This vessel was conceived, constructed and will be operated entirely in house under the parent company; ICDAS Celik Enerji Tersane ve Ulasim A.S, in Turkey.
The Z-Tech™ 6500 is a unique Class of ship-handling tug designed to provide a combination of the superior handling characteristics of an ASD tug with that of a Z-drive tractor. This vessel design builds on the successful experience of the previous Z-Tech™ Class tugs built for operation across the world.
The Particulars of the ICDAS 19 are as follows:
Length overall – 27.40 m
Beam, moulded, extreme – 12.20 m
Depth, moulded (hull) – 5.05 m
Design draft – 3.80 m, approximate
Gross Tonnage – 369 – 2 x 1920 kW @ 1800 rpm
Power Bollard Pull – 65.0 tonnes
The ICDAS 19 was built and classed to Class NK (Nippon Kaiji Kyokai) notation of:
NS* (CS) (TUG) / MNS*
The vessel has been outfitted for a compliment of up to six people.
The Deckhouse contains a high level of luxury, with overnight cabins for the Master and Chief Engineer with individual ensuite facilities, and a pair of double berth cabins for the deck crew. Galley facilities and a comfortable mess room, allow 24 hour operations to be conducted. The wheelhouse is designed for maximum all-round visibility from driving positions and to both fore and aft deck working areas.
The deck machinery comprises a 35 tonne line pull, hydraulic winch, with a maximum brake holding capacity of 130 tonnes. Similarly located at the “bow” of the vessel is a single, remotely operated fire monitor rated at 1200 m3/hr, supplied by a main engine driven pump. Incorporated into this system are 4 additional 2” hydrants. This provides the vessel with an external fire-fighting capability commensurate with its operation as a superior ship berthing tug.
Ship-handling fenders at the bow comprise of; a single row cylindrical fender of 800mm diameter (400 mm core) and a 300 mm deep “W” fender mounted beneath. A 300 x 300 hollow “D” fender protects the main and foc’sle deck sheer lines, and at the stern is a second cylindrical fender of 400mm diameter (200 mm core).
Main propulsion for each tug comprises two MTU 16V4000M63 engines; each rated 1920 kW at 1800 rpm, driving a pair Rolls-Royce US 205 FP azimuth thruster.
The electrical plant comprises of 2 identical DEUTZ generating sets, each with a capacity of 122 ekW at 1500 rpm (140 kVa, 400 volt, 50 Hz).
The Z-Tech™ class tugs are designed for operation in major ports and marine terminals. The design emphasizes the safe and capable execution of ship-handling operations with large ships, particularly those with extreme flares. The design has also lent itself very successfully in the role as a tender for the US Navy, with both surface and sub-surface ships. The Z-Tech™ design offers omni-directional performance; speed and Bollard Pull astern are almost equal to that going ahead.
