Jumping Jack was formally launched in 2002 with Mammoet, Van Oord and the Barris group owning a third each of the holding company.

Earlier this year the barge was sold to A2SEA A/S after Mammoet van Oord said that it "no longer saw added value in this unstable and politicially sensitve market. The Jumping Jack is an installation barge of a type known as a “jack-up”, specially designed to be used for offshore marine installations, foundations and topsides for wind turbines."
