Overview

Offshore Oil & Gas Infrastructure covers the engineering, construction, installation, and services for offshore production — subsea systems, platforms, floating production (FPSOs), pipelines, and subsea umbilicals/risers/flowlines (SURF). It is led by offshore engineering and equipment specialists (TechnipFMC, Subsea7, Saipem, NOV), serving deepwater and offshore developments.

Demand is driven by offshore (especially deepwater) project sanctioning, which rebounded with higher prices and the appeal of long-life, lower-carbon-intensity barrels. It is a consolidated, highly engineered, capital-intensive segment with long project cycles, and is also pursuing offshore wind and energy-transition infrastructure; offshore activity is recovering after years of underinvestment.
