On offshore drilling units where natural ventilation is provided, each porthole or window must be fitted with _______________.

A curtains
B covers
C portlights
D screens
AI Explanation

The correct answer is D) screens. Offshore drilling units that rely on natural ventilation must have screens fitted on each porthole or window. This requirement is specified in the regulations governing marine safety and environmental protection for offshore drilling operations. Screens help to prevent the entry of insects, debris, and other foreign objects into the vessel's interior, ensuring a safe and controlled air flow through the natural ventilation system. The other options, such as curtains, covers, or portlights, do not fulfill this specific regulatory requirement for natural ventilation on offshore drilling units.
