West Hercules is a fully-winterised rig with extensive experience from drilling operations in cold climates and Arctic areas. It can be used in summer or winter, and has been used for several seasons in the Barents Sea.
Transocean Enabler is also specially-designed for operations in cold climates and meets the most stringest environmental requirements, DNVGL’s ”Clean Design” classification. It is equipped with the best safety and purification systems, fully-automated computer control of the drilling operations, and heated decks and superstructure. Their environmental footprint is minimal and they emit no harmful substances to the sea.
Below, we present the technical features of Songa Enabler, the first exploration rig used by us to explore the Barents Sea in 2017. Most of these specifications also apply to the rigs currently in use.
When the exploration campaign in the Barents Sea began in 2017, “Songa Enabler” established several new world records, including the most advanced automated drilling control (ADC) system ever installed on a rig, and the first ADC system on a floating rig. ADC monitors three main parameters: drilling fluid, which is the primary barrier to preventing blow-out; any leakage from the well; and early kick and loss detection, using artificial intelligence. These systems are in addition to all the other systems and barriers we have on all other drilling rigs on the Norwegian continental shelf.
