The inland waterway tanker Servio is built to sail the rivers and canals of Europe and is the latest in a series of such tankers with multinational origins
The inland waterways of Europe are a vital transport network. According to the latest data, 1.2 tonnes of freight per inhabitant was transported on EU waterways in 2019 and freight transport performance actually increased by 6.2% in the same year. Refined petroleum products made up the second largest category of cargo in 2019 (16.2%) after metal ores. Refined petroleum product movements grew in 2019, but crude oil movements shrank by 0.9% to 7.5%.
Within Europe, inland waterway tankers provide a vital bulk delivery system to and from refineries and customers, such as chemical factories; they also remove a significant tonnage of heavy goods traffic from the roads and reduce emissions levels.
Servio was delivered to Dutch owner Larosare BV in January 2021 and is managed by R.S. Shipping BV (Rhoon), which is owned by two brothers, Ronald and Sandor Hartenhof. The owned fleet consists of two ships. The company is fully accredited with the standards set out in Tanker Management and Self-Assessment (TMSA) and the European Barge Inspection Scheme (EBIS) and is a Green Award recipient. R.S. Shipping operates across all the inland waterways of Europe, from ARA (Amsterdam, Rotterdam, Antwerp) to Switzerland and everything in between.
Servio is commercially managed by R.S. Shipping and chartered out to Burando Barging, which is one of the largest inland barge operators in North West Europe with a fleet of 60 state-of-the-art double hull barges for transporting bulk liquid products such as gasoline, mineral oils, light chemicals and vegoils. The company has an extensive network of contacts throughout the West-European waterways, from Maastricht to Den Helder, and all ports and terminals positioned in the France, ARA, Germany regions, including the Rhine and associated canals.
Servio is another inland waterway tanker in the Burando Barging commercially-controlled fleet to be constructed in the following manner: the hull was constructed in Serbia, at the Shipyard Kladova, a shipyard owned by the Dutch brothers Reinder and Lambert Gerrit de Jonge, which run the family-owned Gebr. De Jonge shipyard in Lochem.
“Actually, very few inland waterway tankers are entirely constructed in the Netherlands,” said Burando Barging director Joey de Gruijter.
Gebr organised the construction. De Jonge shipyard forged links with Shipyard Kladova in Serbia in the early 2000s and now specialises in having hulls constructed to Gebr. De Jonge designs in Serbia. The Serbian shipyard also undertakes the construction of pipework, in stainless steel if required, and superstructures.
In the case of Servio, the hull, superstructure and some of the pipework was fabricated in Serbia. Shipyard Kladova is on the Danube, on an artificial lake created by two locks, and the location means the water level can be controlled for the float-out of large structures. Shipyard Kladova is capable of constructing vessels up to 3,650 tonnes. The shipyard’s synchro lift can lift vessels up to 140 m in length and 22 m wide.
From Shipyard Kladova, Servio was towed up the Danube, over the continental divide, down the Mains and Rhine to the Netherlands, to the specialist fitting-out shipyard Oonincx Scheepsonderhoud BV at Ooninxs in Wekendam. The yard was founded in 1991 and works both as a main contractor and sub-contractor fitting-out inland vessels.
The uncoated tanks are served by deep-well pumps with the motor units mounted on the deck, driving centrifugal pumps at the bottom of the tanks. The pumps were fabricated and supplied by DW Pumps, a Dutch company founded 40 years ago to specifically serve the inland barge sector. The final pipework outfitting and testing was undertaken by PSI Piping of Papendrecht. Winches and deck equipment were supplied by van Wijk. The hull coating is Nelf, a Dutch brand popular among the inland waterway community.
Tank ullage and alarm instrumentation was installed and tested by Hoveko BV in the Netherlands. Erwin van den Hooven of Hoveko noted that the company has developed its own software for tank measurement. Hoveko also supplies Klay pressure transmitters.
“Very few inland waterway tankers are entirely constructed in the Netherlands”
The ballast water system is Liquid Control Trading BV. Inland waterway vessels do not require ballast water treatment systems, but do need to ballast down to clear low bridges. Servio can take in up to a 1,000 tonnes in this manner and with the retractable deckhouse, can pass under bridges with an air draught of 4.5 m.
The stability calculations were undertaken by Dutch naval architects Groenendijk and Soetermeer, based in Dordrecht, which has a vast portfolio of similar work and projects for tankers, container ships, passenger ships and coastal vessels.
The boilers are 900kW Heatmaster units.
The fitting out of Servio took place at the wharf of Hoogendoorn Maritieme Betimmeringen en Interieurbouw, an outfitting company that has experience of luxury yachts, such as Lady Thuraya, and the quality of workmanship carries over into the accommodation of Servio.
The main propulsion unit is a Cummins QSK38M1, generating 1400 hp at 1800 rpm. Cummins, and this engine model in particular, is a favourite among inland waterway vessels in Europe, and assures the power and reliability expected of a tank ship. The main engine turns a 1.75 m propeller through a Masson Mw W5200 gearbox with 5.91:1 ratio. This gives a prop rotation of 302 rpm. Fine tuning was carried out by VICUSdt of Spain, the company stating that it contributed propeller and CFD hydrodynamic analysis work.
The auxiliary engines include an EU Stage IIIa-compliant Cummins X15-powered pump-style bow-thruster and a John Deere and a JCB generator-set combination. The auxiliary engine produces 1800 rpm, necessary to meet demand for more voltage from the generator or more power for cargo pumping or the bow thruster. This is believed to be the first installation of a dual-use AC/DC in-house-built system with a double bearing Marathon generator. All engines and generator sets were supplied and installed by Marine Power Drechtsteden B.V. of Dordrecht, Netherlands.
