Marine Growth Cover
Marine Growth Cover
The TMT Marine Growth Cover (MGC) Class 1 - 4 are an economical way of protecting subsea XT rotary intervention valve buckets to standard ISO 13628-8 high torque receptacles, from excessive marine growth build up.
The non-metalic plug is fitted with a Nitrile Ring for retention. The TMT MGC isolates the valve bucket from the marine environment. The physical presence of the plug inhibits the buildup 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.
TMT can customise the tool to suit your requirements. All TMT MGCs are designed to last over 40 years in the subsea environment.
