Reinforced Double Hull Construction

Barriers - the reinforced double hulls

Double hulls PNTL hulls are reinforced with 400 tonnes of additional steel to withstand collision damage.

The cargo compartments of the PNTL fleet are protected by a double hull configuration, extending to twenty per cent of the beam (width) on both sides of each ship. In addition, the hulls are reinforced with 400 tonnes of extra steel to withstand collision damage.

The reinforced double hulls of the PNTL ships are designed to withstand a 90-degree collision with a 24,000 tonne vessel traveling at 15 knots, without penetration of the inner hull. This means that the casks on board would not be directly impacted even in a severe collision at sea.
