Engineering & Design

Overview

Engineering and design support for modifications to live offshore assets.

ICON delivers brownfields engineering integrated with high accuracy digital survey and installation led design to support upgrades, tie-ins and life extension works on live facilities.

We work alongside operators to develop safe, practical and constructible solutions that can be implemented within active operations.

Engineering is shaped by installation sequencing, access constraints and interface complexity defined early in the project lifecycle. By addressing lifting limitations, shutdown alignment and constructability during design development, we reduce late-stage change and minimise offshore rework.

We support scopes across fixed and floating production facilities covering both permanent modifications and temporary works required for safe installation in live environments.

Our expertise

Engineering and design support for offshore brownfields projects.

Concept and feasibility engineering

Early phase engineering to assess options and develop practical brownfield solutions, informed by site conditions and where available digital survey data.
FEED and detailed design

Development of brownfields concepts through FEED and detailed engineering, ensuring designs are constructible and execution-ready.
Tie-in and modification design

Engineering for structural, mechanical and piping modifications, ensuring interfaces with existing facilities are well understood and de-risked prior to offshore execution.
Design support for offshore execution

Engineering input to support offshore installation, modification and commissioning activities, including resolution of site queries and changes.

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 combine high-accuracy 3D scanning with in-house drafting, modelling and visualisation to turn site data into usable engineering input. Point cloud data supports as-built modelling, clash detection, interface verification and detailed structural, mechanical, lifting and installation design.

FAQs

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

Yes. We support both permanent modifications and temporary works needed to install, access or execute brownfields scopes safely on live facilities.

We develop tie-in designs around actual facility constraints, existing interfaces and installation requirements so modifications can be executed with fewer surprises offshore.

Yes. We can work with available asset information and, where required, integrate survey or scan data to improve design confidence and reduce interface risk.

Yes. We can continue through offshore execution support, including responding to site queries, managing change and helping keep work aligned with design intent.
