Finarge Armamento Genovese’s latest addition was designed by Cintranaval and built by Bogazici as a powerful and multipurpose escort tug
When a subsidiary of Italian tugboat owner Rimorchiatori Riuniti took delivery of Paraggi from a Turkish shipbuilder, it started operating one of the more powerful and versatile escort tugs in the Mediterranean region.
Paraggi is a multipurpose escort tug built by Turkish shipyard Bogazici to a design by Cintranaval Ship Design. It comes with a hull specifically designed for stable escort duties and onboard equipment for multiple towing requirements.
Finarge Armamento Genovese started operating the 32.5-m escort tug in May this year. Paraggi is an azimuthing stern drive (ASD) tug built to a CND-15231 design for escort duties and harbour operations. It has 70 tonnes of bollard pull and a top speed of 13 knots. This power comes from an engineroom furnished with Caterpillar engines and auxiliaries and propulsion supplied by Schottel.
Paraggi, registered in Genoa, is classed by RINA as an escort and salvage tug with unrestricted navigation and fire-fighting capabilities to FiFi 1 class. Paraggi is equipped with a fore escort-towing winch and a towing winch and towing hook on the aft deck, allowing the tug to perform towing operations both ahead and astern, said a spokesman for the shipbuilder, Bogazici.
Additionally, the vessel is equipped with a stern roller and towing pins and the free deck in the aft is reinforced for loads up to 5 t/m2. Its fore deck is free of obstacles which is a benefit during escort and towing operations.
Paraggi was designed with a comparatively small draught of 4.3 m for access to shallow harbours. Cintranaval’s CND-15231 design was chosen for its hull lines and appendages that improve Paraggi’s escort performance without compromising its overall length or draught, said the Bogazici spokesman. This is important in maintaining good seakeeping during escort operations, when working with the fore winch and sailing ahead.
Bogazici built this tug with a raised forecastle deck that minimises water on deck, while the wheelhouse was conceived with good visibility all around the tug and good ergonomics for the master. It has accommodation for up to 10 people.
In the engineroom, two Caterpillar 3516C type main engines, each deliver 2,100 kW of power at 1,600 rpm. There are two Caterpillar C7.1 generator sets that each generate 150 kW of electrical power at 1,500 rpm and 50 Hz, plus there is a smaller harbour genset.
Paraggi's ASD capabilities come from two Schottel SRP 1515 controllable pitch and azimuthing propellers, with a 160 kW electric-driven bow thruster for extra manoeuvrability. It has a strong fender system, supplied by Yantai Taihong Rubber, which protects the vessel’s hull.
Deck and FiFi
Its deck machinery includes a Kraaijeveld 70-tonne single split-drum escort towing winch on the fore deck. It also has a Kraaijeveld 45-tonne double-drum towing winch on the aft, plus towing pins, reel winder and stern roller of 130 tonnes.
Paraggi has a fully hydraulic and foldable knuckle boom crane, supplied by Palfinger Marine. This PK18500MC crane has four sections with a boom extension of up to 12.4 m and lift capacity of 1.1 tonnes.
Fire-fighting capabilities are to FiFi 1 class, supplied by Fire Fighting Systems with two FFS1200 remotely operated water monitors and deflector. These can rotate 360˚ and elevate between -20˚ and 80˚ and have a throw length of more than 120 m and height of 50 m.
This FiFi 1 system has its own water spray system with two pumps of 1,350 m3/h capacity at 1,820 rpm, with transmission and a remotely operated hydraulic clutch. This SFP XP pump has a stainless steel shaft and is driven by power take-off from the main engines.
Paraggi’s wheelhouse equipment was mostly supplied by Sperry Marine, Saab and Cobham Satcom. It includes VisionMaster FT X-band radar, autopilot and gyrocompass from Sperry Marine. This subsidiary of Northrop Grumman also supplied a magnetic compass, Naviknot 350 E speed log, anemometer and ES 5100 echosounder.
Saab delivered an automatic identification system R5 Supreme AIS and global positioning system. McMurdo supplied a Navtex and search and rescue transponders, while Lilley & Gillie delivered a SOLAS signalling lamp and Martek supplied the Navgard bridge navigation watch alarm.
Cobham Satcom were responsible for the communications equipment including the radio devices for the Global Maritime Distress and Safety System, the Sailor 6222 antenna, Sailor 6310 medium and high frequency radio telephone, Inmarsat Mini-C and SP 3520 handheld VHF radio. It also supplied Sailor 150 FleetBroadband satellite communications set. Zenitel provided an onboard telephone system with accessories and talkback function.
