In the turquoise waters of Honolulu, C-Power recently completed an in-water harbor test of the SeaRAY autonomous offshore power system (AOPS) that will soon be deployed for a six-month pilot project at the U.S. Navy’s Wave Energy Test Site (WETS) off the Hawaii coast.

Converted energy from waves powering a Saab Seaeye Sabertooth autonomous vehicle operating in seabed residency mode is a major renewable energy breakthrough.

C-Power today announced the addition of a groundbreaking demonstration of a Saab double-hull Sabertooth hybrid autonomous underwater vehicle (AUV) to the six-month sea trial of the SeaRAY autonomous offshore power system (AOPS).

BIG ISLAND, HAWAII July 1, 2019 – Jupiter Research Foundation and Whale Trust are pleased to announce the publication of the results of the first leg of their autonomous Wave Glider HUMPACS (Humpback Pacific Survey) acoustic survey in Journal of the Acoustic Society of America – Express Letters. During a 100-day nearly 7,000 km (3,800 nm) round trip survey on a line between Hawaii and Mexico within the 2018 winter breeding season, humpback whale calls were heard in mid-ocean basin, halfway between the known near-shore assemblies.

The Sea Based X-Band Radar (SBX-1) a floating, self-propelled missile tracking system operated by the U.S. Missile Defense Agency consists of an X-band radar array mounted on a 50,000 ton twin-hull semi-submersible. SBX-1 uses four azimuthing thrusters for propulsion and positioning and the requirement to change-out the forward-starboard thruster waterborne fell to Phoenix International. Working closely with thruster OEM Wärtsilä Defense, the Phoenix team of divers and technicians installed a unique underwater hydraulic trolley system to allow the 25-ton thruster to be moved outboard of the thruster well once separation from the steering pipe was complete. This innovation was required because the semi-sub deck overhang coupled with a shallow Pearl Harbor repair berth precluded a direct yard-and-stay procedure. The Phoenix team was able to remove the existing thruster and, reversing this process, install a rebuilt thruster all within the tight timeline stipulated by the ultimate client. As the thruster work commenced, our client asked if Phoenix could also prepare SBX-1 for and perform an ABS in-water survey (IWS) in parallel with the thruster change-out. Our Pearl City location and Hawaii based team allowed us to answer in the affirmative and we went to work immediately performing waterborne hull cleaning, shell-plate thickness gauging, sea-chest blanking, and visual inspection with an ABS surveyor in attendance. During the inspection our divers discovered fishing net inside the aft-port thruster. They subsequently removed the rope guard, cut away all netting, inspected the thruster seals and re-installed the rope guard. All pre-inspection, inspection and repair work was conducted while the thruster change-out was in-process.

University of Hawaii researchers partner with Schmidt Ocean Institute to map 11,000 square kilometers of the ocean floor, creating detailed images of major seamounts. HONOLULU, HAWAII – In a recent research expedition sponsored by Schmidt Ocean Institute (SOI) and led by University of Hawaii scientist Dr. John R. Smith, over 11,000 square kilometers of the ocean floor were mapped in high-resolution for the first time. Smith, working with Jonathan Tree, University of Hawaii, and Joyce Miller, used multibeam sonar on SOI’s research vessel Falkor to generate detailed maps of portions of the remote Johnston Atoll Unit (JAU) of the Pacific Remote Islands Marine National Monument (PRIMNM).
