DNV GL to Test Bolt Fatigue for API

controlled environment within DNV GL’s global laboratory network involving its sites in Columbus, Ohio and Norway, which provide extensive corrosion expertise and the ability to test up to capacities of 7,500 kN. These laboratories have key subject matter experts in the areas of fatigue of subsea equipment, bolting connections, cathodic protection and instrumented tests. The tests will be highly instrumented to record the number of cycles, stresses, strains, current, pH and oxygen level.After testing is completed by late 2019, the data will be shared on DNV GL’s digital platform Veracity

C-Kore Systems Rolls-out New In-line Testing Tools

Monitor tests the health of electrical lines by measuring the insulation resistance and continuity. The Subsea TDR identifies faults along electrical lines with a precision of 10cm.Greg Smith, General Manager for C-Kore Systems commented: “Many of our customers have access issues with their subsea equipment. There just isn’t enough space. In the past we’ve resorted to extension whips but this introduces another variable in the measurements."Greg added: "With our new in-line units we can now plug directly into the equipment even when clearance is tight, ensuring accurate readings
