Propeller blade renewal intended to cut fuel consumption also has the potential to reduce underwater noise, reports Kari Reinikainen Efforts of the shipping industry to reduce fuel consumption and thereby pollution to the air may contribute to reduction of noise and vibration as well through the replacement of propeller blades. Rasmus Lyngdal-Christensen, senior specialist in […]
Luxury yacht owners have joined forces with maritime researchers to obtain an accurate overview of ocean colour, to help improve our understanding of the changing ocean. The initiative is being spearheaded by Dr Shubha Sathyendranath of Plymouth Marine Laboratory (PML) and Dr Robert Brewin of the University of Exeter, UK. Typically, scientists rely on satellites […]
Scientists at Aston University in Birmingham, UK believe they may have produced a viable alternative to traditional marine bunker fuels, care of a blend of leftover cooking oil, lamb fat and agricultural waste. The research project – undertaken in cooperation with colleges in Brighton (UK) and Madras and Chennai (India – saw the scientists take […]
The Maersk Mc-Kinney Møller Center for Zero Carbon Shipping (MMMCZCS) has published the methodology for its life cycle assessment (LCA) for calculating the GHG intensity of maritime fuels, in what it hopes will be a turning point in arriving at a standardised approach. Although by no means a problem that’s unique to shipping, it’s generally […]
RINA was delighted to be one of the sponsors for the Indian Maritime University’s (IMU) IMO Mock Session, the finals for which took place in early November. The aim of the competition, which is open to students and scholars of the campuses of IMU and its affiliated campuses, is to help students improve their soft […]
Most naval architects, boatbuilders, institutions and engineers will tell you about the pressing need to attract new blood into the maritime industry – but we rarely get to hear from the ‘new blood’ themselves. To address this, Ship & Boat International is considering handing over content to students for one special issue in 2024, so that they can […]
Both innovation and caution are key to overcoming the hazards of ammonia and enabling its use as a marine fuel, according to South Korean classification society KR As the maritime industry pivots toward more environmentally friendly solutions, ammonia has emerged as a promising alternative fuel under the International Maritime Organization’s (IMO) Global Greenhouse Gas (GHG) […]
It’s a familiar refrain, but the world’s oceans and its ecosystems remain largely unknown and unmapped by mankind. According to scientific estimates, 91% of ocean species have yet to be classified and at the current rate of progress it would take several millennia to achieve knowledge comparable with our current understanding of the Amazon rain […]
If Antarctica is a place of mystery, its surrounding Southern Ocean is not much better understood. What we do know is that these southernmost waters of the world ocean appear to be absorbing more carbon than they release – making the Southern Ocean the Earth’s main carbon sink. Yet, to date, these waters have neither […]
newcleo, a UK-headquartered nuclear technology company, has announced an agreement with shipbuilders Fincantieri and Italian classification society RINa to carry out a feasibility study into the application of small modular reactors (SMRs) in the shipping industry. In particular, the collaboration will explore the potential of using newcleo’s innovative LFR (Lead-cooled Fast Reactor) as a small nuclear […]
For the 10th instalment of its Annual International Student Design Competition for a Safe, Affordable Ferry, spanning 2022-2023, the Worldwide Ferry Safety Association (WFSA) shook things up by introducing a new stipulation for the participating teams. Although previous years’ contests had called for ferry designs to meet specific operational demands, the panel of judges had […]
Emil Jonze, Docksta Varvet, Sweden and Dr Ronald Pelot / John Dalziel MRINA, Dalhousie University, Canada explain why the Docksta Loitering, Optionally Crewed, High Speed Rescue Vessel concept was deemed necessary, and run though the features of this innovative life-saver The following article is a slightly truncated version of presentations delivered at the World Maritime […]
