In this paper, a concept is presented for decreasing the response amplitude of fixed offshore platforms using a movable submerged tank. The idea is based on utilization of the tank’s buoyancy and inertia forces to reduce the responses of the platform. In this concept, a four-legged platform is investigated in which braces are removed in lower levels, and the movable submerged tank including sub...

In the present paper, the effectiveness of Tuned Liquid Damper (TLD) in controlling the dynamic responses of offshore jacket platforms under earthquake excitation is investigated. This type of dampers consisting of one or more fluid (generally water) containers can be installed on the platform’s deck. Hydrodynamic actions induced by the tilting of the water surface in the container act as...

In recent years, developments in unmanned aerial vehicles, lightweight on-board computers, and low-cost thermal imaging sensors offer a new opportunity for wildlife monitoring. In contrast with traditional methods now surveying endangered species to obtain population and location has become more cost-effective and least time-consuming. In this paper, a low-cost UAV-based remote sensing platform...
