THE SHIP- AIR- SEA- INTERFACE As international maritime transport continues to increase (Smith et al., 2015), there is growing concern about its sustainability and environmental impacts, ranging from effects on marine ecosystems to human health. Approximately 80% of the fuel used in commercial shipping in 2007-2011 was low-grade, high-sulphur content fuel (Smith et al., 2015), which emits significant amounts of carbon dioxide (CO2), sulphur oxides (Sox), nitrogen oxides (NOx), aerosols [with particle matter (PM), containing organic carbon (OC), black carbon (BC), polycyclic hydrocarbons (PAHs), and heavy metals] to the atmosphere during combustion (Cooper and Gustafsson, 2004; Eyring et al., 2005). Some of these compounds have a limited residence time in the atmosphere, deposit relatively close to the source vessel and become dissolved or suspended in the surface ocean. In recent decades, global and regional efforts to reduce the environmental impact of ship emissions have been made. To reduce sulphur emissions from shipping, limits were included in international regulations adopted by the International Maritime Organization (IMO)1, such as Annex VI of the International Convention for the Prevention of Marine Pollution from Ships (MARPOL, 2017) and the European Union's Sulphur Directive (EU, 2016). International law treats the atmosphere and the ocean very differently, although they are tightly linked via chemical, physical, and biological processes. Emissions of gases and particulates to the atmosphere affect the surface ocean directly and indirectly through deposition and dissolution of gases, as well as via radiative forcing effects on the climate. Similarly, discharge of pollutants and contaminants to the ocean may reach the atmosphere by outgassing and aerosol production (the SOLAS Scientific Steering Committee, 2016) Several sulphur abatement techniques already exist including novel engine technologies, exhaust gas recirculation and fuel emulsifiers. Exhaust gas cleaning systems operating in open loop mode, referred to colloquially as “scrubbers,” are low-cost and therefore preferred alternatives to high-cost, low-sulphur fuel. Scrubber technology primarily removes Sox, from ships' exhaust, and NOx and particles to some degree, but not CO2. #mariners #marineindustry #marine #marinetechnology #marineengineer #merchantnavy #seafarers #sea #air #pollution #pollution #marpol #solas #marineengineer #lifeatsea Amet University Chennai , International Maritime Institute , Columbia Aurus Ship Management Pvt.

Carbon emission footprint in Welding industry > Compiled and Written by Alireza Alvandi. The Welding industry, like many others, has a significant impact on the #environment , particularly in terms of carbon emissions. As a #society , we are becoming increasingly aware of the need to reduce the amount of #CarbonDioxide that we emit into the #atmosphere . Carbon dioxide is a #GreenHouseGas that is responsible for trapping heat in the Earth's atmosphere, which leads to global warming. The emission of carbon dioxide from human activities is one of the main contributors to this, and the #WeldingIndustry is no exception. The welding process releases carbon dioxide into the atmosphere due to the use of fossil fuels, such as #coal , #oil , and #NaturalGas , as energy sources. The heat required for welding also releases carbon dioxide from the burning of fossil fuels. Additionally, the production of welders and other welding equipment also contributes to carbon emissions. To reduce the environmental impact of the welding industry, several steps can be taken. One of the most effective methods is to switch from fossil fuels to hydrogen and clean energy sources, such as #solar , #wind , and #hydropower . This can significantly reduce the amount of carbon emissions produced by the welding process. Another effective way to reduce carbon emissions is to improve welding processes and equipment. One way to do this is to invest in higher-efficiency welders, which use less energy and produce less carbon dioxide. Another effective strategy is to use #ElectricalPower instead of fossil fuels for welding, which can significantly reduce the amount of carbon emissions released from the welding process. It's also important to promote the use of renewable materials in welding, such as recycled #steel and #aluminum . This can help reduce the dependency on #fossilfuels for welding and encourage the use of sustainable materials. Prevalent, it's essential for the welding industry to adopt sustainable and environmentally friendly practices to reduce the amount of carbon emissions released into the atmosphere. By doing so, the industry can help tackle the challenges of #ClimateChange while continuing to create safe and durable structures. #welding #carbonfootprint #carbon #carbonemission #engeenering

#GoodDayatSea #emissions #FuelEUMaritime #dandcrewing #crewing #crew #maritime #seafarers #shipping #maritimetransport First publicly available FuelEU Maritime calculator is here The first publicly available FuelEU Maritime calculator has been released by zero44, a Germany-based provider of digital CO2 management solutions, to help prepare shipowners for costs associated with the upcoming FuelEU Maritime regulation. As explained, the aim behind developing this tool is to enable shipping companies to quickly and easily understand the financial impact that the planned FuelEU Maritime regulation will have on their business. The results are estimates and not binding, but provide a good initial basis for dealing with the costs and cost factors of FuelEU Maritime, according to the company. While the majority of shipping companies are still working on becoming EU ETS compliant, the next comprehensive legislation to decarbonize shipping is already on the horizon: FuelEU Maritime. Aimed at kick-starting the large-scale production of sustainable marine fuels, FuelEU Maritime’s main focus is decreasing vessels’ yearly average greenhouse gas (GHG) intensity. This is the amount of greenhouse gasses that are being emitted for every MJ of energy that is used onboard a vessel. The regulation will enter into force in January 2025, dictating a GHG intensity limit that is two percent lower than the 2020 reference. This means that many vessels, when continuing business as usual, will face hefty non-compliance penalties immediately from the start of the regulation. GHG intensity targets will get stricter every five years, all the way to an 80 percent decrease in GHG intensity from 2050 on. In addition, a mandate for the use of onshore power supply and a sub-target for a two percent share of e-fuels in a vessel’s fuel mix will apply from 2030 and 2034 respectively. The scope of FuelEU is similar to that of EU ETS, covering 50 percent of the energy used on voyages arriving at or departing from EU ports, and 100 percent of the energy used on voyages between EU ports for vessels larger than 5,000 gross tonnes. One of the main differences is that FuelEU covers the emissions over a fuel’s entire lifecycle (from well to wake), instead of only tank-to-wake emissions. Simple calculation of FuelEU Maritime costs There is already a lot of information available on FuelEU Maritime but it is mostly technical, regulatory or scientific. In contrast, it has been difficult for companies to get a concrete idea of how FuelEU Maritime will affect their business.

Ammonia as green fuel? Is it what the maritime industry needs for sustainability? Considered as the "Teslas of the sea," ammonia-fueled marine vessels are becoming the hottest topic in the maritime industry. In the search for feasible fossil-free fuels for marine vessels, ammonia has been on the agenda for quite some time as one of the strongest alternatives. Aiming to meet the International Maritime Organization's (IMO) targets regarding carbon emissions, more newbuildings are leaning towards cleaner fuels to align with these set targets. However, despite having clear advantages in some areas, such as lower emissions due to emitting mainly nitrogen and water vapor, renewable production opportunities, higher energy density (higher than hydrogen), and already existing infrastructures for production, there are some drawbacks related to this transition. Most of these drawbacks that are being discussed revolve around the costs of transition, technological advancements required for the infrastructure to meet the increasing demand, and some other issues regarding feasibility in technical terms. The problem is, in order to produce ammonia, huge amounts of electricity are needed, making it really energy-intensive. So it will all boil down to the method of electricity production to assess the cleanliness of ammonia as a marine fuel and is likely to be overlooked. Another problem, despite ammonia being carbon-free, is that its combustion engines do release greenhouse gases, namely, laughing gas (a very potent greenhouse gas, 200 times more impactful than CO2, according to researcher Selma Brynolf). Therefore, even the strongest pro argument of the transition to ammonia-fueled engines has a shaky base to support. The biggest (by far) drawback is the health-related hazards concerning the handling of ammonia. Exposure to high concentrations of ammonia in the air is dangerous and could lead to burning in the eyes, nose, throat, and respiratory systems. Additionally, it could lead to blindness, lung damage, and death. So this adds another dimension with an ethical perspective into the equation. There was one accident related to ammonia leakage on a marine vessel, where one crew member died and three others were severely injured, on April 6, 2021, in Malaysia. Is ammonia the future of the green maritime industry? Really curious about your thoughts as maritime professionals.

🌊 Navigating Towards a Greener Future in Maritime Trade 🚢 Did you know that shipping contributes about 3% of the world's annual greenhouse gas (GHG) emissions? As the backbone of global trade, innovators like Hydro Hull Cleaning are stepping up to address this challenge. The International Maritime Organization (IMO) is spearheading efforts to reduce emissions through innovative ship design and operational improvements. One significant contributor to emissions is biofouling – the accumulation of microorganisms on a ship's hull, causing drag and increased fuel consumption. A recent IMO report highlights the profound impact of biofouling on energy efficiency and emissions. Even a thin layer of biofouling can raise emissions by 25-30%, while severe cases can spike emissions by up to 90%. This underscores the urgent need for solutions. Hydro Hull Cleaning's groundbreaking SeaBadger MkII is at the forefront of combating biofouling. With its innovative technology, we're setting new benchmarks for effective and eco-friendly hull cleaning. By addressing biofouling head-on, we contribute to the reduction of global GHG emissions by up to 19%, paving the way for a more sustainable maritime industry.

The shipping industry has a goal to reach net zero emissions by 2050, but there are questions as to whether this is achievable. A lot of things need to change or be improved, including new technologies in ship design, like smaller engines and improved hull shape — or perhaps lower-cost solutions like wind power, waste heat recovery, and more. Low- and zero-carbon fuels are also a consideration. While the shipping industry is committed to achieving this goal, the transition will be challenging. #thefreightarchitects #jaguarfreight #logistics

How to make the carbon emission monitored and fully accountable is the real challenge. A good approach is to start, then correct, to adjust and to finally achieve an equation that will harness the information time to time…to be again assessed. #GettingBetterByDoing #LinkPower

As #COP28 came to a close, the World Shipping Council (WSC), liner shipping’s lobby group, shared a new position paper with the International Maritime Organization that it said it believed were critical to an “effective” agreement on GHG reduction. The paper calls for the swift implementation of GHG fuel intensity standards, some form of a carbon levy, regulations based on well-to-wake life cycle analysis of all fuels, and vessel pooling options for GHG regulatory compliance. If implemented as the paper suggests, all of these measures would drive the uptake of future fuels and low carbon technologies, including carbon capture & storage. Wärtsilä has the most comprehensive portfolio of decarbonisation technologies, with engines, propulsion systems, hybrid technology, integrated powertrain systems and carbon capture & storage solutions. We therefore applaud this initiative from the leaders of the industry. Read more via Splash Maritime and Offshore News (splash247.com): https://lnkd.in/dTpSiFuh
