Big Towing/Supply Vessel Launched At Moss Point Marine

Moss Point Marine, Inc. of Escatawpa, Miss., recently launched a big towing/supply vessel for Intermarine of Houston. The vessel has an overall length of 218 feet, beam of 40 feet, and depth of 14 feet. It was named the Big Orange XXL "Intermarine needed a specialized vessel, so we 'stretched' our standard tug/supply boat design to meet its needs," said John Dane III, president of Moss Point.

Propulsion will be provided by twin GM Electro-Motive Diesel 12-645CE2 engines with a total output of 3,000 bhp at 900 rpm. These will drive Coolidge stainless steel propellers mounted in Kort nozzles via Falk 2.98:1 reduction gears. The main engines were supplied by George Engine Company. The propulsion package will also include a 600-hp Schottel bow thruster. The steering system is by E.M.I.

Electrical power will be supplied by a 125- kw Delco generator driven by a GM Detroit Diesel 8V71N engine. Electronics include a Furuno radar and Sperry autopilot. The Carrier air conditioning and heating systems were supplied by Marine Refrigeration. Kahlenberg supplied the air horns, Carlisle & Finch the searchlights, and Hubbell the running & navigation lights. Lifesaving gear is by Switlik and Zodiac. Accommodations will be provided for a 20-man crew.

Big Orange XXI has a clear deck area 146 feet long and 31 feet wide (4,526 square feet), and the following capacities: drill water, 228,700 gallons: liquid mud tanks, 1,352 barrels; bulk mud tanks, 11,824 cubic feet; fresh water tanks, 10,100 gallons; and fuel oil, 64,740 gallons. Equipped with a stern roller and double-drum winch, the vessel will be able to handle light towing and anchor-running duties.

Recent deliveries by Moss Point Marine include a 97-foot triple-screw tug and an 82-foot twin-screw line launch vessel for Nicor Marine of New Orleans, and a major repair project for Gulf Fleet Marine of New Orleans.
