Stacking and retirement activity set to rise as oil price decline combines with oversupplied rig market

On the 15th January 2015, Transocean, Noble and Diamond Offshore all released copies of their new company fleet reports. Depressed activity within the offshore drilling space continues to force rig managers to assess their fleet capabilities in order to maintain their utilisation rates. The situation has been exacerbated by the declining oil price and as such forced managers to accelerate retirement and stacking plans, which is evident in the three reports released. Transocean, fresh from retiring 11 semisub units in December 2014 announced the retirement of the Discoverer Seven Seas drillship, whilst also indicating that the Transocean Rather semisub has now been put up for sale. Transocean also noted decreased dayrates for a number of its operational units as well as Statoil’s decision not to exercise an option to prolong the contract for the Transocean Spitsbergen which expires in July 2015. Whilst Transocean has been active in retiring a number of its older units, Noble and Diamond have both decided to cold stack units in January 2015. Noble announced the decision to stack both the Noble Paul Wolff and Noble Driller units, as Diamond chose to stack the Ocean Worker, which is currently enroute to the USA following the completion of its contract with Petrobras in Brazil. Retirement and stacking activity is expected to continue to rise throughout Q1 2015, as other rig managers also announce decisions about their older operational units
