Investment in Design Big Power For Fast-Type Sulzer RTA60C: Wartsila NSD used the recent Nor- Shipping exhibition in Oslo as a launch- ing pad for its latest offering to the marine world, the Sulzer RTA60C, an engine designed for faster type ship requiring power outputs up to 18,880 kW (25,680 bhp). The RTA60C furthers the mandate to offer cleaner, more efficient power packages in a smaller space and less weight consuming manner. One indica- tion of its compact dimensions is the fact that the six-cylinder version is just 7,620 mm long. Length has been mini- mized in similar ways to those that have been proven a success in the RTA48T and RTA58T engines. The fact that the cylinder covers each have just four hold- ing-down studs further accounts for the compact arrangements, while simplify- ing manufacture. The RTA60C has a 600-mm bore and 2,250 mm stroke, and boasts a mcr of 2,360 kW/cylinder (3,210 bhp/cylinder) at 114 rpm. It is available with five to eight cylinders, covering the power Sulzer RTA60C Marine Diesel Engine Data Bore 600 mm Stroke 2,250 mm Stroke/bore ratio 3.75 Power, R1 mcr 2,360 kW/cyl. 3,210 bhp/cyl.

This power and speed was designed for a wide range of "faster" ship applications, such as medium-sized containerships Ships (abt. 1,200 to 2,700 TEU), car carriers, RoRo vessels, reefers. Aside from its operational attributes, the new engine is an important plank in Wartsila NSD's platform in that it was designed with ease and economy of manufacture in mind. This involves an extensive cooperation with major licensees building Sulzer diesel engines and subcontractors as well. The engine maker incorporated many suggestions from shipowners and shipbuilders, with respect to installation and maintenance. Foam Filled Marine Fenders Marine Guard " The Ultimate Protector for Ships, Harbor Craft, Wharves & Piers. • Construction complies with United States Navy and Coast Guard Specifications. • Core consists of closed-cell, resilient, energy absorbing foam, covered with a protective, seamless polyurethane elastomer skin. Filament nylon tire cord reinforcement is continously wound in the skin for added strength and durability. Will not mark or scratch vessel hulls. • Constructed with integral swivel end fittings, internally connected with a heavy duty chain. • Easy to install with very little maintenance. • Light weight and extremely buoyant with a lower reaction force than either hard rubber or pneumatic fenders. (Almost 40% higher energy absorption than pneumatic fenders.) URETHANE PRODUCTS CORPORATION (800) 913-0062 17007 South Broadway, Gardena CA 90248, U.S.A.
