Hydrex Earns Belgium, Netherlands Approvals

Belgium and the Netherlands, have banned the underwater cleaning on propeller blades. Exceptions are only made for those companies that can pass the very stringent tests carried out by the concerning authorities.Approved Approved propeller blade cleaning is carried out by Hydrex divers using underwater equipment developed in-house by the Hydrex R&D department. This process is fast and easy and has no effect on the underwater environment

The CTD cranes can operate and sample water to depths of 3000 m as well as handle underwater equipment ranging from small plankton nets and bottom corers and towing of multinets.The trawl gear is arranged for flexible and efficient operation with multiple net drums and flush deck hatches to two receiving bins. Laboratories are arranged adjacent to CTD Hangar, and below trawldeck to allow efficient

a containment system, and install it at the source to start collecting the oil. At present, the team is in the planning phase. Weather and sea state will largely dictate operations, which will involve cumulative weeks at sea, extensive dive and remotely operated vehicle (ROV) operations, and underwater equipment installation.  “While the safety of response personnel is paramount, we don’t want to delay response activities,” said U.S. Coast Guard Capt. Kristi Luttrell, the Federal On-Scene Coordinator (FOSC) for the MC20 response. “We plan to leverage every weather window

Allen was deeply invested locally in his hometown of Seattle and the Pacific Northwest, but his endeavors regarding the ocean spanned the globe.In 2016, Allen purchased the R/V Petrel, a 250-ft. research and exploration vessel and equipped it with a suite of advanced underwater equipment and technology to make it one of the few ships on the planet capable of exploring to 6,000 meters. Following a 2017 retrofit, Petrel and its crew use state-of-the-art underwater technology for deep-sea expeditions, and the team has made a number historic subsea discoveries, most notably the

JW Fishers Showcases Tech for Firefighters

Present day fire departments not only fight fires, but also answer medical calls, conduct rescue missions, assisting in evidence recovery, and execute underwater search operations. Underwater equipment manufacturer JW Fishers Manufacturing provides tools for fire departments across the globe.In April of 2018, JW Fishers attended the annual Fire Department Instructors Conference (FDIC) in Indianapolis, Indiana. The first conference was held in 1929 in Chicago and was organized to discuss training measures, standards and firefighting best practices. By 1939, attendance had reached a high of 247 people

US Navy to Survey Downed Aircraft in the Philippine Sea

(SUPSALV) personnel aboard the 250-foot RV Petrel will depart from the Philippines to survey and map the ocean floor of the wreck site using a side-scan-sonar and remote operated vehicle (ROV). The Allen-owned research and exploration vessel is equipped with some of the world’s most advanced underwater equipment and technology, making it capable of exploring depths to 6,000 meters.   After the survey, SUPSALV will analyze the data and assign a vessel, equipment and personnel as the Navy makes every effort to recover the aircraft and fallen sailors for recovery efforts.

Assodivers Orders Winch from MacArtney

Requiring a trenching umbilical winch for deployment of underwater equipment, Assodivers has placed an order with MacArtney for more winches.   The scope of supply of the order for Assodivers includes a trenching umbilical winch and an electric-optical slip ring. The winch is characterized by a self-contained, all steel welded construction with protection frame, drum, level wind, gear box, electric motor and switch board.

Scott Swift, commander of the U.S. Pacific Fleet.   The high-tech vessel used to find USS Ward, R/V Petrel, is a 250-foot research and exploration vessel purchased by Mr. Allen in 2016. Petrel's advanced underwater equipment and technology makes it one of the few ships on the planet capable of exploring to 6,000 meters deep (more than 3.5 miles). Following a 2017 retrofit, Petrel and its crew use state-of-the-art underwater technology for deep-sea search and exploration expeditions.    "The Petrel
