The Paris Memorandum of Understanding on port state control (Paris MoU) is preparing to end the supply of inspection data to ship safety vetting agency RightShip, and the speculation is that the move is in response to criticism of the company’s new ratings system.

From next March, it is understood the Paris MoU is considering no longer supplying its port state control (PSC) data to market information company IHS Markit, which sells it on to a number of end users including Melbourne-based RightShip.
