Some reservoirs are located under 2,000 meters of water and have to be drilled through another 2,000 or so meters of salt. Although exploration challenges have been daunting, production challenges are no less formidable. With a number of production and injection wells placed over the large reservoirs, the difficulty of reliably and safely bringing the oil and gas to production FPSOs have been compounded by the extreme water depths involved.In 2011 Subsea 7 was awarded a milestone

Johan Sverdrup Drilling Platform Installed

The 22,000-tonne topside for the drilling platform was lifted into position in one single lift on the Johan Sverdrup field last weekend. Equinor and the Johan Sverdrup partners are the first users in the world of this ground-breaking technology.On Thursday, May 31, the topside for the Johan Sverdrup drilling platform sailed from the Aibel yard in Haugesund to Bømlafjorden at Stord.Here the 22,000-tonne steel structure was transferred from the barge to Pioneering Spirit, the world’s biggest heavy-lift vessel. All set for the 11-hour journey to the jacket waiting for its topside on the

JW Fishers Pipe Tracking Made Easy

What do modern day people and ancient Egyptians have in common? You guessed it; underground piping! It has been discovered that the very first metal piping can be traced back thousands of years to copper pipes buried and used by Egyptians to carry wastewater. The first manufactures of modern metal pipes, however, first appeared well over a century ago in Great Britain. No matter what material is used to manufacture buried or undersea piping, keeping track of these complex systems has been a challenge from the very beginning. The Global Positioning System constellation of satellites revolutionized

Valeport Unveils New Probe

A new probe that combines the power of the SWiFT SVP and a turbidity sensor has been launched by British oceanographic and hydrographic instrument specialist Valeport. The new SWiFTplus uses Valeport’s high accuracy sensor technology which incorporates turbidity observations with sound speed, temperature and pressure sensor technology to also provide computed conductivity, salinity and density. This is coupled with Bluetooth connectivity and a rechargeable battery.The handheld profiler, constructed from Titanium, has been designed from the outset with the intention of a seamless workflow and has

Efficient Cable Installation Slashes Emissions at Johan Sverdrup

The laying of the cable supplying Johan Sverdrup with power from shore started last week. This helps make the North Sea giant one of the oil and gas fields with the lowest CO2 emissions worldwide.On Wednesday last week the cable-laying vessel NKT Victoria began laying the cables that will supply the Johan Sverdrup field with power from shore.The starting point was the Johan Sverdrup converter station at Haugsneset near Kårstø, and by the end of May the vessel will have laid nearly 200 kilometers of power cables out to the field in the North Sea.Bundled with the power cables, a fiber-optic

Rovco to Launch Live 3D Subsea Technology

Subsea services company Rovco said it is set to launch its advanced live 3D subsea survey system.Following two years of extensive research and development activity, the new technology will begin field trials this month. The system has been developed to effectively manage the increasing complexity of subsea operations, using real-time 3D vision and AI data analysis to cut the cost of underwater inspections and maintenance.The launch is made possible by a £1.2 million ($1.6 million) investment from three U.K.-based investment houses, Green Angel Syndicate, Cambridge Angels and Bristol Private
