04 Mar 08. Work has begun to install new pyrolysis waste disposal equipment on HMS Ocean – a key part of the ship’s multi-million pound upgrade and maintenance programme being undertaken by Babcock Marine at Devonport. Strong progress is being made on the programme, which has seen the original work package increase in size with associated significant savings being identified. The pyrolysis equipment installation is one of the significant upgrades to HMS Ocean, and is the first use of the technology on a Royal Navy ship.
