New Guidance Published on Marine Transport of Ores and Concentrates
Updated guidance from the International Council on Mining and Metals (ICMM) outlines the techniques required for accurate hazard assessment of ores and concentratesAiming to help minimize the risk of accidents in maritime transportation, the Hazard Assessment of Ores and Concentrates for Marine Transport: Guidance 2021 brings the previous guidance issued in 2014 in line with recent regulatory updates from the International Maritime Organization (IMO) and advancements in knowledge in assessing hazards.Through ICMM’s Mining Principles…
NRL Models Deepwater Horizon Oil Spill
Dr. Jason Jolliff is an oceanographer with the U.S. Naval Research Laboratory (NRL). "The emphasis here," he says, "is on developing models of the ocean environment to help the naval warfighter." His most recent paper, published in Ocean Modeling (March 2014), shows NRL can also forecast where oil will go following a major spill. "If you're going to do forecasting," he says, "you have to get the ocean circulation correct. It's fundamental to all else." Jolliff plugged the distribution…
Coast Guard Icebreaker Begins 2012 Arctic Missions
U.S. Coast Guard Cutter 'Healy' begins the first of three Arctic missions scheduled during 2012. Healy departed its homeport of Seattle July 30, for a deployment that will include three missions that support scientific research in the Arctic. After a brief stop in Dutch Harbor for logistics and to welcome aboard the 38 members of the HLY-12-01 science party, the cutter continued its northbound transit through the Bering Strait to the Chukchi Sea. The first science mission the Healy crew is scheduled to conduct is a part of the Chukchi Sea Offshore Monitoring in Drilling Area (COMIDA) project…
Low Sulphur Fuels Cause Pump Deterioration
Due to new regulations, the shipping community is faced with new challenges on a large scale, especially those ships that operate both inside and outside environmental zones and switching over from one fuel to another. For a long time the traditional approach to operation on heavy fuel oils (HFO) has been “pier-to-pier”. This is all going to change, said Allweiler, a world-leading provider of marine pumps to the shipping industry. When global ship operator BW Gas overhauled a low-performing fuel service pump, it discovered high wear on pump elements. BW Gas concludes that a contributing factor to the increased wear rate on the pump can be the 0.1% Sulphur marine gas oil used in EU ports, however it is also clear that other factors play a significant role.
