ICON's annex platforms offer a cost-effective way to bring near-field discoveries into production using shared production facilities.
Brownfields
Overview
Construction-led engineering for safe, efficient modification of live offshore assets.
ICON delivers construction-led brownfields engineering and execution support to safely modify, upgrade and extend existing offshore assets. Our approach starts with how work will be installed offshore ensuring engineering solutions are practical, constructible and aligned with the realities of operating facilities.
Our teams work across fixed platforms, FPSOs and offshore facilities, integrating multidisciplinary engineering with installation methodology development, temporary works design and execution planning. Early engagement with asset and operations teams allows ICON to understand access constraints, lifting limitations, shutdown windows and SIMOPS requirements before designs are finalised.
Brownfields delivery demands more than sound engineering.
It requires a deep understanding of how work will be executed in a live environment. ICON works closely with operators to develop fit-for-purpose solutions that balance technical assurance, constructability and operational impact, supporting efficient execution from concept through to offshore implementation.
ICON provides flexible brownfields support across the full project lifecycle, from early feasibility and concept definition through to EPCM delivery and offshore execution support. Services can be delivered as discrete engineering scopes or as integrated, execution-aligned packages tailored to shutdowns, tie-ins and live operations.
