Question 521General Subjects - Assistant Engineer

The correct answer is B. The brake on a horizontal electro-hydraulic anchor windlass is spring set and hydraulically released. This means that the brake is normally engaged by spring pressure, and it is only released when hydraulic pressure is applied. When the pump is brought to zero stroke or there is a loss of servo power hydraulic pressure, the brake will automatically set due to the spring action, stopping the windlass. The other options are incorrect because they describe the brake as being hydraulically set and spring released (A), or they state that the brake automatically releases when the pump is brought to zero stroke or there is a loss of servo power hydraulic pressure (C and D), which is the opposite of how the system is designed to function.
