Abstract
A through the flowline or "TFL" tool selector has a base provided with a number of spaced flowline ports and a diverter tube shiftably mounted in a housing for selective communication with the flowline ports. The base is mounted on a remotely operable connector, and the assembly is lowered onto a template beneath the sea having conduits aligned with the selector ports when the assembly is connected to the template. The inlet conduit loop of the selector assembly is also connected to an inlet conduit on the template. The connector is remotely operated to mechanically lock the selector apparatus in place.
