A real survey-vessel design problem shows why machinery choice has to fit a ship's sensing mission. A large, noisy diesel could serve a fishery-protection vessel, but its acoustic interference stopped a survey vessel from locating fish effectively. Designers changed the propulsion arrangement on the second ship while it was still under construction. The completed first ship required difficult soundproofing, showing the cost of correcting machinery and sensor interference late.

Why engine noise defeated a fishery survey ship
A large diesel installation prevented a fishery survey vessel from detecting fish, forcing different solutions for two ships.
