Consultancy Services


Our consultancy services cover subsea developments, topsides facilities and onshore reception terminals across the entire project lifecycle with a particular focus on Front-End including Feasibility, Conceptual, and FEED stages.

Our capability includes Greenfield and Brownfield developments, especially integration and tie-in solutions to existing facilities and overcoming the complex challenges faced by Operators on maturing fields and aging infrastructure.

We use our streamlined screening processes to evaluate options using key project commercial and technical drivers. Our approach ensures multi-discipline input at the earliest stages of the design process, building-in detailed operational and constructability knowledge to provide robust solutions and a clear understanding of project cost, schedule and risk.

We have a simple approach to delivering consultancy and advisory services, to provide our clients with innovative and optimised solutions at minimal cost and maximum added value.

Our brownfield experience and use of advanced scanning technology significantly reduces options screening times and study costs. Process designs are validated with minimal engineering and design effort using our streamlined applications.

Piping tie-ins, equipment layouts, line routings, structural steel and overall destruct/ construct requirements are modelled in 3D at a fraction of the cost of traditional methods. This enables material take-offs to be automatically generated for fast accurate cost estimating.

The upshot is that brownfield concept selection and options screening is performed quicker, takes fewer manhours and produces more robust cost estimates.

Project Lifecycle

Our consultancy specialists can support your asset across its entire project lifecycle, covering:

  • Feasibility & Conceptual
  • FEED
  • Detailed Engineering
  • Operations Support
  • Decommissioning

We have the capacity to handle a broad range of project sizes and have the necessary resources and capability to move seamlessly from one project phase to the next.

Please feel free to contact us for further details in each of these areas.



Our experience covers the breadth of onshore and offshore oil & gas facilities, including:

  • Subsea Systems and Infrastructure
  • Pipelines & Risers
  • Topsides Facilities
  • Fixed Platforms/ FPSOs
  • Onshore Reception Terminals

Additionally, our methodologies and efficient delivery are easily transferable to other industry sectors, for instance, we have provided engineering and consultancy services to several new-build whisky distilleries in Scotland.


Specialist Services

Our specialist services capability covers design, engineering and subject matter expertise in a broad range of discipline areas and specialisations, including but not limited to the following:

  • Multidiscipline Facilities Engineering
  • Technical Safety
  • Safety Case Impact Assessments
  • Risk/ Uncertainty Evaluation
  • Flow Assurance
  • Stress Analysis
  • Metallurgy/ welding
  • Structural Analysis
  • 3D Realisation & Animations

We carry a suite of industry standard software applications, standardised in-house calculations and various processes and systems that support our efficient and cost effective service delivery.


Concept & Feasibility

Feasibility & Conceptual Engineering is a core business area for Step Change Engineering. It is a key contributor to field development planning and requires experienced engineers with depth and breadth of knowledge who are able to challenge convention when needed. This early stage of field development planning can be complex with solutions driven by many variables and constraints such as reservoir engineering, drilling, subsea infrastructure, topside facilities and economic drivers. For this phase of work we apply our best minds provide a team with the correct knowledge base, skill and expertise to integrate with our clients and provide the following core services:

  • Concept Selection
  • Process and Flow Assurance
  • Multi discipline input as required for topsides facilities and subsea infrastructure
  • Cost Estimation
  • Project Planning
  • Risk Assessment

Using our expertise we can quickly develop a wide variety of field development options ranging from tie-backs to existing assets to extended well test facilities using new and innovative production and export systems.


Front End Engineering Design

Step Change Engineering has a proven track record of managing and delivering quality FEED studies that allow projects to be sanctioned with confidence.

We provide skilled personnel to ensure the FEED phase starts and continues as a seamless transfer from the conceptual engineering phase. Our experience across all phases of the asset lifecycle ensures that the design encompasses constructability, commissioning and operations requirements in sufficient depth to minimise any “unexpected surprises” during project execution. Step Change Engineering can offer an unrivalled array of expertise available “under one roof”.

We support post- FEED project phases such as detailed design, procurement, implementation and operations support through our other core business areas.
