OSIL Rolls Out ROV/AUV Mounted Sediment Corer

U.K.-based Ocean Scientific International Ltd (OSIL) has introduced a new sediment corer designed to be mounted to the skids of remotely operated vehicles (ROV) or autonomous underwater vehicles (AUV).    The self-contained system will allow sediment samples to be collected during routine ROV operations and can be daisy chained together to allow multiple core assemblies to be installed as one system.  The assemblies are powered and controlled by the customers own skid control unit and have been pressure tested for use in depths of up to 1,200m, with deeper units currently in development

A U.S. Navy team has located a C-2A Greyhound aircraft that crashed in the Philippine Sea on November 22.   The downed aircraft rests at a depth of about 18,500 feet, making the salvage operation the deepest recovery attempt of an aircraft to date, the Navy said, adding it will make every effort will be made to recover the aircraft and fallen Sailors, despite very challenging conditions.   Eight of the 11 crew and passengers on board were recovered immediately following the crash. For the next three days, the U.S. Navy led combined search and rescue for the three missing Sailors with the

Corals at Risk as Underwater Heat Waves Strike More Often

High ocean temperatures are harming tropical corals almost five times more often than in the 1980s, undermining reefs' ability to survive marine heat waves caused by man-made climate change, scientists said on Thursday.   The average time between severe "bleachings", when heat makes the stony-bodied creatures that make up coral reefs expel colourful algae, shortened to six years in 2016 from 25-30 years in the early 1980s, the Australian-led team wrote.   Corals die if bleachings are long-lasting, wrecking reefs that are nurseries for fish, a source of food to millions of

Missing WW II Bombers Found on the Seafloor

follows successful identification and documentation of five missing World War II aircraft in 2016   Two B-25 bombers associated with American servicemen missing in action from World War II were recently documented in the waters off Papua New Guinea by Project Recover—a collaborative team of marine scientists, archaeologists and volunteers who have combined efforts to locate aircraft and associated MIAs from World War II.   The B-25 bomber is one of the most iconic airplanes of World War II, with nearly 10,000 of the famous warbirds conducting a variety of missions—from bombing

Sulzer: Total Supply Service for ROV Manufacturer

Manufacturing a hydraulic power unit (HPU) that is destined to operate on the ocean floor up to depths of 2,500 meters requires considerable expertise and design excellence in order to deliver reliable and sustained performance. Having provided the build and test service for some time, Sulzer has now taken on the procurement phase of the process to release the client from this time intensive task.   The design and construction of remotely operated underwater vehicles (ROVs) is a specialist field and the components used to create the HPUs need to be carefully selected in order to produce a

Partners Advance Arctic Oil Spill Response Technology

Continually working to help improve oil spill response technologies, the U.S. Bureau of Safety and Environmental Enforcement (BSEE) presented details on its latest efforts at the Arctic Oil Spill Response Research and Technology Workshop on April 26.   There, Bureau staff presented results of several BSEE-funded projects including the development of a submersible skimmer prototype for oil recovery in and around broken ice.   “At the workshop, we all worked together to collectively understand the suite of response technology possibilities that are available today as well as

Fishers Equipment Helps Locate Weapons and Explosives

 Before 1970 the widely accepted solution for disposal of old munitions, typically called unexploded ordnance (UXO), was to dump them into rivers, lakes and oceans. Today we know this creates a multitude of problems, the worst of which are pollution and the risk of an explosion. Many people have already lost their lives to these underwater booby traps. The uncertainties surrounding their precise location and degree of decomposition, makes attempting to recover these dangerous devices an even more difficult task.   Several international organizations have been formed to address the problem
