DNV GL ANNOUNCES NEW EMISSION REDUCTION NOTATION As the shipping industry continues its push to reduce emissions to air, classification society DNV GL has announced a new class notation for exhaust gas cleaning systems (EGCS). The new notation, Emission reduction (ER), will cover not only scrubbers for removing SOx, but selective catalytic reduction (SCR) and exhaust gas recirculation (EGR) systems for removing NOx. The new notation will be published in July 2018. “As the 2020 IMO sulphur cap on fuel draws closer, we have been hearing more and more from ship owners and operators who are looking for guidance on the installation and approval of systems which reduce emissions to air,” says Knut Ørbeck-Nilssen, CEO of DNV GL – Maritime. “Therefore, we are very pleased to be able to offer the Emission reduction notation to our customers. This notation will enhance the transparency of the installation and approval process for owners, the yards, and class, and give owners the confidence to invest in these systems.” DNV GL believes that interest in installing emission reductions systems, especially scrubbers, has risen dramatically in recent months. In May 2018, the total number of vessels either ordered or installed with scrubbers stood at 817, a jump of nearly 300 vessels in a space of only a few months. “This increase is due to several factors, but the trend is clear,” says Stine Mundal, Head of Section for Environmental Certification at DNV GL – Maritime. “At the same time, we are seeing that bulk and container vessels are the segments with the most installations, overtaking cruise vessels which had been the early adopters. This indicates that owners are making their solution decisions now and many are choosing scrubbers to comply with emissions restrictions.” The class notation sets out requirements for the design and arrangement of EGCS, SCR and EGR systems, including the piping systems conveying wash water and/or treatment fluids, the exhaust arrangements and components, control, monitoring and safety systems as well as manufacture, workmanship and testing. The ER class notation is a natural complement to DNV GL’s Scrubber ready notation, released in 2016, which enabled shipowners to prepare their newbuildings for the installation of a scrubber, giving them confidence that they were prepared for a smooth and cost-efficient scrubber retrofit. With ER, shipowners can now have the same confidence in the installation and operation of their new emission reduction systems. NEW ADVANCED COMPACT SCRUBBER LAUNCHED FOR LARGE SHIPS Mitsubushi Shipbuilding and Mitsubishi Hitachi Power Systems (MHPS) have combined to launch an advanced exhaust gas cleaning system (scrubber) targeting larger ships. The new scrubber, known as the Active Funnel, is said to be suitable for very large container ships with high exhaust gas emissions and limited installation space for SOx abatement systems. According to the joint developers, the scrubber contains an optimally-shaped exhaust gas scrubbing structure which is said to reduce sulphur dioxide in the exhaust gas of 3.5% sulphur content fuels to 0.1%, enabling ships to comply with .the IMO fuel sulphur emissions restrictions coming into force in 2020 while still burning cheap high-sulphur fuel oils. The new system combines MHPS’s exhaust gas treatment technologies, developed through providing desulphurisation systems for thermal power plants, with Mitsubishi Shipbuilding's marine engineering expertise. MHPS points to the example of its landbased flue gas desulphurisation systems which have the capacity to treat the equivalent of seven to 20 times of the emissions from a large size marine diesel engine. The solution is said to desulphurise large amounts of exhaust gas and its flexible design makes installation possible even in narrow spaces between the container holds, while maintaining a vessel's container capacity. Mitsubishi Shipbuilding and MHPS say the Active Funnel, which is applicable to both open-loop systems and hybrid systems, is suitable for installation on existing ships since it is provided as one module and has a short retrofitting period. 10
WILHEMSEN AND WÄRTSILÄ SIGN SCRUBBER SERVICE AGREEMENT Wärtsilä and Norwegian Wilhelmsen Ship Management, a Wilhelmsen group company, have signed a 5-year agreement covering the maintenance of exhaust gas cleaning systems installed in three vessels managed by Wilhelmsen Ship Management. The agreement ensures that the vessels are fully MARPOL compliant and can fulfil the IMO’s new, stricter sulphur limits, coming into force on 1 January 2020. All three vessels have a 25MW Wärtsilä Hybrid Scrubber System, which has the flexibility to operate in both open and closed loop, using seawater to remove SOx from the exhaust gas. In closed loop mode additional reagent is used in combination with sea water. The services covered under this agreement include annual audits and safety tests to ensure ongoing MARPOL compliance, calibration of the Continuous Emission Monitoring System (CEMS) and water monitoring system as well as operational training courses for the vessels’ crew. “For Wilhelmsen Ship Management, operating sustainably and maintaining MARPOL compliance is absolutely crucial. This agreement with Wärtsilä ensures that we are doing it in a correct and documented way to fulfil authorities’ requirements. Additionally, it allows us to perform long term cost predictability and channel more focus into critical ship management operations,” said Jon Helge Ulstein, Vessel Manager at Wilhelmsen Ship Management. “Wärtsilä’s purpose is to enable sustainable societies with smart technologies. We want to build awareness of sustainability and provide solutions that help customers reduce or eliminate emissions. This agreement with Wilhelmsen Ship Management does exactly that by ensuring that the vessels comply with the strict sulphurs limits set by IMO’s standards. Additionally, the agreement provides Wilhelmsen Ship Management with predictability of the vessel maintenance costs,” said Glenn Holid, Sales Manager at Wärtsilä Moss. Wilhelmsen Ship Management is one of the largest third-party ship managers with a portfolio of more than 450 vessels and 9,200 active seafarers. Wilhelmsen Ship Management manages its portfolio from five offices worldwide and has a crewing network of 18 manning offices in 12 countries. As defined in IMO’s regulations, the global limit for sulphur in fuel oil used by ships will be reduced from the current 3.50% m/m (mass by mass) to only 0.50% m/m on and after 1 January 2020. FUEL DIESEL ENGINE FUEL EFFICIENCY OPTIMISED WITH HYDROGEN MIX FuelSave, a German fuel and emissions start-up, has launched a ground-breaking technology capable of optimising the fuel consumption efficiency of all marine diesel engines. The technology, proven in both in-the-field and laboratory tests, is claimed to offer a contractually guaranteed 10% saving on overall fuel costs, while significantly reducing CO2 emissions. FS MARINE+, a patented technology that could see ship operators profit with a threeyear return on investment, is an engine efficiency enhancement solution that uses an onboard hydrogen syngas generator to inject a gas and liquid water methanol mix into the combustion process, thus significantly improving efficiency. The system, approved by DNV GL, can be retrofitted to any vessel and achieves compliance with IMO tier I and II for older ships. Engine maintenance costs can also be slashed since FuelSave says the process makes for a cleaner engine, a cleaner combustion process, greater lubrication efficiency and reduced vibration. This was demonstrated during a 30- month pilot application onboard a European-owned heavy lift ship. Results from these trials verified the performance of FS MARINE+ through independent analysis and reports from engine service and maintenance companies, as well as from a university testing institute. The solution has also received approvals from a number of certification bodies. 11
