Engine designer has prioritized collaboration and transparency in its new cylinder lubrication guide, to ensure that selecting the right oil is easier than ever. For the first time, the new documentation provides ship operators with consolidated, at-a-glance information highlighting the specific usage conditions for each and every approved cylinder oil.

The guidance is the result of several months’ work with major oil companies to make usage requirements more transparent. Previously, the guidelines for each oil were found only in the industry standard No Objection Letters issued by WinGD to oil companies, and available only upon request by a customer to an oil company directly. Now this information has been included in the full list of approved cylinder oils.

To find an appropriate cylinder oil, users first select a suitable Base Number range based on their fuel sulphur content. Customers then look through the guide to see which oil products fall within a specified BN range. The document then highlights whether each oil is approved for general, long-term use or whether further stipulations – such as a time limit or greater frequency of inspections – are required. An additional category, labelled as ‘DF validated’ shows whether the oil has passed a validation trial while burning gas as the predominant fuel during that trial.

“Cylinder oil is not just another consumable onboard – it’s considered an important engine component that ensures reliable operation,” says Frank Venter, WinGD Project Engineer Tribology Fuels & Lubricants.  “Given the already wide variability in existing fuels available, it is important that engine companies and oil suppliers work together to offer clarity for ship operators about which oils can be used and how. This will become increasingly important as we embrace a decarbonised future with potentially multiple varied sources of both liquid and gaseous fuels.”

The development follows extensive work with oil majors in the run up to 2020 to ensure that cylinder oils could meet the challenges of new fuel types. The engine designer’s well-established validation procedure has identified many cylinder oils with a broad spectrum of properties (including BN) which are fit for operation with both low and high-sulphur fuels as well as for gas fuel operation.

The correct use of appropriate cylinder oil completes WinGD’s robust and well-proven tribological design concept. Its engines feature state-of-the-art cylinder lubrication systems combined with unique cylinder liner, piston and piston ring designs. These improve reliability and enable a long time between overhaul for combustion chamber components, ultimately resulting in more predictable and lower cost engine maintenance.

ADNOC, announced that it has begun construction on the Middle East’s first high-speed hydrogen refueling station. The station, which is being built in Masdar City by ADNOC, will create clean hydrogen from water, using an electrolyser powered by clean grid electricity.

Hydrogen, which creates no carbon dioxide emissions when used, has the highest energy per mass of any fuel and can give vehicles a longer driving range and quicker refueling times compared with battery electric vehicles.

ADNOC also announced a partnership with Toyota Motor Corporation and Al-Futtaim Motors to test the high-speed hydrogen refueling station using a fleet of clean hydrogen-powered vehicles.

His Excellency Dr. Sultan Ahmed Al Jaber, Minister of Industry and Advanced Technology and ADNOC Managing Director and Group CEO, said: “The need to reduce carbon emissions to address climate change is clear and urgent. ADNOC is placing sustainability and decarbonization at the heart of its strategy and, while we decarbonize our operations today, we are making robust investments to be a supplier of choice for the clean energies of tomorrow.

“Hydrogen will be a critical fuel for the energy transition, helping to decarbonize economies at scale, and it is a natural extension of our core business. Through this pilot program, we will gather important data on how hydrogen transportation technology performs as we continue to develop the UAE’s hydrogen infrastructure.”

Under the partnership, Toyota and Al Futtaim Motors will provide a fleet of hydrogen-powered vehicles. The pilot program will help ADNOC understand how hydrogen with high-speed refueling can best be used in mobility projects to support the UAE’s National Hydrogen Strategy, which aims to position the country among the largest producers of hydrogen by 2031.

ADNOC Distribution will operate the station upon its completion later this year. A second station, in Dubai Golf City, will be fitted with a conventional hydrogen fueling system.

ADNOC has allocated $15 billion (AED55 billion) to advance and accelerate lower-carbon solutions, investing in new energies and decarbonization technologies to reduce its carbon intensity by 25% by 2030 and enable its Net Zero by 2050 ambition.

NYK announces the order of its sixth liquefied petroleum gas dual-fuel very large LPG / liquefied ammonia gas carrier from Kawasaki Heavy Industries Ltd. The ship will be built at the KHI Sakaide Works shipyard and is set for delivery in 2026.

This vessel is the eighth in NYK’s fleet of LPG-fueled LPG carriers and the sixth in a new type of vessel capable of carrying ammonia and thus flexibly responding to various trade patterns.

Furthermore, in addition to the LPG dual-fuel engine, the ship will have a shaft generator that can generate electricity during the voyage by using the rotation of the shaft that connects the main engine to the propeller. Since the diesel generator can be stopped during regular seagoing transit, realizing full navigation with LPG fuel will be possible except for the use of a small amount of pilot fuel as an ignition source.

When LPG is used as fuel, exhaust gas from the ordered VLGC will contain at least 95% less sulfur oxide and 20% less CO2 than NYK’s conventional VLGCs using heavy-oil fired engines.

This new VLGC will comply not only with the SOx Global Cap regulations* that were tightened from January 2020 but also with the IMO’s Energy Efficiency Design Index Phase 3 regulations, which implemented stricter CO2 emission standards from April 2022.

Moreover, the vessel is expected to be given notations by Nippon Kaiji Kyokai  as a VLGC that has a preparatory design in accordance with the guidelines issued by ClassNK so that this vessel may use ammonia fuel in the future.

Vessel Particulars

Length overall: approx. 230 meters
Breadth (moulded): 37.20 meters
Depth (moulded): 21.90 meters
Summer draft (moulded): 11.65 meters
Tank capacity: approx. 86,700 cubic meters

NYK supplies biodiesel fuel to the wood-chip carrier Daio Austral

NYK supplied biodiesel fuel at Kinuura port to the wood-chip carrier Daio Austral, which transports wood chips for Daio Paper Corporation. This was the first oceangoing vessel operated by NYK to receive biodiesel fuel in Japan. The ship then made a test voyage to Cai Lan port in Vietnam, arriving safely on June 29 local time.

Toyota Tsusho Marine Fuel Corporation supplied the biofuel, and while sailing, the ship verified the main engine and generator conditions when using the biofuel.

Biofuels are considered to be carbon-neutral because the carbon dioxide that is absorbed by the source of the biomass is equal to the carbon dioxide that is released when the fuel is burned. Since biofuels can also be used in heavy oil–fired engines, they are considered to be a powerful means of reducing greenhouse gas (GHG) emissions during the transition from heavy oil to zero-emission fuels.

From fiscal 2019 to fiscal 2022, the NYK Group successfully conducted test voyages using biofuels on seven oceangoing vessels, mainly bulk carriers and two tugboats. In fiscal 2023, the NYK Group aims to conduct test voyages on multiple ships, and this trial was completed with the cooperation of Daio Paper Corporation.

NYK will continue to actively introduce biofuels and other next-generation fuels to promote decarbonization in marine transportation.
