To mitigate the high-decibel noise generated during LNG carrier operations, Firsquare supplies dedicated exhaust silencers (DN50-DN150) specifically engineered for harsh cryogenic, corrosive, and explosion-proof marine environments. Integrating advanced acoustic technology and low-temperature resistant designs, these silencers efficiently attenuate noise from natural gas, BOG, and nitrogen emissions down to industry standards. While adapting to limited shipboard spaces and ensuring unobstructed exhaust flow, they provide a highly reliable, compliant, and low-noise acoustic solution for the safe operation of LNG carriers.

The Olive Vent Cowl for LNG Vessels is a critical ventilation and protection device installed on exposed decks, cargo tanks and vent systems of ships. It is mainly used together with vent silencers, relief lines and pressure-vacuum valves. While ensuring normal ventilation and air exchange for compartments and pipelines, it effectively prevents intrusion of rain, wind, seawater, insects and foreign matters. With excellent salt-spray resistance, low-temperature toughness and robust structure, it fully meets marine standards and the strict requirements of LNG carriers for cryogenic, explosion-proof and high-corrosion protection service.
