The Internet today runs on a complex routing protocol called the Border Gateway Protocol (BGP). BGP is a policy-based protocol, in which autonomous Internet Service Providers (ISPs) impose their local policies on the propagation of routing information. Over the past few years, there has been a growing consensus on the complexity and fragility of BGP routing. To address these challenges, we pres...

Wire arc additive manufacturing (WAAM), also known as directed energy deposition (DED) process, is an efficient technology, offers high potential to rapidly fabricate large-scale parts with complex geometries layer-by-layer. However, the fundamental understanding of fatigue behaviour such and material requirements need be significantly improved at all levels before this unique technology can im...

We investigate the potential for using seasonal climate predictions marine risk assessment in Barents Sea. Marine is based on diagnostic of probability extreme conditions and their consequences to identify time regions vulnerable hazards. The information operationally provided by Det Norske Veritas (DNV) support sustainable safe activities. So far, was historical observations. Here, we implemen...

Buckling damage is one of the biggest safety issues for subsea pipelines. behaviors pipeline with integral buckle arrestors under external pressure are studied experimentally and numerically herein. Pressure chamber tests four full-sized identical thickness different diameters presented. An emerging vector form intrinsic finite element method (VFIFE) introduced to simulate whole buckling proces...

Abstract We present a full-scale validation study of an optimal power open-loop wind farm control schedule (WFCS) using full row turbines (Row-A) at the Lillgrund offshore as demonstration case. The derived WFCS is conditioned on ambient speed and direction. WFCS’s are developed DNV DTU numerical models LongSim Fuga. Prior to implementation, controllers tested by comparing results, based Fuga o...
