Fuel-agnostic and suitable for newbuilds and retrofit, Organic Rankine Cycle waste heat recovery systems are making headway as an energy-efficiency measure.Market prospects are looking so good for waste heat recovery systems that Orcan Energy recently expanded its industry relationships by partnering with Goltens on installations.Andreas Sichert, CEO of Orcan Energy, said: “Waste heat recovery is one of the most powerful and underutilized tools for improving energy efficiency.

It’s no surprise that waterjets are great for shallow-draft, highly maneuverable craft, but vessel designers are busting out of the old stereotypes.Vessel designer Aircat Vessels has developed a surface effect ship (SES) crew transport catamaran, AIRCAT 35 Crewliner, that can sail at over 50 knots and manage offshore transfers in 2.5-meter seas. The air cushion system from ESNA dynamically adjusts to sea conditions so the vessel can reduce transit times, reduce fuel consumption…

Australia does not have nuclear power stations, and it does not have nuclear weapons.I remember having lessons and debates on it in high school, many years ago. My favorite science teacher was dead against either use of nuclear technology.One of the most interesting arguments I remember hearing was that the technology developments that make nuclear power more efficient would also help make nuclear bombs more efficient.Fiji is much the same as Australia, and it has even ratified the Treaty on the Prohibition of Nuclear Weapons…

Preparing for industrialization, the floating offshore wind industry is tackling its unique mooring and cabling challenges.The idea of keeping floating offshore wind platforms in place using dynamic positioning has been considered. The trouble is: it could take up to 80% of the electricity generated by the turbine to do it.So, as Maersk Supply Service said a few years back: In a field of 100 turbines with 4-5 mooring lines each, there is going to be a lot of subsea “spaghetti.” It’s not a problem unique to the industry…

Global solar deployment to add 3.8 TWac of new project capacity by 2033 compared to 1.6 TW of wind power, while 640% growth is forecast for energy storageFrom 2024 to 2033, developers will bring more than 5.4 terawatts (TWac) of new solar and wind capacity online, increasing the cumulative global total to 8 TWac, as the world endeavours to electrify economies and meet decarbonisation targets, according to latest analysis by Wood Mackenzie.Energy storage capacity (excluding pumped hydro) will grow by more than 600%, with nearly 1 TW of new capacity expected to come online in the same period.

When Bertrand Charrier worked with Jacques Cousteau four decades ago on the development of a revolutionary sail for the maritime industry, the time for widescale adoption of wind power wasn’t right. Now, he argues, there’s simply no time to waste.“Sometimes the best discoveries are rediscoveries.”Bertrand Charrier is a champion of simplicity. Sitting in a comfortable chair overlooking the rolling fields of rural France, he delivers frank observations backed by a blend of common sense and scientific expertise.The maritime industry…

30 years ago shaft generators with PTI capability kept container ships sailing at top speed. That purpose gone, PTI/PTO is making a new comeback in more cargo shipping segments, this time for reducing emissions.Retrofitting a shaft generator is not an insignificant undertaking. Around 50 tons of equipment needs to be installed into the engineroom through a hole in the hull. A new section of shaft is usually required.That a few shipowners are undertaking such projects - Klaveness Combination Carriers on the Ballard…

Fuel flexibility may be a key driver for recent developments in gensets, but the perennial goals of lowering CapEx and OpEx remain.Fuel flexibility is one of the pillars of decarbonization that is being embraced by genset OEMs. Fuel efficiency, a second pillar, goes hand in hand with that because new fuels will be more expensive, but these concerns come in addition to the on-going drive to reduce CapEx and OpEx for shipowners.MAN Energy Solutions introduced its auxiliary MAN 35/44DF CD engine in June 2023. It is designed to be future-proof and will be ready for methanol operation by 2026.

BP and EnBW are collaborating with research and development experts at the UK-based Offshore Renewable Energy (ORE) Catapult to investigate using zero- or low-emission support vessels at offshore wind farms.The two companies are jointly developing three offshore wind projects in two UK locations – ‘Morven’, a potential 2.9GW lease area off the east coast of Scotland, and ‘Morgan’ and ‘Mona’ within a 3GW area in the Irish Sea. The offshore wind farms will require maintenance support from Service Operation Vessels (SOVs) and Crew Transfer Vessels (CTVs).According to ORE Catapult…

Developments in marine power today are centered on ever tightening legislative mandate which increasingly aim to dramatically reduce and eventually eliminate greenhouse gas emissions to the environment. While the holy grail of being truly ‘emissions free’ is still not feasible, there is much concurrent work in industry and academia to develop and source the fuels, the machinery technology, the logistical infrastructure and the business case for solutions that will meet the 2050 50% emission reduction mandates from the International Maritime Organization (IMO).

Greenhouse Gas (GHG) reductions of up to 21% are achievable now from LNG as a marine fuel, compared with current oil-based marine fuels over the entire life-cycle from Well-to-Wake (WtW).An independent study report confirms that emissions of other local pollutants, such as sulphur oxides (SOx), nitrogen oxides (NOx) and particulate matter (PM), are close to zero when using LNG compared with current conventional oil-based marine fuels.The study, commissioned by SEA\LNG and SGMF, was conducted by leading data and consultancy provider thinkstep according to ISO standards. The report, which has been reviewed by a panel of independent academic experts…

Offshore wind industry is set to gain a foothold in new markets in the next five years, with the Asian markets playing a significant role.China has significant ambition for the build-out of offshore wind – and added more capacity in 2018 than any other country. However, what is less known, is that markets such as Korea, Japan, Vietnam and India – have made plans to incorporate offshore wind into their energy mix.While much of the capacity being installed today is coming from mature markets such as Europe – where 18.5 GW was installed by the end of 2018 – most of the future growth will come from emerging markets.Asia Wind Energy Association…

Emerging spill response trends fit into two big categories: technology and a combination of economic and social forces. Both will shape what comes next.Florida’s stunning Tampa Bay stands out as exactly the kind of place where you have to think about hazardous materials emergencies. It was 25 years ago, on August 10, 1993, that a freighter collided with two barges near the entrance of Tampa Bay, causing a fire and spilling over 32,000 gallons of jet fuel, diesel, and gasoline and about 330,000 gallons of heavy fuel, devastating beaches, wildlife and habitat.

Devon Grennan, president and CEO of Global Diving & Salvage, and president of the Spill Control Association of America (SCAA) asks the tough questions. What are the biggest challenges the spill response industry faces in light of the current political and economic climate in the United States? And what is SCAA doing to meet these challenges? I see the primary challenge that the spill response industry – as well as SCAA’s membership – currently has is to manage expectations and competing interests at a unique point in our nation’s energy renaissance.
