Norwegian Dynamics product
CYGNUS Basic PHC
High-capacity passive heave compensation for heavy subsea lifts beyond the standard RIGEL range.
CYGNUS is the wide-range passive heave compensator in the Norwegian Dynamics product family. It is intended for heavy subsea lifts where capacity flexibility matters more than the most compact footprint.
Use CYGNUS when
The lift is subsea, the required load range is above RIGEL, and passive compensation is preferred over active control.
Compare with RIGEL
RIGEL remains the compact passive choice up to 1,000 t. CYGNUS extends the basic passive range for heavier cases.
