Overcoming the Challenge

Open

Stoppage of boil off gas

from LNG ships

Interim Operation

Identification, assessment and

elimination of all potential

sources of moisture

Root Cause Analysis

Deliberate and controlled tests to

determine effect of boil off gas

from LNG ships

Live Trials

Visual check and sampling of

critical equipment during

shutdown

Inspection

Deliberate and steady adjustment

of control parameters

Improved Control

Complement the facility with

external facility and process
