Mate, your already in the dream world…
ROV work (unless your a favoured son) IS seasonal, assuming you remain in the same region. It is a global industry.
Assuming that you can travel internationally there are are no seasonal limitations. This enables you to go and under-cut the wages of someone somewhere else.:(
Salvage – I’ve never worked personally but from encounters with people who have; be independently wealthy and an adventurer i.e. not scared of bombs, bullets, bullshit and various other hazards. In other words quite often a high risk investment of your time and effort.
Please conduct an audit of all your bits and decide which ones you want to keep.
Good luck,
