Underwater welding is one of the most demanding and hazardous tasks in the maritime and offshore world, relying heavily on a small, highly specialized pool of industrial divers. As port infrastructure ages and offshore structures expand, demand for underwater repair continues to outpace available manpower. A new research project out of Germany aims to fundamentally change that equation.Led by the German Research Center for Artificial Intelligence, the MARIOW (Maritime AI-Guided…

Next Generation Shipyards (NGS) in Lauwersoog has taken a major step toward modernizing its production line with the installation of a new state-of-the-art robotic welding system, technology that the yard says will boost efficiency, improve weld quality, and strengthen its competitive position in the specialized workboat market.The nature of shipbuilding has historically limited the usefulness of welding robots, which are typically designed for repetitive, standardized production environments.

The U.S. Navy needs to dramatically increase the fleet, especially submarines, but the available pool of skilled workers is not keeping pace.Submarine construction is ramping up. The Navy continues to build Virginia-class submarines, striving for two per year, and is gearing up build the new Columbia-class of nuclear-powered ballistic missile submarines. At the same time, the industry needs to support the ambitious Australia-U.S.-U.K. AUKUS program to make the Royal Australian Navy a nuclear submarine navy.Qualified workers are not only needed to build submarines…

To increase the efficiency of welding equipment calibration, verification and validation, ESAB has introduced the Checkmaster 600R resistive load bank for simulating GMAW, AC/DC GTAW, SMAW and SAW arc welding processes from 150 to 600 amps.

After developing the technique some five years ago, Aker Arctic has now completed the research required to get its new design methodology for icebreaker hulls accepted into the Finish-Swedish Ice Class Rules. The method has also been adopted to Polar Class rules of several Class Societies (LR, ABS, DNV).Although the research focused on vessels typically sailing the Baltic Sea, Aker Arctic has also used the methodology in many of its recent newbuilding designs including, for example, Canada’s new icebreaker which is currently under construction.

Colonna’s Shipyard is a fifth-generation, family-owned medium-sized shipbuilder, led by Randall Crutchfield, Chairman & CEO, today. Founded in 1875 by 26-year-old ship carpenter Charles J. Colonna with a $2,000 loan from his brother, he founded a company that has not only withstood the test of time, but today stands ready as a multi-faceted ‘blue collar industrial complex’ to help in the effort to effectively rebuild the U.S. shipbuilding base, and more specifically to help rebuild the U.S. Navy and U.S. government-owned fleet of ships.

Uncle Sam wants you — to choose a career in welding. The chronic shortage of qualified welders has been well documented. The American Welding Society (AWS) even created a website — www.weldingworkforcedata.com — so that industry and the media could share accurate data. Currently, the U.S. needs 330,000 new welding professionals by 2028.While some may shrug at the shortage of welders in the offshore, marine and civil fabrication industries, the need for welders to shore up the U.S.

The efficacy of surface preparation and coating application in the new construction shipbuilding industry is fundamentally anchored in a well-coordinated, integrated approach. This intricate process, essential for achieving top-tier corrosion control, is methodically segmented into five crucial stages:Raw material entryPainting the modulesSmall partsPainting of erection joints at the module levelFinal paint and ship's completion. Each stage is crucial in its own right but achieves…
