Høglund to deliver dual-fuel retrofit and shore power upgrade for ro-ro combination carrier
A partnership between Høglund Gas Solutions and Halliburton will provide a turnkey retrofit of the ro-ro combination carrier MV Hannah Kristina. The project aims to improve the vessel’s environmental footprint by converting the marine diesel oil to dual fuel by supplying an LNG fuel gas supply system (FGSS) alongside an upgrade with shore power connection. The vessel is owned by Base Marine Norway, under technical management by Larvik Shipping, and Halliburton is the end charterer.
Høglund will lead the project, which will require extensive collaboration between several parties – including naval architects, engineering teams, a retrofit shipyard, various suppliers, class society flag state and the vessel owners and operators. Høglund will collaborate with long-time partners HB Hunte Engineering and Fiskerstrand Verft for the naval architecture and shipyard elements of the project, respectively. The entire project will be classified by DNV.

The contract outlines a 250m³ capacity FGSS with a dedicated gas control and safety system to serve the already installed dual fuel system with natural gas.
For the shore power upgrade (which will power the vessel during berthing and charge the existing energy storage system), Høglund will supply and install a package consisting of shore connection cabinets of 690V/600kVA compatible with state-of-the-art shore power supply, following IEC80005-3 standards. Both systems will be integrated into the existing automation system, power management system and ESS control systems on the vessel, which were delivered and installed by Høglund in 2018.
Høglund will work with HB Hunte to perform further modifications on the vessel. These will include the adjustment of the mooring arrangement in the LNG tank area and an upgrade to the ventilation system, among other conversions. Delivery of the retrofitted vessel is expected in March 2022.
With the use of LNG and battery power, the 20-year-old vessel will significantly reduce its CO2 and NOX emissions – while at sea and during harbor stays. Supporting the project is the Norwegian NOX Fund – a partnership between the Norwegian government and the private sector, committed to reducing NOX emissions in Norway.
“The technological and environmental transformation of shipping over the coming years is one of the biggest challenges facing our industry,” said Philipp Ulrich, senior project manager at Høglund. “To achieve this transformation in a commercially viable and minimally disruptive way, meaningful and well-coordinated collaborations are essential. I’m proud that Høglund has been chosen for this project and we are looking forward to leading a consolidated and collaborative effort by working with this diverse set of stakeholders.”
“By utilizing Hannah Kristina, Halliburton has moved huge amounts of goods from road to sea, reducing the emission of CO2 and NOX,” added Jean-marc Lopez, vice president of Halliburton. “With the conversion of Hannah Kristina from diesel to LNG and shore power, we take the reduction of CO2 and NOX a step further, in line with our strategy to continue to reduce the environmental footprint of our activities.”
