Oil & Gas

Decades of worldwide experience. Our Offshore project track record covers a large number of geographical areas from the North Sea, West Africa, Australia, Gulf of Mexico, India, SE Asia to Brazil. Our extensive Onshore projects range from LNG terminals to refineries, from upstream to downstream.

Full-scope services through the entire lifecycle

Citec believes in working in a safe work environment. We are committed to provide safe and sustainable solutions in all of our activities throughout the entire project lifecycle.

Our 300 Oil & Gas specialists worldwide providing early phase studies, full-scope multi-discipline engineering, information and project management services. Backed up by our 1000 colleagues in Citec Group, we are able to mobilise large project teams across both disciplines and geographical borders.

We offer full-scope of multi-discipline engineering, information and project management services directly to oil companies, as well as to oil and gas industry contractors, ship owners, engineering houses, suppliers and operators.

We have a portfolio of special services and unique solutions for both greenfield and brownfield projects which result in increased efficiency and reduced cost for an operator at any stage of the project, that is, from pre-feasibility and front-end to construction and operation stages. This Citec value engineering approach is well documented by our references from projects performed for major oil & gas operators.

Let Ciesta handle your Weight & Cost estimation

The current low oil prices put increasing pressure on future investments in oil and gas fields. Profitable investments require better estimates of projects in early phases. There is also an increasing need to analyse a larger set of project design combinations. Ciesta is a software application for weight and cost estimates for offshore fields designed to meet these demands.

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 25 FPSOs, 11 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 experience is within Project Management, Process Engineering (PFD, P&ID and simulations), Cost & Weight Estimates, Automation (SCD), Instrumentation, Mechanical, Layout (GA, Isometrics), HVAC and 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.


We are able to undertake small and large projects with high efficiency and successfully compete with larger contractors due to our lean organisation with short decision lines globally and locally; ability to act as a big company but maintain flexibility of a small one.
