    The unit features wireline valve (BOP) control and grease injection to BOP. Primary hydraulic power is provided by an electrically driven pressure compensating pump and backup accumulator capacity is provided to comply with all relevant requirements of Norsok D-002. Grease injection is provided by an hydraulically driven grease intensifier pump.

    Three modes of operation are provided, remote control from a control room, local control from a graphical interface on the unit and a fully manual operation panel. Grease injection can be automatic based on well pressure (patented NOV Elmar feature), automatic based on pre-set target pressure or fully manual. The system is configurable to work at either 15,000psi or 10,000psi well pressure.

    The unit is mounted within a weather proof container certified in accordance with DNV 2.7-1 and BS EN12079. All controls, reels and tanks are mounted inside the container behind secure lockable doors.

    Pipe fittings, tubing and fasteners are made from stainless steel.
