... relative to the traditional steel-only M-shaped subsea jumpers. As such, the flow-induced vibration (FIV) threat from internal fluid flow must be assessed for the intended service. A three-tiered approach is used to assess the level of FIV threat expected in this TCP subsea jumper application. A high-level...

...Abstract Abstract A three-tiered approach is advocated to assess the level of flow-induced vibration (FIV) threat to process piping due to internal flow. The first-tier assessment is a high-level design check on the possibility of FIV. The tier-1 screening does not provide a framework...

... to existing structures which are aged but significant. One prime concern in such berths is the vibration that will be transmitted to the existing old structure during the construction of the new one. Therefore there is a requirement to keep vibration effects under control to ensure that existing structures...
