With a growing focus on mitigating climate change and progressing toward the International Maritime Organization’s (IMO) 2050 net-zero target, the marine sector is under intense pressure to decarbonize. Today, maritime transport emits nearly one billion tons of CO2 annually, representing roughly 2-3% of all energy-related carbon emissions worldwide .Substantial progress has been made over the past decade in reducing emissions from small commercial and coastal vessels via all-electric and diesel-electric propulsion (DEP) systems.

In April this year, the IMO Marine Environment Protection Committee approved guidance on in-water cleaning of ships' biofouling and also approved a proposal for the development of a legally binding framework for the management of biofouling.The move comes in recognition that biofouling is a key contributor invasive species and to greenhouse gas emissions. Biofouling can increase fuel consumption by up to 30%, costing the shipping industry $40-50 billion annually and driving excess…

U.S. Transportation Secretary Sean P. Duffy has announced that the Maritime Administration (MARAD) has awarded $8.75 million in grants to revitalize U.S. shipyards and advance America’s maritime dominance.The funding is part of the Small Shipyard Grant program, which supports advanced training, workforce development and new technologies that strengthen U.S. shipbuilding and repair capabilities. Duffy said the program will help America counter Chinese competition and maintain freedom…

The Coast Guard (including its heritage services) have employed boats since the beginning. Boats are just as important, if not more so, than ever.America’s first “boat force” came about in 1878, with the creation of the United States Life Saving Service (USLSS), whose boat crews rescued mariners in distress along the nation’s coast line. In 1915, the USLSS merged with the United States Revenue Cutter Service (established in 1790) to form the modern-day United States Coast Guard.

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…
