Kvaerner to Study Floating Wind Structures

cost and schedule improvement programs Kvaerner has implemented over the past four to five years.”Last summer, Equinor and its partners announced that they would explore the possibilities of using floating offshore wind turbines to supply power to the Gullfaks and Snorre fields. The oil and gas platforms could be the world’s first to receive parts of its power demand from floating wind turbines.The solution that is being considered is a wind farm consisting of 11 wind turbines based on Equinor’s Hywind floating offshore wind concept. The 8 MW turbines will have a combined capacity

thermal camera, FLIR Duo EO camera, Teledyne RESON T20 high resolution multi-beam sonar, Teledyne BlueView M900 single-beam echo-sounder and Norbit iWBMS STX multi-beam sonar, among others.This off-the-shelf technology can be used today to effect faster and more complete inspections of offshore oil and gas platforms along with their surrounding bottom mounted pipelines/valves and sensors, while dramatically decreasing the need for human divers. Under this concept, a 12-foot MANTAS USV would be controlled by one operator in the rig command center. This inspection of bottom valves, vertical pipes, fittings

said on Friday.Designed for sizes between 8” and 44” and temperature ranges from -4 to +80oC, the SIClamps provide new capability in the global pipeline market, which the Darlington based firm views as a great growth opportunity.The technology was developed for operational offshore oil and gas platforms who have had their working life extended and pipelines are required to last longer. With the increase in working life, EPRS support this by maximizing operational life and production efficiency and can be deployed at short notice.Dave Thompson, Managing Director at Subsea Innovation, said

Equinor Explores Floating Wind Turbines to Power N.Sea Oilfields

project at the Gullfaks and Snorre oilfields would cost around 5 billion Norwegian crowns ($592 million) and could reduce Norway's emissions of carbon dioxide by more than 200,000 tonnes per year, Equinor said."This could be the first time an offshore wind farm is directly connected to oil and gas platforms," state-controlled Equinor said in a statement. The two fields currently are powered by generators running on natural gas at the platforms.Norway's greenhouse gas emissions have remained high despite pledges for deep cuts under international accords such as the Paris climate deal

New Offshore Decommissioning Barge

Longitude Engineering reportedly has developed a cost effective decommissioning barge concept for the removal of small oil and gas platforms for the PTT Exploration and Production (PTTEP), a subsidiary of the Thai state owned oil company. The aim was to develop a viable and cost-effective alternative to conventional ‘reverse installation’ through the use of heavy lift crane barges for the removal of the topsides and jackets. The focus being the removal of 90-100 of PTTEP’s minimum facilities platform assets in the Gulf of Thailand, which have topside weights up to 800 tonnes and

Submarine Power Cables Protection

Submarine power cables are largely deployed in various offshore renewable energy sources such as wind, wave and tidal installations to transfer power to shore, but also in oil and gas platforms and ocean science observatories. They ensure the power supply to remote areas and by connecting regional electrical transmissions enable global energy trading.   The growing importance of the marine renewable energy sector and the word’s focus on environmental issues have made submarine power cables an infrastructure of critical importance. Most efficient and reliable installation and protection

cable to the field's Valhall platform which is in turn powered by a 294-kilometre long subsea cable linked to Norway's shore. "To our knowledge, this is the first one," said a company spokesman, citing data provided by the rig's owner, Denmark's Maersk, and other sources. Some oil and gas platforms off Norway already receive some power from land, such as Statoil's Troll A gas platform and Aker BP's Valhall. Statoil's giant Johan Sverdrup oilfield under development will also be powered from land. But this is the first drilling rig to get all its power from land, rather than from gas

agencies, and oil companies are left begging the question: should the rigs stay or should they go?   Emily Callahan and Amber Jackson, two alumnae of Scripps Institution of Oceanography at the University of California San Diego, have made it their mission to dive below the surface of these oil and gas platforms to determine the best possible “afterlife” scenario for these complex structures.   The two women met in 2013 while taking a scientific diving course at Scripps Oceanography, where both were pursuing Master of Advanced Studies degrees in Marine Biodiversity and Conservation

BOEM, BSEE Find No Significant Impact from OCS Well Stimulation

(BSEE) today published a joint environmental assessment on the use of well stimulation treatments in federal waters off California.   BOEM and BSEE completed a comprehensive environmental analysis evaluating the potential impacts from the use of well stimulation treatments on the 23 oil and gas platforms currently in operation on the Pacific Outer Continental Shelf (OCS), and based on the analysis in the Programmatic Environmental Assessment (EA), issued a Finding of No Significant Impact (FONSI) from the use of specific well stimulation treatments in oil and gas activities in the region

Today, most communications from oil and gas platforms and vessels to shore depend on expensive satellite links. The nCentric technology delivers a cost effective, efficient and reliable wireless network in large, hard-to-reach geographical areas.”   The nCentric technology can be used to monitor offshore operations, increase communicatio

It is a specialty radar systems developer creating software that can be used in conjunction with any manufacture of radar out in the field. Recent innovations include the Sigma S6 Sea Fusion system, which allows operators of oil and gas platforms to take data from multiple radars positioned around the structure and fuse them together to provide one coherent view. The system simplifies operation of the radar and analysis of the data and improves the safety and security of the platform. Also in the category of mature companies is NOTUS

fluid-structure interactions," said company Chief Technology Officer Richard Akers. "There is little data available on the motions and loads associated with floating wind turbines - most research on the fatigue lifetime of floating structures and mooring systems has been conducted on oil and gas platforms which operate in much deeper water and are subject to different loads. The floating wind industry needs to be able to predict the lifetime and maintenance costs of floating wind turbines, especially as related to snap load events and to corrosion degradation."
