About us
With a staff of 2150, SINTEF is one of the largest independent research organisations in Europe. SINTEF performs contract research for private enterprises and public bodies within the fields of technology, natural science, medicine and social science.

SINTEF Pipeline Technology

SINTEF Pipeline Technology is a cross-discipline arena coordinating all SINTEF's R&D activities within pipelines and flow assurance, in close cooperation with the Norwegian University of Science and Technology (NTNU). The core group is formed by division of Flow Technology at SINTEF Petroleum Research, divisions of Structural Engineering at MARINTEK and division of Applied mechanics and corrosion at SINTEF Materials and Chemistry.

SINTEF Petroleum Research

SINTEF Petroleum Research concentrates on technologies for the identification and extraction of petroleum resources, both nationally and internationally. We develop solutions for exploration, field development and production. Our knowhow and technology support the creation of value in one of Norway's most important branches of industry.

Our research enables cost effective and safe transportation of unprocessed production fluids in wells and long distance flowlines. R&D areas cover multiphase flow and cold flow technology including hydrates, scale formation and solids transportation.

Division of Flow Technology operates the SINTEF Multi-phase Flow laboratory, the world's largest multi-phase flow laboratory. More than 10 000 tests have been performed during its existence, establishing crucial reference data for the development of multi-phase flow simulators. SINTEF has in cooperation with Institute of Energy Research (IFE) lead the development of the commercial multi-phase flow simulator OLGA 2000, sponsored by STATOIL, Conoco, Mobil, Total and Texaco. In cooperation with BP, SINTEF is developing a novel and patented, innovative process for transportation of oil, gas and water that simplifies installation, operation and maintenance significantly. In cooperation with ConocoPhillips and Total, SINTEF is developing the next generation technology platform for multi-phase flow assurance analyses of export lines and sub-sea processes through the multi-dimensional multi-phase flow simulator LEDA.

SINTEF Materials and Chemistry

The institute has high competence within materials technology, applied chemistry and applied biology. Closely with industry we develop advanced materials, products, processes and new tools. New, environmentally friendly processing methods increase productivity and raise quality standards.

Department of Applied Mechanics and Corrosion focuses on development, characterisation and reliable use of materials under demanding conditions and has for a long time carried out materials research and advanced consulting related to oil and gas pipelines. We have contributed to the development of hyperbaric welding technologies, development of low-alloyed steels with good welding properties, fracture and fatigue resistance and have made significant contributions to the use of new types of stainless steels, titanium and composites, as well as high-strength steels and corrosion resistant alloys especially designed for offshore pipelines. This has helped build the competence and understanding needed to understand the materials-related challenges of the industry.

We are developing new technologies and methodologies for ensuring fracture integrity of pipelines for strain-based design and for understanding degradation mechanisms altering component/structure integrity over life-time (fatigue, corrosion-fatigue, hydrogen embrittlement, stress-corrosion, high-temperature corrosion, erosion) etc.

The LINKpipe software tool for fracture mechanics assessment in pipelines is an example of a new technology that has been developed by SINTEF and NTNU
Our most important customers are; material producers, oil and gas operating companies and fabricators/service companies.


- the Norwegian Marine Technology Research Institute - does research, development and technical consulting in the maritime sector for industry and the public sector. The Institute develops and verifies technological solutions for the shipping and maritime equipment industries and for offshore petroleum production.

The division of Structural Engineering has specialised in development of advanced methods and computational tools for structural analysis, design and operation of marine structures. A unique combination of theoretical know- ledge, extensive laboratory facilities and engineering experience is our basis. Work is carried out in close cooperation with NTNU Faculty of Engineering Science and Technology, Div. of Marine Structures.

SINTEF Structural Engineering was established in 1971 to perform contract research within application of the Finite Element Method (FEM) for load-carrying structures. The division became part of MARINTEK in 1999. The division's activities are based on a combination of theoretical expertise, laboratory testing and engineering knowledge. This has formed a unique basis for development of numerical methods and tools for analysis of load-carrying structures and components. Since its establishment the division has developed a significant suite of commercial tools used by the international offshore and maritime industry. The division has also been an active contributor to the development of Norwegian and international standards for the offshore industry. MARINTEK Structural Engineering has been a central technology provider for Norsk Hydro's Ormen Lange project, developing specialised software (SIMLA) for analysis and design of pipelines in rough seabeds, considering free spans, stability, installation and optimal routing. This software is now installed as decision support tools on pipeline installation vessels.
