Pipeline engineering & design

Pipeline engineering - FEED

With more than 35 years as a leading and innovative Subsea Engineering Provider, IKM Ocean Design are proud to offer  highly competent Senior Pipeline Engineers in our offices in Stavanger, Trondheim and Oslo. Our expertise is pipeline design, including advanced analyses and geotechnical support.

Our engineers are specialists in umbilical, riser and flowline engineering (SURF). IKM OD design offshore pipelines, ranging from routing and wall thickness calculations, to complex finite element inplace analyses for free spans, expansion and buckling and installation. Our Company follows all phases of the project, from Concept Studies and FEED to Detail Engineering and Life Extension Studies.

IKM Ocean Design have over the last years worked in close cooperation with the industry to develop and improve new and cost-effective technical solutions by challenging industry practice and regulations. Optimization of pipeline protection requirements and optimization of free span rectification requirements has saved our Clients hundreds of MNOK. Our Company always work to improve our design and be ahead of our competitors with the latest technology. 
In cooperation with our largest Client, Equinor, Structural Reliability Analysis (SRA) methodology has been used for trawl fishing loads in free spans (Johan Castberg). 
At Johan Sverdrup, the Residual Curvature Method (RCM) has been applied to control expansion and buckling. Approximately 28.5 km of 16” Water Injection pipelines was successfully installed with a total of 22 residual curvature sections.

IKM Ocean Design has a geotechnical group of engineers that performs activities such as geotechnical survey scope, offshore support, pipe – soil interaction definition, structural foundation assessment, counteract design, stability analysis with LEM method or in 3D Plaxis.
The recent years, our Company has competed more on the international marked. With competitive rates and high quality on deliveries, IKM Ocean Design are now working for Clients in Norway, Denmark, Russia, China, Canada and Australia, and we continue to expand our Client network.
