Yes.

Smaller company and down to earth attitude.

It's less safe than an office that's for sure. But the biggest accident in the company of 100 people has been due to arc flash and not due to walking across the shipyard. In general, the older colleagues seem physically as healthy if not healthier than average for their age; some having worked there for more than 20 years. I'm also surprised by this. The shipyard looks very dangerous but somehow not much happens to the electricians it seems from what I hear and see in the older colleagues.
