The Pump Tower is a vertical structure installed within the cargo tanks of an LNG Carrier (LNGC), serving as a critical facility that plays a pivotal role during LNG loading and unloading operations.

It is engineered to maintain structural strength and safety even in cryogenic environments, supporting the stable operation of cargo transfer and fuel management systems.

As a key component of the LNG discharge system, the Pump Tower is vital to ensuring the safety and operational reliability of the vessel.

The Liquid Dome Cover is a critical structural component that supports and secures the Pump Tower from the top within the cargo tank of an LNG carrier.

It is positioned above the coaming installed at the trunk deck penetration and serves as the upper fixing point for the Pump Tower, maintaining its vertical alignment and ensuring structural stability.

The Liquid Dome Coaming is a fixed foundation structure that supports the Liquid Dome Cover and serves as a key element in maintaining the structural stability of the cargo tank's upper section.

It is installed as an integral part of the Trunk Deck, ensuring the continuity of the insulation structure while securely supporting both the Dome Cover and the Pump Tower.

The Gas Dome is a structure installed on the top of an LNG carrier's cargo tank, serving as an outlet to safely transfer Boil-Off Gas (BOG) generated inside the tank to external systems.

It is directly integrated with the tank, and the generated BOG is routed through connected piping and valves to fuel supply, reliquefaction, or venting systems.

The Vent Mast is a vertical gas discharge structure installed on the upper deck of an LNG carrier and designed to safely release BOG (Boil-Off Gas) generated during operations or excess pressurized gas in emergency situations into the atmosphere.

It is connected to the final venting point of the gas handling system, serving to direct gas safely to the atmosphere when the normal processing route is unavailable.

The Manifold is a platform designed for the loading and unloading of LNG. Located on the outboard side of the trunk deck, it serves as the gateway for LNG transfer and acts as the connection point for loading arms from onshore terminals or FSRUs.

Furthermore, it is integrated with the Emergency Shutdown (ESD) system and its related instrumentation; in the event of an abnormal situation, it plays a critical role in ensuring the safety of both the vessel and personnel by swiftly cutting off the flow of LNG.
