LNG Cargo pumps

A typical LNG carrier features four to six tanks aligned along the vessel’s center-line. These tanks are surrounded by a combination of ballast tanks, cofferdams, and voids, creating a double-hull type design for added safety. For transferring LNG from the cargo tanks, each tank is equipped with two main cargo discharge pumps.

Pumps that handle LNG are specialized and specified for the unique requirements of these applications, which require operation under cryogenic conditions, submersion of the pump unit and very high reliability.

Highlights:

This course aims to equip seafarers with the necessary knowledge to understand the characteristics and components of LNG cargo pumps, their operation and performance curves, and the phenomenon of cavitation.

By the end of this course, you will be able to:

1. Identify the characteristics and components of cargo pumps.
2. Explain the operation of cargo pumps and interpret their performance curves.
3. Describe cavitation and its impact on cargo pump performance.
