SINGAPORE -- Sembcorp Marine has delivered what it claims is the world’s largest jackup drilling rig to Noble Corp. It will drill wells on Statoil’s Mariner heavy oil development in the UK’s East Shetland basin under a four-year charter agreement.
Noble Lloyd Noble is a harsh environment unit based on the GustoMSC CJ70 design and Statoil’s "Category J" specifications.
It has an operational air gap of 69 m (226 ft) and can operate in a water depth of up to 150 m (492 ft) in harsh environmental conditions, with a maximum total drilling depth capacity of around 10,000 m (33,000 ft).
This is also the first offshore structure of its kind to fully comply with both Norwegian and UK regulatory standards, Sembcorp adds, and is uniquely suited for operation over a very large platform or in a subsea configuration.
Construction took 31 months.
