Emergency Relief Hatch
A safety device that releases internal pressure to the outside by opening the cover by rupturing the Tension Rod of the Emergency Relief Hatch
when the pressure between the cargo hold space and the bulwark exceeds the design pressure due to a gas leak from a storage tank on an LPG ship
Excellent sealing performance, no leakage
Built-in diaphragm for sealing
Mainly applied to LPG carriers, land tanks, etc.
High reliability for setting pressure by using a specially designed tension rod
Low pressure setting possible
Low maintenance costs since resetting is possible only by replacing some parts after a rupture
