Desk Equipment
Desk Equipment
(OP)
Are there any standards or literature for electronics mounted on ship's decks? I am working on something and I am concerned that it will get wet.
My first order assumption is that deck equipment will be submerged in water travelling at something in excess of the ship's speed. Does this sound reasonable?

When you add in the strong probability that someone will hit your electronics with an anchor or a chain, designing stuff for deck use is a case of belt and braces.

Also, if your item is particularly large, draws significant power from the vessel, air, hydraulics etc and is to be a permanent fixture then you may need to submit designs to the classification society for approval because it MAY affect the vessel class.
The rules do include information regarding greenwater on vessel decks.

It is a surveying device, and the ship probably will be fairly small. The device is battery operated, but it will be tempting to connect it to the ship's electrical power.
My primary concern is with waves crashing over the ship and damaging or tearing loose our equipment. NEMA 4 and IP66 both involve spraying with big hoses, and IP68 is submergment in still water. We would need to keep the box attached and sealed. There would be a safety hazard with any cables that dangle after a failure.
Are people on ship religious about removing deck equipment and stowing it below? If they are, there is another possible solution.
We are quoting on a job, and I want some idea of how messy and complicated this going to get. I have an approach worked out, but sombody must have solved this. This is not a good job for trial and error.
I will look up your sources.
