The demolition market is rather volatile and prices can vary considerably from week to week. There are many factors that can influence prices including location, type, build quality, engine serviceability, and domestic demand for scrap metal. It's certainly not unusual at the moment for scrappers to pay $350-400/ldt for a high-quality tanker and only $150-200/ldt for a 'dead ship' ferry on an 'as is' basis. A well-maintained, serviceable ferry, on the other hand, may command a higher price, should supply/demand factors be favourable.
Bangladesh has been the No.1 player for the best part of this year with prices for tankers (the preferred vessel type) hovering around the $400/ldt mark. This is very much a historical high, largely due to a dearth of tonnage available. India has been playing second fiddle and has not been able to compete with Bangladesh for much of the year and has turned to less conventional (as far as scrappers are concerned) vessels such as passenger ships, reefers and trawlers. These are of little interest to Bangladesh and therefore the 'big bucks' money tends to elude this segment of the market.
I have loads of statistics and price trend data available at work on this very subject. If you are really interested in this area, and it's only for your own personal interest, I can forward some data to you by email.
