Marine Growth Removal

TMT Marine Growth Cover – Hot Stab

The TMT Male ISO Type B Hot Stab Marine Growth Cover (MGC) is an economical way of protecting subsea female ISO 13628-8 hot stab receptacles, from excessive marine growth build up.



Easy to install and remove

Corrosion resistant materials

Titanium rod

Field proven

Standard receptacles include ISO 13628-8

The non-metallic plug is fitted with O-rings for retention. The use of polyurethane provides compliance for the handle to allow for easy subsea installation.

The TMT MGC isolates the receptacle from the marine environment. The physical presence of the plug inhibits the build up of marine growth and helps to elminate time consuming cleaning processes that could be required before a hot stab can re-enter the valve receptacle.

All TMT MGCs are designed to last over 40 years in the subsea environment.


TMT can customise the tool to suit your requirements.
