The ECO-Ship is commercially viable

Compared to a conventional Oshima OHBC, the ECO-ship requires an additional investment of about 23 MUSD

This extra investment is expected to be earned back within 10 years

The ECO-ship improves the expected net present value before tax by 38 MUSD over a lifetime of 25 years
