Starting on July 1, a 5,000 twenty-foot equivalent units (TEUs) container vessel calling at both ports will save $700 on port entrance fees and $365 on achorage fees.
The port commissioners of the BPA are also introducing a regular barge service for container cargo,linking BNP with the current Busan port.
The "two port calling-system" will be in place for two years.
The barge-shuttle service will begin as soon as a private operator has been contracted.
Tenders for the service are expected to be invited soon.
BPA's public relations office said the BPA would cover any operational losses incurred by ther barge operator.
The intention is that each barge trip should carry between 150 and 200 TEUs.
