Marine Growth Removal

TMT Marine Growth Cover – Class 5

The TMT Class 5 Marine Growth Cover (MGC) is an economical way of protecting subsea XT rotary intervention valve buckets to standard and ISO 13628-8 high torque receptacles, from excessive marine growth build up.


Easy to install and remove

Corrosion resistant material

Titanium bolts

Field proven

Standard receptacles include ISO 13628-8

The non-metallic plug is fitted with a nitrile ring to retain the MGC in the receptacle. The TMT MGC isolated the valve bucket from the marine environment.

The physical presence of the plug inhibits the build up of marine growth and helps to eliminate time consuming cleaning processes that could be required before a torque tool can re-enter the valve bucket. All TMT MGCs are designed to last over 40 years in the subsea environment.


TMT can customise the tool to suit your requirements.
