24. When the derrick is secured for sea the head will rest on the
- A. Mast house
- B. Crutch stand
- C. Hatch cover
- D. Deck
Answer: B — Crutch stand
When a derrick is secured for sea, its boom (head) rests on a crutch stand, which is a secure support designed to prevent movement and stress on the mast or deck.
25. Eccentric rollers are lifted on steel hatch covers
- A. Grease the eccentric rollers
- B. To make the hatch cover roll on the trackway
- C. When the hatch cover has to be repaired
- D. To batten down the hatch cover
Answer: B — To make the hatch cover roll on the trackway
Eccentric rollers are part of the mechanism that allows steel hatch covers to be opened and closed. Lifting or rotating them disengages the cover from its locking position, enabling it to roll smoothly on its trackway.
26. Ship sweat occurs when a vessel loads cargo in a
- A. Cold place to another cold place
- B. Cold and wet place and goes to a warm place
- C. Warm place to another warm place
- D. Warm and humid place and goes to a cooler place
Answer: D — Warm and humid place and goes to a cooler place
Ship sweat occurs when warm, moist air inside a cargo hold comes into contact with a colder surface (like the ship's structure or cargo). This temperature difference causes condensation to form, potentially damaging cargo.
27. Before entering enclosed spaces, the space must be
- A. Filled with inert gas
- B. Cleaned
- C. Painted
- D. Ventilated
Answer: D — Ventilated
Before entering any enclosed space, thorough ventilation is crucial. This process removes or dilutes any hazardous or flammable gases and replenishes oxygen levels to ensure a safe atmosphere.
