About CREA Consultants Limited
Company Profile
Company

CREA Consultants was established in August of 1996 and became a Limited Company in February 1997. Since then CREA has provided advanced engineering analysis and design services to clients worldwide.

CREA aims to provide an on-demand service to our clients designed to either provide the advanced analysis capability or to bolster the client's own in-house team. In whatever manner we provide our services the cost of maintaining the capability when there is not a project to support it is taken away from the client. This is based on CREA performing the work in our own offices using our own facilities, we do not provide on-site analysis facilities management.

Services

Our services span the engineering disciplines with a specific emphasis on structures and mechanical components. We will analyse and design for most application types, however, we specialise in substantiation against hazard and extreme loads. This specialisation means that we provide our services to the Safety Related Industries where it is common practice to prepare a Safety Case to demonstrate that facilities can be operated with a minimum risk. In the UK this is the application of the As Low As Reasonably Practicable (ALARP) principle. Other countries operate similar regimes or apply prescriptive rules. CREA will provide support in these cases too.

Given the industries that we work in we have developed experience in the submission of design and analysis to regulators, and fully support our clients with the regulatory process. We also work within the regulatory environment providing support to the UK MoD Naval Nuclear Propulsion Regulators.

Types of Loading and Response

Our expertise in studying the responses of extreme and hazard loads on structures defines the load types that we are capable of examining. We analyse and design for static and dynamic inertial (physical) loads and steady state and transient thermal loads. We also combine loading regimes, such as identifying the structural responses to thermal loads or fluid flow. This is the concept recently identified as Multi-Physics analysis.

For all loading regimes we will consider both linear and non-linear responses, with non-linearities including the classical material non-linearities along with geometry (P-Delta and large strain) and contact.

Taken together these capabilities allow us to cover a wide range of advanced analysis and design scopes:

Quality Assurance

CREA does not currently operate a certified Quality Assurance (QA) programme; however, we do apply good QA principles to all of our work. The primary reason for not having a certified scheme is that most of our clients have their own QA requirements and it is easier for us to fit into these than to impose our own procedures. We firmly believe that QA is not an overhead on a project if it is applied as a natural aspect of daily working practice, if a QA procedure is apparently leading to an obvious overhead then the procedure and task methodology should be reviewed.

CREA is an active member of the International association for the engineering simulation profession NAFEMS with representation at the highest levels of this important organisation. In addition to NAFEMS we have links with the UK engineering institutions (Institution of Structural Engineers, Institution of Civil Engineers, Earthquake Engineering Field Investigation Team (EEFIT) and Society of Engineering and Civil Engineering Dynamics)) and American Society of Mechanical Engineers (ASME).

Our Clients

CREA Engineers have experience from working in many industries. Projects carried out have included safety and risk studies, and analysis and design to support safety case submissions. This doesn't mean that we restrict ourselves to high technology analysis and design, we have been involved in the design of hoppers, reinforced concrete industrial buildings and temporary works, in addition to nuclear containment plant and oil and gas production facilities. Our clients benefit from our cross industry expertise and our ability to mix skills to solve complex problems. We also maintain contacts with other consultancies in the UK and world wide to enable us to tackle large and diverse projects.

As will be seen from the list below, we have experience in working outside the UK, our engineers have worked on projects in Europe, the USA and much further afield.

The list below consists of a small selection of the clients that CREA's staff have worked for, either in their time with the company or before joining.
