3 Facilities Seawater laboratory H 2 S Laboratory Electrochemistry laboratory Wear and tribology laboratory Protecting coating: Paint and coating laboratory Autoclaves certified for 300 bars and 200 C Other activities Access to first class workshop services Access to advanced surface characterization (SEM, EDS, AES, ESCA, TOFSIMS GDOES) Closely integrated with NTNU, professors, students etc. 3

4 Seawater laboratory High Temperature Cathodic Disbonding Testing Long-term cathodic protection in real seawater directly from the Atlantic ocean 4

5 H2S Laboratory 4PB Stress corrosion cracking (SCC) HT/HP autoclaves Slow strain rate (SSRT) Four point bend (4PB) Constant load (CL) H2S laboratory SSRT Base material 13% Cr Method development Multi scale modelling Weld qualification Duplex weld 5

6 Electrochemistry Laboratory Electrochemical corrosion studies Electrochemical impedance spectroscopy Rotating electrodes Scanning Kelvin probe Corrosion in amine CO 2 capture process Corrosion in offshore power transmission Corrosion in process industry Material selection 6

7 Wear and tribology laboratory Environmental pin on disc Infinite focus image analysis Erosion up to 100 m/s flow rate Thermal spray of hard coatings Wear in hydraulic piston rods Cutting of silicon wafers Modeling of tribo-corrosion Wear in orthopedic implants 7

8 Corrosion protection with coatings Cost effective and durable coatings for offshore wind farms Paint TSZ Maintenance free coatings for long-life constructions Decreasing pressure drop in multiphase pipelines with coatings Plain steel pipe Corroded pipe Painted pipe Steel Horns Rev offshore wind farm, 2004: Premature coating failure after 2 year exposure Ormen lange 8

9 Erosion-corrosion Six cylindrical samples are fixed to a rotating disk. The disk rotates in a selected electrolyte together with silica sand. Geothermal Oil and Gas Data analysis includes a cumulative mass loss vs time, which gives information about the incubation time and the erosion rate. 9
