TMT SST/FSB 18 3/4″ Override Tool

The TMT SST/FSB 18 3/4″ Override Tool was originally designed to open 18 3/4″ subsea trees at the connection between subsea tree and flow base, and the connection between flow base and wellhead.



Easy to install and remove

Corrosion resistant materials

Compact design


ROV deployed

This is achieved by placing the tool underneath the override rods found at the connectors and energising the tool hydraulics. The tool is lightweight, as high tensile Aluminium Alloy is used as structural elements.

Two tools are to be used at the same time. Each tool has two telescopic cylinders and is capable of exerting 125T.

An interface plate is provided to allow the tool to be used on both Subsea Tree (SST) and Flow Support Base (FSB) override rods.


TMT can customise the tool to suit your requirements.
