ABS-LED RESEARCH IDENTIFIES KEY EAL EVALUATION REQUIREMENTS ABS, in partnership with Vickers Oil and Imperial College London, has completed a joint study on the use of environmentally acceptable lubricants (EALs) on stern tube bearings. The study evaluated EAL properties relative to mineral oil-based lubricants and concluded oil viscosity is the primary property in selecting an EAL. “Interest in EAL performance has grown following an increase in the number of new build stern tube bearing failures in 2014,” said Derek Novak, ABS Senior VP of Global Engineering and Technology. “Working closely with our project partners in an extensive study of EAL properties, we found oil viscosity is the main determinant in choosing the optimal EAL for normally operating stern tube bearing installations.” Primarily driven by US EPA requirements put in place in 2013, EALs were intended to replace mineral oil lubricants in marine vessels. During this joint project, ABS and its partners identified, through experimental research, key characteristics of EALs compared to mineral oil lubricants: ■ Viscosity of EALs is more stable than that of mineral oils, with respect to changes in temperature ■ EALs demonstrated relatively lower pressure-viscosity coefficients than mineral oils, indicating EALs may form thinner oil films, potentially insufficient to protect surfaces from wear under edge loading conditions ■ Using EALs with higher pressureviscosity coefficients, compared to other EALs of the same viscosity, may provide some safety margin in shaftalignment sensitive installations ■ EALs may offer less margin in shaft misalignment conditions, therefore particular attention should be taken for correct shaft alignment ■ Using EALs with higher viscosity, compared to a mineral oil of lower viscosity, may provide additional tolerance for edge loading wear. “The results of this study offer important insights into both viscosity selection and the more specialized area of pressure-viscosity coefficient behaviour, where no universally-adopted measurement standard exists,” said Vickers Oil Technical Director, Chris Wholley. “By tackling this issue together with ABS and Imperial College London, we were able to develop a deeper understanding of lubricant behaviour in a journal bearing, operating both normally and under edge loading conditions, which will help us to give the best advice to owners and operators wishing to reduce the adverse effects of shaft misalignment, and inform our product development process.” SAVE MILLIONS IN DRYDOCK COSTS AND OFF-HIRE TIME Hull of cruise ship after 5 years with Ecospeed coating with no replacement or major repair. This is the state of the hull when the ship came out of the water, without any cleaning or touch-up in drydock. When your hull coating never needs replacing or major repair, you can save a lot of money in drydock fees, offhire time, materials and labour. Most hull topcoats are designed to be replaced once or twice every five years. The full hull coating scheme has to be fully replaced every 10 - 15 years down to bare steel. Over that time period, the coating degrades and becomes rougher until it’s no longer worth trying to patch it up. And it costs you a fortune in fuel to compensate for the additional hull friction. Imagine a coating that’s guaranteed for 10 years and is expected to last 25 without replacement or major repair. A coating that gets smoother over time, not rougher! Imagine coming into drydock after 3 or 5 years and finding that your hull coating only requires a few minor touch-ups and doesn’t even need to be washed off. Call us today for a quote to convert your hull to Ecospeed or start off right, with Ecospeed, on a new build.

WÄRTSILÄ TO MAINTAIN LNG FUEL SYSTEM FOR VIKING GRACE Wärtsilä and Viking Line have signed an Optimised Maintenance agreement for the Wärtsilä LNGPac system onboard passenger ferry Viking Grace. This is the first Optimised Maintenance agreement made for Wärtsilä LNGPac, a complete gas handling system for ships fuelled by liquefied natural gas (LNG). Viking Grace was the first passenger ferry to use LNG as a fuel source. The agreement includes Condition Based Maintenance (CBM) and online support for the LNGPac system. Additionally, Wärtsilä extends its existing Optimised Maintenance agreement, signed in late 2017, for Viking Grace for another five years. The agreement enables the planning and scheduling of Viking Grace’s maintenance procedures to suit the shipowner’s business operations, thus improving longterm cost predictability. It also increases performance reliability and maximises the vessel’s uptime. A new feature for the LNGPac agreement is Wärtsilä’s CBM system that gathers information on the average gas flow, the temperatures of the heat exchangers, the use of energy, and the pressure of the LNG pumps. The data helps in planning and scheduling the above-mentioned maintenance procedures that improve cost predictability and uptime. Wärtsilä LNGPac is a complete fuel gas handling system for LNG fuelled ships. On Viking Grace, it comprises onboard liquid natural gas bunkering, two storage tanks, and handling equipment with related safety and automation systems that have been developed by Wärtsilä. “Environmental considerations are, along with the need to optimise operational efficiency, high on the agenda of Viking Line,” says Ulf Hagström, Senior Vice President, Marine Operations & NB at Viking Line Oyj. “Wärtsilä is a forerunner in dualfuel and other environmentallysound technology and has repeatedly shown its excellence in technical assistance and service for LOW-EMISSION SHIP PROJECT SEEKS MORE PARTICIPANTS Eco Marine Power (EMP) of Japan has unveiled its plan to widen the scope of the Aquarius Eco Ship project and invite other companies to join this low-emissions ship design initiative. As part of this plan, a wider range of technologies will be studied including fuel cells, air lubrication systems & electrical propulsion. The centre piece of the Aquarius Eco Ship is Aquarius MRE - a patented fuel saving and emission reduction system that incorporates a variety of elements including solar panels, energy storage modules, computer control systems and an advanced rigid sail design known as the EnergySail. Elements of Aquarius MRE have already been commercialised and it is expected that the expanded project will lead to further fuel and emission reduction solutions being introduced into the market. EMP Viking Line and Viking Grace. With this agreement, we will be able to utilise the full potential of Wärtsilä’s knowledge and know-how.” In addition to Wärtsilä LNGPac, Wärtsilä has delivered four Wärtsilä 50DF main engines running on LNG, the transverse bow and stern tunnel thrusters, two stainless steel fixed pitch, built-up main propellers with complete propeller shaft lines and environmentally sound shaft line seal systems to Viking Grace. Since Viking Grace was taken into operation in 2013, Wärtsilä has been in charge of its maintenance. The vessel can accommodate 2,800 passengers, and it sails between Turku, Finland and Stockholm, Sweden in the Baltic Sea. recently displayed several technologies associated with the project including a working prototype of an EnergySail and the EnergySail Automated Control System (ACS) at Sea Japan 2018 in Tokyo. Greg Atkinson, Chief Technology Officer at Eco Marine Power commented; "A primary aim of opening up and widening the Aquarius Eco Ship project is to help develop further practical fuel and emission reduction technologies beyond our current focus on wind & solar power. We also wish to extend the project's reach further outside Japan and bring in additional investors so that we can help other startups in the maritime clean technology field." Companies already involved in the Aquarius Eco Ship Project include Teramoto Iron Works, The Furukawa Battery Company and KEI System. 9
