Hydrodynamic Model Tests With a Large Floating Hydrocarbon Storage Facility
(OMAE2019;96761, Chapter, 2019-06)The paper presents model tests with a floating hydrocarbon storage facility performed in SINTEF Ocean’s basin. The system may be considered a very large floating structure with a footprint of 300m × 310m. Hydrocarbons are ... -
Hydrodynamic testing of wind-assisted cargo ships using a cyber–physical method
(Peer reviewed; Journal article, 2021)A novel empirical method to study wind-assisted cargo ships is presented. The physical ship model, including propulsion units, interacts in real-time with a numerical sail model during free-running tests. Loads from the ... -
Hydrodynamics of Flexible Pipe With Staggered Buoyancy Elements Undergoing Vortex-Induced Vibrations
(ASME Proceedings | Prof. Carl Martin Larsen and Dr. Owen Oakley Honoring Symposia on CFD and VIV;OMAE2017-61265, Chapter, 2017-06-25)Flexible riser with staggered buoyancy elements has been widely used in ocean engineering, such as steel lazy wave riser, drilling riser, etc. Both the buoyancy elements and the riser may experience vortex induced vibrations ... -
Hydroelastic response of concrete shells during impact on calm water
(Peer reviewed; Journal article, 2023)Many ocean structures located offshore are supported by large vertical concrete columns. High and steep storm waves – in the process of breaking – may induce large local slamming loads on these columns. The present work ... -
Hydroelastic response of Froude scaled stiffened steel panels exposed to design-critical wave slamming
(Peer reviewed; Journal article, 2023)Stiffened steel panels of offshore ocean structures may experience violent wave impacts which needs to be accounted for in design. The slamming pressures are often measured in scaled wave tank tests and imposed on finite ... -
Hydrogen Enhanced Fatigue Crack Growth Rates in a Ferritic Fe-3wt%Si Alloy
(Journal article; Peer reviewed, 2018)It is well known that the presence of hydrogen in ferrous materials promotes both static fracture and affect the material fatigue crack growth rates. The latter is often referred to as Hydrogen Enhanced Fatigue Crack Growth ... -
Hydrogen enhanced fatigue crack growth rates in a ferritic Fe-3 wt%Si alloy and a X70 pipeline steel
(Journal article; Peer reviewed, 2019)It is well known that ferrous materials can be damaged by absorption of hydrogen. If a sufficient quantity of hydrogen penetrates into the material, static fracture and the material's fatigue performances can be affected ... -
Hydrogen for Europe - Final report of the pre-study
(SINTEF Rapport;, Research report, 2019)At present there is an ongoing process within the EU on how to fulfil the commitment made to the Paris agreement. The role of hydrogen, and in particular hydrogen from natural gas combined with capture and storage of the ... -
Hydrogen for maritime application—quality of hydrogen generated onboard ship by electrolysis of purified seawater
(Peer reviewed; Journal article, 2021)Maritime transport is investigating several options to reduce its greenhouse gases and air pollutant emissions. An experimental ship, Energy Observer, is using excess renewable energy to generate onboard hydrogen by ... -
Hydrogen from wet air and sunlight in a tandem photoelectrochemical cell
(Peer reviewed; Journal article, 2019)A solid-state photoelectrochemical (SSPEC) cell is an attractive approach for solar water splitting, especially when it comes to monolithic device design. In a SSPEC cell the electrodes distance is minimized, while the use ... -
Hydrogen Induced Vacancy Clustering and Void Formation Mechanisms at Grain Boundaries in Palladium
(Peer reviewed; Journal article, 2020)Hydrogen has a significant impact on the formation of vacancies, clusters and voids in palladium and other metals. The formation of vacancy-hydrogen complexes in bulk Pd and at Σ3 and Σ5 grain boundaries was investigated ... -
Hydrogen Influence on Mechanical Properties in Pipeline Steel - state of the art
(SINTEF Rapport;, Research report, 2020)The state-of-the-art report consist of an overview and a summary of the mechanical behaviour of pipeline steels (in the range of X42-X70) when exposed to electrochemical charging and gaseous hydrogen environment. Experimental ... -
Hydrogen informed Gurson model for hydrogen embrittlement simulation
(Peer reviewed; Journal article, 2019)Hydrogen-microvoid interactions were studied via unit cell analyses with different hydrogen concentrations. The absolute failure strain decreases with hydrogen concentration, but the failure loci were found to follow the ... -
Hydrogen production by water splitting using gas switching technology
(Peer reviewed; Journal article, 2020)This study demonstrates a novel “Gas Switching Water Splitting (GSWS)” technology for production of pure H2with integrated CO2capture. The reactor concept is based on the chemical looping technology where an oxygen carrier ... -

Hydrogen quality sampling at the hydrogen refuelling station - lessons learnt on sampling at the production and at the nozzle
(Peer reviewed; Journal article, 2019)Fuel cell electric vehicles and hydrogen refuelling infrastructure are developing quickly in Europe, the USA and Asia. Hydrogen quality for transport applications requires compliance with ISO 14687-2: 2012 and EN 17124:2018 ... -
Hydrogen re-liquefaction Process for Boil-off Gas Handling on a Large-scale Liquid Hydrogen Carrier
(Science et technique du froid;, Chapter; Peer reviewed, 2023)With the recent focus on hydrogen, seaborne shipping is considered an option for the large-scale transport of liquid hydrogen (LH2). For efficient shipping, boil-off gas (BOG) from the cargo tanks needs to be optimally ... -
