INSIGHTS DA NSG
OrcaFlex, digital twins e fluxos de trabalho assistidos por IA
Na NSG, OrcaFlex, digital twins e inteligência artificial já fazem parte da rotina de engenharia offshore. Mas o diferencial não está na tecnologia isolada, e sim na capacidade de integrá-la ao conhecimento técnico para gerar decisões que economizam tempo e dinheiro....
OrcaFlex, digital twins & AI-assisted workflows
At NSG, OrcaFlex, digital twins and artificial intelligence are already part of the offshore engineering routine. But the difference isn't in the technology on its own — it's in the ability to combine it with technical knowledge to make reliable decisions that save...
From the rigor of oil and gas to offshore wind energy
The long-term performance of an offshore wind farm is determined long before the first turbine begins operation. Structural performance throughout a 20- to 30-year design life depends on a series of early-stage engineering decisions, including environmental load...
