TRACK RECORD of TESTING, DEMONSTRATIONS and APPLICATION PROOFING.
- Initial proof on concept and geometry tests in Solent Towing Tank – UK
- Extended and confirmatory tests on geometry at various diameters and current velocities. Findings and results consistent with proof of concept tests. IFREMER flume Boulogne , France.
- Series of research tests demonstrating negative lift coefficient and cylinders in tandem. IFREMER flume , Boulogne , France.
- Demonstration at full scale on 21inch slick (bare) riser. MARINTEK , tow tank , Trondheim , Norway. Results show consistency at over 95% ASR ( Amplitude Suppression Ratio).
- Demonstration of VT on a complex arrangement of different diameter cylinders, Full scale stiffened wireline lubricator for use by Shell International on a sensitive investigation project. Solent Towing tank – UK
- Demonstration of an application for catenary risers and mooring lines. IFREMER, Boulogne, France
- Direct comparison of amplitudes of catenary risers and mooring lines with and without VT fitted. Results consistently recorded 95% ASR. IFREMER flume, Boulogne, France.
- Test programme to demonstrate capability of VT to contain and completely suppress FIV of a group of loose umbilical and control hoses in a strong current. Solent Towing Tank, Southampton UK.All the above have been recorded, logged and videoed and can be found in the video section of the site.
- Full scale ‘dry’ demonstration of VT deployment and recovery from a 7 inch completion riser, and a 16m tall scaffolding tower. Fleetwood UK.
- Full-scale deployment and recovery of VTs from a 7inch completion riser and from a group of umbilical and control hoses using techniques perfected in 9 above. Warren Joe Douglas Jack-up rig, Trinidad.
