TMT Marine Growth Cover - ISO Linear Type B

Marine Growth Cover
The TMT ISO Linear Type B Marine Growth Cover (MGC) is an economical way of protecting subsea Linear Type B receptacles from excessive marine growth build up.
The MGC fits over the ISO 13628-8 Linear Type B interface to protect both the front and rear faces of which subsea tools interface with. Polyurethane is used to retain the cover in position and stop it from rotating. The TMT MGC isolates the receptacle 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 using the receptacle.
TMT can customise the tool to suit your requirements. All TMT MGCs are designed to last over 40 years in the subsea environment.
