Nikkiso Cryogenic Industries’ Clean Energy & Industrial Gases group (Nikkiso Cryo), a subsidiary of Nikkiso Co. Ltd (Japan), is the primary pump supplier for Excelerate Energy’s floating storage and regasification unit (FSRU) Experience.
The FSRU Experience recently reached a send-out capacity of 1.06 billion ft3 of natural gas. Nikkiso Cryo’s suction vessel mounted vertical submerged motor centrifugal pumps were used on the FSRU.
The product is designed so that the pump and suction vessel become an integral part of the piping system with external suction and discharge connections. The pump is mounted to the top (or head plate) of the vessel such that the pump, motor and fluid product are completely contained within the pressure vessel.
The suction vessel also serves to allow entrained vapours to be separated and travel through the vent line of the vessel and not into the pump. Removal of the pump requires only that the suction and discharge valves be closed with subsequent purging of the suction vessel. A key benefit of this pump is that shaft seals are eliminated. Having the pump inlet below the suction vessel inlet allows the source tank liquid levels to be lowered to a minimum, which allows for more product to be pumped out of the ship.
Peter Wagner, CEO of Cryogenic Industries and President of Nikkiso Cryo said that the group's achievement of reaching a send out capacity of 1.06 billion ft3 of natural gas "demonstrates the value of FSRU’s to provide cost effective clean energy solutions globally”.
