Lock Out Tool (LOT)
The TMT Lock Out Tool (LOT) is a mechanical locking device that is used to prevent subsea valves from closing after they've been opened and provides a mechanical means of locking the valve in a stroked position for a prolonged time. The tool consists of a splined rod that is actuated by the Linear Actuated Override Tool (sold separately) and an ROV operated locking handle.
The LOT has interchangeable components to enable interfacing with ISO 13628-8 Type A, Type B and Aker interfaces.
The LAOT can be engaged and disengaged from the LOT at any time by rotating the LAOT equipped with an ISO 1328-8 Type A linear interface (1/8 turn lock).
TMT can customise the tool to suit your requirements.
