Between 2015 and 2016 Pinfabb carried out a smart stabilizer project on a Tallink AS ferry, renewing the old existing SPERRY control and optimizing the stabilization performance.
Pinfabb has now released sea trial results of the Pinfabb_Eco system on the M/V Isabelle that have proven that the system can reduce 50% of the stabilizer drag, improving the cruise speed of 0.25 knots without changing the engine load.
Feedback from Tallink was that the Pinfabb system enabled the crew to keep a good level of comfort and safety onboard without the necessity to improve the engines load and the relative fuel consumption and CO2 emissions.
The sea trials were performed in navigation between Sweden and Latvia.
Pinfabb performed a full upgrade of the previous stabilizing control system on board the M/V Isabelle within a period of a few days. They supplied new compatible hydraulic parts to bring the stabilizer plant ‘back to life’. Pinfabb say that their controls can be easily interfaced using the existing hydraulic and mechanical plants, but on board M/V Isabelle they had to completely renewed the stabilizers system.
In the wheelhouse Pinfabb installed a new, intuitive touchscreen panel to replace the old analogic panel. This system provides analytical data about the stabilization and also offers suggestions in order to obtain the optimal use of fins.
The engine control room’s main analogue panel unit was also replaced with a less bulky, Modern Touch-Display. New Digital Automation (FDA) was also installed instead of the obsolete local units and all connections from the local unit to the bridge now use a single Ethernet cable. START & STOP digital buttons have been added for a simple operation by the crew, when needed.
Pinfabb also say that if the system is operated in ECO mode it can reduce fins drag and fuel consumption up to 60%, and also therefore CO2 emissions.
Pinfabb’s SRL CTO and PINFABB_ECO developer, Matteo Fabbricotti explained:
”We are very proud to cooperate with Tallink, a company that is well oriented into energy efficiency and into smart ship maintenance, the cooperation with the crew and with the management has been brilliant and precious to obtain such a good result as the 0.25 knots improvement on cruise speed when sailing with Eco software mode”.
