during docking operations. If the fairlead rollers are not maintained, the lack ofmaintenance causes failure of the syn- thetic mooring line. Fluoron developed a cover material, which can be applied over the fairlead rollers using a patented ap- plication procedure. Fluoron?s material is designed to reduce the maintenance timeand costs for scraping paint and rust andto eliminate the need of repainting thesurface of the rollers. But more impor- tantly, it is designed to increase the life cycle of the synthetic lines. Fluoron?s roll covers will help prevent fraying and breaking of synthetic mooring lines, re-ducing the chances of injury. Fluoron?s cover material has been applied to deck equipment on tugs and cruise lines re-sulting in the reduction of maintenancecosts and increasing the life cycle of syn- thetic mooring lines. HEAVY LIFTERS Working in conjunction with rope, syn- thetic and wire, is a vessel?s deck ma- chinery, and advances in this regards have been proceeding at breakneck speed. Rolls-Roycerecently won a $81.4m contract by Swire Pacific Off- shore to supply anchor handling systemsfor four offshore vessels, currently under construction in Singapore. The systems are developed for the safe handling of large anchors on deck, such as the tor- pedo anchors used in the deep water oil and gas fields off the coast of Brazil. Rolls-Royce will supply a complete deck machinery system to each of thefour vessels, which are being built at the ST Marine Singapore shipyard. At the heart of the system is a low-pressure hy- draulic winch for anchor handling andtowing, with a pulling capacity of 500 The equipment package includes anchorhandling cranes, an anchor recovery frame which enables safer and more effi- cient handling of large anchors, and a stern roller with environmentally friendly bearing technology. Markey Machinery earlier this yearintroduced its new line of Abandonment and Recovery (A&R) winches suited for oil field services such as maintenance, re- pair and decommissioning. Markey?s type DEPS-76AR is a single drum, di-rect-pull type winch with level wind de- signed to work 3,300m of 4.75 inch diameter wire rope. Redundant vector- motors developing 1,750 hp turn the drum through an induction hardened hel-ical transmission. AC-variable frequency drives produce retrieval speeds of 32 m/minute. Markey?s automatic render/re- cover controls tame peak loads while pulling in 450Tm over cable weight. NABRICO is a full line marine sup-plier of anchor winches, winches,hatches, doors, castings, and other spe-cialty products. NABRICO?s DF-AW- 1200-30-2/15H-AUX anchor winch has 25,000 lbs of line pull, line speed of 30fpm, cable capacity of 1200 ft. of 1.75-in. wire rope, chrome plated levelwind to help prevent corrosion, and 15-in. warp- ing heads on each side of the anchorwinch. The DF-AW-1200-30-2/15H- AUX is a hydraulic anchor winch with an auxiliary power source that could fully operate the winch if the hydraulic sys- tems would fail to operate. The auxiliary power source is fully integrated into the winch and is operated by engaging the clutch assembly and applying power to the electric gearmotor.
