Med Marine begins building six Ramparts tugs
Med Marine operates harbour tugs with fire-fighting equipment in Turkey

Turkish shipbuilders have turned to Robert Allan for tug designs for harbour and terminal operations, and escort duties. The latest agreement involves Med Marine

Med Marine has started construction of a new design of harbour tug exclusively designed by Robert Allan Ltd. Initially, six tugs will be built at the Ereǧli Shipyard in Turkey, with steel cut for the first of these vessels in April. These tugs will be RAmparts 2300-MM design vessels, which is a variant on Robert Allan’s RAmparts series of versatile and multi-purpose compact azimuth stern drive (ASD) tugs. They will be classed by RINA and have various maximum bollard pull ratings, ranging from 35 tonnes to 50 and 60 tonnes.

The Med Marine 23m tugs will be designed for harbour and terminal operations, and coastal towing. According to Med Marine group chief financial officer Yıldız Bozkurt, the first vessel is expected to enter service in the fourth quarter of this year. They will have a 10.9m moulded beam and a maximum draft of 3.15m.

The ASD tugs will be equipped with two CAT 3512C main engines with a power rating of 1,380 kW at 1,600 rpm, said Mr Bozkurt. They will be fitted with a pair of Schottel SRP 340 FP propellers and deck machinery from Central Industry Group subsidiary Ship’s Equipment Centre Groningen. This includes SEC winches, aft capstan with a pulling force of 50 kN and anchor capstan.

Mr Bozkurt said the front towing winches will be custom made for Med Marine with a pulling force of 300 kN and holding force of 1300 kN. The RAmparts 2300-MM tugs will be compliant with the Maritime Labour Convention (MLC) with “high-quality and great-comfort accommodation, a captain’s cabin, an officer cabin and two double crew cabins”. They will be classed with general notations as follows: RINA C, AUT-UMS, Firefighting Ship E with water spray, unrestricted navigation, Greenstar 3 and MLC Design.

Med Marine provides a broad range of towage, pilotage and mooring services in the busiest ports of Turkey, in Izmit and Iskenderun Bay, said Mr Bozkurt. It executes salvage, wreck removal and oil pollution prevention operations around the world and also builds tugboats, mooring and pilot boats.

Robert Allan has made other co-operating agreements with Turkish shipyards. At the end of last year it signed a deal with Uzmar Shipyard to jointly develop tugs based on the RAstar 3000-W design. These 30m tugs will have propulsion packages of up to 90 tonnes of bollard pull while still remaining below 500gt in weight. Uzmar said these escort tugs will be capable of safely performing steering and braking manoeuvres, as well as carry 140m3 of fuel and 30m3 of fresh water.

These will be 13m-wide tugs with a maximum draught of 5.5m and accommodation for 10 crew. The design can be scaled to different lengths, said Uzmar proposals and project manager Hasan Ata. He added: “We will start construction in early 2017. The vessels should be available to be purchased in 2018.”

Uzmar recently sold two tug newbuildings to Offshore Engineering Development Co (IOED) of Venezuela. These were built on a speculative basis with Caterpillar engines and Schotel fixed pitch propellers. These 25m tugs achieved 60 tonnes of bollard pull during sea trials.

Sanmar works with Robert Allan on designing ASD escort and harbour tugs. In March this year, it gained an order for a new 80 bollard pull tug from Svitzer. This will be a RAstar 2800 escort tug, to be named Svitzer Adira. Svitzer said it will deploy this tug in Southampton, UK to strengthen its fleet to meet current and future requirements of container and tanker shipping.

Svitzer Adira is due to enter service in May this year. It will be configured for demanding escort operations and maximum efficiency in handling large vessels in confined spaces. It will be powered by two Caterpillar main engines producing 2,525 kW and will be FIFI 1 compliant.
