2116780 9311416 PCTABS00022 A test apparatus (10) comprises an upwardly extending cylindrical housing (26) mounted on a skid (24). In use, a blow out preventer (BOP) (12) or other equipment to be pressure tested is lowered onto the upwardly extending cylindrical housing (26). [-shape guide rings (40) are positioned over the flange (22) on the BOP and a circular flange (34) on the upwardly extending cylindrical housing (26) using hydraulic piston and cylinder arrangements (48). Hydraulic fluid is admitted to a chamber (30) at the bottom of the upwardly extending cylindrical housing (26) to urge a piston (32) upwardly towards the flange (22) and form a sealed joint therewith via a gasket ring (44) which seats in aligned grooves in the top (66) of the piston (32) and the flange (22). Hydraulic fluid can then be admitted to the BOP (12) via hydraulic fluid supply line (70) to carry out the required pressure test.
