Offshore/subsea systems

By adding this latest EPCI contract for pipelines and cables to earlier awards, McDermott is now responsible for all offshore infrastructure associated with Qatar's massive North Field Expansion.

This work presents the results of several failure analyses of gas lift valves retrieved from subsea wells that were unable to prevent backflow from tubing to annulus

The field's massive FPSO is anchored in place and on schedule for first oil prior to year-end.

Subsea tieback in the Central North Sea expected to produce 20,000 BOED at peak, boosting output to Alvheim FPSO.

Since the late 1930s, the offshore industry has advanced from the first platform in 14 ft of water to the ultradeepwater 20K era. Driven by seismic, drilling, and development breakthroughs, the industry has pushed into deeper waters, high-pressure reservoirs, and new frontiers like Guyana, continually expanding the limits of offshore exploration.

This paper presents an automated underwater robot and a nondestructive testing eddy-current probe for alternating-current field measurement analysis of jacket main welds.

The goal of the project described in this paper was to test the added value of shear-wave velocity interpreted from underwater multichannel analysis surface waves, particularly as a propagation tool of geotechnical information.

This paper describes the design of compact carbon-capture modules, including post-combustion CO₂ removal process technology, for applications on offshore facilities.

Chevron looks into using remotely operated vehicles to scrub marine growth from subsea structures.

At peak, annual production from the two fields offshore Italy is expected to reach 1.5 Bcm.
