Propulsion Technology MAN B&W Diesel Debuts the New S65ME-C MAN B&W Diesel designed a tailor- made S65ME-C engine for the latest design of Capesize modern bulk carri- ers. The engine was designed to respond to present and future bulk carrier needs, and it will fit into Suezmax tankers, as well. "We examined the market and received advice from Universal Shipbuilding Corporation in Japan, that there is an increasing need for more ded- icated engines for the specialized requirements of more and more refined ship designs," said Ole Gr0ne, two- stroke Vice President, Sales and Marketing, MAN B&W Diesel A/S. MAN B&W is positioning the S65ME- C as the solution for owners and opera- tors of modern large bulk carriers and Suezmax tankers, as well as large twinengine dieselized LNG carriers. The engine presents a 7-cylinder alternative to the 6S70MC and 6S70MC-C/ME-C engines. The reference list for the ME engine range now comprises 75 engines in nearly all available engine sizes, and service experience continues to be excellent.

Built by VT Halter Marine Oscar Dyson is designed to play a vital role in maintaining the health of the northern Pacific fishing industry. The ship will use a variety of techniques — including hydroaccoustic surveying — to collect the essential data required to establish accurate quotas. A ship measuring 210 x 49 x 28 ft. (64 x 15 x 8.5m) would nor- mally generate enough background noise to hinder surveying ops. Therefore, achieving a low acoustic sig- nature was a critical design parameter right from the start. According to the SCHAT vessel specifications, the stern tube bearing needed to be "of environmental- ly safe and acoustically inefficient mate- rials." In addition to being acoustically stealthy, Oscar Dyson is also equipped with DPS. The DP coordinates the thrusters and main shaft to effect the sta- tion keeping duty and hold the vessel in one position. Starts, stops and low shaft speeds are necessary to maintain the vessel at a precise geographical coordi- nate. When a ship operates in this man- ner, shaft squeal is the noise generated when the shaft is operated at slow speeds and is literally trying to stick to HARDING We can handle all your service needs worldwide First in Marine Evacuation Systems • Nine Locations Worldwide • Lifeboat Systems • Freefall Lifeboats • Cruise Tenders • Davits and Winches • After Sales and Service • Spare Parts NEW S0LAS/USCG APPROVED 4.5M RESCUE BOAT Circle 264 on Reader Service Card Worldwide spare parts deliveries for the ship department 'X T fc on time B •I, #MOTOR-SERVICE AB Stationsvagen 4 • SE-144 61 Ronninge • Sweden Phn: +46 8 532 535 42, +46 8 532 551 40 • Fax: +46 8 532 544 51 www.motorservice.se • sales@motorservice.se Circle 271 on Reader Service Card Smart Electronic Level Switch with No Moving Parts The Sea Switch Two was designed and patented for all tank applications. The Sea Switch Two offers a reliable solution for liquid level detection and control for cargo, ballast, and storage tanks, without any moving parts. The Sea Switch Two uses a fully static system that is based on the propagation of an acoustic wave into a metallic rod. A piezo-electric sensing element produces a wave along the rod. As the liquid reaches the sensing element the oscilla- tion stops and the alarm is activated. The Sea Switch Two sensor detects high, high- high, or low level in any liquid with an alarm output given by a dry contact or current loop change 6-18 mA. * Easy installation • Self-test built-in • Fully static system - no moving parts ^ Call today for more information!
