Wiring diagrams
(OP)
I am currently employed as a project engineer (mechanical) looking after a range of offshore cranes. I am increasingly asked to look at electric/electronic curcuit diagrams and have no idea how to really interpret what I am seeing. Can anyone recommend some good books or websites.

I suspect that the diagrams you are confronted with are more electrical than electronic in nature.
If that's true, then information written for electricians might help you more than that designed for engineers who engineer a system.
A used, 1st, 2nd or 3rd (1993) edition (now out-of-date) of "Industrial Motor Control" by Hermann & Alerich has a lot of information on motors and the control circuits for them, written to be understood by electricians.
There is a whole series of texts on specific electrical subjects published by Delmar, the Electrician's Technical Reference series. I have "Industrial Electronics" by Stephen Herman on my desk at the moment.
Delmar is at

I tend to look for used copies on half.com, ebay or abebooks.com, but you can decide how you want to acquire books.
If what you are looking at is Programmable Logic Control (PLC) circuitry, known as 'ladder logic', then the first couple chapters in a PLC text book would help. Frank D. Petruzella or John W. Webb are two PLC text authors (titles will include 'Programmable Logic Controller'). Someone's borrowed my copies so I can't quote a title for you.

I believe Siemens used to have a downloadable guide to reading DIN type schematics, but I'd need a couple of beers before attempting to navigate the Siemens website to see if I find it.
If you have contacts at ABB, Siemens, GE, etc, you might see if they have any guides that they can send you.
Good luck, and let us know if you find any good on-line resources.

Frankly, you need to push back NOW! Any fault in the electrical afterwards will be blamed on YOU, as will the liability. While you are probably protected by the industrial exemption, if your company gets sued, they'll dump you like a hot potato and try to find a job after that.
