Just be aware that you're likely encountering a real hazmat situation and want to be properly protected. Being the one who sold a lot of hazmat equipment to the Naval dismantlers of the mothball fleet in San Pablo Bay, as well as having seen the health of friends who once worked at the Mare Islands shipyards catastrophically fail early on, I can only presume hazards would be even worse in India, Compliance measures or not. Sounds like Cancer Alley. Expect a lot of loose lead, cadmium, and hazardous chromium compounds around. If you're from SF, you must be aware of the stupendous cost which has been undertaken to make the old Hunter's Point shipyard and shoreline area even somewhat safe to the public again. But yes, the photographic opportunity would be tempting.
