Global heavyweights in the offshore transportation and installation sector are competing for the first batch of processing platforms to be decommissioned by ExxonMobil in Australia’s Bass Strait.

ExxonMobil’s local subsidiary Esso Australia invited selected contractors earlier this month to each describe how they would undertake the removal of the first batch of offshore platforms, all of which are ageing, large steel structures.

The US operator has not disclosed the names of the contractors but market sources said they are Allseas, Heerema Marine Contractors, Saipem, Offshore Oil Engineering Company (COOEC) and Sapura Energy.
