Recently, Headway Technology Group (Qingdao) Co., Ltd. finished the additional tests for 2-hour holding time for USCG type approval under the supervision of DNV GL. All tests were done in 100%-130% rated capacity of OceanGuard® BWMS. With the completion of those tests, OceanGuard® BWMS now offers the shortest holding time in the market.
According to Headway’s BWMS approval project team, all pipelines are required to be cleaned between ballast and de-ballast operation, and 2 hours reached to the ceiling of the shortest interval. Furthermore, Headway mentioned that some ship operator has been asking if the “Not Applicable ” holding time means “no limitation”, it is recommended to confirm with USCG to avoid unnecessary trouble during PSC inspection.
Since there was no change of BWMS during additional tests, all delivered OceanGuard® BWMS will be able to achieve 2-hour holding time in fresh, brackish and marine water without any modification to the system.
