Pioneering Spirit (formerly Pieter Schelte) is a split hull crane vessel owned by the Switzerland-based Allseas Group designed for the single-lift installation and removal of large oil and gas platforms, and pipelines. The 382-metre-long (1,253 ft), 124-metre-wide (407 ft) vessel is the world's largest vessel by gross tonnage, the heaviest vehicle ever made and since September 2021 also the largest floating sheerleg in the world. It was built in South Korea by Daewoo Shipbuilding & Marine Engineering (now Hanwha Ocean) in 2013 at a cost of €2.6 billion. It commenced offshore operations in August 2016.
