Enhanced Vertical Shelf Tree (EVST) by FMC Technologies Subsea Systems, FMC’s 5” x 2” 10K Enhanced Vertical Shelf Tree (EVST) system provides a cost effective and reliable solution for completing wells in shallow to moderate water depths of up to 2,500 feet. The EVST has an 18-3/4” Torus IV tree connector with a funnel down interface and an 18-3/4” H-4 profile top re-entry hub that mimics the tubing hanger/wellhead interface allowing BOP on tree interventions. The standard tubing hanger features a slim 12.18” OD, metal-to-metal seals, a 4-1/2” premium tubing thread connection and up to 4 downhole lines. ‘A’ annulus access is provided through a 1-1/2” gate valve in the tubing hanger, thereby eliminating the need for an annulus wireline plug. This allows the EVST system to be installed using a simple, low cost tubing string as the completion riser making it an ideal solution for simultaneously drilling and completing wells. The tree can be supplied with side flow (standard) or top flow (optional) flowline connections in diver assist or diverless configurations. The tree is operated by a direct hydraulic control system (standard) or an optional FMC MK IV mini-mux electro-hydraulic control system.
