Description
Technical field
The present invention relates to the assay device of a kind of field of ocean engineering, it is more particularly related to one is examined
Consider the submarine pipeline vortex-induced vibration experimental provision across shoulder pipeclay effect.
Background technology
The deficientest with landing field petroleum resources, people concentrate on offshore and gas development more sight, then, and seabed
Pipeline becomes marine oil and gas and exploits the life line transported, and its quantity is also increasing year by year.
Owing to deep seafloor is with a varied topography, bad environments, submarine pipeline can inevitably form suspended span section.Sea water flows through
During suspended span pipeline, pipeline trailing edge can produce vortex shedding alternately, when vortex shedding frequency and the pipeline natural frequency of vibration are close, and pipe
The vibration in road will force vortex shedding frequency to be fixed near the pipeline natural frequency of vibration, thus " locking " phenomenon occurs.And pipeline
Vortex-induced vibration and " locking " phenomenon are to cause pipeline gas engineering, fatigue, the principal element even destroyed.Simultaneously as submarine pipeline
Coupling across shoulder pipeclay so that the mechanism of vortex-induced vibration and " locking " phenomenon becomes more complicated accordingly, it would be desirable to further
Research pipeclay effect is on the impact of submarine pipeline suspended span section vortex-induced vibration and mechanism thereof.
Lot of domestic and international scholar has carried out substantial amounts of research to submarine pipeline suspended span section vortex-induced vibration problem at present, such as moves
The MARINTEK research institution of prestige has carried out the vortex-induced vibration experiment of part multispan pipeline during 2000 to 2003 years, goes forward side by side
Specification DNV-RP-F105 (2006) that one step is perfect, 21 ocean, the boundary offshores held in 2002 and polar region engineering international conference
On article " VIV response of long free spanning pipelines " (long free suspended span pipeline vortex-induced vibration
