UWD-10 Slimbore

FMC Technologies' UWD-10 Slimbore Systems allow the use of reduced-diameter riser systems for drilling and production applications, are suitable for H2S service and are available in 16-3/4", 14-3/4" and 13-5/8" nominal-bore diameters. Each system has a rigidizing mechanism to provide enhanced fatigue resistance.

The UWD-10 Wellhead System is designed for a complete range of drilling and production scenarios in shallow or deep water with subsea or surface BOPs. This makes it possible for early-generation drilling vessels to drill in deeper water, and floating production facilities can increase the quantity of production risers tied back to the host platform.

Based on the industry-leading UWD-15 running tools design, the Slimbore continues the tradition of providing multi-function running and test tools. The tools provide the option of running and retrieving components either individually or in combination.

 System Description

 13-5/8" Slimbore

16-3/4" Slimbore 

Designed to accommodate vertical trees, allowing the tubing hanger to be installed in the wellhead and alleviating the requirement for a tubing head. The high-pressure wellhead housing has one passive and one active load shoulder for landing one casing hanger with a tubing hanger inside the housing.

Features a passive load shoulder in the high-pressure wellhead for landing and stacking the casing hangers. The integral rigid lock mechanism creates preload between the low-pressure and high-pressure wellhead housings. This preload provides improved fatigue life, allows for higher bending and torsional loads generated by TLP, Spar, DP drill ships and DP semisubmersible applications.

Features

  • 10K psi-rated wellhead
  • Wellhead casing weight and pressure load capacity is 3.1M when configured with one casing hanger and one tubing hanger
  • 27" OD H4 mandrel profile connection
  • Metal-to-metal annulus seal assemblies in the wellhead
  • Rigid Lock System rigidizes high-pressure housing to the 30" conductor housing with 1.0M lbs. preload
  • 10K psi-rated wellhead
  • 3.5M lbs. casing weight and pressure load capacity with passive load shoulders
  • 27" OD H4 mandrel profile connection
  • Metal-to-metal annulus seal assemblies in the wellhead
  • Integral Rigid Lock System rigidizes high-pressure housing to the 30" conductor housing with 1.5M lbs. preload

Ideal  Application

Wellbore of 13-5/8" that the tubing hanger will be installed in the wellhead Wellbore of 16-3/4" that can be used with a surface or subsea BOP
