Tidal Turbines: Is Better Ballast the Answer?
; Gray cast iron tidal turbine ballast usually comes in three possible designs to easily adapt to the specific technology of the gravity base: as a welded cylindrical base reinforced by ballast; as a welded base with a central stake, manufactured without formwork and that can be integrated onshore or offshore; as a reinforced concrete base. The solution represents a new technology to fix the device to the seabed that doesn’t require in-depth geological analysis and frequent maintenance because of its simple but robust design. It doesn’t pierce the sea floor and once removed

Carousel Turns Over New Leaf for Ecosse Subsea Systems
carousel which can be deployed on a range of specialist subsea projects. Carousels are used in the storage and transportation of subsea cables, umbilicals and pipes and enable the safe deployment of equipment from a vessel to the seabed. The Carousel was originally built and used on an offshore renewables project in 2014 after ESS identified a supply chain issue surrounding the availability of carousels required for renewables and oil and gas workscopes. ESS managing director, Mark Gillespie, said, “We spotted a gap in the market regarding the supply of carousels and made

Rovco Secures Funding for 3D Visualization Project
Subsea technology company Rovco said it has secured Innovate UK funding to develop a cutting-edge 3D visualization system as part of a two-part Artificial Intelligence demonstrator project potentially worth £1 million. Working in partnership with the Offshore Renewable Energy (ORE) Catapult, the first phase of the project will see Rovco develop the equipment and software required to produce live 3D data from challenging and extreme subsea environments. The technology will be trialed and tested at ORE Catapult’s renewable energy test facility in Blyth. Phase two will
ASV’s C-Worker 7 Goes to Work for Subsea 7
A 7-meter autonomous surface vessel (ASV) was recently deployed to support offshore services provider Subsea 7 during pipelay operations off the coast of Egypt. The C-Worker 7 vehicle manufactured by U.K. firm ASV Global was fitted with a survey suite comprising a multibeam echosounder and side scan sonar in order to carry out touchdown monitoring in support of the pipelay vessel Seven Antares. A custom payload frame was designed to house the survey suite specified for the mission. The modular frame slotted into the C-Worker 7’s moonpool to mount and deploy the sensors. Extensive

US Senators from 12 States Seek Offshore Drilling Exemptions like Florida's
Twenty-two Democratic U.S. senators from 12 states on Thursday joined the chorus of local representatives seeking exemptions from Interior Secretary Ryan Zinke's newly proposed offshore drilling plan, after his surprise move on Tuesday to shield Florida. Zinke surprised lawmakers, governors, and industry groups on Tuesday night by announcing that Florida would be removed from the Interior Department's proposal to open up over 90 percent of federal waters to oil and gas leasing. Zinke had met in Tallahasee with Republican Governor Rick Scott who told the Interior chief that drilling
Scientists Study Largest Underwater Volcanic Eruption
In July 2012, airline passengers flying over the Southwest Pacific Ocean spotted a large and unusual object floating on the water’s surface. That object, which turned out to be a giant raft of pumice, was evidence that an underwater volcanic eruption had occurred. And as the raft continued to grow to roughly the size of Philadelphia, scientists observed that the eruption was extraordinarily large. The eruption had occurred at the Havre volcano northeast of New Zealand, and was the largest to take place underwater in the past century. “We knew it was a
Trump Offshore Oil Proposal Could Unlock 65 Bln BOE
The Trump administration's proposal to open up almost all of U.S. offshore waters to oil and gas drilling could unlock up to 65 billion barrels of oil equivalent (boe), attracting billions of dollars in investment, consultancy Rystad Energy said. Last week, U.S. Interior Secretary Ryan Zinke said a draft program would make over 90 percent of the outer continental shelf's total acreage available for leasing to drillers, a national record. "Looking purely at areas that are potentially going to come out of restriction, we are talking about something closer to 65 billion boe,"
After Florida, more States Press US for Offshore Drilling Exemptions
Governors and other officials from several U.S. coastal states ramped up pressure on the Trump administration on Wednesday to exempt their waters from an offshore drilling plan, hours after the Interior Department granted Florida's request to opt out. The backlash could complicate President Donald Trump's efforts to expand oil and gas production offshore. A proposed leasing plan unveiled last week aims to open up all U.S. coasts to drillers over the next five years. Alaska and Maine are the only two U.S. states whose governors have expressed support for the plan. The governors of

If Subsidized, Statoil Will Eye Norway's Offshore Wind
Norway's Statoil may take part in the country's first tender to build floating offshore wind turbines, as long as there are sufficient long-term subsidies, Chief Executive Eldar Saetre told Reuters on Tuesday. In December, Norway's Ministry of Petroleum and Energy said it planned to shortly open one or two offshore regions for construction of floating wind generation "If there are (offshore wind) opportunities in Norway being opened with a relevant incentive structure that makes it profitable, that's obviously something that we will assess," Saetre said on the sidelines of a conference.
