In 2019 the vessel was chartered by Carnival Cruise Lines at short notice to facilitate repairs to Carnival Vista’s azipod system. This occurred at a time when the facilities at Grand Bahama Shipyard were unavailable. She was also lined up at one point to carrying the Costa Concordia following that vessel’s salvage off the coast of Italy, however the vessel was ultimately towed, supported by massive buoyancy chambers to the port of Genoa for breaking.

Established in 1910 to specialize in dredging and coastal defence and land reclamation, Royal Boskalis Westminster N.V. acquired compatriot Dutch shipowner Dockwise in 2013 and in 2018 the brands were merged under the Boskalis name. In March this year, the largest shareholder of Boskalis, an investment company named HAL Holding (whose history lies with Holland America Line) announced a takeover of Boskalis with an all cash offer €4.2 billion (approximately $4.6 billion) to take the company from publicly listed to private. The transaction has subsequently been finalized.
