Sweden's Electrolux has decided to expand a sulphur oxide emissions-reduction pilot project with Hamburg Süd.
Electrolux Global Logistics Vice President Bjorn Vang Jensen said the emissions from cargo ships moored in port is a big health problem for people living close to ports.
The electronics firm is funding a voluntary switch to low-sulphur fuel during layovers at Manzanillo (Mexico), Callao (Peru), and Iquique and Puerto Angamos (Chile).
The 7,114TEU Santa Catarina voluntarily used cleaner marine gas oil (MGO) instead of standard heavy fuel oil to operate its auxiliary engines and boilers.
Both must be running in port to supply the ship with electricity and heat.
