In operation the skid is used to increase handling capacity of an ROV. The skid can be set up in the following different configurations, variable buoyancy FLOT mount, tool tray and auxiliary tray. In the variable buoyancy FLOT mount configuration the trim of the ROV can be altered by filling the buoyancy tanks at the front of the skid with varying volumes of air. In this configuration the skid is fitted with two 12 litre (3 US gal) air cylinders which are rated for a max. working pressure (MWP) of 300 bar (4,350 psi). These tanks are used to fill the two buoyancy tanks at the front of the skid which are capable of producing up to 170 kg (375 lbs) of lift. The other two modes, tool tray and auxiliary tray allows additional equipment to be stored on the skid. This tray is then extended to allow the ROV manipulators to interface with the equipment.
