Overview
We provide concept development, detailed design, engineering services and supply of subsea structures and systems. Our work spans the full scope from early design through to fabrication-ready deliverables and offshore installation support, covering both engineered-to-order structures and ancillary equipment for subsea construction and intervention campaigns.
Our expertise
Flexible and riser support systems that consider operational, inspection, maintenance and decommissioning requirements and offshore constraints.
Detailed design of subsea structures and systems with a focus on fabrication, installation and long-term operability considerations.
Design and supply of pipeline end terminations, pipeline end manifolds and flowline end terminations for inline and flexible connected applications, including installation and hook-up procedures.
Design, engineering and supply of mid depth buoys and mid water arches for riser and flowline support, including gravity mat foundations and offshore installation support.
Structural design and supply of riser bases to support rigid and flexible riser systems, with consideration of seabed conditions, installation method and long-term integrity.
Design and supply of subsea pig launcher and receiver landing and levelling systems, including installation procedures and hook-up support.
Detailed design and supply of inline and flexible connected manifolds and pipeline end structures, including installation, hook-up and pre-commissioning procedures.
Engineering and delivery support for subsea drilling templates and protective structures designed to suit a range of seabed conditions, drilling methodologies and client requirements. Engineering to support high accuracy installation of subsea templates, accounting for future jacket installation tolerances, docking pile interfaces and tie-back requirements.
Design and supply of suction piles and suction cans for platform foundation and BOP tethering applications, including installation analysis and procedures.
Engineering and supply of Xmas tree handling equipment including bespoke spreader beams, cart modifications and deck interface solutions to support safe tree running operations from MODUs.
Design and supply of ROV landing and receival skids, anode skids, parking stands and other ancillary subsea structures to support offshore construction and intervention campaigns.
Related Capabilities
ICON maintains a dedicated in-house project management capability that supports offshore and onshore energy projects from early definition through to execution and close-out.
Our commercial studies are developed alongside engineering and execution planning, so cost, schedule and risk assessments reflect practical delivery realities rather than theoretical assumptions.
We deliver practical, fit-for-purpose solutions across feasibility, concept, FEED and detailed design. Our engineering is aligned with installation methods, construction sequencing and offshore constraints so designs can be delivered safely and efficiently.
Our disciplines work together to deliver integrated, practical solutions aligned with offshore execution requirements. This structure helps us manage interfaces internally, reduce reliance on third parties and maintain technical continuity from early definition through to execution readiness.
We manage fabrication activities, including work completed at third-party yards and within ICON’s own yard facilities. This helps ensure structures, equipment and assemblies are delivered in line with approved designs, specifications and quality requirements.
We support inspection, maintenance and repair scopes that help extend asset life, address integrity issues and maintain safe operation.
