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…

The international shipping industry as a whole is responsible for 2% to 3% of global greenhouse gas emissions, and if nothing changes, those will increase by 250% by 2050, according to the International Maritime Organization (IMO). Sobering numbers like these have made reducing emissions across the sector a focus for governments, shipbuilders, environmentalists, vessel owners and technology suppliers alike.The United States federal ship fleet, excluding combat ships, consists of various types of vessels utilized for civilian purposes. This fleet of vessels makes the U.S.

Two decades into the 21st century, we’re seeing a growing and pernicious threat to global information security: ransomware. Even non-technical folk have loosely heard of it, but the broader implications haven’t yet penetrated the public consciousness. In different industries, that general lack of awareness could be a big problem—and the maritime sector is a good example.Ransomware hits at the confluence of two critical trends in modern technology: the ever-increasing integration of IT systems into daily life, and the interconnectedness of those IT systems.

With thousands of miles under her keel ferrying passengers from Woods Hole, Mass., to the private island of Naushon, part of the Elizabethan Island chain south of Woods Hole, the Comorant just underwent a four-month refit at Gladding-Hearn Shipbuilding, which built the vessel in 1979. Pret Gladding, a co-founder of the Somerset, Mass.-based shipyard, designed the 56 ft., 49 passenger ferry for the Naushon Island Trust. The Cormorant is the year-round lifeline to this small island community…

Unappreciated, but heavily used by operators and closely regulated by the authorities, lubricants can also be a welcome part of your environmental and sustainability program. That’s right: lubricants.When it comes to the ideal operating scenario on any marine platform, the challenge of balancing sustainability with maximum operational performance and arriving at a healthy bottom line has never been more difficult. That said; the arguably perfect solution involves using on board consumable product(s) that contribute to sustainability, operational, and energy efficiency goals.

As Oceanology International celebrates its 50th Anniversary, Marine Technology Reporter explores half a century of subsea technology development and discovery. Oceanology International Americas runs February 25-27, 2019 in San Diego.When Oceanology launched in 1969 in the seaside resort of Brighton the world was a very different place. For a start, Brighton was home to the mods and rockers, who would square off against each other on the town’s elegant seafront. The British currency included shillings and ha’ pennies and man had yet to step foot on the moon.More crucially…

Seabourn Cruise Line's newest ultra-luxury vessel, Seabourn Ovation, achieved another important maritime milestone with the completion of its final round of sea trials in the Mediterranean off the coast of Italy. Seabourn Ovation departed the Fincantieri shipyard on March 14 for four days at sea, where a team of officers and engineers tested the ship's technical and mechanical systems. Seabourn Ovation returned to the shipyard in Genoa on March 18, and staff and workers are putting the final touches on the ship. The delivery ceremony of the ship is on schedule to take place on April 27, 2018. "We're now weeks away from delivery, and I'm very pleased with the progress and preparedness of the ship now that sea trials are complete," said Richard Meadows, president of Seabourn.

The remarkable success of autonomous and remotely-controlled vehicles on land and in the air and the interest in this technology being shown within maritime circles suggests that it is only a matter of time before autonomous ships are deployed at sea. Although the fuel costs represent, by far, the majority of shipping costs compared to onboard crews, there are yet substantial benefits to be reaped from autonomous ships. The potential economic benefits are too great to ignore this emerging technology.

The marine industry as a whole is responsible for about 2.5 percent of global greenhouse gas emissions. Shipbuilders and fleet owners have spent the last two decades adjusting to shifting emissions regulations since the introduction of the MARPOL Convention 1997 Protocol, which included specific regulations for the reduction of air pollution from marine vessels. Since then, there have been additions and amendments to ensure that the industry is doing its bit to better support the environment, with the latest regulation pulling forward lower caps in global emissions.
