The GASS project will only succeed with data from vessels. And the data keeps coming from Grieg Star and SinOceanic Shipping - our main shipowner partners.
The last few months have primarily been about sourcing and retrieving data. Grieg Star has contributed by retrieving historical data from 14 vessels over ten years and sharing it with NAVTOR for Simula Research Laboratory to start the machine learning and Digital Twin. The historical data includes sensor data from their fuel consumption monitoring system onboard, as well as navigational data on position, speed, and weather.
Innovation and Sustainability
Grieg Star is the ship management arm of Grieg Maritime Group, managing or acting as owner's representative for 31 vessels within the Open Hatch segment. All the ships are part of the G2 Ocean pool, a joint venture with Gearbulk and the world's largest Open Hatch shipping operation.
Intent on succeeding in their decarbonisation journey, Grieg Star is involved in several innovation projects.
"Shipping faces tough requirements for decarbonisation, and Grieg Star has high ambitions in this area. We do, however, realise that we can not do it alone. Collaboration across the industry, with suppliers and academics, will be crucial to finding the best solutions. We believe the GASS project can make a difference, and we are happy to contribute with what we have – shipping knowledge and many years of data collected from the vessels," says Principle Engineer Henning Rebnord at Grieg Star.
We are genuinely excited to have Henning and his colleague, Project Engineer Marte Waage Haga, as Grieg Star's dedicated contacts for the GASS project. Their work and assistance are crucial to the project.
Flowmeter and Motion Reference Unit sensors
Together with the partner ScanReach, we are planning to install MRUs on two of Grieg Star's dedicated test vessels. Before the GASS project kicked off, we were not aware of the importance of MRUs in our work to optimise propulsion and reduce oil fuel consumption. Providing real-time fuel consumption is much easier to understand.
We have also learned that, with the ongoing IMO reporting requirements, most of the vessels in the project already have flowmeters hardwired with data input to their chosen vessel performance software. This is not the same for MRUs. We need MRU data primarily to find the correlation between sea conditions (waves), response to vessels, and consumption of the main engine (ME).
Digital twin
Even though we are still at the beginning, the GASS project is really starting to form. We've identified and started sharing our historical data to enable the creation of the digital twin. At the same time, we are collaborating with project partners to ensure we can provide new data through the project; while also improving the quality of the data we continually retrieve from our vessels.
It's been great collaborating with partners across maritime value chains, and we find it rewarding to learn from others along the way. Hopefully, we will gain more insight into which parameters we need to adjust onboard to achieve higher energy efficiency and contribute to solving the emission challenges the shipping industry is facing.
Throughout the project, GASS will also receive significant ship propulsion and fuel consumption data from ship owners other than Grieg Star and SinOceanic Shipping.
