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
