Commercial shipping is a major source of greenhouse gas emissions (roughly 1 billion tonnes of CO₂ per year, about 3% of global emissions), reuters.com . To meet climate goals, the industry is exploring nuclear propulsion as a long-range, carbon-free power source. Unlike traditional ships that burn heavy fuel oil (releasing CO₂, SOₓ, NOₓ, and soot), a nuclear-powered vessel carries an onboard reactor that heats water into steam to drive its turbines. In effect, each nuclear ship is a floating power plant: its reactor core can operate for years without refueling, providing continuous electricity and thrust. This clean energy approach means virtually zero exhaust emissions at sea mdpi.com , which could dramatically cut shipping’s environmental footprint as we move toward the future of sustainable maritime transport. How Nuclear Propulsion Works Nuclear propulsion systems on ships work much like those on submarines and icebreakers. A compact atomic reactor aboard the ves...
Trailblazers of the Deep: Celebrating Women’s Legacy and Innovation in Naval Architecture & Marine Engineering
The maritime industry, once considered a man's world, has been impacted considerably by the will and ingenuity of women. From designing revolutionary ships to pioneering green marine technology, women have continually redefined naval architecture and marine engineering. Let us explore their remarkable contributions, challenges, and the evolving face of inclusivity. Historical Anchors: Pioneering Women Who Set Sail While women's official involvement in naval architecture gained momentum following World War II, their influence began sooner. Institutions like the Royal Institution of Naval Architects (RINA) today honor such names as Dr. Philippa "Pippa" Wilson, whose work in hydrodynamics during the 1960s revolutionized ship efficiency. Similarly, trailblazer Emily Roebling, no official engineer but a vital member in the 19th century, spearheaded the completion of the Brooklyn Bridge, a testament to early women's technological success, if often unsung. Eil...
