Built for the deck, not the plant room
Taking a generator offshore means accepting constraints that onshore projects never face: restricted deck space, salt-laden air, limited maintenance windows, and a classification society that must approve every detail before the unit is accepted.
Cunmi offshore packages are designed from the deck up. The container envelope is a standard ISO footprint, so it ships on any vessel and lands on any platform with the crane capacity already available. Everything inside — engine, alternator, switchgear, fuel system, fire protection — is pre-installed and factory load tested.

Engineering that survives the environment
Marine-grade construction
Marine C5 grade corrosion protection with stainless-steel external panels, specified for salt-laden and humid atmospheres.
Deck-ready handling
Container Safety Convention plate, sea-fastening points and crane-certified lift frames for vessel and platform transfer.
Bunded fuel containment
Internal day tank sits inside a 110 % bunded enclosure with high-level alarm and remote fill connection.
Integrated switchgear
LV or MV switchgear, synchronising panel and UPS circuit installed and tested in the factory to reduce offshore commissioning hours.
Designed for 50 °C
Oversize radiators, tropical-rated alternators and insulated exhaust systems for hot, humid offshore climates.
Reduced deck maintenance
Service doors on both sides, slide-out radiators and single-source spares to minimise helicopter-supported maintenance.
Where offshore containers are deployed
Oil & gas platforms
Continuous or standby power for platform drilling and accommodation loads.
FPSO and vessels
Continuous or standby power for marine auxiliary and emergency power.
Ports and terminals
Continuous or standby power for shore power and terminal backup.
Offshore support vessels
Continuous or standby power for DP-class auxiliary generation.
