Before I was injured at work I worked in the oil and gas industry for a long time.
It will be staggering just how much scrap equipment, tools and pipes have been left behind in our own waters.
One of the product lines was designed, and I'm sure it was a legal requirement, so parts could be removed from the sea bed.
For all the thousands of assembles sold to customers, only one tool for retrieval was ever ordered.
It's very clear that the companies drilling had zero intention of removing the tools and planned to leave them.
