FEED & Detailed Engineering

Overview

Execution-ready engineering to progress wellhead platforms from concept to delivery.

We provide FEED and detailed engineering services to progress wellhead platform concepts for early investment decision-making and through to execution-ready design. ICON works with operators to develop robust engineering solutions that address structural, foundation and installation requirements for minimal facilities wellhead platforms.

Our FEED and detailed engineering is grounded in offshore execution experience. By maintaining a clear focus on constructability, jackup rig interfaces and installation methodology, we help ensure wellhead platform designs are practical to deliver offshore and optimised for the installation method selected.

Our expertise

FEED and detailed engineering for wellhead platforms and minimal facilities.

Front End Engineering Design (FEED)

Development of FEED packages to define wellhead platform scope, layout, structural loads and interfaces, supporting confident progression to detailed design and execution planning.
Detailed structural and foundation engineering

Detailed engineering of platform substructures, jackets and foundations to support safe installation and long-term structural performance, including pile design, mudmat sizing and conductor supported platform analysis.
Topsides and facilities engineering

Detailed design of topsides structures, deck arrangements, equipment supports and utility systems aligned with minimal facilities platform requirements and operational constraints.
Rig interface and installation engineering

Detailed engineering of rig interfaces, seafastening, installation aids and lift arrangements to support jackup rig-installed platform delivery.
Integration across disciplines and phases

Coordination of multidisciplinary engineering inputs to maintain alignment between FEED, detailed engineering and offshore execution requirements, with ICON’s installation and T&I teams involved from early phases.

Related Capabilities

Full project lifecycle, ensuring safe, efficient, and cost-effective delivery services.

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.

Learn more about Engineering & Design Phases

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.

Learn more about Engineering Disciplines

We manage technical, operational and delivery interfaces. By coordinating interfaces across engineering disciplines, vendors, contractors and offshore execution teams, we help keep design intent and delivery requirements aligned.

Learn more about Interface Engineering & Integration

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.

FAQs

Answers to key questions on our safe, efficient offshore services.

FEED is typically undertaken once a preferred concept has been selected, to define scope, manage risk and provide a robust basis for detailed engineering and execution.

Installability is addressed through execution-led engineering, with installation methodology, rig interfaces and offshore constraints considered throughout design development.

Yes. ICON regularly supports projects through FEED into detailed engineering, maintaining continuity and reducing rework between phases.

Yes. Installation and drilling requirements are integrated into FEED and detailed engineering to ensure designs are aligned with offshore execution and operational needs.
