Offshore/subsea systems
The company has installed an autonomous drone system on Aker BP’s Edvard Grieg platform in the North Sea, enabling frequent, remote inspections from shore.
This paper describes the use of coiled tubing in a pilot project for carbon dioxide injection, enabling evaluation of the conversion of an existing oil field for CCS purposes and derisking storage-development uncertainties before having to cease hydrocarbon production.
This paper describes the first riserless coiled tubing services operation performed in a live subsea well and the associated improvements in efficiency, cost savings, and safety.

Subsea advancements in the works include longer tiebacks, an underwater drone that lives on the seafloor, and a robotic manifold capable of actuating dozens of valves. Do these new capabilities, born of necessity, signal a sea change in industrywide technology development? -
The company’s new approach is designed to cut the time required to generate optimal subsea field layouts.
