A new IMO resolution will see the phase-out of foam firefighting systems that use fluorinated foams containing perfluoro-octane sulfonic acid (PFOS) as the foam-producing component. The new rules come into effect under a rolling programme beginning in 2026, but Swedish maritime engineering specialist Scanunit believes that a proactive replacement strategy should be put into effect now.Foam firefighting systems on ships typically make use of a family of synthetic chemical compounds known as perfluoroalkyl and polyfluoroalkyl substances (PFAS).

Neste is partnering with PTL Marine to provide Neste MY Renewable Diesel to the marine sector across the State of California.California’s Commercial Harbor Craft (CHC) regulation, established by the California Air Resources Board (CARB), took effect on January 1, 2023. This regulation requires commercial harbor craft vessels in the state to use renewable diesel (also known locally as R99 or R100) instead of ultra-low sulphur diesel (ULSD), to limit emissions such as particulate matter and nitrogen oxides for vessels operating in the state’s ports and near the coast.

The U.S. Navy has many assets other than its seaborn vessels to care for, and recently it adopted new standards to protect those that are fuel-related. Naval Facilities Engineering Command (NAVFAC) contracted with Master Painter Institute (MPI) services to establish product standards for interior carbon-steel fuel pipes, interior welded fuel tanks, exterior steel systems and waterfront steel structures. These new standards, known as the MPI 500 Series Standards, are for use in numerous aspects of work involving specialized Department of Defense (DoD) petroleum…

Researchers looking for an ecologically and economically sustainable way to replace fossil fuels are exploring how suitable fuel oils made from biomass and waste plastics are for power plants and ship diesel engines.Internal-combustion engine power plants use natural gas or heavy fuel oil in diesel engines. In order for large diesel engines to be environmentally sustainable both on land and at sea, it is necessary to find bio- and waste-based alternatives to fossil fuels. These…

Swedegas Renewable Gas Bunkering at Gothenburg Port

Swedegas, the owner of the gas grid in Sweden, conducted the first liquefied natural gas (LNG) bunkering operation at its new facility at the Port of Gothenburg.Gothenburg-based shipping company Terntank was the very first operator to take on  LNG at a new bunkering facility, said the Swedish owner and operator of the high-pressure gas grid.Not only liquefied natural gas, LNG, but also liquefied biogas, LBG, it added.“Being able to offer this unique opportunity represents a major breakthrough, not only in facilitating the transition to LNG, but also in gradually increasing the proportion of renewable gas,” said Johan Zettergren, Chief Executive of Swedegas, which owns and runs the facility.The facility is the only one of its kind in Sweden, it claimed.

NASA May Send Submarine to Titan

NASA has unveiled plans to send a submarine into the depths of the largest ocean of Saturn's biggest moon, Titan in a bid to explore the depths of its largest ocean. The aim to find the chemical composition of the largest ocean of the moon, Kraken Mare and search for signs of life. Jason Hartwig, a NASA cryogenics engineer has disclosed the idea while he was giving a presentation at NASA Innovative Advanced Concepts Symposium in Raleigh, reports inverse.com. "There are really two big reasons why we want to go to Titan. Number one: to determine if hydrocarbon based life is possible on Titan," he said. Number two: as the only moon in our solar system with clouds and an atmosphere, Titan is very similar to Earth — apart from the extreme cold and oceans of liquid methane.

Lithuania Puts Plans to Import LNG From US On Hold

Lithuania has put plans to buy liquefied natural gas from the United States on hold because the LNG is not yet suitable for the Baltic state's gas system, its state energy company said on Wednesday. Lithuania's system was built to use Russian gas and state energy group Lietuvos Energija said U.S. LNG was much more calorific than Russian gas. The country opened an LNG import terminal in the Baltic Sea at the end of 2014, which allowed it to start importing from Norway and end its total dependence on gas imports from its former Soviet master, Russia. "We are not buying gas from the U.S. at the moment, because the gas they are offering at the moment does not meet specifications needed for our gas distribution system," Ernesta Dapkiene, a spokeswoman for Lietuvos Energija, told Reuters.

Bunker Fuel Market Poised 460 million tons by 2020

Transparency Market Research launched its latest study on the global bunker fuel market, in terms of revenue and volume. The report predicts that the global bunker fuel market is likely to reach an estimated volume of 460 million tons by 2020. The market, therefore, is poised to exhibit a moderate 3.1% CAGR during 2014-2020, expanding from 372.30 million tons in 2013. Bunker fuel is a fractionally distilled liquid fuel derived from crude oil. Also known as fuel oil, the substance can be classified on the basis of its chemical composition, intended purpose, and boiling point. Unlike other petroleum products, bunker fuel is more polluting and highly unrefined. Apart from fuel oil, there are other middle distillate fuels, which are also used as bunker fuels.

A Bundle of Advanced Technology

The close cooperation of the Finnish Maritime industry is evidenced in the highly capable icebreaking ships that it produces. Icebreakers are essential to Finland’s existence, as the specialized ships enable the country to keep its shipping lanes operational during the harshest winter months. However, traditional icebreaker design made for poor navigating vessels in open water, and thus were rendered useful during only the winter months. This was acceptable, but very expensive, as icebreakers by nature represent a significant maintenance challenge and cost. The solution: creating a new design icebreaker that could be used, profitably, year-round.

Aluminum Gone "Bad"

There has been a lot of discussion in the marine industry over the past year with regard to "bad" aluminum. To briefly recap, a number of boat builders purchased aluminum from a supplier that met the requirements of ASTM 5083 H321. This alloy is accepted by both Lloyds Register (Lloyds) and Det Norske Veritas (DNV) for building aluminum vessels. After the aluminum was used to construct some vessels, the operators began to observe surface pitting corrosion. Upon investigation, it was discovered that the purchased plate had been treated differently during manufacturing, with the result that manganese nodules were precipitating out of the alloy, thus making it susceptible to inter-granular corrosion. The result was that newly-built vessels had to be rebuilt and their original hulls scrapped.
