Millennium Offshore Services (MOS) completes purchase of jackup rig

Millennium Offshore Services (MOS) a provider of offshore jackup accommodation vessels globally has successfully completed the purchase of Transocean’s ‘Trident IV’ jackup rig which is to be renamed the ‘MOS Frontier’. MOS purchased the jackup rig for an all-in price of US$25 million and plan to turn the rig into an accommodation jackup vessel to target accommodation work in the Middle East, Asia-Pacific and North African regions. The ‘Trident IV’ jackup was put up for sale by Transocean in October 2012 and has been idle since completing a contract in Nigeria in 2008. The sale also falls in line with Transocean’s strategy to move the company further towards a purely high-specification asset rig operator.
