Hydro to Use Deepsea Delta for Production Drilling on Vilje

Petroleum Safety Authority Norway

Norsk Hydro Produksjon AS has received consent from the Petroleum Safety Authority Norway to use the Deepsea Delta for production drilling on Vilje.

The Vilje field is located in the North Sea, north of the Heimdal field. The field is being developed with two subsea structures connected to the production facility (ship) on the Alvheim field, about 19 km southwest of Vilje.

This consent relates to drilling, completion and clean-up of two wells. The activities are expected to last approximately 220 days. The wells were previously spudded with a separate seabed structure for each well.

The Deepsea Delta is a third generation semisub, completed at Rauma Repola in Finland in 1981. It has subsequently undergone a number of upgrades.

The Deepsea Delta is designed to conduct drilling, testing, completion and maintenance of exploration and production wells.

The Deepsea Delta, which is owned and operated by Odfjell Drilling, received the Petroleum Safety Authority Norway's Acknowledgement of Compliance (AoC) in February 2004.
