IMO compliant. The bridge equipment includes Furuno radar, AIS and GPS systems. A PC computer with printer also serves as a combined fax, telex,

GSM and e-mail messaging system uti- lizing the AmosConnect service.

The 105 x 32-ft. (32 x 9.76-m) boat has a 14.1 ft. (4.3-m) molded depth and a 3.5-m design draft. Accommodation is provided for 13 men. On her maiden voyage the 10-man crew, including

Capt. Abdul Raof Masse, were all

Indonesian nationals. Tankage is provid- ed for 278 cu. m. of fuel, 50 cu. m. of water and 43 cu. m. of fresh water bal- last. The 16-cylinder Cummins KTA50

M2 main engines each produce 1,600 hp turning at 1,800 rpm into Reintjes WAF 663 vertical offset marine gears with 5.95:1 ratios. This gives the 3,600 hp boat a bollard pull of about 42 tons and a 12-knot free running speed. A pair of 70 kW gensets meets the vessel's electri- cal needs. On deck, the tug is fitted with an 80-ton brake single-drum towing winch loaded with 600-m of 42 mm wire. A 35-ton towing hook is mounted aft of the winch.

Swiber Eagle sailed on a maiden voy- age on March 25 bound for Shanghai, where it picked up a new 250 x 90-m barge. She would then proceed south to carry pipe for phase II of a pipeline lay- ing project at Huizhou Island under con- tract to Global Marine.

Hatlapa Winches for Maria

S. Merian

One of the world's most modern research vessels - named Maria S.

Merian after the scientist born in 1647 - was delivered for scientific exploration on February 9, 2006. Maria S. Merian is to support the Polarstern as a floating laboratory during work in Arctic circles.

Polarstern was also equipped with

Hatlapa products. Seven special winch- es were supplied to the shipyard in

December 2003 already, which are also used for moving the underwater equip- ment. Hatlapa has escorted this project for five years, during which time the design of the winches was formed in close cooperation with the order princi- pal BAW (Bundesanstalt für Wasserbau) and the shipyard Krögerwerft in

Rendsburg. One speciality is the combi- nation of friction and storage winch for handling the very long and relatively thin measuring cables. The advantage is that the sensitive and expensive research ropes can be spooled on the storage winch free from load. The pull is created in the friction part and exerted via several grooved drums to protect the rope. A spooling device that has been developed and patented by Hatlapa also is designed so that the rope is wound onto the storage winch in a clean and gentle manner. Thereby the crossing of rope layers resulting in rope breakages are avoided. The storage winches have a very large drum diameter for realizing low bending radii of rope when wound on for protecting the sensitive measur- ing wires in the ropes. By using fre- quency inverter controlled motors the speed can be infinitely variably con- trolled and the winches operated syn- chronously. The electric driving capaci- ty of each winch is up to 352 kW, which is produced by four 88 kW motors kW.

To dissipate the heat arising in the elec- tric motors water cooling is provided.
