Comments
The SOFEC CALM system is designed to load and lift crude oil from tankers through the Butinge Terminal. It is located approximately 7.3km offshore in the Baltic Sea near the northern border of Latvia in 20m water depth. The system features SOFEC’s 12.5m diameter, 12-compartment buoy, with special considerations for the cold weather and ice conditions.
