Figure out the weight of the device (ROV, submarine,etc), and then the weight of the water displaced. When they are equal, the device is neutrally buoyant. However, usually engineers create a ROV with a slightly positive or negative bouyancy, personally I perfer a positivly buoyant ROV because if you lose power or the tether is cut the ROV will ascend back up to the top.
A more simple answer is that when the gravity & buoyancy are equal it is neutrally buoyant

Why does a rock has to sink?
A rock sinks because it is not buoyant. Buoyancy is whether or not something floats in water. There are three levels of buoyancy; buoyant, neutrally buoyant, and not buoyant. When something is buoyant, that means it has a lower density than water, causing it to float. When something is neutrally buoyant, that means it has roughly the same density as water, causing it to float half way between the bottom and the surface. Finally, when something is not buoyant (like a rock), that means that it has a higher density than water, causing it to sink to the bottom.
What is an object that won't float or sink in water?
neutrally buoyant
What effect does buoyancy have on items?
the effect that buoyancy has on items is floating, if the particular item floats it is positively buoyant, if it sinks it is negatively buoyant, if it neither floats or sinks it is neutrally buoyant. hope this helps!!
How do submarines stay in the water without sinking or submerging?
they are neutrally buoyant. they have ballast tanks to achieve this
Is an object neutrally buoyant when it displaces an amount of water less than its own weight?
No, it sinks
Does the swim blather of a fish generally keep the fish positively neutrally or negatively buoyant?
no that never happens Yes.
What has the author Willard Dow written?
Willard Dow has written: 'A neutrally buoyant suspension system for underwater instruments'
Explain the advantages of being neutrally buoyant when you are a scuba diver.?
You do not float to the surface nor do you sink- you stay at the level you swim to.
What volume of air in a lifting bag will hold a mooring with a volume of 20 liters and a mass of 100kg neutrally buoyant in freshwater?
100ltrs
What object floats in the middle of water?
what object will not sink or float but will stay suspended in the middle of water
What does neutrally buoyant mean?
Something that neither floats nor sinks, stay in the middle of the tank or water subject it's in. Exp: bamboo with a balloon neither floats nor sinks in the tank. It stays in the middle on the 4 gallon tank.
How does the buoyant force affect a submerged object?
If the weight of the object is higher than the buoyant force the object SINKS. And the opposite happens if the weight is lower than the buoyant force. If it is equal, the object neither sink nor float, it is neutrally buoyant.
