Odfjell Oceanwind aims to Help Decarbonize Offshore Drilling with Floating Wind

Drilling to be able to drill wells with zero emission, and having MOWUs was one way for us to get there. We have access to all the [Odfjell Drilling] experience, all the harsh environment, all the engineering expertise, when it comes to all facets of designing, owning, operating harsh environments, steel structures. So we can piggyback on all that learning.What are the financial drivers to adopt this technology?In Norway, the authorities have said that the companies that emit pay high CO2 taxation. The intention is to create a positive business case for making these investments. So in Norway, there is

and future void in the market.”XLCC said it has teamed up with Salt Ship Design to develop the basic design of the vessel while working toward the selection of a shipyard to build it. The design has been developed from basic design stage in 3D engineering software for best definition of steel structures and interiors arrangement, the company added. Operational aspects of the cable handling have been studied in collaboration with MAATS Tech and Global Marine.Tor Henning Vestbøstad, sales director of Salt Ship Design, said, “The design is now matured to the level ready for pricing

Companies in Shetland currently manufacture blades, steel structures and provide vessels and services for Nova. The turbines will be manufactured at Nova’s facility in Edinburgh," the company said.Nova’s tidal turbines sit on the seabed, so there is no visual impact on the land and seascapes of Shetland, with ships free to pass above them.

have been contracted to supply six sets of leg mating units and the same amount of deck support units.”   Trelleborg’s leg mating units (LMUs) make a floatover transition possible by damping the forces created as the topside’s load is transferred to the jacket. Consisting of steel structures filled with elastomeric pads, the LMUs are designed to take up the static and dynamic forces of the topside structure, as well as the horizontal forces due to open sea motions during installation. The assembled LMU can be installed either on the topside or substructure. In addition, deck support

Foster Wheeler Wins Contract For Retrofit-SCR System

2014. Commercial operation of the SCR system is scheduled for October 2015. Foster Wheeler will design, supply, erect and commission the selective catalytic NOx reduction system for the Naantali 125 MWe pulverized coal fired boiler (unit 3). The supply includes a new SCR reactor with catalyst and steel structures, ammonia water storing and feeding system, flue gas ducts and new ID-fans. “This retrofit-SCR project awarded in Europe is indicative of Foster Wheeler’s competitiveness in environmental technology in the region,” said Tomas Harju-Jeanty, Chief Executive Officer of Foster
