January 30, 2018: Rolls-Royce Commercial Marine recently won an order to deliver battery-powered energy system for six offshore vessels (PSVs), which was built by the COSCO Guangdong Shipyard, China.

The delivery includes the energy storage container system (ESSU), an upgrade of the existing Rolls-Royce ship design engineering package to match the new features, upgrade of the dynamic positioning system (DP) and the ACON control system, and the new Rolls-Royce energy monitoring system, which will provide a complete overview of energy usage onboard.

Recently, US-based SEACOR Marine Holding entered into a joint venture with China Cosco Shipping Group. The new venture, SEACOSCO took over eight offshore vessels, which are currently at the COSCO Guangdong Shipyard to undergo a makeover.

According to Rolls-Royce, ships were ordered in 2013 and 2014. Interestingly, the new owners of the offshore vessels decided to give six of the Rolls-Royce designed vessels an environmental upgrade, with an option for a further two. 

SEACOR is expected to take full operational responsibility for the vessels, and add them to their current fleet. 

John Gellert, president, CEO and director of SEACOR said: “By combining a proven and advanced design, best in category accommodations, and the innovative Rolls-Royce battery system, the vessels will be highly marketable across all major offshore energy regions worldwide.”

Asbjørn Skaro, director digital & systems – commercial marine of Rolls-Royce said: “We want to see the vessels in operation, hence we made investments. These are advanced and modern ships, and we strongly believe that the new energy system will make them stand out from the crowd in the market. They will receive an upgrade that benefits both the environment and the economic efficiency of the ships.”

Meanwhile, the vessels consists of Rolls-Royce UT 771 WP design, and have the characteristic of Wave Piercing bow. The bow reduces wave resistance during rough conditions, resulting in a smoother ride than traditional designs, reduced fuel consumption and increased onboard safety.
