A RO/RO combination carrier chartered in by Halliburton subsidiary Halliburton AS is to be retrofitted to operate as an LNG dual fuel vessel and will also get a shore power upgrade.
The goal of the project, which is receiving support from the Norwegian NOx fund, is to upgrade a 20-year-old vessel with modern environmental credentials that will significantly reduce its CO2 and NOx emissions both at sea and during harbor stays.
The work will be carried out under a turnkey retrofit contract signed by Halliburton AS with Tønsberg, Norway, headquartered Høglund Gas Solutions AS and involves the 1999-built Hannah Kristina. Able to carry dry bulk, wet bulk and general cargo, it is owned by Base Marine Norway AS and under technical management by Larvik Shipping AS while Halliburton is the end-charterer.
“By utilizing Hannah Kristina, Halliburton has moved huge amounts of goods from road to sea, reducing the emission of CO2 and NOx,” says Jean-marc Lopez, Vice President of Halliburton AS. “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.”
Høglund is collaborating with long-time partners HB Hunte Engineering GmbH for the naval architecture work and Fiskerstrand Verft AS for the shipyard side of the project. The entire project will be classed by DNV.
Høglund’s contract scope includes the supply of a 250-cubic-meter capacity FGSS with a dedicated Gas Control and Safety System to serve the vessel’s already installed dual-fuel main engine with natural gas.
The shore-power upgrade will be used to power the vessel while berthing and to charge its existing Energy Storage System (ESS). 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 seamlessly integrated into the vessel’s existing Automation System (IAS), Power Management System (PMS) and ESS control system which were delivered and installed by Høglund in 2018.
To implement the appropriate IGF Code safety measures, Høglund will combine its gas, power and automation solutions know-how with HB Hunte’s expertise in naval engineering to perform modifications to the vessel that will include the adjustment of the mooring arrangement in the LNG tank area and an upgrade to the ventilation system.
The delivery of the retrofitted vessel is expected to take place in March 2022.
