Todd Announces Completion Of Derrick Barge Cherokee Arthur W. Stout Jr., general manager of Todd Shipyard's Houston Division, has an-nounced the completion of the 350-foot by 100-foot by 25-foot derrick barge Cherokee and its delivery to Santa Fe-Pomeroy Marine Serv-ices Company. Though originally planned as a 500/1,000-ton derrick barge, a pipe ramp was designed and built into the vessel at the direction of the owners to give it the added capability for use as a pipe laying barge. The vessel's revolving derrick will lift 500 tons as high as 150 feet at a radius of 95 feet, and in a fixed position will handle lifts up to 1,000 tons. The boom is 275 feet long and has, in addition to the heavy lift block, an auxiliary block of 150-ton capacity at a 130-foot radius, and a light load block of 50-tons capacity at a 240-foot radius. The vessel has air-conditioned living quar-ters for 133 workmen and a crew of three. Medium-Speed Diesels In Production at B&W At Burmeister & Wain's subsidiary com-pany, Alpha-Diesel A/S, Frederikshavn, Den-mark, a diesel engine of the new type, V23H, was demonstrated recently. This is a four-stroke V-type engine which has a rating of 122 bhp per cylinder at 800 rpm, and is built with from 8 to 18 cylinders. There are several reasons why Burmeister & Wain has commenced its production of four-stroke engine types. First of all, medium-speed four-stroke engines, because of their low weight and small space requirements, have in recent years won increasing popularity with shipown-ers for the propulsion of large and small ships ; the second reason is that with this type engine it is possible to cover a very much larger horse-power range than has been possible up to now with B&W-Alpha engines having a top rating of only 1,000 hp. Further, with the choice of the 23-type, a simplification of production, stocking, etc. has been achieved, since this type?both as in-line and V-type engine?has replaced two or three earlier engine types and is produced by B&W's Danish subsidiary com-pany, Holeby Dieselmotor Fabrik, and by sev-eral other licensees abroad. In geared marine installations, one or more engines can be coupled through a reduction gear to a controllable-pitch propeller, or through reduction and reversing gears to a propeller with fixed blades. Additionally, this engine can be applied to power generators in diesel-electric propulsion plant, as marine aux-iliary engines, as well as stationary plant. With multi-engine installations of the V23H-type, very high outputs can be obtained; for example, a plant with four 18-cylinder engines could have an output of approx. 10,000 bhp. Although the new V-type engine will find ap-plication as a propulsion engine in steel trawl-ers, smaller freighters, and all types of spe-cialized ships, there is also the possibility of covering the propulsion requirements for larger merchant vessels, ferries, roll-on/roll-off vessels, etc., where the low height of the V23H-engine is an advantage. The first two V23H engines built at Fred-erikshavn, are 12-cylinder units of 1,470 bhp, which are to be installed in tankers of 499 grt, building at Solvesborgs Varv in Sweden for two Swedish owners. Among the orders re-ceived are three 8-cylinder V-type engines for a Danish owner. To date, 120 engines (639 cyl-inders) of the 23-type have been delivered by Holeby Dieselmotor Fabrik and B&W's li-censees, and there are 265 engines (1,499 cyl-inders) on order.
