Sharjah repairs

Albwardy Damen successfully completed its first hybridization upgrade for Rawabi. 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.

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 264 batteries/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, Albwardy Damen has now become the leading shipyard in the Middle East for hybridization projects for offshore operators.
