VIDEOS: Marcon named broker for innovative new tug design

MAY 18, 2016 — Purple Water Ltd. has appointed Marcon International, Inc.,Coupeville, WA, as exclusive broker to handle the shipyard licensing for construction of an innovative new tug in the Americas.

Called the Giano tug, the compact double-ended tug has a high displacement tunnel hull form, two large structural keels and a straight-line controllable pitch thruster configuration designed and built solely for ship handing.

With intuitive in-line handling controls, the tug can produce 55 tonnes (70 tonnes) of bollard thrust and pull in all directions at full power with true 360 degree maneuverability, while maintaining a 0 degree list - plus a side-stepping speed of 7 knots – from full ahead to full speed sideways in 10 seconds.

The tug works equally well from the bow or stern and is fitted with 75 tonne escort winches fore and aft.

The design is claimed to has the highest stability numbers of any escort tug afloat, not only in its own 24 m compact class, but also compared with the 32 m escort terminal class.

Two separate engine rooms, a separate generator room and a double hull with integral "W" heavy duty fendering and patented underwater fenders provide a high level of safety, and allow the tug the unique capacity to side thrust and push at full power without listing, while assisting vessels in confined spaces

The Gianotug design is patented over 40 countries.

After four years of research and development, the first tug of this class, is now available in Italy for shipowners and shipyards interested in licensing and building the design to inspect and experience a "hands-on" demonstration of the tug's capabilities.

Built by Chinese shipbuilder Guangdong Bonny Fair Heavy Industry, the 25.75 m x 13.02 m x 5.20 m depth / 5.30 m Giano is powered by twin 1,678 kW CAT 3512C-HD diesels developing a total power of 4,562 HP at 1,800 RPM.

A Schottel SRP-3000 azimuthing drive with a controllable pitch prop is mounted in a straight line at each end, with the tunnel hull specifically designed to eliminate propeller interference.

Topside access and ultra-short shaft lines allow for main engine removal in a few hours.

The U.K. flagged Giano is classed LR +100A1, Escort Tug, FiFi-1 (2,400 cu.m/h) with water spray, Unrestricted – MCA WB Area 1 (up to 150 miles from safe haven).While this first vessel has a 55 t bollard pull, the unified design allows for both 55 t and 70 t bollard pull versions to be built.
