Which of the following most accurately describes a disadvantage of High Tensile Steel used in ship structures? Select the ONE best answer

One correct answer

When corrosion occurs, the rate of loss of strength is more than for ordinary mild steel✓ Correct answer
It is more expensive
It is heavier than mild steel
It is more prone to corrosion

Which ONE of the following statements about hull inspections is most accurate?

One correct answer

Ship’s crew should regularly inspect the cargo holds, hatch covers and ballast tanks with a view to detecting damage and defects✓ Correct answer
Ship’s crew are not allowed to inspect the cargo holds, hatch covers and ballast tanks
There is no need to detect damage and defects between surveys
Ship’s crew have insufficient training to inspect the cargo holds, hatch covers and ballast tanks with a view to detecting damage and defects.

Which one of the following best describes why bulk carriers are more prone to corrosion than tankers or container ships? Select the ONE best answer.

One correct answer

Bulk carriers suffer much more mechanical damage to coatings due to grab damage and other impacts during loading and discharging✓ Correct answer
They spend more time in port
Tankers and container ships have higher technology coating systems applied to their cargo carrying spaces
Bulk carriers are built of lower grades of steel

With regard to shear forces acting on the hull, which ONE of the following statements is most accurate?

One correct answer

Shear force is created when there are two parallel, opposite forces, like gravity and buoyancy✓ Correct answer
Shear force is created when there are two parallel forces in the same direction, like gravity and buoyancy
Shear force refers to the horizontal force at the forward part of the vessel
Shear force refers to the horizontal force at the aft part of the vessel

With reference to looking for defects in the hull structure, which ONE of the following statements is most accurate?

One correct answer

Indentations in the side and floor plating of Bulk carriers from cargo work can lead to corrosion and cracking✓ Correct answer
Indentations in the side and floor plating of Bulk carriers from cargo work are usually of no great importance
Large hatch openings on container and bulk vessels do not form part of the structure and therefore do not need close inspection
Double bottom tanks are not usually subject to corrosion
