The Seismic Response of Offshore Wind Turbines Supported by Monopiles and Alternative Foundations in Liquefiable Soils
… requirements of a maximum turbine tilt of 0.5° (DNV-ST-0126, 2021; DNV-RP-0585, 2021). However, the amount of average settlement and rotation experienced by monopiles may be affected by several factors. Among these, the monopile diameter, the magnitude of the operational loading, and the density …

FSI Methodology for Analyzing VIV on Subsea Pipeline Free Spans with Practical Boundary Conditions
… simulations; however, Det Norske Veritas (DNV – translation to The Norwegian Truth) Recommended Practice F105 states that these boundary conditions must adequately represent the pipe-soil interaction and the continuality of the pipeline. To adequately simulate the free span’s response to …

Structural fatigue assessment and optimisation of offshore wind turbine jacket foundations.
… employed, modelled in industrial software from DNV, and transformed into a super element model. The time-series loads obtained from Bladed are used to assess fatigue damages experienced during the foundation's service life. Furthermore, the research presents a topology optimisation method to …

Introduction of a Best Practice for Ventriculostomy Management in the Neuroscience Critical Care Unit
… 337 bed ACS Level 1 certified trauma center and DNV Level I certified stroke center in Scottsdale Arizona. SUBJECTS: Retrospective chart review (n=20) most recent patients who had a ventriculostomy drain placed in the neuroscience ICU. Average age 54.6 y/o ±17.8 and average LOS 15.45 days ±9.1. …

Cyclic behaviour of monopile foundations for offshore wind turbines in clay
… Results from monotonic tests suggest that the DNV (2014) design methodology to construct p-y curves in clay based on Matlock’s (1970) soft clay criterion significantly underestimate stiffness. Findings suggested that the experimental p-y curves could be characterised through modification of the …

Design of paired column semisubmersible hull
… with weather conditions as recommended by API, DNV, and ABS. The AQWA model was validated with results recorded by Imetrum system from the wave tank experimental test. The wave forces and moments were studied for different draft sizes and ocean conditions, and their response where checked in …

Hydrodynamic performance of multi-component structures in oscillatory flow, from blow-out preventer to dual Cylinder interference
… The current industrial standard suggested by DNV on the modelling of the BOP will be given. In order to re-evaluate the problem, the non-dimensional analysis will be carried out and the key hydrodynamic effect parameters of the KC number, [beta] number and the angle of attack [alpha] will be …

Computational fluid dynamics modelling of pipeline on-bottom stability.
… works (such as that carried out by Lyons and DNV) concluded that soil resistance should be determined by considering Coulombs friction based on lateral resistance and passive resistance due to pipeline embedment, but the significance of passive resistance in pipeline stability and its …

An introduction to geotechnical design of South African wind turbine gravity foundations
… according to theories suggested by the DNV/Risφ (2002) guidelines and site-specific bearing capacity theories. Settlement concerns were addressed through the analysis of immediate elastic settlement beneath a foundation using a general elastic solution, a non-linear stepwise method as …

Integrated Maritime Simulation Complex Management, Quality And Training Effectiveness From The Perspective Of Modeling And Simulation In The State Of Florida, USA (A Case Study)
Naturally, maritime training simulators at all events are valuable instructional and pedagogical tools. Through the history, the maritime simulation was utilized to train prospective maritime apprentices in whom it has filled the gap left by the acute shortage of opportunities for jobs onboard …
