The MV Solo was a Greenpeace ship from 1990 to 1995, originally built in 1977 as an ocean tug called the Smit Houston.
Greenpeace updated the ship with a helipad as well as veterinary and laboratory facilities.
At this time the ship was renamed as the ETV Waker.
On 7 September 2009, a fire starting in the engine room so seriously damaged the vessel that she was scrapped.
