For ships awaiting transit or at anchor near landfall, the offshore charging technology will allow drawing power from a stationary offshore unit, eliminating the need to burn fossil fuels while waiting in line. 

The Panama Canal handles around 14,000 vessels annually, making it a key shipping route.

Shore-to-ship power or “cold ironing” is an electrical power supply provided to ships. Instead of running the engines onboard to power the essential systems while docked at ports, shore power facilities allow ships to connect to the local electrical grid.  

Stillstrom and the Panama Canal Authority will also conduct a joint feasibility study to assess the potential for offshore charging facilities in the region.
