PROCESS AND SYSTEM FOR GUIDING DOWN AND SUBMERGING OF A PUMP AGGREGATE IN A TANK FLUID IN A TANK AND SUPPORT MEANS FOR THE AGGREGATE

摘要

A process and a system together with a support means for gas-tight and pressure-tight guiding down of a mobile pump aggregate (26) via a hatch opening (42a) in a tank (45), are based on the application that a sluice arrangement (12) is arranged gas-sealed and pressure-sealed outside the hatch opening (42a) with supporting abutment and sealing abutment via a seal (18) between the tank and the sluice arrangement, that the pump aggregate (26) is received in and surrounded by the sluice arrangement and is suspended in the sluice arrangement via an associated hoisting winch (23) internally in the sluice arrangement. The pressure between the tank (45) and the sluice arrangement (12, 63) is balanced and simultaneously an extra sealing pressure is established in the seal between the sluice arrangement and the tank. The hatch opening (42a) is uncovered in an open position and said pump aggregate is introduced by the hoisting winch (23) in the tank and is submerged in the tank fluid.
