Question 3296 Deck General

The correct answer is B) slip joint. The slip joint in a marine riser system compensates for the up-and-down motion, or heave, of a floating platform or vessel. The slip joint allows the riser to move vertically to absorb the heave of the floater, preventing excessive strain on the riser. The other options are incorrect because: A) A flex joint is used to accommodate angular deflection, not heave. C) The riser joint is a generic term for any connection in the riser system. D) There is no specific "heave joint" - the slip joint is the component that compensates for heave.
