Challenges of Underwater Structure Monitoring for Offshore Operations

years, CCS appears to be one of few effective, large-scale options at the time of writing.Photo: AshteadDMS for offshore operations and communicationsIn September last year, Ashtead Technology completed a two-part subsea installation monitoring project for client Ocean Installer AS in the Northern Norwegian Sea. The company supplied its DMS to monitor the installation of 15 Integrated Template Structures (ITS) in total, located in Equinor’s Askeladd and Johan Castberg fields.Combining powerful software with modular technology, the DMS was deployed alongside supporting technicians over the two

OneSubsea, Subsea 7 Win Ormen Lange Contracts

Schlumberger said its subsea technologies division OneSubsea has secured a frame agreement with A/S Norske Shell for an engineering, procurement, construction and installation (EPCI) contract for the supply of a subsea multiphase compression system for the Ormen Lange field in the Norwegian Sea.Through the EPCI contract, OneSubsea and its Subsea Integration Alliance partner Subsea7 will supply and install a subsea multiphase compression system that uses the industry’s only subsea multiphase compression technology. OneSubsea will, in the first phase of the project, do the engineering and design

Ocean Infinity Completes Mohns Ridge Survey

US-based subsea technology and data company Ocean Infinity said it has compleetd an expedition on the Mohns Ridge in the north-western Norwegian Sea, on behalf of the Norwegian Petroleum Directorate (NPD).NPD had been assigned the task of mapping and proving deep sea mineral deposits by the Norwegian Ministry of Petroleum and Energy. Using multiple autonomous underwater vehicles (AUV), Ocean Infinity acquired a total of 3,900 kilometers of geophysical seabed data over the four-week expedition, assisted by experts from Ocean Floor Geophysics (OFG). At the same time, remotely operated underwater vehicles

NPD Completes Seabed Minerals Expedition

The Norwegian Petroleum Directorate (NPD) announced that it has just completed a successful data acquisition expedition on the Mohns Ridge in the north-western Norwegian Sea, using the Seabed Constructor vessel.According to the Norwegian government agency responsible for the regulation of the petroleum resources on the Norwegian continental shelf, during the four-week expedition, the NPD has made several discoveries of previously unknown sulphide deposits, and collected data covering large areas. These deposits include metals and minerals that are important in battery technology, wind turbines and

Remote-Controlled Submersible Fish Farm in Arctic Ocean

Arctic Offshore Farming project is looking for ways to farm fish in a more sustainable manner.The submerged fish pens are less prone to sea lice which have been linked to a decline in salmon production in Norway – one of the top salmon exporters in the world. The offshore farm located in the Norwegian Sea - part of the Arctic Ocean - outside Troms will have a lower environmental footprint.The region is more vulnerable to fierce weather and wave conditions than traditional farms that are located inside the region’s fjords. To counter this, ABB is supplying a pontoon ballast water system that
