... mix. Having efficient ways of transporting hydrogen is thus of vital importance. One such alternative is to transport gaseous hydrogen in pipelines. Pipelines have been extensively used for natural gas and oil transport. There is also a certain existing hydrogen pipeline network (ca. 5000 km), however...

... the vehicle is in the initial position, the length of wire rope 2 is the longest. When winch 2 produces maximum traction, the extension of wire rope 2 is the largest. When L1=45m, F0=350kN, S=3.85*10-3m2, E=0,785*105MPa, the extension of wire rope is, dL1 = L1F0 SE = 0.052m (7) The extension of wire rope...

INTRODUCTION As wind farms approach their normal design life of 20–25 years, wind farm owners...

... is usually fatigue-driven since OWTs are exposed to long-term and variable-amplitude loading. Lifetime extension is one of the priorities of wind industry in order to reduce levelized cost of energy (LCOE). However, there is not much experience regarding this issue. DNV-GL (2016) recommends renewed lifetime...

...- normal west breakwater. Eight infrastructure modifications including breakwater or spur extension, a sheet pile wall and deepening channel were proposed for investigation. Model results indicated adding a new sheet pile inside harbor or extending the interior spur would reduce most wave energy...
