Island Offshore — in which the Edison Chouest group is a partner — and the North Sea RLWI Alliance have been awarded a Frame Agreement for Light Well Intervention services from Statoil. The Frame Agreement duration is three years plus a one year option. The first Purchase Order issued under the Agreement has a value of over 300 million NOK.
Island Constructor, which started operation in 2009, will be utilized. The unit is designed to operate in water depths of up to 600 meters, and is currently operating in the North Sea (both NCS and UKCS).
The North Sea Alliance was formed in 2004 to provide integrated wireline services to the growing subsea intervention market. The alliance currently operates three monohull vessels specifically designed for intervention tasks. Approximately 50 well interventions are performed each year, providing services such as scale milling, gauging and logging operations, plug setting and re-perforating requirements. Island Offshore is furthermore providing services such as engineering in conjunction with the intervention activities also including tree on wire operations. Island Offshore and the North Sea RLWI Alliance are currently the world’s leading RLWI providers and have to date executed close to 150 well interventions.
