H2 generation in deep sea

H2 generation in deep sea

H2 generation in deep sea

(OP)
Hello,
As electrical engineer, I am in charge of looking for the potential risks related to the deep sea effects (laying depth > 2000m).
I have been made aware about potential problems related to H2 generation in power cables that could lead to early breakdowns at the connections. I do not exactly understand the concern and the mechanism of H2 generation.

Could anybody help me to better understand this phenomena, its related failure probability, and how to manage it efficiently? Is there any way/publication presenting a testing method for assessing it?

Thank you so much,
Foudretta  

RE: H2 generation in deep sea

Hydrogen can be created chemically as a result of seawater and electrical current.

The small airpockets that are created then expand with any heat or contract with cooling resulting in degraded lifespan of said elec. connector.

its a chemical process and combined with water pressure/heat causes premature failure.
