International Dredging Review

International Dredging Review

At the end of August the new 58-foot survey boat Moritz was bound for its final destination in New York via the Panama Canal. It was unloaded in Fort Lauderdale Florida then piloted to New York by a crew from Kvichak Marine Industries.

The boat was shipped from Vancouver B.C. on a drydock ship that also carried a dozen yachts.

Boat operator Tim Lafontaine of the New York District Corps of Engineers met the crew in Florida and accompanied them on the trip north.

Built in Seattle by Kvichak Marine Industries Inc. the catamaran-type boat is outfitted with an extensive array of survey equipment including a Ross Dophin Mini-Sweep System and a Reson 8101 multibeam system with a transducer head in each hull.

Successfully completing sea trials in mid-May the vessel displaces 30 tons and can sustain speeds up to 30 knots.

“We were getting sounding from the hull transducers at 30 knots (during the sea trials)” said Jim Ross.

The Ross Mini-Sweep is a nine-channel system with individual transducers mounted on two 17-foot hydraulic booms and in the hull to provide a sweep wide of approximately 55 feet. The booms are stored in recessed areas in the hull leaving the deck clear at all times. They are deployed by an independent hydraulic system using controls at the helm station.

Electronics are stowed in two desktop cabinets one containing the depth sounding system and the other a data collection computer and DGPS sub-meter system. Coastal Oceanographics Hypack Max and Hysweep software are installed for data processing.

The vessel will be assigned to work out of the Caven Point New Jersey facility. New York District’s Civil Works mission includes navigation and water resource activities in the watershed areas of Lake Champlain the Hudson River New York and New Jersey western Vermont and small portions of Massachusetts and Connecticut.

The vessel was named in honor of Kurt Moritz who in 1977 retired from the Corps of Engineers after 27 years of service and died in 1988.
