19 Sept 2016: Update on USCG BWM requirements
INTERCARGO members have identified a priority difficulty to be how to meet USCG BWM requirements when their vessels visit US waters and discharge ballast water there. Following this up, an update as enclosed here was sent to members.
22 July 2015: 2nd round feedback from INTERCARGO members with BWMS already installed on their ships
It is to start the 2nd round feedback from members with BWMS already installed on their ships, focusing on 2 specific questions as highlighted by some members recently:
1. Does their BWMS on board have filters and experience any difficulties with the filters such as the filter size and general functioning;
2. For mud cleaning from ballast tanks for instance before DD, any problem with the BWMS on board.
I would also like to share with you the following feedback just reaching me from some members in the last few days with many thanks to them:
• Sampling - large number of planktons or bacteria in the remaining water where pocket at tees or branches on the main ballast pipping line, and those remaining organisms effected counting number of sampling even though BWMS running data indicated perfectly;
• Piping and pumps for aft peak ballast tank - when using GS pump for its ballasting/de-ballasting, few currently available BWMS have flow rate which can be operated with both GS pump and ballast pumps (too big flow rate differences); one member suggested it be better to size up for APT pipes to use ballast pump (same as the BWMS) even capacity of APT is small;
• After experiencing:
o Logistics and transportation of BWTS equipment and other supplemental parts are quite time consuming;
o If the repair yard is not familiar with the installation and commissioning works, their work schedule may not be planned and executed properly; also rectification period (or voyages) may be needed to sort out problems before BWTS entering in normal operation;
o After installation, BWTS may not work properly due to the complicated work and poor coordination among the venders and the repair yard.
One member suggesting:
o the repair yards be pushed to familiarize the equipment and installation works to prepare proper plans and schedule, which may be a kind of know-hows to them;
o long enough lead time (at least half a year) and detailed discussion among the venders, engineering contractor and repair yard will contribute shorter work period and better quality in the repair yard.
