The patented Subsea Storage Unit (SSU) solution enables storage of crude oil, chemicals and produced water on the subsea floor.
The SSU is a gravity based storage unit that employs the new concept of a flexible bag protected by a dome ensuring long-term competitiveness and continued profitable development of the petroleum resources. The system offers a safe, more cost-effective method of developing subsea fields in extreme weather zones or in the Arctic where ice is prevalent.
How it works
The SSU consists of a collapsible bag containing the entire stored volume, which eliminates contact between stored medium and sea water. The bag is protected by a protection structure (dome) which accommodates the entire volume. Hence, there is no need to design against pressure and the unit can be deployed at any water depth.
The Subsea Storage System can be applied during well testing and early production start-up with the flexibility to add on storage capacity as the production rate increases and additional structures and multiple SSUs can also be incorporated during the lifetime of a production system. The storage is flexible in size depending on field needs during development, expansion and end of field.
