One or more longitudinal partition plates distributed discontinuously are arranged at the bottom of the liquid tank in the length direction of the ship, a plurality of sliding rails are arranged in the transverse direction, and the longitudinal partition plates are connected with the sliding rails to move in the width direction of the ship. The longitudinal partition plate is connected with the bulkhead through a spring and a damper. The stiffness coefficient of the spring and the damping coefficient of the damper can be adjusted in real time, parameters of the spring and the damper are adjusted according to the liquid carrying rate of the liquid tank and monitoring of external excitation, the actual first-order resonance frequency of liquid in the tank is made to be far away from the external excitation frequency, and resonance is prevented. Meanwhile, when the liquid in the tank sloshes, the energy of liquid sloshing can be absorbed and dissipated under the combined action of the longitudinal partition plate, the spring and the damper, so that the impact pressure borne by the whole wall face of the liquid tank is reduced, and the service life of the longitudinal partition plate is prolonged. Therefore, according to the scheme, the probability of safety accidents caused by sloshing of the liquid tank is reduced, and the ship traveling safety is guaranteed.

An amphibious platform vehicle-vessel to support and to move hydraulically operated and controlled earth-moving and lifting equipment, such as excavators and cranes, on solid ground, semi-solid or marshy ground, shallow water, and deeper water. The modular units can be transported to a worksite on separate trailers and assembled and reconfigured on site. Two compartmented pontoon units are mounted to an adaptive cross member that can accommodate different types of moving-lifting equipment through different mounting flanges, and to auxiliary cross members. Propulsion is provided through amphibious cleats on drive chains in chain tracks driven by dual-motor driving drums and over a tension-adjusting passive chain roller, surrounding a sealed pontoon shell internally reinforced with bulkhead partitions, beam shell-bottom stiffeners, and pressed-angle shell-bottom stiffeners. An extendable auxiliary float can be extended outward from each compartmented pontoon for increased stability in floating operations. Spud units having a chain-drive spud and a spud-driving mount unit with spud-mount wear strips are hydraulically raised and lowered by a spud-driver motor at the command of the equipment operator using a spud-control switch.

A cabin module for a commercial aircraft comprises a set of bulkheads defining a quadrant with an inboard wall and converging side walls. The module is sub-divided by a removable partition which splits the module into two passenger compartments. The quadrant shape of the module enables it to overlap an adjacent seat area, thereby using space between seat areas that is otherwise underutilised. In aparticular form the modules define a single central aisle which transitions from a pair of parallel aisles aft via a Y-shaped transition region.
