44 ST | December 2018 Sonardyne Nav Tech For Offshore Brazil Ops International subsea services provider DOF Subsea has chosen acoustic and inertial navigation technology from Sonardyne Brasil Ltda. to support its deepwater op- erations from three vessels offshore Brazil. The vessels will be equipped with Sonardyne's SPRINT-Nav sub- sea navigation instrument for under- water vehicles. An ROV on one of the vessels will also be fitted with a Sonardyne Syrinx DVL. DOF Subsea's multiple SPRINT- Nav systems will be used to support ROV operations, as part of con- struction, inspection, maintenance and repair work in Brazil's deep- water pre-salt oil fields, in depths down to 3,000 m. LARS Floating Garage For AUV Fleet UTEC successfully commis- sioned its new launch and recovery system (LARS) for the fleet of seven AUVs it uses for seabed surveys in the oil and renewables industries. The LARS is a floating garage that enables an AUV to be launched and recovered without needing a small boat, thereby simplifying operations and improving safety. It also in- creases efficiency and reduces costs by enabling AUV surveys in parallel with construction or laying activi- ties, as the LARS can be deployed from the same work vessel. The LARS was first used on a pipeline inspection offshore West Africa. Tentative Approval for Alaska Oil, Gas Facility The U.S. Bureau of Ocean En- ergy Management (BOEM) issued conditional approval to Hilcorp Alaska LLC for its Liberty Project oil and gas development and produc- tion plan. If developed, the facility would be the first oil and gas pro- duction facility in federal waters off Alaska. Hilcorp proposes to build a 9-acre artificial gravel island in the shallow waters of the Beaufort Sea, about 20 mi. east of Prudhoe Bay and about 5 mi. off the coast. The facility would be similar to the four oil-and-gas-producing artifi- cial islands currently operating in the area's state waters: Spy Island, Northstar Island, Endicott Island and Oooguruk Island. Decom Project Complete Offshore Middle East Unique Group and Innovo have successfully completed a decom- missioning contract for Saipem on a key offshore platform in the Middle East. Internal and external dredging tools, diamond wire cutting tools and internal cutting tools based on abrasive water jet technology, oper- ating at 1,500 bar, were provided for the project, along with skilled operators to support the operation. Forssea, GMS Joint Lab Forssea Robotics chose GMS as the main technical partner to certify its real-time visual positioning tech- nologies. A joint laboratory will be created to develop a common offer covering camera calibration, sub- sea image treatment and innovative photogrammetry solutions. Forssea Robotics' V-LOC (Visual LOCalization) technology has been designed for quick and operational use. One operator sticks the mark- er on the structure, and the camera computes the 6° coordinates in real time on the user screen. Following offshore tests last April, Forssea de- cided to increase the initial perfor- mance prior to commercialization; to cover more applications, oper- ators quickly asked Forssea to im- prove its system down to 0.1° and 1-mm positioning accuracy at 3-m ROV flying distance. Conversation Series to Open Oil Industry to New Audience Attollo Offshore has released the first of its Attollo Conversation se- ries to help open a discussion to im- prove offshore operations for a new era through constructive disruption and change. The series wants to ad- dress key issues of technology and innovation within the offshore ener- gy industry, including the growing use of smarter technology, the fu- ture of work and big data. One of the most powerful mes- sages that came across during the filming of the series is the need to find ways of transferring the knowl- edge held by the current generation to the next generation while en- couraging change, still controlling major accident hazards, being safe and protecting the environment with improved methods. To take part in future interviews, contact: Permian Token Brings Blockchain to Oil, Gas Sector PermianChain Technologies is introducing the Permian Token (XPR), a crypto asset-class that will underpin holding rights to the val- ue of potential but undeveloped oil and gas reserves. XPR is expected to eliminate the layers of bureaucracy and dramatically reduce broker and administrative fees. It will also make it simpler to pinpoint and alleviate delays, improve investment efficien- cy, and open the sector to a swathe of potential new investors. Trading oil and gas is currently complex, slow and fundamentally inefficient. Agreements are cumber- some and difficult to transfer with- out adding costs, and there are so many different steps involved in the process of getting oil and gas from upstream to downstream, that the knock-on effect of delays can be significant and costly. The levels of complexity and inefficiency mean that many potential investors are re- luctant to involve themselves in the market, reducing the sector's poten- tial liquidity and value. The Permian Token's system of smart contracts would replace these complex agreements using the Perm- ianChain, a blockchain network being developed by Canada-based PermianChain Technologies. There are already approximately 250 mil- lion barrels of potential oil and gas reserves planned to be listed on the PermianChain network. ST offshore oil & ocean engineering
