Encouragingly for our new partnership, the previous vessel in this series was equipped with an identical propulsion package, but from a different supplier.” AKA’s CEO, Jason Aspin, said: “We are excited to deliver on this first order together with our new partner, MAN Diesel & Turbo. Our expertise in energy management, and electrical-system integration, combined with MAN’s vast experience in power-train solutions, allows us to deliver a completely integrated power and propulsion system for this vessel, making it a WIN-WIN-WIN between our partnership and this client”. The partnership with AKA represents part of MAN Diesel & Turbo’s strategic development programme, "Basecamp 3000+", launched in 2016 when the company announced strategic acquisitions and partnerships to expand its product range with respect to the global trends of decarbonisation and digitisation. WÄRTSILÄ HYBRID FIRST FOR FISHERIES A new fish processing and transportation vessel building at Spain’s Balenciaga shipyard for Norwegian owner Hav Line, will be powered by a Wärtsilä arrangement based around a 10-cylinder W31 prime mover. The low-emission vessel, a Wärtsilä design, features a hybrid propulsion solution that makes use of a battery-powered power take-in/ power take-off system. By absorbing most of the engine's load fluctuations and vessel load variations through the batteries, the engines can be operated close to its optimum design point, thereby providing the highest level of efficiency. When the vessel is delivered next summer, it will be the first fisheries vessel to adopt such a power arrangement. "The fish farming industry, like other marine industry sectors, is seeking better ship designs and greater efficiencies that reduce overall operating costs and lessen the environmental impact. Wärtsilä is proud to have been selected for this project that introduces the world's first hybrid propulsion system for this kind of vessel," says Riku-Pekka Hägg, Vice President, Wärtsilä Ship Design. Wärtsilä has also been contracted to supply auxiliary engines, gears, sterntube seals and bearings, CP propellers and remote control and automation systems. Following its introduction in 2015, the Wärtsilä 31 was recognized the world's most efficient four-stroke diesel engine by Guinness World Records. MTU ENGINES POWER 90TBP TUGS Rolls-Royce and Turkey’s Sanmar Shipyards have signed a contract for the delivery of eight MTU Series 4000 engines for four new terminal tugs, including an option for a further four engines. The tugs will be fitted with two 16V 4000 M73L MTU engines, each delivering an output of 2,700kW at 1,850rpm. Ali Gürün, Projects Director of Sanmar Shipyards, commented: “We were impressed by MTU’s technical support, the service and the reliability of the MTU engines, which is why we will also be equipping our new Robert Allen/ Rastar 2900sx tugs with MTU engines.” Knut Müller, Head of the Marine and Government Business Division at MTU, said: “This is the first time high-speed engines are being used to power harbour tugs in this power class. To date, it has only been possible to use medium-speed engines for harbour tugs with a bollard pull of over 85t. We are delighted that we have now been successful in entering this market.” The speed of the engine has been reduced to 1850rpm specifically for this application in order to provide the Shipyards with direct control of the propeller without an intermediate gearbox. 6
The Robert Allen/ Rastar 2900 SX terminal tugs, with a length of just under 30m, will be added to the fleet operated by the Danish towage company Svitzer as of 2018. The tugs are to be used in the Tanger-Med Port in Morocco, the operators of which have now signed a 20-year contract with Svitzer for terminal towage services. The port is strategically located on the north-west coast of Africa, close to the entrance to the Mediterranean on the Strait of Gibraltar, and is the second busiest container port on the African continent. MTU and Sanmar have signed an additional contract for the delivery of four 16V 4000 M63 engines, each delivering 2000kW of power for two tugs with a 70t bollard pull. These new contracts now bring the number of tugs built by Sanmar to date and fitted with MTU engines to 16. Half of the tug types currently available from Sanmar Shipyards are fitted with MTU engines. VOLVO PENTA’S MOST POWERFUL ENGINE An exciting milestone has been reached for Volvo Penta, with its new 1000hp 13l engine, especially for owners of large yachts, who will now be able to benefit from better propulsion performance. The new D13-1000 sees Volvo Penta move into the 1000hp marine leisure engine market for the first time, and provides higher performance, greater durability and more comfort than ever before. The inboard engine and its equivalent from Volvo Penta’s Inboard Performance System (IPS) range – the D13-IPS1350 – have been designed for the benefit of customers operating yachts of up to 120ft. “This is hugely exciting for us to create our most powerful engine yet,” says Johan Wästeräng, vice president for product management in the marine leisure segment at Volvo Penta. “It’s truly a landmark product for our marine range, and really gives us a bigger step into the large yacht market. We’ve spent a long time talking to customers about what they want, and refining our engine and IPS designs, so that we can offer unique experiences with exceptional products that are ideal for world-class vessels.” As a mark of its commitment to the marine leisure industry, Volvo Penta has carried out a major redesign of the 13-litre engine model and drivetrain in order to offer an outstanding new product. High-end yacht customers will be able to reap the benefits, as features such as new pistons, highly efficient injectors and improved cooling systems, combine to produce 11 per cent more power than on previous engines. The optimised power-to-weight ratio and excellent low-end torque of the D13-1000 provide incredible power on demand. With this new engine, Volvo Penta is giving premium yacht owners the possibility to go further and faster than ever before. Volvo Penta’s D13-IPS1350 is an integrated package that matches the new D13 engine with an upgraded IPS pod drive. Upgrades to the IPS pod drive have been made to match the new engine. The D13-IPS1350 package is available in twin, triple or quadruple installation; the latter of these provides power to the equivalent of 5400hp. Improved features on the new IPS drive can also be fitted on existing IPS units. “The IPS drive has been upgraded so that it can handle the extra performance from the new D13 engine,” says Björn Rönnvall, product manager for the marine leisure segment at Volvo Penta. “We have found that there is a demand for greater durability with bigger yachts as the captain has to cruise to wherever the owner wants it to be, so the usage is higher. Increased low-end torque gives the vessel greater manoeuvrability at low speeds, and with the compact configuration this means there is more room on board for the luxuries that high end yacht owners want. IPS gives versatility and more freedom of design and performance – it really is the ultimate choice for large yachts.” “With 36 per cent better fuel economy this means that our IPS package has a much greater cruising range than a typical inboard engine,” says Rönnvall. “To put that into context, customers would be able to cruise from Cannes to the Balearic Islands without having to refuel in Spain, or from Miami to the Bahamas and back again on one tank of fuel.” 7
