Crews on Monday, January 6 2020, placed the 150-ton section of the capsized vessel M/V Golden Ray inside Reef SFC approximately 20 miles east-southeast of St. Simons Island, after all materials were inspected for cleanliness, to be used as an artificial reef for maritime species.

Read moreDetailsKongsberg Maritime has successfully adapted a propeller concept used in naval applications, aiming to provide operational and environmental benefits to commercial shipping customers. By deploying such a technology can significantly reduce cavitation-induced noise and erosion risk.
Read moreDetailsIMCA published a safety flash according to which a vessel had both of its main propellers caught in fishing nets. The incident took place a nautical mile off shore, after a three-day waiting on weather. If hazards are observed and considered by the Officer of the Watch (OoW) to pose a significant risk to the vessel, consider suspending operations.

Read moreDetailsA miscommunication between a crane operator a platform supply vessel's crewmembers, led a mooring rope to the side of the vessel. After that the port side engine shut down and there was partial loss of vessel propulsion. The deck crew did not notify the bridge in time when the rope was lowered into the water, and thus the propeller was fouled by the rope.

Read moreDetailsThe video, produced by Science Channel, shows a 23-foot propeller which gets cast in one piece, an alloy of eight metals – mostly copper- at 1,800 degrees Fahrenheit. It takes five days for it to cool into one big lump and then workers have to extract the propeller from its mold without damaging it.
Read moreDetailsAn increasing trend in reported incidents involving aft propeller shaft bearing damages has been observed. DNV GL cites what is suspected to be one of the contributory factors to some of these types of damages, namely operation involving incomplete propeller immersion.
Read moreDetailsA joint research project carried out by Wärtsilä and City University London has succeeded in identifying the specific design parameters that create the risk of ‘singing’ propellers. Though rare, ‘singing’ is nevertheless an annoying problem that occurs as a strong tonal noise originating from the propeller, thus causing a negative effect to onboard comfort levels.
