As a consequence of the fuel world crisis the necessity has arisen to operate VLCC (very large crude oil carrier) in service at the lowest possible costs. Analyzing operating costs it has resulted that, as far as tankers are concerned, a remarkable economy can be achieved reducing the ship's speed and consequently fuel and luboil consumption. The results are reported of the experimental researches carried out to bring to the optimum engine behaviour at low outputs, both from operation and from cylinder liner lubrication and wear point of view and data gathered up to now by running some VLCC at reduced rate. Operation results are not yet complete to draw final conclusions. Therefore the authors, who are associated with a shipowner's company and an engine builder cmpany, reserve themselves to report, when presenting the paper to the Congress, about the further elements that will come up in the operation period at low rate from September '76 to April '77.
