Ammonia Advances
Taking a well-to-wake approach to CO2 emissions means that the shipping industry will look beyond emerging engine technologies such as dual-fuel ammonia engines when considering the viability of alternative fuels.Engine manufacturers are optimizing combustion and reducing pilot fuel requirements, but any pilot diesel requirements mean the process is not 100% carbon free.This week, Hanwha Power Systems, Hanwha Ocean and Baker Hughes announced a different concept. The companies agreed to design and produce low carbon ammonia gas turbines capable of 100% ammonia combustion.

New Cylinder Pressure Sensors for Controlling and Monitoring Large Engines
In view of the investment costs, large engines should be particularly well protected and future-proof. STW's new SMX.pt-ea1 cylinder pressure sensors help to improve fuel efficiency and reduce greenhouse gas emissions by optimizing combustion. At the same time, they monitor key engine parameters and prevent engine damage.In all areas of application for large engines - marine propulsion, power generation, rail transportation and gas compression - reducing greenhouse gas emissions is among the most important development goals.

Survitec Urges Fire Safety Reform for Methanol-fueled Vessels
Survitec, a provider of survival technology solutions, has welcomed recent fire safety guidance from classification society DNV but warns that additional steps are necessary to ensure methanol-fuelled vessels are fully fire-safe.In a study published in their White Paper, “Do we need new fire safety standards for methanol?”, Survitec reveals that traditional fire-fighting methods are inadequate for dealing with methanol fires. The findings, presented this week at the SMM trade fair in Hamburg…
Canadian-led Research Project Reveals Ways to Reduce Underwater Noise from Ships
As the international shipping industry continues to explore measures to conserve and protect underwater life, the International Maritime Organization (IMO) is proposing the future monitoring of Underwater Radiated Noise (URN), which may lead to the establishment of thresholds combined with long-term monitoring requirements for certain regions.Underwater noise from ships can significantly impact marine life by disrupting communication, navigation, and feeding behaviors in various species.

Liebherr Tech Helps Drive Wind-assisted AYRO
Liebherr worked with AYRO, the French industrial start-up that recently successfully equipped the Canopée vessel with four OceanWings, making it the first hybrid industrial cargo ship powered by wind.With a height of 37 metres and a surface area of 363 m² each, this automated, lowerable and patented vertical wingsail technology will help the ship cut fossil fuel consumption.AYRO’s 37-m-high wingsails require a special solution due to their size, especially regarding its electrical actuators.
Superyacht Liva° Breaks Records
Spanning more than 118 meters long, Liva°, delivered in August, is the largest superyacht to date built by the Abeking & Rasmussen shipbuilder in Lemwerder, Germany, near Bremen. However, its length is by no means the only record-breaking feature that the shipyard offers in the superyacht segment. The sleek black hull is a visual highlight that draws the observer’s gaze to focus entirely on the elegant silhouette. All technical necessities are accommodated in a way that makes…
