Trio of new tugs for Svitzer UK
Mon, 09 February 2015
The UK fleet of Svitzer Towage has received a boost with the arrival of three new tugs, two built in Vietnam and one in Turkey.
Svitzer Europe are dominant providers of harbour towage activities in the UK, active in 15 ports. The different operational profile of each location demands particular vessel types and pulling power as evidenced by these latest arrivals of one single azimuth stern drive tug and a pair of azimuth tractors
First tug to mention is the Sanmar built Svitzer Tyne.Built to a design from Robert Allan Ltd this tug follows the earlier delivery of a sister vessel also for Svitzer, destined to operate in Peru. Both are examples of Sanmar’s Boğaҫay series based on Robert Allan’s RAmparts 2400SX design, the SX denotes the series as being exclusively developed for Sanmar Shipyard. Exceptionally quick delivery from date of order was a crucial aspect of both the Peruvian and UK contract awards.
Svitzer Tyne is classed by ABS and carries the notation ABS+ A1, +AMS; Unrestricted service. Main dimensions are LOA 24.4m, length DWL 23.38m, breadth moulded 11.25m, depth moulded 4.38m and maximum draught 5.1m. Tank capacities include 84,200 litres of fuel oil and 10,600 litres of fresh water.
Main machinery comprises two electric start Caterpillar 3512C engines rated 1,765kW at 1,800rpm providing 60tbp via two Rolls-Royce US 205FP thrusters incorporating 2,400mm Ni-Al bronze propellers. The engines are installed at a slight decline towards the free end (no more than 8%) and the port engine has a PTO shaft to drive the Fi-Fi pump. Ship’s service generator sets provide electrical power via two Caterpillar C4.4 230/400V, 107kVA, 50Hz diesels.
Svitzer Tyne is equipped primarily for towing over the bow for which a DMT type TW-E 250KN double drum winch is fitted rated at a maximum pull of 250KN (first layer) and braking force of 1,250KN (third layer). The winch has storage capacity for 135m of 40mm UHMWPE rope. The aft deck is largely clear with a closed transom and towing provision over the stern is supplied by a Data Disc type towing hook.
The two Damen ATD Tug 2412 Twin Fin examples Svitzer Eston and Svitzer Bargate were built in Damen’s Vietnam yard and arrived as deck cargo at their Vlissingen Shiprepair facility for drydocking and inspection late in 2014 aboard the heavylift vessel Calypso. Meanwhile around the same time a Redwise delivery crew brought the Svitzer Tyne from Sanmar Shipyard in Turkey direct to the Port of Tyne UK.
A prominent UK operator of the Damen ATD series tugs is Serco Marine which has four larger 2909 versions in operation and a particular difference between the two is the twin-fin arrangement with the Svitzer examples compared to the conventional single fin of the Serco Marine tugs. Svitzer Eston and Svitzer Bargate are classed by Lloyds Register and carry the notation +100 A1 Tug [+] LMC UMS with main dimensions of LOA 24.74m, beam OA 12.63m, depth at sides 4.6m and draught of 5.85m. Tank capacity figures include 69.8m3 of fuel oil and 8m3 of fresh water.
Main engine provision is from two Caterpillar 3516C TA HD/D diesels with a total output of 4,180bkW (5,600bhp) at 1,600rpm. Power is transmitted to two Rolls-Royce US 255 azimuth thrusters incorporating Rolls-Royce ‘built in’ type slipping clutches with 2,600mm diameter propellers. Auxiliary machinery includes two Caterpillar C4.4TA, 230/440 V, 86kVA, 50Hz generator sets. Performance figures indicate a bollard pull (ahead) of 67.5 tons and speeds of 12.5 knots ahead and 11.9 knots astern.
The two Damen vessels’ after decks are each home to a hydraulically driven split drum winch with 33 ton pull at 11m/min and 150 ton brake load incorporating a line pull measurement system. An electrically driven 10m/min anchor winch with warping head is located forward. The fendering system consists of a cylinder and block arrangement aft and a D-fender on the sides and bow.
