McDermott Closing CB&I Deal

;s chief executive officer who this week met with Saudi Aramco executives in Houston, said on Tuesday the kingdom "is going to be a big part of our future. It always will be, for both McDermott and CB&I."Last year, McDermott signed a memorandum of understanding with Aramco for a marine fabrication complex at Ras Al Khair. With the exception of an existing fabrication facility, McDermott's dealings with Aramco are focused so far on offshore, upstream partnerships.The offshore sector was hard hit by the 2014 downturn in global oil prices, and while prices this year have recovered

Three weeks later, the third and final main module followed suit on the Dockwise Mighty Servant 3. Once the vessels had safely arrived at the destination in the North Sea, all the pieces of the platform puzzle were lifted in place by the heavy-lift vessel Thialf of Heerema Marine Contractors. Ståle Nordal, Statoil’s project manager for the riser platform, is very pleased to see the platform fully assembled at the Johan Sverdrup field. The construction has been a success in terms of time, cost and quality, but also in terms of safety. All in all, the construction

Taiwan: The Next Battleground for Offshore Wind

Taiwan is becoming the next battleground for the world's top offshore wind developers as they seek a foothold in Asia for a technology that has been expanding fast in Europe.Taiwan announced results on Monday of its first major offshore wind farm auction that aims to add 3.8 gigawatts (GW) of capacity to its existing network of just 8 megawatts (MW).The island's offshore wind market is expected to expand to 5.5 GW by 2025, and the government aims to invest $23 billion on onshore and offshore wind projects by 2025, law firm Jones Day says.Taiwan is making a big push to attract investments in

Shifting to remote-controlled, operated and self-healing rigs and shipsHuman error accounts for an estimated 75-96 percent of all ship losses and marine casualties. As offshore vessels operate within a ‘zero tolerance’ atmosphere for health, safety and environmental incidents, reducing the possibility for human error through increased automation is a crucial avenue for the industry to explore.Moving towards remote-controlled vessels with
