Q

The securing systems for containers were developed to prevent container movement during which ship motion?

🔍 Key Concepts

• Six degrees of freedom in ship motion: roll, pitch, yaw (rotations) and surge, sway, heave (translations) • How containers are stacked and lashed on deck and in holds • Which motion causes the largest side-to-side angle change at the container stack

💭 Think About

• Think about how a container stack actually moves relative to the ship when the sea is on the beam versus ahead or astern. • Ask yourself: which motion would most stress the vertical and diagonal lashings between containers in a stack? • Consider which motion changes the angle of the stack most, rather than just sliding it forward/back or sideways.

✅ Before You Answer

• Identify whether the motion in each option is rotational or translational. • Match each motion to its axis: longitudinal (bow-stern), transverse (side-to-side), or vertical. • Decide which motion would most likely cause containers to tip or lean, requiring strong securing systems to prevent toppling.
