A container accessory 600 for a stack of shipping containers (108, Fig. 1) for the purposes of dampening vibrational movement. The accessory comprises a frame 602, a releasable lockable coupler (400, Fig. 4) designed to secure the frame to the stack of shipping containers and a vibration dampener 620 (or damper). The dampener comprises a moveable mass 622 and resiliently deformable connector 624 (preferably a spring) coupled between the frame and the mass. Preferably there may be two resiliently deformable connectors positioned either side of the mass. The mass may be on a guided rail 628 and/or have rollers (702, 704, Fig. 7). There may be more than one releasable lockable coupler, preferably one at each corner of the frame. The stiffness of resiliently deformable connector may be adjustable either by hand or a motor. The frame may also be elongated with the mass moving between the long sides of the frame. The moveable mass may be 1% - 2% of the total mass of the shipper container stack (about 800kg 6000kg) and have a natural frequency between 0.3Hz 1Hz.
