—This study investigates the cost and benefits
associated with supplying Abu Dhabi with desalinated ballast
water brought in with oil tankers and liquefied natural gas
(LNG) vessels under different domestic water demand
scenarios. Traditionally, the ballast water is discharged directly
into the sea which has severely negative impact on the marine
environment. The International Maritime Organization (IMO)
is in the process of setting up a regulation requiring ballast
water to be treated before it is discharged. To meet the
requirement, desalinating the ballast water and supplying it to
the local residents is one of the efficient ways. We analyze water
trade of ballast water desalinated with waste heat generated
from the propulsion of Oil Tanker and LNG vessels under
different domestic water demand scenarios. Results show that
in addition to the marine environmental benefit, ballast water
trading will generate a cost saving in the range of $771.5 million
to $602.0 million between 2012 and 2030 depending on the
realized domestic demand for water in Abu Dhabi.
