Deltamarin contributes to record successes

Equinor’s Johan Sverdrup processing platform was transported from the yard in Korea to Norway by Boka Vanguard (formerly Dockwise Vanguard), the world’s largest semisubmersible heavy transport vessel, owned by Boskalis.

The unique open-bow vessel design was developed by Deltamarin in close cooperation with the owner and the scope of work included full concept design and classification design.

Since the delivery in 2013, Boka Vanguard has been transporting various heavy cargos around the globe, including a record-breaking load of a 90,000 tonne FPSO unit from China to Brazil.

Later this spring, the Johan Sverdrup processing platform was lifted in a single-lift operation on top of the jacket by the heavy-lift, decommissioning and pipe-laying vessel Pioneering Spirit (formerly Pieter Schelte), owned by Allseas. The installation of the 26,000 tonne processing platform set a new record as the heaviest single-lift ever executed offshore.

In August 2018, Pioneering Spirit broke a record in pipe-laying by installing a 32 inch pipe at a depth of 2,200 metres on a stretch of almost 6.3km in one day in the TurkStream project.

Pioneering Spirit has a lifting capacity of 48,000 tonnes and is designed for single-lift installation and the removal of large oil and gas platforms and for installation of large pipelines. The vessel is the largest construction vessel ever built and also holds the title of the largest vessel in terms of gross tonnage, breadth and displacement.
