VIDEO: Australian company to debut hydraulic-suspension cat

2Play, Nauti-Craft’s new cutting-edge prototype hydraulic suspension catamaran, is set to debut June 10-12 at the Seawork International Commercial Marine and Exhibition Forum in Southampton, England.

Nauti-Craft Pty Ltd. is a small research and development company in western Australia that is focused on the design and development of the Nauti-Craft marine suspension system.

The 26-foot catamaran’s hydraulic system separates the hulls from the superstructure, allowing them to react rapidly to wave inputs and conform to the ocean’s surface without transmitting high forces to the deck and superstructure.

The “passive reactive” interlinked hydraulic system is a departure from conventional naval architecture. The interrelated hydraulic systems allow a greater amount of body and chassis control in big seas in both the roll-and-pitch axis and in the free warp, or articulation of the hulls. The design aims to provide increased levels of ride comfort, control and stability in stationary positions and while traveling at speed.

The hydraulic suspension system, combined with a Deck Attitude Control System, which actively adjusts and maintains the vertical attitude of the deck, help make crew transfers more manageable in rough seas. The Australian company’s design addresses reduced slamming and jarring motions, reduced pitch and roll and improved planing in rough seas. The design allows a smaller vessel to provide seakeeping typically found only in larger boats, reducing the operating costs, Nauti-Craft said.

Nauti-Craft’s marine suspension is one of 13 concepts selected from a field of more than 450 international entrants in the Carbon Trust’s Offshore Wind Accelerator competition. The design was selected as one that could greatly aid the safe transfer of engineers to offshore wind turbines.

“We’ve trawled the globe looking for revolutionary new ideas that can transfer engineers safely in the huge swells around the U.K.’s coasts,” said Benj Sykes, director of innovation at the Carbon Trust.

“People have been building boats for thousands of years, but we’ve seen some truly radical departures from what you would think a boat should look like. These designs could significantly improve the economics of offshore wind and keep our engineers safe far out to sea. Our analysis shows offshore wind is a huge green growth opportunity which could create up to 230,000 jobs in the U.K. by 2050.”
