Abstract
In one illustrative embodiment, the present invention is directed to a device adapted to be positioned adjacent an end of a tool housing of a subsea lubricator, wherein the device includes a structural member that is adapted to be positioned adjacent an end of the tool housing, a non-metallic body coupled to the structural member and a sealing device that is adapted to sealingly engage a wireline extending through the sealing device. The present invention is also directed to a method which includes lowering an assembly toward a tool housing of a subsea lubricator positioned subsea using a wireline for the tool to support a weight of the assembly, wherein the assembly includes a wireline tool and a device including a structural member that is adapted to be positioned adjacent the end of a tool housing, a non-metallic body coupled to the structural member, and a sealing device that is adapted to sealingly engage a wireline extending through the sealing device.
