CFD simulations were carried out on the 1:40 model of the INO WINDMOOR floater in regular waves to extract hydrodynamic loads, both on the structure, the single columns and sections from each column. Three different approaches for the platform motion were used, (i) fixed, i.e., restrained from...

Bygg regnes for å være en «klimakjempe» globalt og nasjonalt, og tekniske systemer utgjør en betydelig andel av klimagassutslippene. Det er i dag ikke vanlig praksis å inkludere tekniske systemer i klimagassberegninger for bygg, eller å hensynta klimagass ved valg av løsninger og materialer for...

Digital twins of additive manufacturing processes aim to provide process engineers with the input they need to control the quality of the build process, and to support certification of the produced part. This often involves the collection and analysis of huge amounts of data (data-driven modelling...

As more and more critical parts are being fabricated via additive manufacturing (AM), there is an increasing need to ensure that the geometric and material properties of the parts conform to certain requirements. Currently this need is addressed by expensive, time consuming, and environmentally...

Of the two main geometric representations used in computer aided design, namely parametric and implicit representations, parametric representations have been the most dominant since their initial use in computer systems of the 1960s. This was mainly due to them being simple to evaluate, making...

Marine plastic pollution and continuous capture of marine animals, so-called “ghost fishing”, by abandoned, lost, or otherwise discarded fishing gear (ALDFG) are global concerns. This study investigated whether biodegradable polylactic acid (PLA) monofilaments can be used to replace conventionally...

Marine pollution by lost, abandoned or otherwise discarded fishing gear (ALDFG) often has negative impact on the ecosystem through plastic pollution and continuous capture of marine animals, so-called “ghost fishing”. ALDFG in pot fisheries is associated with high ghost fishing risk. The snow crab...

Since the late -90's hydrogen embrittlement in Norwegian subsea infrastructure for natural gas transport due to hydrogen from cathodic protection has been a challenge for the pipeline operators and energy companies. Through an intensive period of research and development the industry has learned...
