Successful towing tests with new Damen RSD Tug 2513

Being back from a successful European tour that has taken her to the shores of Malta, Italy, France, Spain, Portugal, Gibraltar, Great Britain, Belgium, the Netherlands and Germany, Damen’s new RSD Tug 2513 INNOVATION has taken part in towing tests in the Port of Felixstowe, UK. The intention of the tests was to allow the INNOVATION to undertake a number of tows, in various positions, in a controlled and safe manner, gradually building up until she took on a powered indirect on ultra large container vessel (ULCC) the OOCL Hong Kong, 400m x 14.8m draught, departing from Trinity 9.

Damen has developed the RSD Tug 2513 to meet the demand for tugs that are compact for harbour operations, yet have the power and flexibility to manoueuvre even the largest vessels, quickly and efficiently. The innovations featured in the vessel design are based on evolved, proven Damen technologies. The tug offers increased safety, sustainability, reliability and efficiency. A significant feature of the RSD Tug 2513 is its low fuel consumption and emissions. The vessel is IMO Tier II compliant and prepared, with a simple, easy retrofit, for IMO Tier III.  The project has received funding from the European Union’s Horizon 2020 programme under grant No. 636146.  

The Port of Felixstowe was selected as it enabled Svitzer to participate in the tests and because the location allowed the demonstration of the RSD Tug 2513’s ability for a powered indirect tow. Setting up the demonstration, Damen worked in close cooperation with Svitzer, and with the port as well as pilots from Harwich Haven Authority. The tests took place over ten days between 28th July and 6th August. Before the first towage operation, the INNOVATION underwent a thorough fit-for-purpose audit, and extensive sea trials carried out by senior special category ship pilots Ian Love and Prithvi Singh, following which she was ready to go. Over the successive days she performed no less than eight towage operations on vessels up to 400 metres in length, in conjunction with tugs from Svitzer’s fleet.

One of the tripping pilots said, “The purpose of this trip out was to test the tug. She proved very responsive, nimble, manoeuvrable and dry – even going backwards at 13 knots.”

Captain Ian Love reported, “It was unanimously agreed that vibration and noise levels are significantly less throughout the accommodation while towing and pushing, even on full power. The Tug’s ability to side step at speed and run ahead of the vessel are without doubt her strongest attributes. Her ability to run astern on one unit at speed – while the stationary unit is creating drag – and yet remain extremely stable – can only be considered an up-lift in safety.”

Captain Love added: “With ever increasing demands made on pilots having state-of-the-art towage available allows us to deliver the service ports require, The RSD Tug 2513 would be a welcome addition to any tug fleet handling ULCC.”

Kasper Nilaus, Managing Director, Svitzer Europe, said: “As the world largest towage provider, innovation in our industry is very close to our hearts at Svitzer, so we are very pleased to have supported the successful test of the Damen RSD tug especially in Felixstowe, where the demand for powered indirect towage is more prominent than anywhere else in Europe.”

Damen Sales Manager Erik van Hattem said, “Now that the RSD Tug 2513 has demonstrated its capabilities, we are very much looking forward to seeing this next generation tug in operation in ports in the near future.”
