C603 Avondale's 81,000-ton floating drydocking (above) used to reactivate the Iowa (BB 61) will also be used for work on the Wisconsin (BB 64). Avondale To Perform Major Work On The Wisconsin (BB 64) Avondale Shipyards Division of New Orleans, under subcontract from Ingalls Shipbuilding Division, will perform the major work that is required in the drydocking of the battleship Wisconsin (BB 64), in- cluding the pumping out, gas freez- ing, repairing, and all of the coating of the ship's fuel and water tanks, replacement of propellers, inspec- tion and repair of the shafts and rudders, and the inspection and re- pair of the sea chests and sea valves. In addition, the entire exterior of the ship's hull will be recoated. The Wisconsin will be docked in Avondale's 81,000-ton floating dry- dock using the techniques that were previously used to dock the battle- ship Iowa, which safeguard the ves- sel from fire and other dangers involved in this type of work. At its peak, the work will provide employment for about 1,150 work- ers. When Avondale completes its work at the end of this year, the Wisconsin will then be towed to Ingalls in Pascagoula, Miss., for the remainder of its reactivation work. Avondale's reactivation work adds to its backlog of six T-AO 187 Class Fleet Oilers and five LSD-41 Class Landing Ship Docks.

With a bore of 260 mm and stroke of 980 mm, the new model in the ultra-long-stroke S-MC Series will offer outputs of 950 to 3,970 bhp from 4- to 8-cylinder in-line units capable of burning poor quality heavy fuel having a viscosity of up to 700 cSt at 50° C. During the design stage, special attention was paid to all details, dimensions, and weight. This has resulted in an extremely compact installation offering a highly attrac- tive, easy to maintain alternative to traditional four-stroke engine pro- pulsion plants.

The S26MC will deliver an output per cylinder up to 495 bhp at 250 rpm on a mean effective pressure of 16.8 bar. The S26MCE has a rating of up to 395 bhp per cylinder at the same speed, but on a mep of 13.4 bar. The large layout area offers flexi- bility with ratings down to 237 bhp per cylinder at 188 rpm. Specific fuel consumption at maximum con- tinuous rating ranges from 124 to 126 grams per bhp hour for the MCE versions and 126 to 130 g/ bhph for the MC version, with mini- mum part-load returns of 123-125 g/ bhph and 125-129 g/bhph, respec- tively. The S26MC is introduced as a logical development of MAN B&W Diesel's successful L35MC Series, until now the smallest-bore model of its kind in the low-speed, uniflow- scavenged, two-stroke engine sector. The 350-mm bore design made a swift and enduring impact from its introduction in 1981, winning nu- merous references within the pro- pulsion market traditionally con- fined to geared medium, four-stroke engines and Japanese low-speed, trunk piston machinery. Excellent service experience is re- ported from L35MC installations in small general cargo ships, tankers, reefers, chemical carriers, colliers, feeder containerships, and large trawlers. Operational benefits at- tracted the specification of a twin 9-cylinder L35MC propulsion plant for the Moroccan car/passenger fer- ry Marrakech recently delivered by Alsthom's St. Nazaire yard, and 7- cylinder engines for small LPG car- riers being built in West Germany for Brazilian owners. The S26MC aims to strengthen MAN B&W Diesel's hold on this important sector of the internation- al market and allow operators of medium and small ship types— oceangoing, coastal, and inland—to exploit the commercial and techni- cal benefits of the low-speed cross- head engine. Full support from design engi- neers with vast experience in de- signing engine room layouts and complete propulsion systems is available to operators and shipyards from the MAN B&W Diesel organi- zation, and may assist in layouts, specifying and/or supplying related equipment packages, and smooth- ing installation procedures. The package can be tailored to the indi- vidual project and embrace pump- ing, cooling, and fuel treatment modules, propellers, shafting stern tubes, alarm systems, and instru- mentation. Electrical power may be supplied via a power takeoff for a standard engine-driven generator. As an example of compactness, the 4-cylinder model will have an overall length of just over 3 meters, a height from the crankshaft center line of 4 meters, a minimum over- haul height requirement of only 4.4 meters, and a dry weight of 27 tons.
