Oil & Gas

Citec has supplied the energy & power industries with multi-discipline engineering, consulting and information management services for almost 30 years. Oil & Gas is naturally a significant part of the energy industry, and this sector has been the fastest growing sector in Citec the last years. This is due to increased focus on this sector, especially from Citec India, but also through the aquisitions of M7 Offshore (now Citec Norway and Citec Singapore) and Akilea in France.

Today, we have 350 engineers worldwide, specialized in the Oil & Gas segment, making Citec a preferred global partner in the industry. We offer full-scope engineering and information management services directly to oil companies, as well as to oil and gas industry contractors, ship owners, engineering houses, suppliers and operators.

We have process systems as core knowledge, but unlike some process houses we believe in strong participation from other disciplines as automation, structural and layout. Even though we recognize the importance of conceptual knowledge, we also believe that experience from detail engineering, fabrication and completion activities is a vital part of truly understanding what is necessary to deliver a quality product and to be a reliable partner for our Clients.

Director for the Oil & Gas business is Sakari Koivuniemi. Managing Director for Citec in Norway and Singapore is Nils-Erik Hannisdal. The Oil & Gas business in France is headed by Managing Director François Combemorel, and India’s Oil & Gas business is managed by Managing Director Nasir Mulani.

Footprints from our past projects can be seen on a global scale- the geographical locations for these products’ end destinations range from the North Sea, West Africa, Australia, Gulf of Mexico, India, SE Asia to Brazil. Through the delivery of more than 20 FPSOs, 9 FSRUs, 6 FLNG studies, several studies for oil companies and a background from the major North Sea developments, we have gained special expertise and valuable experience.

Our range of experiences is within Project Management, Process Engineering (PFD, P&ID and simulations), Cost & Weight Estimates, Automation (SCD), Instrumentation, Mechanical, Layout (GA, Isometrics), HVACand Documentation Control/ Information Management. Through these experiences,we have established our own project management tools and procedures for project control, planning, interface and engineering control. We contribute with all the required engineering deliveries for construction, and are familiar with all major international standards used within the business.


We carry out high quality engineering tasks within all phases of the project’s development- such as Feasibility- and Concept Studies, Cost & Weight Estimates, as well as FEEDs and Detailed Engineering. The local presence – global resourcing way of working enables us to choose resources from different countries from a cost efficiency or a project execution point of view.

We take great pride in being effective and reliable, and a key principle is a fast track attitude which results in high quality - on time.
