Tech-Hub HANSA TECH-HUB KONINKLIJKE NIESTERN SANDER AG Ems converts Borkum ferry to LNG Car ferry »Münsterland« of Reederei AG Ems is converted for the use of LNG. The order went to Dutch shipyard Koninklijke Niestern Sander in Delfzijl. »Münsterland« is the third ship in AG Ems’ fleet to run on natural gas, already. In contrast to the first two projects, the German federal government has for the first time promised support for the conversion. The shipping company is relying on a conversion concept that has already been applied to the ferry »Ostfriesland«: While the ship is still operating, the shipyard is already building the new stern ship, including the LNG systems, thus reducing downtime to a minimum. The slightly adapted engine concept is based on a diesel-gas-electric system (dual fuel) with 360° rotatable electric pods. After the conversion, CO2 emissions will be reduced by 20% and nitrogen and sulphur oxides by as much as 90% and more. Fine dust is even almost completely being avoided. LLOYD’S REGISTER, CHINA CLASSIFICATION SOCIETY, GTT Joint industry project develops 220 k LNG carrier witk Mark III tank Lloyd’s Register (LR) has signed an agreement with COSCO Shipping LNG Investment, COSCO Shipping Heavy Industry Co., Jiangnan Shipyard, Marine Design and Research Institute of China (MARIC), Shanghai Ship and Shipping Research Institute (SSSRI) and China Classification Society (CCS) to design and develop the first 220 k LNG carrier with a GTT Mark III membrane containment system. The seven parties will define technical specifications and general arrangement of the main systems, to factor in route and capacity requirements. LR and CCS will provide technical support and consultancy services to ensure that the design meets all international regulations, industry-wide conventions and standards, and that it complies with each society’s classification rules. LR and CCS will also offer technical support for ship-shore matching, focusing particularly at upstream and downstream loading and unloading terminals. Once the LNG carrier has been designed, LR and CCS will look to grant the design approval in principle. The parties will conduct hydrodynamic assessments on the design to optimise its performance and plan to continually improve the design. • Drahtseile • Tauwerk • Festmacher • CASAR Bordkranseile • Anschlagmittel • Prüflasttest bis 1.000 t • Segelmacherei • Taklerei • Montage Walter Hering KG Porgesring 25 22113 Hamburg Telefon: 040 – 73 61 72 -0 eMail: info@seil-hering.de www.seil-hering.de VAN OORD Next efficient new hopper ordered Van Oord has decided to use the option for a third trailing suction hopper dredger at Keppel FELS. The vessel is similar to the two units ordered in May 2018. Each one has a hopper capacity of approx. 10,500 m3. The new hoppers will replace existing vessels and fit in with Van Oord’s aim of making its fleet more energy efficient. The climate control system on board will utilise the vessel’s cooling and heating sources to recycle energy. The ship’s automated systems will be more advanced than ever before, and integrated vessel data is being processed by a shore support centre. The vessels will obtain a Green Passport and Clean Ship Notation. The first two vessels, Vox Ariane and Vox Apolonia, will be delivered in 2021. The third vessel will be delivered in 2022. 66 HANSA International Maritime Journal 08 | 2019
Tech-Hub WÄRTSILÄ Hybrid solution for bulkers Technology group Wärtsilä has achieved what is called »a new technology benchmark« with the introduction of the marine sector’s first hybrid installation for a bulk carrier. This innovative system will be installed on the »Paolo Topic«, a bulk carrier built at Onomichi Dockyard in Japan and managed by Marfin Management. Wärtsilä’s hybrid power module, the Wärtsilä HY, will ensure the seamless integration and control of the technologies to be installed, with the ship’s various existing power generation systems. This is made possible by the use of a dedicated Energy Management System (EMS) that will have overall control of the engines, batteries, power distribution and – for the first time in the maritime industry – solar panels to be installed on the weather deck. The integrated solution is expected to deliver a drastic reduction in fuel consumption and maintenance costs. NIPPON PAINT MARINE Reflective coating saves energy White paint doesn’t look clean for long. Yet ship coatings of a darker hue absorb more heat, increase the heating, ventilation, and air conditioning (HVAC) requirement and, consequently, electrical load, resulting in higher fuel consumption and emissions. Introduced to the market following extensive shipboard trials, Nippon Paint Marine’s Ever Cool is specially formulated to reduce the effect of the Sun’s infrared rays on ship operations. The temperature difference between, for example, a deck coated with conventional paint system and one with Ever Cool can be up to about 28°C, with the specially formulated coating reflecting up to 80% of the Sun’s heat from coloured coatings. Requiring no special application tools or processes, Nippon Paint Marine uses advanced formulated reflective pigments to prevent surface temperature increases and lower heat transfer through steal plate and other structures. During tests on the compass deck of a Panamax bulk carrier, heat sensors recorded a surface temperature of 70°C on conventionally coated areas and 42°C on areas applied with Ever Cool. By reducing the surface temperatures of exposed decks, shipbuilders can reduce the insulation requirement, while ship operators can reduce the air conditioning/chiller load, saving fuel and improving the onboard conditions for passengers and crew, especially in tropical climates. In addition to decks, the heat resistant coating can also be applied to the topside of ballast water and cargo tank. The technology is also applicable to LNG insulated tanks to lower boil-off gases. VOLVO PENTA | ABB Buses as models for fast charging-at-sea Volvo Penta has announced that it is about to complete a feasibility study together with ABB and Chalmers University of Technology in Gothenburg to evaluate technology concepts that can meet the challenge of providing fast charging of electric vessels. Upon completion of the feasibility study, it is envisaged that the fast charging technology will be incorporated into Gothenburg’s Marine Demo Arena and become part of the ElectriCity public transport network. The research team does not have to start from scratch, thanks to the pioneering work of other business areas of the Volvo Group. Volvo Buses – again in collaboration with organizations such as ABB, Chalmers University of Technology and City of Gothenburg – has developed a fast charging network to support its two electric bus routes in the city. The feasibility study will assess if similar technology could be adapted for marine applications. The project has a clear ambition that the final technology will be open source, helping to speed up the adoption globally. HANSA International Maritime Journal 08 | 2019 67
