Technology group Wärtsilä has signed a project agreement with Monaco-based ship operator Marfin Management for the first hybrid installation for a bulk carrier. Under the terms of the agreement, which represents a new technology benchmark for the marine sector, the innovative system will be installed on the Paolo Topic, a 59,000 dwt bulk carrier. The project agreement was signed on 8 July in Monte Carlo, Monaco.

Wärtsilä’s hybrid power module, the Wärtsilä HY, will ensure the seamless integration and control of the technologies to be installed, with the ship’s various existing power production systems. The vessel’s power and propulsion package encompasses a Mitsui MAN B&W 6-cylinder 50ME-B9.3 main engine of 9000kW output, plus three Daihatsu 60Hz 650 kVA 3-phase diesel-electric gensets.

This is made possible by the use of a dedicated Energy Management System (EMS) that will have overall control of the engines, batteries and power distribution. The project includes the first example in the marine industry of the installation of solar panels on the weather deck.

“This new technology development, utilising a combination of engines, solar power and batteries, represents a milestone for the industry and is made possible by the Wärtsilä HY integration,” says Giulio Tirelli, Director at Wärtsilä Marine Business. “Thanks to the fully integrated solution, we are able to raise the bar in terms of economic competitiveness and environmental performance.”

The integrated solution is expected to deliver a drastic reduction in fuel consumption and maintenance costs. This, combined with the highly advanced level of environmental sustainability, will make the Paolo Topic the global fleet’s most technologically advanced bulk carrier. Furthermore, operational stability and increased efficiency will be ensured in all operating conditions, including loading and unloading.

The Paolo Topic features 4 x SMAG Peiner electric hydraulic dual scoop grabs, and 4 MHI electro-hydraulic deck cranes. The intensity of cargo handling and the associated electrical load on an Ultramax self-unloader meant that fuel consumption in port could be expected to exceed six tonnes per day during loading, and rose above ten tonnes when discharging at the maximum rate before the hybrid installation.

“We are pleased to have found like-minded partners to bring new technology and innovative thinking onboard to help improve our environmental performance and leading the way towards a more sustainable future. We will be able to provide our customers and partners with the most advanced vessel performance and environmental quality without compromising on operational effectiveness and flexibility,” says Alex Albertini, CEO at Marfin Management.
