Rolls-Royce Battery System for Two Offshore Vessels

Rolls-Royce Commercial Marine said it has received an order to deliver a battery-powered energy system for two offshore vessels (PSVs) operated by Norway-based Golden Energy Offshore.

The delivery includes the SAVe Energy system, which was launched by Rolls-Royce earlier this month. In addition, the two vessels will receive an upgrade of the existing Rolls-Royce ship design engineering package to match the new features. This includes an upgrade of the Dynamic Positioning (DP) system, Main Switchboard and the ACON control system coupled with a Rolls-Royce Energy Monitoring system, providing a complete overview of energy usage on board.

In total, the two PSVs Orla and Frayja will receive an upgrade that benefits both the environment and the economic efficiency of the ships. Golden Energy Offshore’s goal is to achieve environmental friendly and cost effective operations for all of their vessels, emphasizing energy efficiency, sustainability and a low emissions profile in accordance with IMO’s standard for a Ship Energy Efficiency Management Plan (SEEMP). The company is among the few offshore ship operators globally that are fully ISO 50001 (Energy Management Standard) certified, which involves having a framework for measurement, registration, reporting and auditing of energy efficiency.

Golden Energy has been part of numerous pilot projects ranging from physical installations and upgrades of vessels to digital “Big Data” projects. All with clear targets to achieve environmental benefits.

SAVe Energy from Rolls-Royce is a cost competitive Energy Storage Unit that includes a highly efficient and liquid cooled battery system in a modular design. The product is scalable according to energy and power requirements, and complies with international legislations for low and zero emission propulsion systems.

NS Orla and NS Frayja operate out of Stavanger, Norway, and are well known to Rolls-Royce. Both vessels are of Rolls-Royce UT 776 CD design with oil spill clean-up capability, and they have an extensive range of Rolls-Royce equipment on board, including the Rolls-Royce Energy Monitoring (EM) system. The EM system was added to the control and automation system of these vessels and started collecting vessel data back in 2015, and has been coupled with other technology pilot projects hosted by Golden Energy Offshore.

Bygger om to fire år gamle forsyningsskip til hybrid
De to offshoreskipene Orla og Frayja får batteripakker og blir hybride fra 2019. Batteriene kan fungere som "spinning reserve".

Rolls-Royce har fått kontrakten med Golden Energy om å levere en batteripakke på 896 kWh til hvert av de to søsterskipene "NS Orla" og "NS Frayja".

For Rolls-Royce er kontrakten et bevis på at det var riktig strategi å bygge opp egen produksjon og sy sammen totale kraftpakker.

– Vi har over 40 forespørsler på hybridisering av eksisterende offshoreskip. I tillegg kommer mange nybygg. Vi må hele tiden vurdere ressurssituasjonen. Slår flere av prosjektene til, må vi øke kapasiteten, sier teknisk produktsjef for energilagringssystemet Save Energy, Jens Hjorteset i Rolls-Royce.

Rolls-Royce Power Electric Systems i Bergen annonserte tidligere i augustat de vil produsere batteripakker selv. De førstekontraktene til et fiskefartøy og to offshorefartøy var inngått.

Nå kommer to systemer til Golden Energy Offshore i tillegg.

Kraftpakker i dekkshus
Hjorteset mener at de har utviklet et svært innovativt system til de to Golden Energy-fartøyene.

– Batterier og kraftelektronikk plasseres i solide dekkshus. Elektronikk og batterier er i separate rom, atskilt med brannsikring i A-60 klasse. De er godkjent som backup-generatorer ved DP-operasjoner, det vil si at de fungere som «spinning reserve», sier Hjorteset til TU.

Batterier og elektronikk blir plassert i det som på folkemunne kalles containere. -Det er ikke vanlige ISO-containere, men spesialbygde hus i kraftigere stål og med brannsikring for å tilfredsstille klassekrav til reservekraft.

Dekkshuset måler 3,3 meter i høyden, 8,2 meter i lengde og drøyt 3 meter i dybden.

EIOF - Awarded ship management agreement for two platform supply vessels

Aker BP has awarded Eidesvik Offshore ASA ("Eidesvik") a ship management agreement for two supply vessels in operation on the Norwegian continental shelf("NCS").

NS Orla and NS Frayja are the vessels that will be operated by Eidesvik. The contract is firm for three years with options thereafter. Both vessels were built in 2014, and in 2019, battery hybrid solutions were installed on board the vessels. The hybrid solutions have resulted in more fuel efficient operations, and contribute to more environmental friendly operation of vessels on the NCS.

"Eidesvik has been awarded the contract in competition with other suppliers, and we are very pleased with the confidence Aker BP is showing us", says CEO & President in Eidesvik, Mr. Jan Fredrik Meling. "The award of the ship management for two modern vessels with hybrid solutions, in addition to our own vessels in operation, will contribute to a further development of Eidesvik's top competence and experience of operation of environmental friendly tonnage". The vessels will be operated from Eidesvik's office at Bømlo.

"The change of ship manager for these vessels is part of a long-term strategy, where we have chosen our strategic partners for the delivery of supply vessel services. We have great confidence in Eidesvik and that they will actively work to optimize the operation of the vessels as part of our common long-term initiative to redefine the supply chain by increased cost efficiency and sustainable solutions", says VP for Logistics and Marine in Aker BP, Gunn-Elin Hellegaard.

The vessels have NOR flag and employ 56 seamen. The contract will commence October 1, 2020.
