Coastal Expands Presence After 10 years, Coastal Marine Equip-ment is a leader in the manufacturing of deck machinery for OPA 90 barges, OSVs, PSVs, ATB tugs and government vessels all delivered throughout the world successfully operating in some of theharshest environments. CME offers a complete line of marine deck equipmentincluding anchor windlasses, capstans,towing winches, mooring winches, an- chor winches, reels, spud winches, sternrollers, tow pins and rescue boat davits. CME?s 30,000 sq. ft. manufacturing fa- cility and 5,000 sq. ft. office is located on eleven acres in Gulfport, Miss., in the center of the Gulf of Mexico and boat building region. Each step in the manu- facturing of CME?s equipment is per- formed in-house including engineering,purchasing, quality control, safety, weld- ing, CNC and manual machining, surface preparation, assembly and testing. www.coastalmarineequipment.com Appleton Marine DeckEquipmentAppleton Marine is not only a manu-facturer of cranes, but a turnkey supplier of all types of handling equipment in-cluding winches, A-frames, anchor wind- lasses, capstans, and hydraulic power units. Current projects include packagesfor NOAA, the U.S. Navy, and various offshore oil installations. All equipment is proudly manufactured in the U.S.A.

Rapp technicians recently completed awinch drive retrofit for Otto Candies. An existing Rapp hydraulic winch was con- verted to electric, making use of Rapp?s Active Heave Compensation (AHC) package. ?Active Heave Compensation is important for our future vessel opera- tions in Brazilian waters, and the Rapp package has shown well with other cus- tomers,? said Brant Folse, Project Man- ager and Marine Engineer at OttoCandies. The Rapp design features liquid cool-ing?despite the fact that the R&D team at the outset considered myriad air- cooled designs before opting for liquid-cooling. The Rapp motor is designed to provide more kW per kilogram of weight than comparable air-cooled designs. Owing to favorable acknowledgement in the industry, Rapp patented the design. The motors are mounted on Rapp?s own in-house manufactured gearbox, that it developed long ago for its hydraulic winch lines. www.rappmarine.com TTS Marine Division Wins Electric Winch Contract Through its subsidiary TTS Marine GmbH in Bremen, TTS Group ASA has signed a contract worth approximately $4.5m. The contract with Hyundai Heavy Industries in South Korea con- cerns delivery of electric-driven winch systems for 4 container carriers for a Ger- man owner. The delivery will take place within 2013 ? 2014.Vestdavit Supplies Extra-Long Outreach Seismic DavitsNorway-based boat handling system and specialized davit supplier Vestdavit has been contracted by Mitsubishi Heavy Industry on behalf of Petroleum Geo-Ser- vices (PGS) to design and supply extra- long outreach workboat/lifeboat/FRC davits for PGS?s 5th generation Ramform new building seismic vessels. The two davits for each of the two vessels building at Mitsubishi Heavy Industry, Japan for 2013 delivery will have an extra-long outswing to be capable of launching andrecovering 20 man tender boats safely in seas states 5 ? 6. Vestdavit has designed a special Vestdavit H ? 10000S dual point hydraulic davit with a dual winch system for the application. Atle Kalve, develop- ment manager, Vestdavit, says, ?These davits will make deployment and re- trieval safer for PGS? crews. The tender boats will normally be used in relatively calm sea states, but are constructed to handle safely even in sea state 6, and these davits will recover them safely in those seas.? The boats and davits also have the func- tion as lifeboats and Fast Rescue Craft in an emergency. A key benefit of these davits is the simplicity of use, which re- duces crew training needs. Rapp Hydema, founded in 1907, is a world leader in provision of deck machinery, with winch manufacture that goes back nearly five decades. New for Workboat 2011: we have just acquired Hydra Pro Seattle--which adds crane and other deck machinery manufacture--under the single Rapp roof. Core Workboat prod- ucts include single and double-drum Towing, Mooring and Anchor winches, windlasses and capstans on the one hand, and Deck, Offshore, Subsea and Cargo Rail Cranes on the other.

This implementation is MTNW?s first use of tension measurement technology with 2?+ synthetic ropes. Recently, Delmar Systems was contracted to moor an offshore supply vessel (OSV) to a major offshore platform in the Gulf of Mex- ico. The OSV is being used as a support ves- sel while dive operations are conducted. The OSV is using a three-point mooring systemconsisting of two stern hawser lines attached to the platform and a bow mooring line at- tached to a preset suction pile foundation in2,900 feet of water. The mooring system had to be as robust as possible while still main- taining ease of handling and rigging by the vessel crew. To achieve a higher Maximum Breaking Load on the OSV bow mooring line while maintaining deck maneuverability, Delmar chose Samson?s AmSteel-Blue HMPE rope made of high modulus polypropylene (HMPE) as the bow winch line. An MTNW RL-20175K running line tensiometer provided tension measurement for the bow line. During the design phase of the project, MTNW thoroughly tested and calibrated the RLT using the specified 2¼" AmSteel-Blue rope. ?This is MTNWs first use of an RLT to measure tension in a major synthetic mooring line of this large diameter,? said Tom Rezanka, managing director of MTNW. ?Our RLTs are more commonly used to measure the tension of wire rope, but synthetic lines have different mechanical characteristics under load. We were able to collaborate closely with the R&D engineers at Samson. The moni- toring system was fully tested, calibrated and witnessed on an ABS-certified test bed with the resulting accuracy identical to wire rope applications.? 104Maritime Reporter & Engineering News MR Nov.11 # 13 (98-104):MR Template 11/4/2011 1:58 PM Page 104
