News: SWATH Design Boasts Flexibility, Efficiency
Alan C. McClure Associates (ACMA) has completed the design development of a new SWATH (Small Waterplane Area, Twin Hull) vessel that the designer says lends itself to a variety of operation options. The proposed vessel will be 92 ft. long with a 46.6-ft. beam and a displacement of 240 LT. The new vessel's design is based on a variation of the technology used by ACMA's in the development of the 120-ft. Stillwater River, a SWATH crewboat built for Trico Marine Operators, Inc., that has been successfully operating for Petrobras offshore Brazil for the past five years. The operational speed of ACMA's new SWATH has been reduced from more than 28 knots to 20 - 25 knots to accommodate a variety of conventional propulsion system combinations (diesel/reduction-gear w/CP or FP wheels).
New SWATH Design Boasts Flexibility, Efficiency
Alan C. McClure Associates (ACMA), a leading naval architecture and engineering firm, recently completed the design development of a new SWATH (Small Waterplane Area, Twin Hull) vessel that lends itself to a variety of operations options. The proposed vessel will be 92 feet in length, with a beam of 46 feet - 8 inches and displacement of 240 LT. The new vessel's design is based on a variation of the technology used by ACMA's in the development of the 120-foot STILLWATER RIVER, a SWATH crewboat built for Trico Marine Operators, Inc., that has been successfully operating for Petrobras offshore Brazil for the past five years.

Weight Saving Features for Maritime Dynamics Ride Control System
With faster speeds and lighter hulls, ship builders and owners require lightweight equipment. Maritime Dynamics will be incorporating weigh saving features into its ride control system to address this challenge. The first measure has been to design the ride control hydraulics system to operate other onboard equipment. Maritime Dynamics offers hydraulic packs, which, in addition to the ride control system, operate the propulsion waterjet steering, and reversing system. During docking maneuvers, the power packs can operate car ramps, capstans and anchor winches. This summer, Maritime Dynamics will install its first commercial computer-based ride control system with an embedded Microsoft Windows operating system.
