Houlder, a design and engineering consultancy with sustainability at its core, is collaborating with Blue Sea Energy, an built-in vitality answer supplier as a gas-to-power firm primarily based in Athens, to develop three progressive floating LNG-to-power barges (FSRPs) in Greece.
The FSRP barges, that are set to be operational by 2025, will effectively present greener, decrease emission baseload and peak energy to the non-interconnected islands of Kos, Chios, and Lesvos. This energy will probably be used when current renewable photo voltaic and wind vitality utilisation is at its technical limits. The barges will exchange the outdated and inefficient current diesel and heavy gasoline oil energy technology infrastructure, while assembly the EU Taxonomy and new Greek Local weather laws.
Within the present section, Houlder will full the barge designs to a stage that may obtain approval in precept by the category society, Lloyd’s Register, and can assist Blue Sea Energy with the design bundle for securing appropriate tenders from shipyards. In a earlier section, Houlder accomplished the important thing determination research on the principle energy technology engine choice, a cargo containment system, design standardisation, greenhouse fuel (GHG) discount and effectivity choices, and CAPEX, in addition to an environmental research – components such because the impression on seawater temperature and noise air pollution.
To stick to formidable EU GHG emissions necessities, the barges should generate energy effectively. In response to EU Taxonomy rules on GHG emissions for brand spanking new energy vegetation in Greece, the restrict is 270 g of carbon dioxide (CO2)/e/kWh or a 20-year common of 550 kgCO2/kWh. Houlder will due to this fact incorporate progressive, specialist options to fulfill and even exceed these requirements.
Blue Sea Energy barge options are Reconciliation Restoration Fund (RRF) eligible, the place EU funding will cowl a considerable a part of the CAPEX for these extra GHG discount measures. Because the tasks are environmental, social, and governance (ESG) compliant, the crew has additionally leveraged inexperienced funding successfully, which it has secured from a number of banks and buyers to finance the mission.
Though confirmed applied sciences are used, particular improvements will probably be included to enhance effectivity. The technical options embody maximising waste warmth restoration from the exhaust and utilizing waste warmth restoration from the engine’s cooling water system for freshwater technology for export. The barges can even maximise chilly vitality restoration from the LNG evaporation and use variable frequency drives to enhance the effectivity of motors onboard.
The crew expects to make use of a cryogenic carbon seize system onboard the facility barges. The engines used will probably be hydrogen manufacturing mix able to additional enhance sustainability because the expertise to allow this matures and there will probably be scope to issue and mix bio-LNG and renewable artificial e-LNG into the availability chain to additional scale back GHG emissions.
Jonathan Strachan, Houlder’s Ship Design and Engineering Director, commented: “The Blue Sea Energy crew has been a pleasure to work with and we’re wanting ahead to the outcomes of this fascinating mission. Floating LNG energy barges are greener than conventional energy technology infrastructure and, with novel built-in design and engineering developments, we are able to make vitality manufacturing much more environment friendly and sustainable.”
The Founding Associate of Blue Sea Energy, Konstantinos Mitropoulos, added: “We’re happy to be enterprise this progressive floating energy answer mission with Houlder. Now we have obtained electrical energy manufacturing licences from the regulator for Kos, Chios and Lesvos and we’ve got developed a robust strategy to offer all three islands with greener, lower-emission energy. Houlder has been a useful associate. The crew has main technical experience in sustainability-centric design and engineering and has labored in a sensible strategy, which has additionally complemented the Blue Sea Energy mission supply experience.”
Mark Graham, Blue Sea Energy Director of Tasks, concluded: “While the FSRP built-in energy barge is an answer that will seem novel in its strategy, the facility barge utilises confirmed tried and examined tools to cut back related design and building dangers. The FSRP nearshore answer together with its modular design and shipyard building additionally presents many repeatability profit alternatives on CAPEX, OPEX and Building schedule financial savings.”
Trying forward, there’s additionally potential to develop many extra barges and even scale up the tasks to effectively present different Greek islands and EU places with inexperienced vitality.
