Hyber - Riser Interference Assessment

Application:

Top tensioned risers on TLPs and deepwater platforms exposed to riser interference:

• Risk of interference
• Riser Clearance
• Riser Contact and damage

The technology is based on strip theory and pre-established interaction coefficients from lab tests and CFD computations. Databases for both smooth risers and risers with strakes.

Interaction over entire riser length

Capabilities:

• Fully 3D non linear time domain Finite Element simulations
• Arbitrary riser and umbilical configuration
• Floater motion
• Uniform or skewed current profile
• Fatigue and extreme distribution
• To be used on standard PCs
• Low user thershold
• Verified through laboratory tests

The technology has been developed and implemented by NDP (Norwegian Deepwater Programme) 1998-2004
