The MACS3 loading computer ensures safe and optimal loading/discharging operations of cargo and ballast for all vessel types such as container vessels, bulk carriers, and multi-purpose carriers. MACS3 provides a wide range of calculations related to hydrostatics, intact stability, and longitudinal strength which is then used to offer advice on loading and stowage, ballast water distribution, ballast water exchange, damage stability, and grounding scenarios. Ship crews and planners can rely on compliance with the current IMO regulations and constant updates with regard to dangerous goods or ship-specific lashing rules.

With a direct interface to shore-based stowage planning solution Stowman DS, MAC3 enables optimal loading of the ship with energy-efficient trim optimization through cargo instead of ballast water. This in turn results in improved utilization of the ship. MACS3 Connected allows for loading computer data in the cloud to be accessed by various parties of ship operations.
