Advanced engineering solutions

Our centres of engineering excellence provide advanced engineering services with specialist capabilities that cover a range of applications for both new and existing assets. 

Our services are intended to minimise the risks that our clients face, and to maximise the return on their investment.

We work onshore and offshore, in support of FEED execution, EPC and operations support, and also deliver standalone services and studies as needed.

These services include:

Flow assurance

A steady flow from reservoir to processing facility is vital to the effective operation of any production transport system, and this flow has to remain reliable throughout the life of the field.

Our understanding of flow assurance - reservoir behaviour, fluid chemistry, production profiles and solids deposition - means we can help you achieve those reliable flow rates.

And we can offer more than the basics. We have additional expertise in tubing, flowline and pipeline diameters, insulation, trenching with back-fill, and operation limits. This means we can offer flow assurance services from project concept to FEED, and through to detail design, commissioning and operation.

Our flow assurance services include:

  • direct electrical heating
  • steady state and transient multiphase modelling of single pipelines and networks
  • dynamic modelling of integrated facilities
  • slugging assessment, mitigation and control
  • hydrate risk management
  • wax risk management
  • production chemistry
  • corrosion and erosion analysis
  • compositional tracking analysis
  • solids transport assessment
  • and development of operating philosophies into operating procedures

Our analysis is used to determine a facility’s operating approach. It lays the foundation for robust operating procedures for all production modes throughout the system life cycle, including start-up, normal operation, rate change, and shutdown.

Dynamic simulation

Dynamic simulation is critical to the success of our projects - and to reducing risk and improving return of investment - and so it is a vital part of our technical integrity programme.

Steady state simulations give an idealised snapshot view of flow rates, pressures and temperatures, and are useful as a basis for process design.

Dynamic simulation, however, considers the behaviour of equipment over time, which means we can identify and resolve potential problems, such as equipment design constraints, hydraulic limitations, control system interactions or transient condition issues.

Our highly skilled dynamic simulation specialists conduct simulations ranging from small studies of specific unit operations to high-fidelity, detailed models of complete process plants, and including:

  • dynamic compressor studies
  • control scheme design validation
  • start-up procedure development
  • analysing the transient response to process or equipment failures
  • depressurisation / relief studies
  • establishing process flexibility
  • novel design testing
  • utility system design
  • commissioning assistance

Flare system studies

Burning off flammable gas is essential for the safety and integrity of any facility, whether onshore or offshore, and wherever it is in the world.

Many facilities need to flare these waste and unusable gases, either as a short-term measure, or as part of the overall production process.

Designing, building and operating safe and effective flare systems is therefore a vital part of plant design and operation, and is essential to mitigate the risk to people and facilities.

We have experience of working with flare systems across the full life cycle of a plant:

  • new facilities: system design, engineering, procurement and commissioning
  • installed systems: we appraise installed systems that will be revamped or modified under new operating and design conditions

We are familiar with conducting relief and blowdown system analysis in accordance with APE 520 / 521, and with client-specific standards.

Every facility is different, but our team of engineers are highly skilled and able to develop a set of risk scenarios that fit each case. They will then carry out a full range of relief valve calculations and simulations.

We use FLARENET to simulate the flare systems we are working on. This helps identify potentially dangerous relief scenarios, and supports our engineers as they evaluate potential design solutions.

Potential steps to be completed include:

  • flare recovery unit design
  • a review to justify and revalidate installed relief valve set pressures
  • completion of complex blowdown calculations for fire zone sectionalisation
  • appraisal of existing relief and blowdown systems for modifications in line with international and/or client codes and design standards
  • review of vendor documentation and liaising with flare tip and stack vendors to address case specific details


Rotating equipment and controls

Our clients demand the best from their equipment. In order to help them achieve this, we offer high-fidelity modelling of compression systems, whether this is for a simple single stage unit or for multi-stage parallel trains integrated within the surrounding process units.

This service covers:

  • simulation/emulation of load sharing/load balancing
  • master performance and anti-surge controls
  • compressor performance verification under transient conditions
  • modelling driver performance with appropriate inertia, constraints and operating characteristics
  • simulation of turbo-expander recompressor units within NGL extraction process systems
  • complex control schemes and sequencing modes

Our rotating equipment specialists have worked around the world, in the UK, Norway, North Africa, the Middle East, and many other countries.

And they’ve worked with equipment including:

  • process gas compressors (dynamic and positive displacement)
  • process and utility pumps (dynamic and positive displacement)
  • electrical power generation plant
  • prime movers (combustion gas turbines, steam turbines, electric variable speed drives and electric fixed speed drives)

For example, we have extensive experience in the front-end engineering design and purchase of process gas compressors for projects involving discharge pressures ranging from circa 20 bara (propane refrigeration) to over 500 bara (natural gas reinjection).

Finite Elemental Analysis

Any component that operates under stress can suffer from fatigue and, ultimately, failure.

And the components in the facilities we work with are typically under stress day in, day out, due to the nature of the work they do.  The risks to the facility - and therefore to the people who work in it - are obvious.

We use our expertise in advanced analysis to ensure the integrity of these structures and components. In particular, we use finite element analysis to provide solutions to engineering problems across the oil and gas industry (as well as other industries that demand high integrity).

Our analysis techniques apply to every stage of the project life cycle: from concept through FEED to detail design, operation and decommissioning.

Our projects range from jackets subject to environmental loads through to rolling element bearing under operating loads.

Our engineers use Abaqus, which is widely used across the oil and gas industry, and which has an unrivalled reputation for quality and reliability.

The combination of Abaqus with our advanced analysis and the expertise of our experienced structural engineers means we can provide you with the best possible solutions.

We are typically called on to help our clients with:

  • fatigue analysis
  • ultimate strength analysis
  • dynamic analysis (for example, impact and blast)
  • failure analysis and investigation
