DNV has been collaborating in a joint industry project (JIP) evaluating fuel technology options and energy-efficiency measures. The Roadmap towards a Zero-Emission Vessel project centres on a defined concept for two newbuild tankers, an MR and LR2 tanker
The DNV fuel technology assessment JIP also included Deltamarin Ltd as ship designer, Minerva Marine as vessel manager, and energy company Total as a charterer.
The case study centred around two 2020-built tankers: an MR (about 39,000 dwt), trading short voyages mainly in Europe; and an LR2 (about 115,000 dwt), trading worldwide.
“We have performed a quantitative cost-benefit analysis for fuel options and analysed the potential impact of these fuels and technologies on the MR and LR2’s greenhouse gas emissions,” said DNV tanker director Catrine Vestereng,
“Our report on the project also discusses how integrating emissions abatement measures like rotor sails and solar panels could impact on ship design, safety, technical complexity and more.”
Fuel consumption for the MR and the LR2 is based on simulating the case ships’ operating profiles as if they were in Minerva Marine’s fleet and built to Deltamarin’s designs. The study factors in speed distribution, propulsion requirements, main-engine fuel consumption/specific fuel oil consumption, energy losses, engine maker’s tolerance and other fuel characteristics.
The JIP assessed 21 options and the findings were split between environmental and financial.
