Med Marine, Uzmar and Sanmar have adapted Robert Allan designs and ramped up construction of tugs under contracts and for their own fleets
Turkish shipyards are busy constructing fleets of tugs for clients and their own requirements, while producing some on a speculative basis. Turkish yards are using off-the-shelf models from Canada-based Robert Allan, and adapted these for their own designs to meet a multitude of client power and manoeuvrability requirements.
Med Marine has been more active than this time last year, delivering tugs each month for its own Turkish-based fleet and for clients. This shipyard is half way through a tug newbuilding campaign for its own fleet and completed two tugs for other owners in Q1 2018.
In April, Med Marine completed Med XXVI, boosting its own Turkish fleet to 23 vessels. This tug was built to a RAmparts 2300-MM design that is adapted from a Robert Allan coastal towage tug model.
Med XXVI was the third of six RAmparts 2300-MM model tugboats that Med Marine is constructing for its fleet, Med Marine spokesman Asli Köseoðlu told Tug Technology & Business. This 23 m azimuthing stern drive (ASD) tug has been deployed to Izmit Bay, in the Sea of Marmara, along with other Med Marine tugs, he said.
Med XXVI was built for harbour and terminal operations and coastal towing with a top sailing speed of 12 knots and bollard pull of 50 tonnes. It has Caterpillar engines and generators, Schottel thrusters and is classed by Italy’s RINA Services.
For other clients, Med Marine supplied a harbour tug to Arpas Pilotage and Towage in February. Eregli 52 is a RAmparts 2500W design ASD tug with 73 tonnes of bollard pull and a maximum speed of 12 knots, said Mr Köseoðlu.
This is achieved using two Schottel SRP1515 azimuthing thrusters with controllable pitch propellers of 2,600 mm diameter, driven by two Caterpillar CAT 3516C diesel engines that have a total output of 4,200 kW.
Eregli 52 is a RINA Services-classed, 25.3 m tug with a FiFi1 fire-fighting system that includes a diesel-driven pump that can deliver 2,600 m3/h of water to two electrically-controlled monitors.
It also has two Caterpillar C4.4 gensets that produce total of 172 ekW of electrical power for vessel services, including deck machinery. SEC Groningen supplied electric-controlled anchor and towing winches.
Eregli 52 is part of Arpas’ fleet operating in Ambarli Port, on the north shore of the Sea of Marmara, 34 km from Istanbul, Turkey. Arpas provides anchoring, berthing and unberthing services to ships and offshore drilling rigs in the port complex. It also provides tugboat and pilotage services to tanker moorings and terminals in the area.
Arpas is a partnership of Kumport, Akçansa, Mardas, Marport and Limak that owns quays in the Ambarli Port. It operates five other tugboats, two mooring vessels and a port security boat.
In March, Med Marine sold a 22.5 m tugboat to Port of Beirut, said Mr Köseoðlu. This RINA-classed tug operates out of the Beirut pilotage station in Lebanon with a top speed of 12 knots and 40 tonnes of bollard pull. It has two 12-valve engines supplied by Rolls-Royce subsidiary MTU (Series 4000 type M61R), which produce a total output of 2,280 kW and drive two twin-screw Promarine propellers.
Caterpillar supplied two 2438B generator sets that each generate 75 kW for vessel systems including deck machinery, such as towing winches. Masson supplied the MMW7400 model reverse reduction gearboxes.
This tugboat has accommodation for six people and fire-fighting capabilities thanks to a Marsis-supplied FiFi 1 system that can deliver 1,200 m3/hr to two electrically-controlled monitors.
Also in March, Med Marine won a contract from Italian shipping group Rimorchiatori Riuniti to supply an escort tug for Tug Malta, said Mr Köseoðlu. This will be a RAstar 3000-W class tugboat was designed by Robert Allan for enhanced escort towing and seakeeping performance. Rimorchiatori Riuniti engaged with Robert Allan before awarding the construction contract to Med Marine.
It will be a 29.7 m tug with a bollard pull of 80 tonnes and a maximum sailing speed of 13.0 knots. MTU will supply two 16-valve engines (Series 4000, type M65L) for this vessel that will be able to each generate 2,560 kW of power to drive two Rolls-Royce US255 thrusters. The tug will have accommodation for eight people, a FiFi 1 class fire-fighting system and Rolls-Royce deck machinery.
Tug Malta also took delivery of an ASD escort tug from Damen Shipyards in February. St Angelo was built by Damen Galati with two Caterpillar engines with a total output of 5,050 kW. It is a Damen ASD 2913 design, 28.1 m tug with a 4.14 m draught and top speed of 13 knots.
This 431 gt tug was classed by Bureau Veritas for escort and supply duties with firefighting equipment to FiFi 1 standards. It can also recover oil with a flash point of more than 60°C. Other tugs in Tug Malta’s fleet include Sea Salvor and Spinola, which saluted arrival of St Angelo by spraying water from their firefighting monitors.
Rival shipbuilder Sanmar is using designs that Robert Allan produced exclusively for the shipyard. The latest of these is tug Ashdod, which is the second of a new VectRA 3000 series of vessels. This 30.25 m tug joined sister vessel Arie A in the Israeli port of Ashdod in March. It was built with Voith Schneider propellers (VSPs) for Italian operator Tripmare Spa.
Ashdod has a bollard pull of 70 tonnes and maximum speed of 12.5 knots. These are achieved with a pair of Caterpillar 3516C diesel engines that each generate 2,525 kW of power at 1,800 rpm. These drive forward-located Voith type 32-R5 250 cycloidal propellers via a pair of Reintjes WAF 843 clutch and reduction gearboxes.
Sanmar said these reduce transmission losses, which increases the overall propulsion efficiency. Reintjes devices also enable the drives to be de-clutched at idle, which reduces fuel consumption. By using these high-speed engines, Sanmar was able to reduce the space occupied by drive machinery, which lowering the weight without affecting tug performance.
Ashdod is also equipped with a DMT-supplied hydraulic-driven and double-drum winch with tension indication clutches and 800 kN capacity. Both drums have a brake capacity of 200 tonnes.
This delivery followed the shipping out of a Yenicay-class tug, Al Jimi 1, for Abu Dhabi Ports’ tug operating unit Safeen in February. This is based on a Robert Allan RAscal 1800 model and has 32 tonnes of bollard pull and top speed of 12 knots.
Al Jimi 1 started operating in both Musaffah and Zayed ports in the UAE in February. It is an ASD, 18.7 m tug with Veth VZ-900 azimuthing stern thrusters. These are driven by a pair of Caterpillar C32 main engines each developing 969 kW at 1,800 rpm. Because of the hot environment these tugs will operate in, they have an upgraded HVAC system serving all accommodation spaces and improved overall fan capacities, said Sanmar.
Also in February, Sanmar delivered a 25.3 m tractor tug Kinaki to owner Port Taranaki to support berthing at the port on the west coast of North Island, New Zealand. This was built to a Sanmar-adapted Robert Allan design TRAktor-Z 2500 SX.
Kinaki has forward-mounted Z-drives in a tractor format that, according to Sanmar, were designed for maximum efficiency in both harbour, ship-handling and towing duties. This ABS-classed tug has 60 tonnes of bollard pull.
Sanmar technical director Ali Gurun said other tugs had been delivered in the first four months of 2018 to Svitzer, SMS Towage and an unnamed owner in northern Spain. He said Sanmar had a strong orderbook of tug orders after more contracts had been secured this year for ASD tugs.
A tug century
Turkey’s Uzmar Shipyard has adapted Robert Allan models for its newbuild construction programme using the RAstar 3000-UZM and RAmparts 2300-UZM designs. It is also working on new exclusive DRAfter 2500-UZM and Rave 3200-UZM tug designs, based on Robert Allan series.
In April, Uzmar celebrated construction of its 100th tug to a Robert Allan design. This milestone tug is being built to a RAstar 3200-W design for SAAM Smit Towage Canada. This ASD tug will be built to support terminal operations and to provide escort services on Canada’s west coast. It is scheduled to be delivered in Q1 2019.
Uzmar said it will be built for all ship-handling roles, including berthing, unberthing and escort duties, even in heavy weather conditions. It will be optimised for generating high indirect escort forces and be capable of providing towing operations from the stern, a shipyard spokesman said.
This RAstar 3200-W tug will be one of the first tugs to feature an IMO Tier III emissions-compliant propulsion package. It will have other notable features, such as gas detection, explosion-proof deck equipment and fire-fighting capabilities to FiFi 1 capabilities.
Uzmar is building eight other tugs to Robert Allan design at its shipyard in the Kocaeli free zone, Turkey. These tugs include six RAstar 3200 tugs and a pair of RAmparts 3000 tugs. After these, Uzmar intends to build at least another 20 vessels with bollard pulls of between 50-85 tonnes.
