Interface Engineering & Management

Overview

Interface definition and coordination for offshore modification and execution scopes.

We provide interface engineering management services to support offshore drilling rig and vessel modification projects. ICON helps operators, rig owners and service providers manage technical and operational interfaces to reduce risk, avoid rework and support safe offshore execution.

Our interface engineering approach is grounded in offshore delivery experience. By integrating into our client teams, we identify, define and manage interfaces early, helping ensure engineering and execution activities are aligned with real operational constraints and stakeholder requirements.

Our expertise

Interface engineering management for offshore rig and vessel projects.

Interface identification and definition

Systematic identification and documentation of interfaces between structures, equipment, systems and stakeholders.
Interface register development and management

Development and ongoing management of interface registers to track responsibilities, approvals and resolution status.
Technical interface coordination

Coordination of technical interfaces across disciplines, contractors, service providers and certifying authorities.
Deck layouts and third party equipment interfacing

Development of deck layouts and interface engineering for third party drilling, completions, subsea and well test equipment onto MODUs and support vessels, including deck loading calculations and space envelope checks.
Deck assessment and strengthening

Structural assessment of MODU and vessel decks to confirm capacity for proposed equipment layouts, with engineering support for strengthening works where required.
Seafastening and grillages

Design and engineering of seafastening arrangements and grillages for the secure transport and deck mounting of equipment on MODUs and offshore vessels.
Engineered lift plans and sequencing

Development of engineered lift plans and installation sequencing to support safe and efficient offshore execution within rig and vessel constraints.
Temporary and permanent piping design and installation

Design and engineering of temporary and permanent piping systems to support modifications, equipment installations and operational requirements on MODUs and offshore vessels.
Offshore execution interface support

Support during offshore execution to manage interface changes, resolve issues and maintain alignment with approved designs.

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.

We support operations and maintenance work with engineering input, planning support and execution coordination.

Learn more about Operations Support

We manage storage of equipment, materials and components so they remain protected, traceable and ready for use at the right stage of delivery.

FAQs

Answers to key questions on our installation and execution services.

ICON supports the offshore execution of brownfield modifications and upgrades end-to-end, from installation planning and workpack development, through offshore engineering supervision and trade labour, to verification and close-out documentation.

Both. ICON supplies direct labour trades to execute the works, often supplementing existing rig crews to minimise POB pressure, alongside engineering oversight to resolve site queries and manage change.

Through early definition of construction constraints, integration of survey data and constructability-led design, so installation planning reflects actual site conditions before work begins offshore.
