South Korea-based Hyundai Heavy Industries (HHI) has developed flame-retardant insulation for LPG cargo tanks in partnership with insulation system manufacturers.
The existing polyurethane foam, which acts as an insulation material for LPG cargo tank, is vulnerable to spreading fire.
The welding cut process at shipyards increases the probability of a fire outbreak, which can cause serious accidents and delays during the shipbuilding process.
HHI has established fire safety evaluation techniques and flame retardancy standards for the insulation material.
The company collaborated with manufacturers to develop an insulation spray system and a more flame resistant formulation of polyurethane.
The insulation material is now immune to a fire outbreak even after being exposed to fire sources.

It is capable of self-extinguishing within four minutes of catching fire, as well as reducing smoke emissions.
HHI CTO Shin Hyun-soo said: "During the 14-month development period, we came to a belief that the high flame-retarding insulation for LPG cargo tanks will play a key role not only in enhancing the safety of workers in the shipyards, but also in sharpening our competitiveness in winning LPG carrier orders."
Earlier this month, HHI unveiled its new 10,000th Hi-Touch marine and stationary engine (HIMSEN), which is currently incorporated in a 14,400teu containership ordered from Costamare, Greece.
