Because most small workboats have very limited or no free space available in the engine room for installation of an IMO required ballast water treatment system, UniBallast introduces the Portable Ballast water Treatment Skid.
A detailed in-house study showed that it is possible to have a suitable ballast water treatment system fitted in a frame while keeping the unit compact, lightweight and with power supplied from the vessel. In this study a multi-cat has been used. This vessel with a ballast water capacity of 53 m³ has no free space in the engine room to install a permanent ballast water treatment system. The design of the Portable Ballast water Treatment Skid is based on the specifications and limitations of this vessel.
Using the specifications of the vessel and the requirements set by UniBallast, our client and UniBallast’s BWTS Selection Tool a selection of most suitable ballast water treatment systems was made. Using the operational profile of the multicat, the additional criteria for the BWTS were defined. Five of the most important selection criteria are shown below:
2. IMO Approval information (G9)
3. IMO Administration approval (G8)
4. USCG (AMS) determination
5. Maximum power consumption
With the Ballast Water Treatment System selected and verified, the specifications of it are used as design input for the skid. This skid design meets the requirements set by the DNV 2.7-1 standards for offshore containers.
The skid is easily transportable by air, sea and land because of its lifting and fastening features and its compactness.
