The Golden gate District completes upwards of 20,000 trip crossings annually, resulting in approximately two million passenger trips.

The eight-vessel LIWA Ferry Replacement Program will update the district’s entire fleet over the next several years.

The new catamarans will carry 500 passengers, accommodate 75 bicycles, and include an ADA compliant elevator, snack bar, and indoor and outdoor seating for passenger comfort, all while cruising at speeds of 39 knots.

Powered by six MAN D2862 1066kW Tier 4 engines, the vessels will be outfitted with custom marine exhaust systems DPF/SCR exhaust filter modules.

Driveline Services of Portland carbon shafts connecting six Hamilton Jet HTX52 waterjets complete the propulsion system.

Traditional diesel generators are replaced by DanFoss gear driven generators, connected to Reintjes/Karl Senner hybrid gearboxes. Electrical storage will be provided by Echandia and McKay will provide electrical outfitting, alarm and monitoring package.

“Mavrik recently delivered four high-speed ferries to the Bay area, and we are very proud that our past performance and unwavering quality commitment allows us to partner with the district in the replacement of their eight-ferry fleet,” said Bailey Shewchuk, president of Mavrik. “The district specified several key components they wanted integrated into the vessel, all designed to maximize efficiency and improve maintainability. Our recent vessel deliveries were key in demonstrating our capabilities and every vessel we’ve built has been a great sales reference for us. The quality of a Mavrik vessel is unmatched and our entire organization is excited to showcase our experience on the Golden Gate project.”
