Subsea Wellhead & Tubing Hanger Systems
This course covers subsea wellhead and tubing hanger systems. Participants study wellhead housings and casing hangers, seal assemblies and lock-down, load capacity and fatigue, running tools and installation, tubing hanger systems and orientation, control line penetrators, testing and verification, integrity monitoring and intervention on subsea wellheads.
Description
A subsea wellhead carries every casing string, seals each annulus, supports the blowout preventer stack and later the Christmas tree, and must do all of it on the seabed for the life of the well. It is a barrier element, a structural member and the interface between the well and everything above it.
This course covers the system in detail. It starts with wellhead housings, casing hangers and the installation sequence as each string is run, then covers seal assemblies, lock-down mechanisms and the sealing technologies used. It covers load capacity, bending and fatigue from riser and BOP loads, and the analysis behind wellhead fatigue life. It then covers running tools and installation operations, tubing hanger systems including orientation, control line penetrators and downhole line connections, and the testing and verification of each seal. The course closes with integrity monitoring of subsea wellheads, common problems and failures, and intervention and repair options when something goes wrong on the seabed.
Wellhead fatigue has become a central concern in deepwater operations. The riser and blowout preventer stack apply bending loads at the wellhead through vessel motion and current, concentrated at the conductor and the high pressure housing. Over long drilling campaigns these loads accumulate damage at a rate that has to be tracked, because a fatigued wellhead cannot be replaced.
Seals are the other critical element. Each casing hanger seal isolates an annulus, and every one of them is installed blind at the seabed, tested by pressure and then expected to hold for decades. Installation practice, cleanliness, correct tool operation and verified testing are what make them reliable.
The tubing hanger adds orientation and control lines. It must land in a defined orientation so that control line and downhole gauge connections align, and the penetrators must seal and remain electrically and hydraulically sound. Problems here are expensive to fix because access requires a vessel and often a pulled tree.
By the end of this training, participants will be able to:
- Describe subsea wellhead housings and casing hangers and their installation sequence.
- Explain seal assembly types, setting and lock-down mechanisms.
- Assess wellhead load capacity, bending and fatigue.
- Apply wellhead fatigue analysis and tracking.
- Specify running tools and plan installation operations.
- Describe tubing hanger systems and orientation methods.
- Specify control line penetrators and downhole line connections.
- Plan testing and verification of wellhead and hanger seals.
- Monitor subsea wellhead integrity during drilling and production.
- Plan intervention and repair for wellhead and hanger problems.
The course is instructor-led. Equipment is covered with cutaway drawings, tool specifications and installation procedures, and fatigue with worked analysis examples. Field cases cover seal failures, orientation problems and wellhead fatigue issues and how they were managed. Participants are encouraged to bring their own equipment and problems for discussion.
Organisations sending participants to this training will:
- Improve subsea wellhead installation quality and seal reliability.
- Manage wellhead fatigue over long drilling campaigns.
- Reduce intervention caused by wellhead and hanger problems.
