Med Marine delivery to Arpaş
Turkey’s Med Marine has taken delivery of a powerful ASD built by Ereğli Shipyard: a Med Marine Group company. Peter Barker takes a closer look at this latest in a series.
Turkey’s shipbuilding industry regularly brings news of activities, particularly in the tug-building sector. Ereğli Shipyard is located in the Black Sea, next to the recently privatised Ereğli Iron and Steel Works and in common with other yards in the country has an arrangement with Robert Allan Ltd (RAL) to build vessels from the Canadian naval architect’s shiphandling tug catalogue.
Istanbul-based Med Marine is a shipbuilding company providing towage, pilotage and mooring services in Turkey, operating a diverse fleet of modern tugs, all of RAL design. Med Marine added Ereğli 51 (Med Yarımca) to its fleet last year and the sister ship we take a look at in this Vessel Launch feature concerns the RAmparts 2500W with the project name Ereğli 52 recently delivered to Arpaş Pilotage and Towage.
Ereğli 52 has towing, pushing, mooring and fire-fighting operations listed as its basic functions and meets the requirements of Italian classification society RINA with the notation: C+ Tug + AUT-UMS, unrestricted navigation, fire-fighting ship 1, water spraying, MLC design, Greenstar3.
The vessel is of a compact design with a length overall of 25.3m and beam overall 12m. Depth moulded is 4.6m and draught (loaded) 5.68m with a gross tonnage of 365 tons. Tank capacities include: fuel oil 96.6m3, fresh water 11.2m3, sewage 4.8m3, oily water 2m3, lube oil 2m3, used oil 3m3 and foam 4.9m3. Performance figures are stated as 72.15 tons bollard pull (maximum) and 70.7 tons static and a vessel speed of 12 knots.
Ereğli 52 is built to a standard ASD configuration with Caterpillar providing both main and auxiliary machinery. Main engines comprise two Caterpillar 3516C D rating diesels developing 2,100kW (in total) at 1,600rpm driving two Schottel SRP1515 CP azimuthing thrusters: each thruster turns 2,600mm diameter, CU3 material propellers. Caterpillar also supply the auxiliaries in the form of two C4.4, 86ekW, 1,500rpm generator sets.
We look in more detail at the engine room later but turn next to the deck equipment. The vessel is particularly well-equipped for towing over both the bow (for shiphandling) and the stern. The Netherlands-based SEC Groningen was founded in 1890 and provide winches both forward and aft.
On the forecastle an SEC electric, frequency-controlled combined anchor and towing winch is provided capable of accommodating 20.5mm U2 chain with one chain wheel. The ground tackle itself comprises a single 214kg high holding power anchor along with 302.5m of short-link 20.5mm chain. The forward towing function comprises two towing drums each with capacity for 200m of 52mm rope along with one warping head.
On the aft deck SEC provide an electric, frequency-controlled single-drum towing winch with capacity for 600m of 52mm towing medium. Also aft is a Mampaey DCX 70/100 quick release, disc-type towing hook. Two, eight-person liferafts are situated on the top deck and completing associated equipment is fendering comprising ‘D’ and ‘W’ fendering around the hull itself and rubber cylindrical bow fendering.
Returning to the engine room, auxiliary equipment includes a 25m3/hr bilge pump and a cooling water system provided by Sperre Pleat along with a Heinen-Hopman air conditioning installation with a capacity of 2.16m3/hr supplying the accommodation and wheelhouse. Ventilation is provided by two Salor centrifugal supply fans (32,000m3/hr, 15,500m3/hr and 1,000m3/hr) and three exhaust fans (50m3/hr, 100m3/hr and 560m3/hr).
FFS supply the external firefighting equipment via an integrated control system for two monitors supplied by separate pumps connected to each main engine’s PTO PLC-based interlock system. Each monitor has a capacity of approximately 1,314m3/hr. Ereğli 52’s accommodation has a capacity for six persons in two single and two double MLC-compliant crew cabins.
Moving on finally to the wheelhouse, the layout follows the now standard form of split-consoles with an upholstered chair on rails running in between. A combined power and steering control for each thruster is located on each console with the winch controls at the after end of the right-hand console (looking forward). Display monitors including the radar are positioned low down around the consoles maintaining clear all-round visibility for the master.
JRC dominate the list of navigation and communication equipment based on compliance with GMDSS Area A3 operation. The radar is a JRC JMA-5212-6 model supported by a JRC JLR-21 GPS compass and JLR-7500 GPS navigator. A JHS-183 AIS system is included along with a JFE-380-22 echo sounder and NCR-333 Navtex receiver.
Two JRC JSS-2150 VHF sets are provided and completing the wheelhouse equipment list are: a Seematz 24V, 1000W searchlight, a NASA clipper wind system, Reflecta 1-120MM magnetic compass (mounted on the wheelhouse roof with a readout reflector inside), Navitron NT921 MkII autopilot, Joton Trons 60S EPIRB and Jotron Trons AIS SART.
