The DPII equipped ships also have two bow thrusters. Two of the three main engines are fitted with front-end power-take-offs and pumps to supply FiFi monitors mounted on the cabin tops. Guido Perla and Associates of Seattle provided the design and regula- tory package for the Bureau Veritas classed vessels, and also provided engi- neering support to the shipyard through- out the construction. The propulsion packages are a further example of inter- national cooperation and teamwork in building boats with this level of sophis- tication. Calvin Klotz, vice-president of the marine division of Cummins Mid- South in Kenner Louisiana, worked with Cummins China and Cummins Marine to broker the program with the shipyard and Group Bourbon. The engines and generators are being upfitted at the Cummins Mid-South facility in Louisiana and then shipped to China. Project Manager for Cummins Mid- South, Jack Bingert and Jim Wakenell of Cummins Marine have traveled to the shipyard several times to work in coop- eration with Gu Daming and Lin Song of Cummins China on the installation and commissioning of the power pack- ages. Circle 3 on Reader Service Card MAN B&W Power for Fratelli Neri MAN B&W Diesel A/S, Denmark, won a contract to supply a twin L21/31 propulsion engine package for a 98 ft. (30 m) Italian tractor tug. The order is significant in that it is this unit's debut in a tractor tug application, after a total sale of 280 units, with the majority dedicated to GenSet applications and propulsion of coastal tankers and general cargo ves- sels. The tug construction has started at the Italian shipyard Rosetti Marino SpA, Ravenna, for the Livorno-based Neri Group. Fratelli Neri SpA, owns and operates a large fleet of various tugs, supply vessels, floating cranes and barges, from various locations along the Italian east coast. The propulsion engines will be delivered from Denmark for installation at the yard during the month of August. The finalized tractor tug is scheduled to be delivered to the owner around the end of the year. Each nine-cylinder L21/31 engine is specified to an MCR rating of 2025 kW, and will drive a Schottel controllable pitch (SRP) rudder propeller unit. Additionally, the engines will each power an Advance/Asug gearbox, driv- ing hydraulics and firefighting pumps, via a front-end PTO. Circle 4 on Reader Service Card Contract for PSV Pair Bourbon Offshore Norway, a sub- sidiary of the French company Bourbon, signed a contract with Ulstein Verft for the construction of two Ulstein PX105s. These will be the first two platform sup- ply vessels (PSVs) in the world with the Ulstein X-Bow. "When we signed the contract for an Ulstein AX104 anchor handling vessel in April, it was because we had great faith in the new hull shape. The extremely good results from the model tests for the anchor handling ves- sel convinced us that the Ulstein X-Bow is the way ahead for offshore vessels. We think there is even more to be gained from a PSV with this new bow, as these types of vessels are continuously in traf- fic. They work in a shuttle system between land and the platforms and have to be reliable also in bad weather. The seaworthiness with the Ulstein X- Bow is so good that a vessel could be in operation even when the weather means other vessels have to stay in port. Fuel consumption is also reduced," says Bourbon Offshore Norway's managing director, Trond Myklebust, who recently succeeded Jostein Sætrenes. Ulstein Verft's sales manager, Harald Møller, confirms what Myklebust says about the Ulstein PX105's operational reliability, "Low angles of entry, no bulb, a con- verted bow and a hull that is drawn right up to the wheel house mean that there is no slamming or spray on deck. The good seaworthiness will make the vessel a fantastic place to work," he says.
