To assist vessels navigating polar waters, technology supplier Navis, a part of Cargotec Corporation, has introduced its MACS3 loading computer module, which automates stability calculations in compliance with the IMO Polar Code.
Navis said the MACS3 PolarCodeBasic module replaced “tedious manual calculations” previously required for tasks such as topside icing by automatically inputting stability calculations. The software takes the ship design, on-deck equipment, and cargo structure into consideration to calculate all vertical and horizontal areas in accordance with the IMO Polar Code, which came into effect on 1 January 2017.
IMO regulations require all ships to have sufficient stability when ice accretion – a build-up of layers of ice on areas exposed to freezing conditions – is likely to occur and ensure that calculations consider the extra weight of the ice.
“Reliable stability calculations are the key competence of the onboard loading computer MACS3,” said Guy Rey-Herme, head of maritime solutions at Navis. “We are now happy to assist shipowners and managers in providing an effective way to optimise the protection of their crew, vessels, and cargo when operating in these harsh environments.”
The MACS3 PolarCodeBasic module is available for all vessel types. Established in 1984, the MACS3 loading computer includes a ship library of approximately 5,000 vessel profiles and holds a market share of approximately 65% for the container vessel segment.
