While orders have been reported of late which we will return to, here we look at five notable deliveries involving familiar names in the European arena.
When Leith-based Forth Estuary Towage (FET) addressed the sourcing of a new tug it went to some length to get the choice right including drawing on long experience operating tugs at various ports. Alan McPherson, chief harbour master explained: “Traditionally FET tugs have been Voith Schneider type vessels. However, when looking at our present working patterns we believed that an ASD type vessel would be suitable for our need. I have experience as a pilot on the River Tyne, and had used ASD tugs in the past, and more recently a Sanmar-built vessel. At Forth Ports we also chartered a Sanmar built ASD in 2017 for a few weeks and were impressed by the tugs capabilities.”
This led to a visit to a number of short-listed yards and the subsequent order for a Sanmar-built, RAstar 2800 (Sanmar Terminal) ASD tug and the story is now complete with delivery of the vessel, named Craigleith.
With a length of 28.2m and beam 12.6m Craigleith is powered by MTU main engines each developing 2,000kW and driving Schottel Rudderpropellers providing a bollard pull of 70 tonnes. The ABS-classed tug meets fifi1 notation and is configured for towing over the bow via a DMT winch with a 90t SWL Data Hidrolik towing hook aft. A Palfinger deck crane is included and accommodation comprises two single and three double cabins.
A number of well-known shipyards make the quick delivery of tugs, often from stock a selling point. Opportunities still exist however for those offering longer lead times and Adria-based Cantiere Navale Vittoria has now delivered Cap de Fer to the port authority in Skikda, Algeria, completing a €7m Euro order placed in December 2016.
The launch of hull number C.869 (denoting Vittoria’s 869th vessel) was mentioned previously in MJ and this 26m long, 10m wide ASD develops 3,300hp from two main engines driving azimuth thrusters delivering a bollard pull of 42t and speed 12.5kn. BV-classed Cap de Fer is equipped for harbour and coastal work and has accommodation for seven persons.
The remaining three deliveries all involve Robert Allan Ltd (RAL) designs. While based in Canada, RAL maintains a global presence, particularly in arrangements with European shipyards and once such, Med Marine’s Eregli shipyard recently delivered the RAmparts 2300-MM Med XXV to parent company Med Marine.
Second in a series of six, Med XXV is designed exclusively for Med Marine and delivers 50tbp from two Caterpillar 3512C main engines developing 2,760bKW at 1,600rpm driving Schottel SRP340 azimuth thrusters with 2,100mm fixed-pitch propellers. Two Caterpillar C4.4 gensets provide electrical power for vessel services including deck machinery which includes custom-made SEC Groningen towing winch forward. A Data Hidrolik tow hook is provided aft. Basic dimensions of the RINA-classed tug include: LOA 23m, beam 10.9m and maximum draught 4.8m.
Returning to Sanmar Shipyards, recently the first 70tbp version of the TRAktor 2500-SX tractor Svitzer Vale was delivered to Svitzer A/S of Denmark. The model is designated as the ‘Delicay’ class by Sanmar.
To meet the high bollard pull specification in a hull length of just 25.3m, Svitzer Vale has a relatively high width to length ratio. To prevent potential directional stability issues, the stern features StRAke stabilisers developed by Voith and RAL, another feature worthy of mention is the raised forecastle for operation in rough water.
Finally, we stay with Sanmar for a look at the first example of RAL’s RApport 1600-SX harbour tug which has been running trials with reported ‘excellent performance in all respects’. Larger but still compact harbour tugs feature regularly in this column but there remains a market for tugs suitable for operating at small ports (or large ports with a requirement to handle smaller ships).
The RApport 1600-SX is just 16m long with a beam of 7m and packs a handy 21tbp and speed 11.5kn from a conventional twin-screw arrangement with nozzles and four rudders. Power is via 650kW Caterpillar C18 engines. A 25t towing hook is supplied as standard with electric or hydraulic winch available as an option. It can also be fitted out as a lineboat with standard pipe rope guards.
