WÄRTSILÄ SVANEHØJ ECA FUEL PUMPMODEL EFP

Emission Controlled Areas (ECA’s) and the development of environment friendly LNG fuelled engines have driven demand for highly reliable fuel gas systems. Introducing a fuel pump safeguards a steady and reliable fuel gas supply with a fast response on engine load transients. A fuel pump is independent of weather conditions, sloshing and thermal conditions. The Wärtsilä Svanehøj ECA fuel pump (EFP) is a downsized version of our famous deepwell gas pumps.It offers the advantages of no tank connections below liquid level, no electrical components inside the tank and minimised contribution to boil off gas generation.

The Wärtsilä Svanehøj EFP is developed in close cooperation with designers of LNG fuel gas systems to meet the demand of highly efficient, environment friendly LNG fuelled engines. It is also prepared for other fuel types such as Ethane and Methanol.Main design criteria:• Safety&Reliability• 5yearserviceintervalsor25,000 operating hours• Contingency:safehandlingin emergencies.

PUMPING LIQUID GAS FOR 50 YEARS Wärtsilä Svanehøj deepwell cargo pumps have proven their reliability for more than 50 years at sea. Over 5000 pumps on 1000 gas carriers are handling LNG and LPG on a daily basis. Wärtsilä Svanehøj deepwell cargo pumps are renowned for stability, very limited downtime and long service intervals matching normal docking intervals. Every ship is handled as an individual project with a dedicated team of skilled engineers and craftsmen handling the pump systems - from first quotation to the installation, commissioning and testing. All the benefits of the existing large Wärtsilä Svanehøj deepwell cargo pumps have now been attributed to the more compact Wärtsilä Svanehøj ECA fuel pump.

DESIGNED FOR YOUR DEMANDSWärtsilä Svanehøj EFP pumps are designed for continuous operation by variable frequency drive. The product range is shown here, please refer to the datasheet and product guide on wartsila.com for further technical information.

5 YEAR SERVICE INTERVAL

Fuel pump control is directly related to the engine load. As the pump should deliver the right pressure/flow over the entire engine load range it will periodically operate at duty points where pump and motor have a low efficiency. If the electric motor is installed inside the fuel tank in some situations a low

ELECTRIC MOTOR: HEAT AND PRESSURE REDUCTION

The Wärtsilä Svanehøj EFP pump in normal circumstances only requires servicingevery5yearsduringregulardockings. However our “3 service area concept” enables access to motor, bearing and pump at any time even with gas pressure in the tank:• Service Area 1: Electric motor and magnetic drive can be serviced at any time.• Service Area 2: By activating a static seal, the system can be purged and axial bearings can be accessed. Main bearing and inner magdrive can be serviced.• Service Area 3: By activating the foot valve, the system can be purged and the pump can be retracted in handy sections of less than 1 metre. This provides unique service possibilities and ultimate peace of mind. Your fuel supply is also secured and can easily be restored in case of emergency.

The Wärtsilä Svanehøj EFP is based on well proven technology used on gas carriers for decades. We have designed a hermetically sealed pump without any sophisticated bearings or exotic materials, using standard ball bearings that ensure a long service lifetime. Service intervals are 25,000 operating hours or every 5 years.
