A platform supply vessel to supply offshore oil platforms.


The challenge with retrofit projects is to find a suitable location for the BWTS in an already busy engineroom. BIO-SEA by BIO-UV Group has continuously worked on reducing the footprint to eliminate the need for a cumbersome power cabinet. A BIO-SEA BWTS can fit in the most restricted of spaces.


Because every new building project is complex, finding a suitable BWTS shouldn’t be a headache. BIO-SEA BWTS was made simple: a compact plug-and-play solution for compliance and easy maintenance.

  • All components (filter, UV reactor) are mounted on a platform.
  • The control command and power supply cabinets are also mounted on the skid.
  • The electrical and hydraulic connections are optimized to be easily connected with the vessel.

BIO-SEA by BIO-UV Group: a proven combination of quality, price and efficiency

  • BIO-UV Group technology

    • More than 20 years of experience in UV technology for water disinfection ensuring optimum design and reliability.
    • UV systems designed and manufactured in France to maintain a high level of quality and efficiency while keeping full control of the total production chain.
    • Safe and sustainable solutions: chemical-free, without explosive gases, zero by-product, zero active substances and zero induced corrosion in the pipes or in the ballast tanks.
  • Best Performance

    • IMO and USCG certified, tested by first-class laboratories.
    • Efficient even with low water transmittance. With no holding time for fresh water.
    • Made with high quality materials (titanium, copper aluminum, SMO) and marine components from reliable and recognized European suppliers, providing a robust and long-lasting BWTS.
  • Best Service

    • Full support to the ship’s crew for complete understanding of the system – from detailed documentation to tailored servicing.
    • Worldwide Service team and partners remain available during and after the integration process.
    • A dedicated training facility in France for ship-owners, technical superintendents, crews and other stakeholders involved in the operation of BWTS for hands-on real-operations training.
  • Easy to use & maintain

    • Ready to use and turnkey solutions.
    • Treatment process fully automatic – there is no manual intervention required: easy to operate with low maintenance, the large touch screen simplifies the HMI.
    • Different communication protocols available (dry contacts, RS 485, auxiliary touch screen) can be fully integrated to all ship automation systems.
    • System design reduces moving parts (as well as onboard spare parts), which results in a lower operational maintenance costs.
    • UV reactors work independently, allowing the system to stay operational should one of the reactors require maintenance.
