Mermaid Sapphire is an offshore multipurpose vessel.[2] Built in 2009, the ship is used for mostly research and undersea work.
She is a purpose-built ABS Classed DP2 ROV and air diving support vessel, designed for operation of dual deepwater work-class ROV's (Quasar Compact or Triton XLX) plus optional inspection-class ROV. The ROV's are installed on a dedicated raised deck level, leaving all back deck space for project equipment. Mermaid Sapphire is also equipped with state-of-the-art subsea inspection data acquisition and data management systems. A 23-tonne knuckleboom crane, and auxiliary 5-tonne crane are also installed.[1]
On March 26, 2012, she carried Deepsea Challenger to the Challenger Deep where the first solo dive to the bottom of the trench was made.[3]
