STRUCTURAL WORKS –
LPG & LNG VESSELS

HIDRAMAR GROUP
Structural Works in LNG and LPG: A Complex and Critical Process
LNG and LPG carriers are specialized vessels built to transport highly volatile and cryogenic gases. Shipyards constructing these vessels face unique challenges due to the stringent safety and structural integrity requirements.
At Hidramar Group, in order to succeed in the execution of these operations, there are some key structural considerations that must be accomplished:
– Cargo Tanks: These must withstand extreme temperatures and pressures. Common types include membrane, prismatic, and spherical tanks.
– Hull Structure: The hull must be robust to protect the cargo tanks and withstand the marine environment.
– Insulation: Effective insulation is crucial to maintain cryogenic temperatures.
– Fire Protection: Rigorous fire protection measures are essential due to the flammable nature of the cargo.
– Safety Systems: Redundant safety systems are incorporated to mitigate risks.
