Wärtsilä Svanehøj  long shafted deepwell pumps have proven their reliability for years onboard gas carriers, tankers and FPSOs. Wärtsilä has continuously improved and optimised its concept for deepwell pumps to develop pumping solutions capable of excelling in the highly demanding regulatory and operational offshore environment.


After 20 months of operation, the Offshore Installation Manager on the Yùum K’ak’ Náab, reported, acceptable vibration levels, no noise, and no downtime due to pump or electrical motor.

In April 2014, after more than 16,000 hours in operations, one of the pumps were taken out for overhaul and inspection. The BWO superintendent concluded that the shaft guide bearings were in very good condition without any measurable wear. As a result, there was no reason to plan any similar maintenance on the other pump units.

In March 2016 Yuum K'akNàab passed 2000 offloadings, adding up to 1.24 billion bbls offloaded in total.
