Under vessel motion, dynamic responses of compliant risers, like a steel catenary riser, are no longer small displacement and small deformation problems but characterised with large displacement and small deformation instead. It is therefore difficult to directly obtain the riser global motion based...
The paper focuses on prediction of short-term environmental conditions by using an improved ANFIS method for marine operations. The hindcast data used here consists of ten-year long one-hourly time series of mean wind speed Uw, significant wave height Hs and peak spectral wave period Tp at the North...
Dr Elizabeth Lindstad from Norwegian marine research organisation Sintef Ocean, points out that the price differential between HFO and low sulphur alternatives will increase with higher crude prices, and narrow with lower ones. This is because as well as the fixed costs required to convert crude...
For better utilization of ocean and coastal space, hydrocarbon products can be stored in the floating tanks, which can be enclosed by barge system. The barge system can be moored through pile foundations. The tanks are moored through marine fenders connected to barges. In the system, hydrodynamic...
The catch of marine whitefish is typically seasonal, whereas the land based processing industry has a need for all-year stable supply of raw materials. This challenge can be met by applying fish frozen at sea. When using frozen fish, the methods employed for thawing may influence the safety and...
Model tests have been performed with four mobile offshore drilling units (MODUs) with the aim of identifying wave drift forces and low frequency damping. The MODUs configuration is different, namely on the number and diameter of columns, therefore the sample is representative of many of the existing...
Big data technologies have shown significant benefits in many sectors of society, as diverse as manufacturing, business management and health science. This report looks at the state of the art of big data technologies and their application in bioeconomy, i.e. the parts of the economy that use...
Microalgae are regarded as a promising alternative that can replace fishmeal and fish oil in aquaculture. Under N-limitation, many microalgae species change their carbon storage patterns in favor of neutral lipids (NLs) mainly in the form of triacylglycerol (TAG), but fatty acids in polar lipids (PL...
The effect of a reduced amount of emulsifying salt on the chemical and textural properties of processed cheese was studied. Reducing the amount of emulsifying disodium phosphate salt added resulted in a slight reduction in the pH, lightness and viscosity of the processed cheese. When replacing...
