Solent just of the Isle of Wight

We had to remove oil and water from a sump in a tunnel which was 42ft below the sea inside a big concrete chamber accessed from a manhole. This is located in the Solent just off the Isle of Wight. It housed a generator and pump equipment for Wight Link ferry’s. The photos below show us accessing by winch as it’s classed as confined space you can also see the gas detector just in case there are gases present.
