GloEN-PatrolTM Ballast System

As a representor of the worldwide operating company Panasia we distribute the ballast water treatment system GloEN-PatrolTM. Our systems are basically consisting of a backflushing filter- and a disinfection unit. These provide a UV sterilization how it is also similarly used in the disinfection of drinking water.



BWT System for 150 m3/h

Our systems can e offered in the dimensions of 150 m3 / h to 6,000 m3 / h ballast water to be processed. Our systems can be set up as a module or as single components. The modules themselves are variably configurable in length, width and depth according to the available space offer and therefore are also suitable for small ships with regard to price and further aspects.

Our systems are compliant with the IMO BWM-Convention, Annex D, Regulation D-2 Ballastwater Performance Standard. They are type approved in compliance with the guidelines for approval Ballast Water Management Systems (G8) of Res. MEPC.125(53). Furthermore they meet the IMO MEPC in accordance with the procedure for approval of Ballast Water Management Systems that make use of active substances (G9) resolution of Res. MEPC. 1268(53). Last but not least the systems are compliant with the US Coast Guard regulations of the State California and they are certified by the DNV concerning explosion protection and prevention according to the ATEX Guidelines.

General aspects of the GloEN-PatrolTM Ballast System

Technical aspects are covered on this page below.


  • Is the GloEn-Patrol System type approved in compliance with G8 or G9?
    We were approved in compliance with both of G8 and G9.
  •  
  • In case that the system is approved in compliance with G9: What chemicals are in use?
    We don't use any chemicals. Our system consists of Filter and UV which is a 100% physical treatment type. Actually just G8 Approval is enough for us, but we applied for G9 Approval in order to prove our equipment's reliability, safety and environment-friendliness.
  •  
  • What organization carried out type approval?
    Korean Flag State Approval, DNV ATEX Explosion proof certificate and The Netherlands Flag State Approval
  •  
  • When the type approval has been received?
    On 04/12/2009 for Korean Flag State Approval

    On 08/06/2010 for ATEX Explosion proof certificate by DNV

    On 10/08/2010 for The Netherlands Flag State Approval
  •  
  • Do you know how many states are left until the IMO "International Convention for the Control and Management of Ship's Ballast and Sediments" is ratified?
    Until now (31/10/2010) 27 Countries and 25.34% ratified.
  •  
  • Does the GloEn-Patrol System fulfill the USCG regulations of the State of California?
    Our test results fulfill the USCG regulations of the State of California and will apply for it. According to USCG, there are no BWMS that have been type approved by the USCG. Some makers have systems on ships that are accepted into the USCG Shipboard Technology Evaluation Program (STEP). However, STEP is an agreement between the shipowner and the USCG. There is no "certificate" issued to the BWMS maker.

  • What is your actual delivery time of a GloEn-Patrol System?
    3 Months after drawing approval.
  •  
  • Is the power consumption of your systems same in river/fresh water and salt water?
    Our system is same power consumption and no problem in river/fresh water and salt water. But, Electrolysis type is not operated in river/fresh water.
  •  
  • What is the life span of the UV-lamps?
    4,000 hours based on operating time. It can be calculated 4~6 years according to ballasting and de-ballasting time.
  •  
  • Are the UV-lamps working in a spectrum of 254 nm?
    210~280 nm.
  •  
  • How many lamps you have in a lamp unit?
    8 for 250m3/h, 12 for 350m3/h, 18 for 500m3/h and 24 for 700m3/h.

Filter Unit Description

Filter Unit Description The water enters through the inlet pipe into the filter area and flows through the cylindrical filter element from inside out. The filtration takes accumulating on the element surface causes pressure differential to develop across the filter element. When this pressure difference reaches a pre-set value, the back-flushing mechanism is operated. The back-flushing begins when the filter element reaches a pre-set value or a pre-determined lapse of time. The back-flushing takes between 10 to 30 seconds. During the back-flushing cycle the filtered water is not interrupted and continues to flow downstream of the filter in the normal manner.



Back flushing mechanism

  • Back flushing is operated by the differential pressure of 0.35 bar between inlet and outlet.
  • The pressure is checked by pressure sensor at inlet and outlet.
  • Back flushing mechanism is operated every 50~60 minutes at normal seawater condition.
  • After back flushing, the differential pressure between inlet and outlet is 0.05~0.1 bar and the filter return the normal working condition.
  • The filter and back flushing mechanism is repeated automatically.
  • Also back flushing pump installed at the discharge line and it is effective for cleaning.
