Comparison of FGS System

Title

FGS system Reliquifaction capability Expected Application

1. Cryo pump Separate BOG handling required

All vessels except LNG Carrier

2. Cryo pump & reliq 100% LNG Carrier

3. Compressor Separate BOG handling required OR

LNG Carrier

15-25% of LNG flow to ME with basic partial reliq system possible OR

LNG Carrier

Up to 100% reliq possible with cascade or brayton cycle

•ME-GI can be applied with: 100% reliquefaction system, partial reliquefaction system, no reliquefaction system at all

• Selection of a reliquefaction system is typically dependent on vessel requirements with regards to:

Sailing profile Proportion of time with HFO or Gas operation Amount of BOG produced from cargo tanks Value of BOG and/or LNG

…and not a requirement of ME-GI

BOG handling on LNG Carrier with ME-GI


2. HP Pump Solution with 100% reliquefaction


3. High Pressure Compressorwithout reliquefaction


Combining LNG BOG and high pressure process compression technology

Optimal selection of compressor sealing system

Fully balanced, single casing, slow speed vertical frame design

Gas-tight compressor casing
