Final answer:
The number of transversal frames on a ship like TSGB depends on the ship's design and size.
Step-by-step explanation:
The transversal frames are a concept used in civil engineering and shipbuilding to reinforce the structure of a ship. On the Torres Strait Grain Bunker (TSGB), the number of transversal frames would depend on the design and size of the ship. Without specific information about TSGB, it is not possible to determine the exact number of transversal frames on it.
