Citec Norway

Citec Norway's offices are located in Asker (outside Oslo) and Sandefjord. Citec Norway employs about 20 persons. Nils-Erik Hannisdal is Managing Director for Citec Norway.

After M7 Offshore became part of the Citec Group in 2013, we are now part of an engineering group with more power. Worldwide, we have 360 engineers who specialize in the Oil & Gas segment, making Citec a preferred global partner in the industry.

We have process systems as core knowledge, but unlike some “process houses” we believe in strong participation from other disciplines as automation, mechanical and multidiscipline layout. Also within Weight & Cost estimation we have recently became a solid player. Citec has developed the market leading weight & cost estimation application Ciesta. We aim to be the preferred partner within any conceptual work (feasibility, FEED). However, we also believe that experience from detail engineering, fabrication and completion activities is a vital part of truly understanding what is taken to deliver a quality product and to be a reliable partner for our clients.

Citec is also a strong contractor within other energy, process and manufacturing segments, and we expect a growth in these segments also in Norway.

 Citec Norway team 10th anniversary

Citec Norway celebrated its 10-year anniversary in August 2016


Footprints from our past projects can be seen all over the globe, the geographical locations for these products’ end destinations range from the North Sea, West Africa, Australia, Gulf of Mexico, India, SE Asia to Brazil. By delivering more than 20 FPSO’s, nine FSRU’s, six FLNG studies, several studies for oil companies and with a background from the major North Sea developments - we have gained special expertise and valuable experience.

Our range of experiences is within Process Engineering (PFD, P&ID, and simulations), Automation (SCD), Instrumentation, Mechanical, Layout (GA, Isometrics), Project Management and Documentation Control. It is through this experience that we have established our own project management tools and procedures for project control, planning, interface and engineering control. We contribute with all the needed engineering deliveries for construction, and we know all major international standards used within the business.


Citec Norway can perform high quality engineering tasks within all phases of the project’s development, such as Feasibility and Concept Studies, as well as FEED’s, Detail Engineering, Fabrication follow-up and Commissioning. As part of the Citec Group we operate on the principle local presence - global resourcing, and cooperate with other Citec countries whenever this is effective from cost or project execution point of view.

We take great pride in being effective and reliable, which is reflected through Citec Norway’s historically solid track record with respect to project execution.

We hold the highest creditworthiness attainable (AAA in D&B). Our key principle is a fast track attitude which results in a high quality - on time.
