... component in a deepsea mining system is the production riser used to transport the production stream, usually in the form of multi-phase slurry, from the seabed level to a production vessel at the surface. For this reason, the riser is also known as VTS (Vertical Transport System). Unlike a normal...

... depths between 1300 and 2200m in the Gulf of Mexico. The riser is designed to interface with a semi submersible production vessel but may also be used with an FPSO with minor modifications. The design approach minimisis the riser steel weight and buoyancy requirements and achieves an optimum dynamic...

.... The Norne production ship will be the largest monohull production vessel in the world with an oil production capacity of 27,500 Smb/d (172,956 bbl/d). From the swivel on the turret the well stream is transferred to the inlet separator which will be operated at 15-20 bar. Oil from the inlet separator...

... way to layout an offshore production and drilling facility. ~ drilling wellhead platfrom (VFA) is connected to a floating production vessel (VFB), which is a converted drilling rig. This paper presents the general philosophy for developing the concept, split of systems between the platforms...

... ABSTRACT This paper summarizes the main conclusions of a 1987 study of semisubmersible Floating Production Vessel (FPV) capital costs. The study was based on an actual FPV case (Balmoral) and a comparison with a drilling rig (Vinni) built concurrently at the GVA yard. The FPV?S higher cost...
