Spar platform at deep water region in Malaysian sea
International Journal of the Physical Sciences, 2011 Exploration of oil and gas resources has been accelerated towards deeper waters due to depletion of their reserve in shallow water depth. Malaysian sedimentary basins signpost the existence of these energy sources below its sea-bed. In deep sea depth, traditional fixed types of offshore structures to explore these resources have become incongruous and ...

Numerical Simulation of Wave Loading on a SPAR Platform [PDF]
, 2003 This paper describes a study of simulation of wave loading on a SPAR platform. The method used for the simulations is based on the Navier-Stokes equations, discretised using a finite volume method. The free-surface displacement is described by the VOF-method combined with a local height function.

A Versatile-Designable Framework for Active and Programmable Shape-Morphing Soft Matter Systems: From Inverse Design to Closed-Loop Control. [PDF]
Adv Sci (Weinh)A versatile framework integrates addressable electrothermal actuation and strain‐constraint mechanisms to construct programmable shape‐morphing soft matter systems. By combining an analytical inverse design strategy for high‐fidelity 3D surface reconstruction with deep learning‐based closed‐loop control, this approach enables zero‐energy shape locking,
