GOLDEN ENERGY REPORTS 20% SAVINGS WITH KONGSBERG SYSTEMS

Thursday, November 21, 2019 

Norwegian advanced Offshore Service Vessel (OSV) owner and operator Golden Energy Offshore (GEO) has reported that its long-term collaboration on vessel performance monitoring with Kongsberg Maritime and deployment of the containerised SAVe Energy battery system earlier this year is delivering operational fuel savings of 20%.

The results have been achieved on Golden Energy Offshore’s UT 776 PSVs, NS Orla and NS Frayja. Already operating efficiently with Full Picture technology packages on board, GEO and Kongsberg Maritime have been monitoring and analysing data from the ships since 2015.

Monitoring is provided by the Kongsberg Vessel Performance System (VPS) – with the new vessel data to cloud infrastructure Vessel Insight also deployed this year – enabling GEO to gain insight and transform daily operations to achieve significant fuel reductions.

Kongsberg data scientist Joakim Kjølleberg said: “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 GEO vessels to perform at their best.”

Kongsberg Maritime’s data analytics team found significant potential for further savings by introducing battery power. GEO installed the Kongsberg SAVe Energy battery system on both ships in 2019. The operational data already collected informed key installation factors including the size of the batteries to be deployed for optimal operations.

“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%. This combined with shore connection at port means that the vessels are on their way to achieving annual fuel savings of approximately 360m3, equivalent to around 1000 tonnes of CO2 and 3 tonnes of NOx,” said Kjølleberg.

Per Ivar Fagervoll, CEO, GEO, said: “We appreciate the good cooperation with Kongsberg Maritime, it enables us to reach our goals and at the same time we have a front row seat in developing Green Operations.”

Kongsberg Maritime’s SAVe Energy concept is a modular Energy Storage Unit that includes a liquid cooled battery system. It is scalable according to energy and power requirements, complies with international legislations for low and zero emission propulsion systems, and can be used for peak shaving, spinning reserve and for full battery power for offshore vessels, cruise ships, ferries, tugs and workboats.

The Kongsberg VPS enables informed decision making by both crew and onshore teams, with the potential to assist customers in lowering energy usage, fuel consumption and operating costs. It provides details on fuel consumption and overall energy efficiency levels, benchmarked against historical performance, allowing the crew and ship management to exploit opportunities to minimise fuel usage and reduce emissions. Following the cooperation with GEO and other customers, VPS has now been further developed to cover battery performance monitoring.
