A large amount of refrigerant gas was required to operate the 'porthole' system.
The introduction of more powerful diesel engines onto these vessels meant they had sufficient electrical capacity to supply the integral type containers.
Ducted containers had to be transhipped to their final destination after discharge and still required refrigeration for that part of the supply chain
The 'porthole' system design was extremely complex and construction costs were high.
Modern cellular container vessels which carry refrigerated cargo below deck mainly maintain an acceptable temperature in the cargo holds by which of the features given in the options?

Because cone-based lashing systems are more prone to failure than twistlocks
Because twistlocks provide uplift resistance as well as horizontal restraint, helping to prevent containers from falling overboard in heavy weather
