  IMO MEPC will meet for its 68th session next week, from 11 to 15 May 2015, at IMO Headquarters in London.  The hot issue on the agenda will be the adoption of the draft environmental provisions of the Polar Code which will make the Code mandatory. The adoption of the Polar Code and associated MARPOL amendments at MEPC 68 will complete the process to make the Code mandatory under both the SOLAS and MARPOL treaties.   Other items under discussion at the forthcoming meeting will be as follows: MARPOL Annex I amendments relating to oil residues set for adoption  The MEPC will consider, with a view to adoption, draft amendments to regulation 12 of MARPOL Annex I, concerning tanks for oil residues (sludge).  The draft amendments update and revise the regulation, expanding on the requirements for discharge connections and piping to ensure oil residues are properly disposed of.  A related revised unified interpretation to the regulation will also be put forward for adoption.   Ballast water management status and technologies to be reviewed The MEPC will review the status of the International Convention for the Control and Management of Ships' Ballast Water and Sediments (BWM Convention), 2004, which is ...

  The Marine Environment Protection Committee (MEPC) of the International Maritime Organization (IMO) meets for its 68th session from 11 to 15 May 2015, at IMO Headquarters in London.  Items on the agenda include the proposed adoption of the environmental part of the Polar Code and associated draft MARPOL amendments to make the Code mandatory; the implementation of the Ballast Water Management Convention; further work on air pollution and energy efficiency measures; and a proposal to extend the Great Barrier Reef and Torres Strait Particularly Sensitive Sea Area (PSSA) to parts of the Coral Sea. Polar Code environmental provisions set for adoption  The MEPC is expected to adopt the environmental requirements of the mandatory International Code for ships operating in polar waters (Polar Code), and the associated MARPOL amendments to make the Code mandatory. This follows the adoption, by the Maritime Safety Committee (MSC) in December 2014 of the Polar Code and related amendments to make it mandatory under the International Convention for the Safety of Life at Sea (SOLAS).  The Polar Code is expected to enter into force on 1 January 2017.   The Polar Code covers the full range of design, construction, equipment, operational, training, search and rescue ...

  The Wärtsilä 50DF marine engine has been successfully tested and certified to run on ethane (LEG) fuel. The extensive and successful testing programme was carried out by Wärtsilä in close collaboration with Evergas, a world renowned owner and operator of seaborne petrochemical and liquid gas transport vessels.  “We are very pleased that the Wärtsilä engines will be capable of utilising ethane boil-off gas as fuel. It increases our operational efficiency and improves flexibility in the bunkering of fuels. All in all it results in a significant reduction in operating costs, while also providing a minimal environmental footprint. It also enables us to offer our customers increased flexibility, which has a monetary value to them,” says Mr Steffen Jacobsen, the CEO of Evergas. The capability to efficiently burn ethane boil-off gas as engine fuel significantly reduces the need of gas re-liquefaction during the voyage. This means that less power is needed for the cargo handling, thus providing a more efficient and environmentally sound overall system. This technological breakthrough enables Wärtsilä´s customers to meet the International Maritime Organization’s (IMO) Tier III regulations without need of secondary emissions cleaning while using either LNG or LEG as fuel.  The engines have the capability ...

  At an awards ceremony held on 15 April, 2015 at the PrimeServ Academy in Shanghai, MAN Diesel & Turbo SE was awarded approval in principle for its SCR system for the entire medium-speed engine portfolio fulfilling IMO Tier III regulations by the China Classification Society (CCS). Testing took place on an MAN 8L21/31 auxiliary engine with an integrated SCR system but the certificate applies to the entire medium-speed engine portfolio . The MAN-built engine is bound for a DFDS Seaways Ro-Ro vessel, the ‘Petunia Seaways’. The ceremony was attended by major ship owner companies and licensees. Goetz Kassing, Chairman and Head of MDT China, received the certificate on behalf of MAN Diesel & Turbo from Sun Feng, Vice President of CCS. “This certificate represents an important milestone in our collaboration with CCS and is of utmost importance in providing a complete IMO Tier III package solution to our customers,” said Dr. Daniel Struckmeier – Head of Emission 2016 – Senior Project Manager, MAN Diesel & Turbo. “This milestone is one of three agreed major steps in a long-term relationship with CCS. The first step has been accomplished after issuance of the first IMO Tier III EIAPP certificate for the ...

  With key dates looming - 2016 NOx compliance and a 2018 review of fuel availability ahead of a global cap for SOx emissions, LR’s new guidelines and updated technical information supports operators’ investment decisions. This new guidance addresses operational and in-service considerations reflecting further accumulated experience from working closely with clients, industry groups and regulators. As well as a focus on exhaust gas treatment (scrubbers) the guidance also examines the wider scope of options for SOx/NOx compliance beyond exhaust gas treatment.  Since an earlier version of this report was issued in 2012, early adopters of the technology, mainly passenger ship and ferry operators,  have committed to fleet-wide scrubber implementation programmes. Early adopters gain valuable operational experience as well as a head start in both understanding the technology and realising any benefits. In the majority of the tanker, bulk carrier and container segments the uptake of scrubber technology remains slow. With shorter periods inside Emission Control Areas (ECAs), lower fuel consumption (especially due to slow steaming) and typically lower asset residual values, the business case for installing scrubber technology on deep sea tank, bulk or container ships is not, yet, either strong enough or urgent enough. The bunker price collapse during ...

  A new ship for Norwegian shipping firm Nor Lines has set the milestone in shipping history as the world’s first vessel to sail from Asia and Europe solely on liquefied natural gas (LNG). Kvitbjørn is a 5,000 DWT short sea cargo vessel built to Rolls-Royce’s award-winning Environship concept. The ship sailed to Norway from Tsuji Heavy Industries shipyard in Jiangsu, China, via Singapore, and subsequently LNG bunkerings in Cochin, India and Cartagena, Spain. This was the longest voyage ever undertaken by a vessel running solely on LNG and was completed in Bergen on 29 March. Tor Arne Borge, Nor Lines, CEO said: “The success of the voyage from Asia to Europe on LNG not only confirms the energy-saving and emissions-reduction attributes of Rolls-Royce’s pure gas engine but provides evidence to owners of larger tonnage that LNG is not just for short sea coastal ships. The Environship concept with the Bergen engine has exceeded all our expectations.” The Environship, which can be adapted for different ship types, incorporates a range of  Rolls-Royce technologies to deliver efficiency savings for ship owners. These include a Bergen engine powered by LNG, the Promas combined rudder and propeller, a hybrid shaft generator to optimise ...

Mitsubishi Heavy Industries Marine Machinery & Engine (MHI-MME) released UE Engine Technical Data on its website. The new Technical Data can be browsed and downloaded from the company's website. The new search system, which complies with IMO NOx Tier III regulations, is designed to provide a broad range of useful information to our customers planning new vessels with UE engine. Formerly, MHI-MME shared the UE Engine Technical Data which comply with IMO NOx Tier II regulations, with a limited number of customers on the dedicated website. However, in order to provide better user-friendliness, MHI-MME renewed the system for IMO NOx Tier III compatible engines by improving the format, contents or design, and released the data widely on the website. At this moment, the data for two engine types, UEC50LSH-Eco-C2 and UEC45LSE-Eco-B2, are released to the public. Furthermore, MHI-MME is planning to release the data for all UE Engines that are control subjects of the IMO NOx Tier III regulations, on the website by the end of 2016. Meanwhile, MHI-MME will continue to provide the Technical Data which comply the IMO NOx Tier II through the existing dedicated site. On the strength of this renewal of UE Technical Engine Site, MHI-MME ...

On 17 March, 2015 at MAN Diesel & Turbo’s Diesel Research Centre in Copenhagen, the company successfully demonstrated the ME-LGI concept in front of existing ME-LGI customers and partners, including Westfal-Larsen, Marinvest, Waterfront Shipping/Methanex, MES, HHI-EMD, MOL, and Minaminippon. For the purposes of the event, the company rebuilt its 50MX test engine to an ME-LGI unit. Vice President and Head of R&D, Søren H. Jensen, said: “Attendees showed great interest in the demonstration and the accompanying technical presentations; their feedback has been very positive.” He continued: “A number of years ago we identified the need to develop an engine that could run on more environmentally-friendly, competitively-priced fuels as an alternative to MDO/MGO. We believe the ability of the ME-LGI engine to run on sulphur-free fuels offers great potential. Methanol carriers have already operated at sea for many years. With a viable, convenient and economic fuel already on-board, exploiting a fraction of the cargo to power a vessel makes sense.” To date, MAN Diesel & Turbo has received orders for 7 × ME-LGI engines – a mixture of 7S50ME-LGI and 6G50ME-LGI variants – from Mitsui O.S.K. Lines, Marinvest and Westfal-Larsen. The very first engine will be produced by Mitsui Engineering & ...

  The first Wärtsilä two-stroke engine with a high pressure SCR (Selective Catalytic Reduction) system manufactured in China has been introduced. The system is fitted to a 5-cylinder Wärtsilä RT-flex58T-D 2-stroke, low speed engine produced at the Hudong Heavy Machinery Co Ltd (HHM) facilities. The SCR reactor was also manufactured by HHM. This is the first SCR system that complies with the IMO’s Tier III regulations for engine emissions of nitrogen oxide (NOx). The Wärtsilä engine with SCR is to be installed in a new 22,000 dwt multi-purpose vessel currently under construction at the Ouhua shipyard on behalf of China Navigation Co (CNCo). The ship, which is scheduled for delivery in the second quarter of this year, has been designed to allow sufficient space for the fitting of the SCR. This will enable the vessel to comply with the Tier III regulations for NOx control. The SCR system for this application has been jointly developed by HHM and Winterthur Gas & Diesel (WinGD), the joint venture company of Wärtsilä and China State Shipbuilding Company (CSSC), using a basic design concept from Wärtsilä which has been adapted to suit the particular requirements of the engine and ship. Wärtsilä has been producing ...

In connection with the recent announcement of the construction of three wetfish trawlers for HB Grandi, the Icelandic fishing concern, MAN Diesel & Turbo has announced that the newbuildings’ MAN main engines will also feature its SCR (Selective Catalytic Reduction) system. The company states that the system will enable the trawlers’ IMO Tier II-compliant engines to fulfil the strict IMO Tier III NOx emission requirements. Vilhjalmur Vilhjalmsson, CEO of HB Grandi said: “When we decided to renew our fresh-fish fleet, we immediately focused on the task of curtailing the ships’ power requirements, both in terms of the propulsion plant as well as electricity production, so as to make the exhaust gas as clean as possible.” Vilhjalmsson added that HB Grandi deliberately pursues a green company profile and that its focus on clean and responsible fishing ultimately led to MAN technology being chosen for the trawlers. As such, HB Grandi’s profile suited the minimal environmental footprint from operations, including the cleaner exhaust gasses and NOx reduction that the MAN package offers. A further advantage of choosing MAN was the relatively straightforward integration of engine, propeller, propulsion controls and SCR system that equipment from the same manufacturer entails. MAN Diesel & Turbo ...
