Energy efficient design of an SST-flowline system using a coupled dynamic analysis approach
(Peer reviewed; Journal article, 2024)The Subsea Shuttle Tanker (SST) is an extra-large freight submarine designed for transporting liquid CO2 to remote marginal fields. SST's offloading operation depth is limited to its structure integrity and economic ... -
IEA Wind Task 49: Reference Site Conditions for Floating Wind Arrays
(Peer reviewed; Journal article, 2024)The commercial-scale deployment of floating offshore wind (FOW) projects is expected to take place in a diverse range of sites that may differ significantly from existing fixed-bottom projects. FOW farms are particularly ... -
Investigating the influence of precursor combinations on the development of one-part alkali-activated binders using SiMn
(Peer reviewed; Journal article, 2024)Two-part alkali-activated materials are typically comprised of powders rich in aluminosilicates combined with solutions containing alkali silicates as activators, exhibiting properties akin to cement. However, the use of ... -
Comparative evaluation of stress concentration generated on human femur structure using meshfree software
(Lecture Notes in Electrical Engineering;994, Chapter, 2023)Norway is one of the countries with the highest registered incidence of hip fractures in the world. About 60% of the hip fractures are in the femoral neck, few in the caput and the rest are in the trochanteric region, ... -
