This project aims to develop a novel inerter-based damper to mitigate the excessive vibrations of offshore floating platforms (OFP), which are widely used in the offshore industry for oil exploration. Harsh environmental loads such as wind and waves can induce excessive vibrations to OFPs and endanger their safety and stability. This project aims to develop a novel inerter-based damper that can produce a considerable apparent mass that is much larger than its physical mass through an amplifying mechanism by translating the linear motion into high-speed rotational motion, which can significantly reduce the mass and cost of the damper. Benefits of the project include more economical and safer OFP designs, which are expected to improve the competitiveness of Australian pillar oil and gas industries.

该项目旨在开发一种新型的基于阻尼器的阻尼器，以减轻海上浮动平台（OFP）的过度振动，OFP广泛应用于海上石油勘探行业。恶劣的环境载荷（如风和浪）会引起ofp过大的振动，危及其安全性和稳定性。本项目旨在开发一种新型的基于干涉器的阻尼器，通过将直线运动转化为高速旋转运动的放大机构，可以产生远远大于其物理质量的相当大的表观质量，从而可以显着降低阻尼器的质量和成本。该项目的好处包括更经济、更安全的OFP设计，有望提高澳大利亚支柱石油和天然气行业的竞争力。
