Modular, Stackable Wellhead System
A modular wellhead built from stackable sections rather than a single fixed assembly, so the configuration can be adapted to conditions found in the field — including damaged-well recovery and diver-assisted work.

When the well does not match the equipment, change the equipment.

The Problem
A conventional wellhead is essentially one fixed configuration. When a well is damaged, or when the work has to be done by divers in conditions nobody planned for, a fixed assembly forces the crew to adapt to the equipment instead of the other way around.
How It Works
- 01
The wellhead is built from discrete modules that stack, so height and configuration are assembled to suit the well rather than fixed at the factory.
- 02
Sections interface with each other through a common connection scheme, which is what makes the stack reconfigurable in the field.
- 03
The architecture supports recovery scenarios where the existing wellhead is damaged and a conventional replacement cannot simply be landed.
Why It Matters
- Adapts to what the crew actually finds, rather than requiring the well to match the equipment
- Directly supports damaged-well recovery and diver-assisted operations
- Manufactured in-house from the same shop that designed it
