Our Services

Worldclass services from top level experts.

Strategic and Technical Consultancy

When we are involved from the start we help our customers to think bigger, start small and scale fast. We collaborate with our clients. We develop and deliver technology strategies which add ultimate value. We enable you to be distinguished from the competition. We value honesty in all our relationships, so if we think there is a more valuable direction, we’ll suggest that too.

Feasibility Study

We do feasibility studies in order to determine whether your project is worth the investment or not.

Conceptual Design

We prepare concept design packages for feasible options typically determine the overall frame work of the project.


We study the selected concept and define and detail it further to come to a “design basis” and scope of work (SoW) for FEED.

Models and Simulations

We create mathematical models and simulations of your processes for securing your investments operational cost in advance.

Technical Analyses

We do technical analyses of your projects in order to make sure you select the best avaiable technology for your process and properly integrate all components.

Commercial Analyses

We do commercial analyses of your projects in order to make sure you buy the best product at its value and define the payback time of your invesments.

Our experience driven solid process

Feasibility Study

The feasibility study is the first phase of an engineering project. Its main objective is to determine whether the project is worth the investment for the owner/client. This could be new development or extension of an asset (greenfield and brownfield projects) – for example a refinery, FPSO, offshore wind park, solar farm, carbon capture & storage, mine, or infrastructure.


A feasibility study helps determine if the project is viable and justifiable. Not only technical and economic feasibility is evaluated, but also legal, planning, and operational feasibility, as well as an assessment of the project’s environmental, social, economic and political impacts.


The duration of this project stage depends on the nature, location, size and complexity of the project. Completing this stage is a key milestone for any project and the gateway to the Conceptual Design stage (or: Concept Definition). Not all project ideas turn out to be feasible or viable, which is exactly why this stage is so important.

Conceptual Design

The Conceptual Design stage – sometimes ‘Concept Selection’, ‘Conceptual Engineering’ or ‘FEL-1’ (if FEL project planning is used) – starts after a positive outcome of the Feasibility Study: the project seems technically achievable and commercially viable. This next stage marks the start of the design process, and the three subsequent stages (Pre-FEED, FEED /Front-End Engineering Design, Detailed Design) will each go a level deeper, expanding the design with more details and more accuracy.


In this stage, engineers analyze the engineering challenge to come up with (realistic) requirements and solutions. First, design ideas are generated on how the project could be implemented (‘ideation’). Next, gathered design ideas and alternatives are evaluated (‘concept evaluation’) – on their strengths, weaknesses, cost and benefits – to decide on the optimal solution, which meets the requirements and maximizes profits for the client/owner. Cost estimates (on CAPEX/capital expenditures and OPEX /operational expenses) are still quite rough at this stage: easily +/- 50%.

Key deliverables & outputs:


More types of deliverables are produced now by qualitative and quantitative engineering analyses, design activities, cost estimation, studies and meetings.


Typical deliverables of this stage may include:


- Functional requirements (FR)

- Preliminary design basis

- High-level design drawings and diagrams (e.g. plot plan)

- Models and simulations (e.g. thermal simulation)

- Technical analyses (e.g. mechanical/structural)

- Commercial analyses (economics/financial)

- Risk register


Typical deliverables for projects involving (chemical) processes:


- Block Flow Diagram (BFD) – A simplified and more informal overview than a Process Flow Diagram (PFD), providing a high-level logical overview of the process structure and streams.

- Material Balance – Overview of materials involved (input and output).


The pre-FEED stage (pre-FEED is short for preliminary Front-End Engineering Design) – sometimes referred to as ‘Design Basis’ or ‘FEL-2’ phase (if FEL project planning is used) – comes after Conceptual Design and before the FEED stage. It is the final part of conceptual engineering. The selected concept will be defined and detailed further to come to a “design basis” and scope of work (SoW) for FEED.


By the end of pre-FEED, key design decisions have been made, risks are clear and mitigated where needed, there is a clear approach for the execution phase, and cost estimates are more precise (CAPEX +/- 30%). Engineering is often 4 to 8% complete by that time. The duration of this stage varies depending on the nature, location, size and complexity of the project.

Key deliverables and outputs:


The two main deliverables of the pre-FEED stage are:


- Basis of Design (BOD) document (lists the principles, requirements, criteria, assumptions and reasoning on which design calculations and decisions are based)

- FEED Scope of Work (SoW) (summarizes the project scope, schedule & objectives, interfaces, and the work to be done by the FEED contractor)

Other typical deliverables of the pre-FEED stage include:


- PFD drawings (Process Flow Diagrams; high-level process overviews, more detailed and formal than a Block Flow Diagram (BFD) from Conceptual Design, and less detailed than a P&ID drawing)

- Heat and Material Balance, or Heat and Mass Balance (HMB; process overview with major equipment and amount of heating/cooling required, normal operating conditions and flow rates of process streams)

- Initial P&ID drawings (Piping & Instrumentation Diagrams; process overviews with all crucial equipment, piping and instrumentation)

- Preliminary plot plan or field architecture

- Main equipment list

- Economic assessments (CAPEX, OPEX, ABEX = abandonment expenditure)

- Start of EIA or ESIA (Environmental (and Social) Impact Assessment)

- Risk mitigation plans

- Enhanced project schedule
