ToolTec’s 3-Way Zero Leak Hotstabs (Mechanically Actuated stab system utilises a set of subsea rated wet-mate flat faced couplers, which when pushed together by the ROV, automatically connect and mechanically lock together. The stab will then remain mated and locked together, until the ROV physically pulls on the ROV handle, effecting the unlock and de-coupling of the hydraulic connections. This arrangement assures a near zero leak criteria, with less than 0.1mL ingress/discharge per line during each make/break operation.
