Rawabi 324 carrying out successful DP2 trials at offshore
As Marine industry moves into the digital and hybrid energy world, Rawabi Vallianz Offshore Services have begun upgrading our fleets by investing in new hybrid and electric vessels, as well as retrofitting current vessels with innovative smart technologies to remain competitive in the Oil and Gas market. It’s a new era where Rawabi Valianz Offshore Services embarks in line with Saudi Aramco’s digitalization program and Net zero vision to make vessel operations leaner and more efficient.
The topics of reduction in emissions, ESG & Sustainability are currently being discussed widely in all modes of media. Not a day passes when there is no coverage of these topics. Associated with them are the topics of increasing concentration of greenhouse gases, carbon dioxide emissions caused by fossil fuels, hybrid technology, renewable energy generation, sustainability of the earth’s limited resources, and so on. The issues involved are complex. Even though a very large majority of the Sustainability science community agrees on the causes of emissions, differing views do exist on ways to mitigate its adverse effects.
Sustainability is expected to influence the work done by companies/ businesses. The article provides insight into cutting edge technology, implemented, and further being optimized on a continuous basis by visionaries of Rawabi Vallianz Offshore Services with unaverred support from the leadership of the biggest oil major in KSA.
Rawabi Vallianz Offshore Services successfully completed its first hybridization upgrade for AHTS vessel. It is one of the first of its kind in the world, in the anchor handler segment. The vessel is now on hire with Saudi Aramco after her successful trials.
Albeit successful, the road to success was strewn with nerve racking problems that pushed engineers’ mental & physical capability to their limits. The technology was new & deeply customized was education intensive for RVOS engineers, Classification Society, Safety auditors and key Technology partners. Long sessions of meetings (read as heated arguments) leading into midnight, sleeping in coveralls inside engine control room to manage time, trial and error in telemetry, operations functionality colliding with fire & safety rules were some of the spectacle of challenges in RVOS’ way.
Rather than just optimizing batteries for the peak shaving, RVOS has gone up to the maximum specification of hybridization by installing twin containerized energy storage system (ESS) made up of 2.6MW power in total and transformers which are controlled and monitored via an energy management system (EMS). The battery system is supplied by Wartsila. Before hybridization to operate the vessel in DP2 mode, all four generators running at 17-20% load with open bus-tie to meet FMEA requirements and after the upgrade, the same can be achieved with one generator at 70% load with a close bus-tie on DC link. RVOS expects this system to reduce the vessel fuel consumption and carbon emissions by 25% also the vessel's maintenance requirements and improve its operational performance. With this upgrade, Rawabi Vallainz Offshore Services has now become the leading shipowner cum operator in the Middle East for hybridization projects.
