What is the minimum area under the GZ curve from 30 to 40 degrees that is required for container ships greater than 100 meters?

For container ships greater than 100 meters in length, regulatory stability criteria are in place to ensure safety at sea, particularly regarding the capability to resist capsizing. One such criterion involves calculating the area under the GZ curve, which represents the righting lever of the vessel at various angles of heel.

The area under the GZ curve from 30 to 40 degrees provides an indication of the vessel's stability. The minimum requirement for this area is set by safety regulations, which specify that it should not be less than a certain value. For vessels of this length, the standard requirement is typically set to ensure sufficient stability and prevent excessive heel that could lead to dangerous conditions.

The correct answer reflects the established safety standards for this particular category of vessel, indicating that having a minimum area of 0.006/C m.radians under the GZ curve between 30 and 40 degrees meets regulatory requirements. This ensures that the ship has a sufficient righting moment to recover from a lean, thus minimizing the likelihood of capsizing.

The other options present higher values than what is required by the standards, which might apply to different categories of vessels or specific conditions, but for container ships greater than 100 meters, the minimum specified is 0.006
