The SINTEF Group is the largest independent research organisation in Scandinavia. Every year, SINTEF supports the development of 2000 or so Norwegian and overseas companies via our research and development activity.

The abbreviation SINTEF means The Foundation for Scientific and Industrial Research at the Norwegian Institute of Technology (NTH).

UCDS adapts CRIOP from SINTEF CRIOP User Group

CRIOP is the leading methodology to verify and validate the ability of a control center to safely and effectively handle all modes of operations including start up, normal operations, maintenance and revision maintenance, process disturbances, safety critical situations and shut down.

The methodology can be applied to central control rooms, driller’s cabins, cranes and other types of cabins, onshore, offshore and emergency controllrooms.

UCDS is a Consultancy that carries out CRIOP analysis.


Infotechnics is a leading provider of operational intelligence software solutions.  They specialize in providing operational logging, reporting and action tracking systems which allow their clients to analyze, understand and respond to key business and process data.  Their products are designed for use in dynamic industries where there is a need to capture and make consistent data available at all times. In particular UCDS recommends their Opralog ‘electronic logbook’ software.


Founded in 1994, Process Plant Computing Limited (PPCL) is the brainchild of Dr. Robin Brooks.  Dr. Brooks spent many years studying multi-dimensional geometry and parallel coordinate transformation, before forming the company.

The driving force was the hope to further develop his research and apply it to the process industries of the world.  This research has led to the granting of nine patents and the creation of ‘equation-less’ process modeling.  In turn, this has lead to the integration of process control, quality control and process alarms and the creation of what is believed to be the first-ever general method of calculating values for alarm limits and alerts.

UCDS has in-depth experience in designing control rooms and modifying existing field shelters. Our process is compliant with the ISO 11064 Ergonomic Design Standard for Control Buildings. We interview management, supervision and a significant group of the operators to understand functional requirements, what works well in the existing environment, and identification and correction of problems with the existing design.

Situation Awareness

Abnormal situations encompass a range of events outside the “normal” plant operating modes, e.g. trips, fires, explosions, toxic releases or just not reaching planned targets. In the past incidents such as Piper Alpha, Milford Haven, Flixborough, Texas City and the 2003 northeast electrical blackout have all been attributed, at least in part, to a fundamental lack of good situational awareness. Early work of the Abnormal Situation Management Consortium® included a survey of the US petrochemical industry. Based on their research the consortium estimates industry losses of around $20 billion per year from abnormal situations, approximately equal to the total annual profits of that industry. Furthermore these studies indicate that companies achieving Best Practices in operations can improve productivity by 5-12%. To learn more Click Here


Fatigue Alertness Management

We have many customers looking to enhance their shift handover procedures and follow some of the Recommended Practices identified in the API documents; others are focusing attention on fatigue and fatigue countermeasures. We have great solutions for both these topics. For more details please contact Steve Maddox. To learn more Click Here



User Centered Design Services promotes Behavior – Based Safety which is a process that helps employees identify and choose safe behavior over an unsafe one. Safety in the workplace is a combination of three measurable components – the person their environment, and their behavior. To learn more Click Here

About the Control Room Operator Performance Group

The purpose of this group is to share ideas and solutions that contribute to improving the performance of the control room operator. Abnormal situations can be managed safely and effectively if we provide our operators with the right training, workload, environment, and interfaces.
