Block stowage and isolated stacks

RISQ 8D.8Section 8D · Cargo Operation: Cellular Container ShipsSource marking: V

Applicability: Section 8D applies only to cellular container ships. It must not be used for non-cellular ships carrying containers.

Isolated stacks and the coastal-ship exception are assessed.

Practice questions

Preparation prompts derived from this entry, not an official inspector interview script.

1Does every isolated stack necessarily require a No answer?

The source gives a Yes exception for coastal container ships where calculated lashing stress is within limits and the arrangement is recorded.

Where a finding may arise

Explicit RISQ trigger: isolated stacks, especially outboard. Preserve the stated coastal-container-ship exception when calculated lashing stress is within the allowable range and comments record the arrangement.

Past observations for practice

Source clarification

Stacks generally do not rely on each other for structural support; the source describes weather protection.
