Deck Machinery Ana Cargo-Handling Equipment —A Review— models ranging in capacity from 50,000 to 660,000 pounds line pull. These diesel-driven units are avail- able in waterfall or side-by-side double-drum configuration. Special-application cranes and winches are also available to meet the requirements where off-the- shelf equipment will not do the job. Appleton Marine is a division of Wartsila-Appleton, Inc. located in Appleton, Wise. the winch. All models are either ful- ly type-approved or currently under review by the American Bureau of Shipping, Det norske Veritas, and Lloyd's Register of Shipping for general utility and Man-Rider® ser- vice. Beebe sales and service are avail- able worldwide. BLUE STREAK With current daily operating costs totaling many thousands of dollars, ships must keep port time to a minimum for cost-efficient op- erations. Therefore, reliable and ef- ficient cargo-handling gear, deck machinery, access equipment, and stowage systems are essential for a fast turnaround. MR/EN asked the manufacturers and distributors of this type of shipboard and shoreside equip- ment to tell us about their latest developments. The review that fol- lows is based upon the responses we had received at press time. Free literature describing all of the equipment featured in this re- view is available from the manufac- turers.

APPLETON MARINE Circle 10 on Reader Service Card Appleton Marine cranes have been specified for use on 16 high- speed patrol boats for the U.S. Coast Guard currently under con- struction at Bollinger Shipyard in Lockport, La. These telescoping- boom units have a capacity of 1,750 pounds at a maximum working ra- dius of 18 feet, and feature a 7-foot boom extension. These cranes also feature an oper- ational capability with full load at 15-degree list while maintaining a 6:1 structural safety factor. Other features include dual electrohy- draulic controls (local and remote), stainless steel cylinder rods, 50-fpm winch line speed, combination steel/ aluminum construction for maxi- mum weight savings, and an electro- hydraulic power unit with an axial piston pump for low heat build-up. An articulated-boom crane rated 4,900 pounds capacity at 25-foot working radius is being installed on all 10 Torpedo Weapons Retrievers being built for the U.S. Navy at Marinette Marine in Marinette, Wise. A full line of API/ABS rated cranes in telescoping or box boom configurations ranging from 4 to 100 tons capacity is available. All Apple- ton cranes feature 360-degree con- tinuous-swing rotation, stainless steel fasteners, exposed valve spools of stainless steel, and a four-step inorganic zinc based marine coating system. A wide variety of options is also offered. Appleton's towing and anchor- handling winch line features 10 ASEA Circle 11 on Reader Service Card ASEA, Inc. of White Plains, N.Y., markets it Optitrim system that is designed to help plan cargo loading, fuel oil and freshwater bunkering, and the correct positioning of bal- last in order to obtain maximum fuel savings. The company reports that this system will increase oper- ating efficiency substantially, re- duce costs, and pay for itself in less than a year. The Optitrim indicates the most efficient mode of operation at every speed and load condition, showing basic optimum and actual figures. It can calculate cargo in each hold in percent, volume, or weight. The unit provides optimum trim calculations when the estimated average speed is used as input. It then calculates the optimum trim for the mean draft and presents the optimum fuel sav- ings in tons per day when the ship is retrimmed to its optimum. The operator can shift cargo from one hold to another and immediate- ly read off the differences in fuel savings by doing so. Every factor that affects the trim is taken into consideration. BEEBE Circle 12 on Reader Service Card Beebe International, Inc. of Seat- tle recently introduced three new capacities to its Force-5® Series of air winches that were originally in- troduced in 1985. The new V2-, 1-, and 10-ton winches, along with the original FA2, 5, and 7, now bring a full range of capacities to the indus- try. Said to be the only all-steel win- ches suitable for worldwide use in temperatures as low as -30° C with- out modification, these new Beebe units are rated full drum with a 5:1 safety factor that provides assur- ance of continuous duty and power regardless of layer. The Force-5 Series air winches are capable of precise load spotting through an optional oil bath disc brake that lasts virtually the life of Circle 14 on Reader Service Card A line of lightweight marine cranes said to offer heavier lift ca- pacity, increased reliability, reduced maintenance, greater safety, longer component life, and smoother oper- ation is available from Blue Streak Industries of Pearlington, Miss. These pedestal-mounted, lattice- boom cranes are designed for use on offshore rigs and platforms, work- boats, and ships. The series includes units with lift capacities from 25 to 100 tons. The improved capabilities are at- tributed to the use of computer- aided design, a closed-loop hydrau- lic system, and the use of the high- est quality components and equip- ment. Closed-loop systems employ a continuous hydraulic loop from pump to motor to pump, which pro- vides precise control similar to that provided by diesel-electric systems. Prior to now, continuous-loop hy- draulic systems were not in general use on cranes because of higher ini- tial costs and purported greater maintenance expense. Blue Streak's experience in building and operat- ing a large fleet of self-elevating lift- boats utilizing both open- and closed-loop systems indicated that the latter could improve perform- ance while reducing overall mainte- nance costs. The company's engi- neers overcame the higher costs by developing an improved oil filtra- tion system that effectively removes contaminates from the lines, thus reducing maintenance and lost reve- nue due to vessel downtime. After the closed-loop system had proven itself on self-elevating rigs weighing up to 325 tons, it was adapted for use on Blue Streak's latest cranes. The first production model, a 75-ton-capacity crane, has been working flawlessly on the Gulf Island V, one of the world's largest liftboats, since early last year. While perfecting the closed-loop system, Blue Streak's engineers ex- tended the service life of their cranes by using components not normally found on cranes of this type. Superior quality components such as Hagglunds high-torque, low- speed motors, Rexroth pumps, and EEM controls are used. All units are designed and built for the corrosive offshore environment. They are pro- tected from salt water by the use of galvenized metals, waterproof fit- tings, and marine coatings. Blue Streak provides 24-hour ser- vice by the same technicians who build the cranes. BRADEN Circle 15 on Reader Service Card Braden Cargo Gearmatic, winch divisions of PACCAR, a major supplier of performance-proven winches to the offshore and marine crane industry, have introduced two winches in their PD (Power Drum) series of hydraulic planetary winches. The PD7A and PD12C (7,500 and 12,000 pounds rated capacity, re- spectively) feature highly efficient, computer-aided designed gear sets supported on anti-friction bearings that run in oil to minimize frictional losses and reduce downtime. Load control, when lowering, is main- tained by the patented Braden brake valve known for its smooth performance and easy adaption to almost any hydraulic system. This brake valve is backed up by an internal, automatic multi-disc spring applied/hydraulically re- leased safety brake. An over-run- ning brake clutch permits free rota- tion through the brake while hoist- ing, but immediately locks when the hoisting operation is complete. The load is held firm even if the engine dies or a hydraulic line breaks. Maximized commonality of parts in the PD Series winches, along with the PR Series swing drives, results in lower parts inventories to support marine crane service. JERED BROWN Circle 16 on Reader Service Card Jered Brown Brothers is a major supplier of deck machinery and oth- er marine equipment worldwide. Products include anchor windlasses and capstans, non-magnetic mine- sweeper deck machinery, cranes, steering gears, elevator systems, main thrust bearings, and line shaft bearings. Jered equipment is speci- fied on FFG 7, CG 47, LSD 41, LHD 1, MCM 1, T-AO 187, T-5, and CVN Class vessels and many other com- mercial ships. In addition to providing equip- ment on new ship construction, Jered provides spare parts and maintenance on deck machinery in service. Jered has engineering draw- ings and parts for equipment manu- factured by American Engineering. 22 Maritime Reporter/Engineering News
