UniBallast has developed several concepts for Port Based Ballast Water Reception and Treatment Facilities which are easy to integrate, operate and providing ports with competitive advantages towards ship owners. One of the concepts, the mobile version, works with barges that collect ballast water from ships -even outside the port on open sea- which transport it to a larger storage and/or treatment facility.
Advantages are that ships do not have to wait for treatment when de-ballasting, the concepts ensures that de-ballasting flow for treatment is similar to the ballast water pump’s pumping capacity, making sure that ship’s operations are not limited by the in-port treatment operations. Ship owner’s responsibility ends immediately after discharge, vessels are not required to wait for actual treatment and IMO/USCG required holding times for discharge. For a complete regenerative system treated ballast water can be reused for ballast water intake by other ships.
UniBallast has developed an IACS type approved Universal Ballast Water Port Connector (UBPC) for discharge from ship to the collection barge. The UBPC is available in various sizes from 4″ – 12″ or 20” or more upon request, depending on the flow capacity needed, and can be installed in the ship’s hull or on deck. Outside a flexible rubber hose connects the ship to a treatment facility, e.g. a collection barge, portable treatment container or other port reception facility. Inside the UBPC has a tie-in to the existing piping of the ship’s ballast water system. The ship’s own ballast water pump is used, so there is no loss of flow capacity compared to the normal ship’s ballast water discharge operation.
