In August, Norway’s IKM Subsea reached a 100-day continuous subsea operations milestone with its tethered Merlin UCV R-ROV at the Snorre B facility offshore Norway, where it’s been based since 2018, along with a tool stand, supported by on and offshore staff.Oceaneering has been supplying

the sonar data in real-time, while submerged, and make decisions around that target recognition without needed a human's input or oversight,” says Kauffman. Testing of a 9m-long, 1 m-deep prototype (the commercial system will be smaller) is due to start in Lake Travis and then the US Gulf of Mexico closer in October. Tank testing of the energy recharge system was due to start in August.The ultimate goal is something like a Google Earth type software system users can sign into and then go to the bottom of the earth and fly through a 3D point cloud terrain we’ve built, says Kauffman.

Callan Marine Wins North Breton Island Restoration Project

reached in 2016.Located northeast of Venice, La., the restoration project includes dredging 5.7 million cubic yards of material in order to restore the barrier shoreline through beach, dune, and marsh fill placement. It will utilize an offshore sand source located just a few miles away in the Gulf of Mexico.Callan Marine will deploy the General MacArthur, Callan's new 32” cutter suction dredge, to complete this work. At 290 feet in length and a nine-foot draft, the General MacArthur boasts 24,000 total installed horsepower. Powered by 3 Cat-MAK diesel engines, the dredge has a fuel capacity

C-Innovation Installs Stem Clamps on BP's Mad Dog Spar

Subsea ROV services provider C-Innovation has installed several stem clamps for BP under the Mad Dog Spar platform in the U.S. Gulf of Mexico.Informing of the completion of the project for BP, C-Innovation said it had used its subsea inspection, maintenance and repair (IMR) remotely operated vehicle (ROV) vessel, MV Dove, for the project.The subsea services company, an affiliate of Edison Chouest Offshore (ECO) said the project was completed 10 days ahead of BP’s schedule.The company modified the ROV, including armoring with Lexan polycarbonate, design of new manipulator mounting subframes to

Panther Wins GOM Pipeline Inspection Deal

ACSM chose an electric Saab Seaeye Panther XT robotic vehicle for pipeline inspection in the Gulf of Mexico. The Panther inspected 261 pipelines totalling 2,340 km in four fields in the Gulf of Mexico (GOM), at depths ranging from 15 to 130 metres, in a less than 10 month project duration.ACSM, a maritime, survey and ROV services operator, said that considerable savings come from deploying the 700 kg Panther system.Rated for 1000 m, Panther’s can accommodate a wide range of tooling with a ‘plug and go’ simplicity that makes it easy to change, maintain and repair systems.The ROV’s

Met (Meteorological) Office, the Icelandic volcano Eyjafjallajökull erupted in April 2010. She had a direct role in the ensuing crisis since the Met Office functions as the regional prediction center for global ash production. Later that month, the Deepwater Horizon oil spill occurred in the Gulf of Mexico, near where Virmani had previously lived and worked. She was asked to return to Florida to help with the spill’s aftermath and did so later that year. Several years later in 2017, while working as the senior director for the XPRIZE Foundation Plant and Environment team, an entire test bed off

could claim the cost of cutting fishing nets that were caught on a cable.Pipelines followed 100 years laterDespite the first onshore pipelines appearing in the 1850s, it wasn’t until 1954 when they were first commercially constructed offshore. This was a 10 miles long gas pipeline in the Gulf of Mexico that was laid at a depth of between 20 and 32 feet.  Although obviously more robust than cables, and with the benefit of 100 years of technology improvements, pipelines have not been impervious to the threat of sea vessels. Armored enclosures and burying pipes in high traffic areas haven&rsquo

in artificial reef development for nearly 50 years. Numerous reef building materials have been used over the years. However, the first highly successful artificial reef development occurred during the mid-1970’s when 12 obsolete Liberty Ships were sunk at five different sites in the Gulf of Mexico. During deployment to the Freeport Liberty Ship Reef site in 1976, the Vancouver sank during a storm and settled to the bottom of the Gulf at its present position. Eleven other Liberty Ships and two tankers are located at other reef sites along the Texas coast. Brochures for these reef sites are
