Agile, rugged and compact first of class

by Hans | February 12th, 2015

The high level of cooperation between both the operational and construction teams of Sanmar AS and the designers at Robert Allan Ltd has resulted in another new design of tug/workboat

Named Yenicay, this first of class compact ASD achieves a 30 tonne bollard pull in a vessel measuring 18.7m x 9.2m with a draft of 3.7m. The ABS classed vessel has joined Sanmar’s own fleet of three other tugs at Petkim Port, Aliaga, Izmir, Turkey.

Constructed in Sanmar Tuzla Shipyard, this rugged craft is powered by a pair of Caterpillar C32 main engines, each developing 970kW at 1800 rev/min driving Veth VZ-900 azimuth drives with carbon composite shafts turning 1700mm dia propellers inside high efficiency nozzles with stainless steel inner surfaces. Auxiliary generator sets are also by Caterpillar –  a pair of 86ekW C4.4s. For external fire-fighting operations, the vessel is equipped with a main engine PTO driven 600m3/h capacity pump and a manually operated foam/water monitor, both supplied by FFS.

Below deck, Yenicay has two twin-berth cabins, a mess room, pantry and WC. All floors are covered with IMO approved imitation teak and special care has been given to the resilient mounting of all engines and essential equipment, As a result, the sound level was measured as 60dB in the lower accommodation during sea trials. Both wheelhouse and accommodation are heated, vented and air-conditioned by chiller system, moreover, an optional split unit is available for installation in the wheelhouse as a heat/climate package.

For towing operations, the vessel’s deck machinery consists of a DMT TW-E100kN electrical forward winch and a Data aft tow hook. Cast stainless steel towing staples on both fore and aft decks give the vessel the capability to tow in both directions.
The vessel is heavily fendered with 500x250mm cylindrical fendering at the bow extending below with 300×300 W type. Sides and stern are covered with 300mm D type fenders.

Sea trials confirmed the advance performance predictions with a bollard pull of 31 tonnes and a free-running speed of 12 knots being attained.
