The National Iranian Tanker Company (NITC) is planning to cut energy use by 28% to reduce greenhouse gas emissions from its vessels.
The company said voluntary speed reduction would bring a 10% fuel cut and reduced hull roughness would minimise fuel use by 5%.
The tanker company is also considering propeller roughness and propeller vortex loss recovery, speed optimisation and main engine fine tuning which would further cut fuel use by 3%, 5% and 2%, respectively.
NITC said it intends to apply silicon antifouling to reduce hull resistance, to reduce fuel consumption by 2.1%.
Modification of propeller edge and installation of Cap Fin propellers would also result in a 6% fuel save, the company said.
NITC said it has formed a partnership with international climate change consultancy Carbon Limits to help its climate mitigation efforts.
