Abstract

En dynamisk posisjonert flytende senkekasse særlig anvendbar for offshore-prøve- og utviklingsboring som innbefatter organer for reduksjon av den kraftmengde som er nødvendig for å holde senkekassen i posisjon. Senkekassen er selvstendig flytende ved oppdriftstanker. Et dekk og en borerigg er plassert på toppen av senkekassen. Senkekassen har en vertikal sentralt plassert brønn gjennom hvilken bore- og/eller produksjonsstigerør passerer. Senkekassen har en tverrsnittsform som er strømlinjeformet for å redusere den dynamiske kraftpåkjenningen forårsaket av havstrømmer og bølger.A dynamically positioned floating submersible box particularly useful for offshore test and development drilling including means for reducing the amount of force needed to hold the submersible in position. The sink is self-contained in buoyancy tanks. A tire and a drilling rig are located at the top of the sink. The lower box has a vertically centrally located well through which drilling and / or production riser passes. The submersible box has a cross-sectional shape that is streamlined to reduce the dynamic force exertion caused by ocean currents and waves.
