Rolls-Royce to install energy management system on nine Havila vessels

Rolls-Royce Commercial Marine has been awarded a contract to install its energy management system (EMS) across nine vessels in the Havila Shipping fleet.

Rolls-Royce said on Tuesday that the energy management system would be installed on four anchor handling tug supply (AHTS) ships, four platform supply vessels (PSV), and one rescue and recovery vessel (RRV).

The company said that the installations on Havila’s fleet were scheduled to be up and running by March 1, 2019.

The EMS was first introduced in November 2017 by Rolls-Royce as part of a suite of vessel intelligent asset management products and has since then been installed on over 50 vessels.

A key benefit of the EMS is that a ship’s crew can see the effect that running machinery has on fuel consumption in real-time.

The system’s sensors assess fuel consumption against, amongst other things, vessel speed, electrical load and the relationship between propeller pitch and RPM. Existing DP sensors are also used to calculate the external forces – wind speed and wave force – acting on the vessel.

Olav Haug Vikebakk, deputy managing director, Havila Shipping, said: “Our vessels operate various Rolls-Royce propulsion and machinery systems, so its EMS is a perfect fit for us.

“The tool allows us to implement operational changes in real-time to immediately reduce fuel consumption and reduce unnecessary running hours on equipment like generators.”

Marco Camporeale, general manager of ISM solutions at Rolls-Royce, added: “The Rolls-Royce EMS allows all parties to more fully understand the performance of their vessels. The technology is applicable to any vessel-type operating equipment from any manufacturer.”

“While it is too early to evaluate the operational and performance data for the first Havila ship, Rolls-Royce has EMS customers reporting annual fuel savings of up to 20%,” the company said.
