Norwegian Offshore Service Vessel (OSV) owner and operator Golden Energy Offshore claims to have cut its operational fuel usage by 20% through the deployment of containerised SAVe Energy battery technology earlier this year following analysis of its vessel performance monitoring data, in cooperation with Kongsberg Maritime.
The fuel reduction was achieved on Golden Energy Offshore’s Platform Supply Vessels (PSV), NS Orla and NS Frayja. Monitoring was provided by the Kongsberg Vessel Performance System (VPS), using a new vessel data to Cloud infrastructure also deployed this year.
Kongsberg Maritime’s data analytics team found there was significant potential for fuel savings in Golden Energy’s operations by introducing battery power, culminating in the installation of the SAVe Energy battery system. Both vessels have now been sailing with batteries for more than six months.
“With availability of historical data of all key components onboard from the previous four years from the VPS, we had all the information needed to further configure the systems to help the Golden Energy Offshore vessels to perform at their best,” said Kongsberg data scientist Joakim Kjølleberg.
“By utilising a redundant battery solution connected to the main switchboard in Dynamic Positioning operations, we are able to reduce total engine running hours by 43%. The increased load and improved efficiency are very beneficial, helping the vessels to achieve operational fuel savings of 20%.”
The Kongsberg Vessel Performance System provides details on fuel consumption and overall energy efficiency levels, benchmarked against historical performance, to identify opportunities to minimise fuel usage and reduce emissions. Following this project with Golden Energy and feedback from other customers, Kongsberg says that the system has now been further developed to also cover battery performance monitoring.
