Inter Ocean Energy High Sulphur Fuel Oil (HSFO) is a heavy marine fuel primarily used in large vessels equipped with exhaust gas cleaning systems (scrubbers). It is suitable for main engines where emissions are treated to meet international regulations. HSFO provides cost efficiency compared to low sulphur alternatives while delivering reliable energy output for long voyages and heavy-duty operations. With proper onboard scrubbing technology, vessels can continue using HSFO while reducing sulphur emissions. Inter Ocean Energy ensures consistent supply of HSFO to support efficient marine transport, operational performance, and compliance with global shipping standards across Sri Lankan ports and routes network operations.
