A system that can be assembled at a well drilling or other site for storing bulk material such as sand includes a plurality of storage bins configured as trailers, a skid that includes a lower conveyor, a bucket elevator and a top conveyor system. At the site, the bins and the elevator are vertically oriented and stood on the skid, resulting in discharge outlets on the bins becoming positioned over the lower conveyor. The top conveyor is installed on top of the bins. In operation, the elevator lifts the material and discharges it onto the top conveyor system. The top conveyor system discharges the material into the bins for storage. The stored material is controllably discharged from the discharge outlets of the bins onto the lower conveyor from which the material is conveyed to one end of the skid for transport to a new location or directly into a blender.

The container body may also include a plurality of compartments each with upper edges defining an upwardly facing opening. The upper edges can be positioned to engage an inner surface of the lid when the lid is in the closed position so that the lid closes off the compartments.

The invention discloses a testing device and a measuring and calculating method for the gas permeability of compact rock material. Under the condition that the gas pressure at two ends of a rock sample are controlled to be the same, a gas pressure pulse is applied to the lower surface of the rock sample by a gas pressure control panel. When gas penetrates through the rock sample and enters a known pressure air storage tank under the action of the pressure of the pulse, the gas permeability of the rock sample is calculated by recording the change of the pressure of the pulse with time. The testing device and the measuring and calculating method are applicable to the measurement of permeability of mediums with low permeability, such as the storage of underground petroleum and natural gas, the storage of CO2, the disposal of nuclear waste, the storage of shale gas and the like and the measurement and calculation of the permeability of other compact rock mediums. Materials the permeability of mediums is between around 10-24m2 can all be measured and calculated by the device system.

An offshore offloading system for hydrocarbon products from a storage station such as an LNG/FPSO to a shuttle vessel. The system includes a yoke mooring arrangement having a yoke and a connection assembly. One end of the yoke is selectively disconnectable to the shuttle vessel, while the other end of the yoke is rotatably connected to an end of the connection assembly which has its other end rotatably connected to a frame which extends from an end of the storage station. The yoke and connection assembly are arranged such that a transverse force in the lateral or y-direction moves the end of the yoke less than twice the movement of the yoke in response to an x-direction force.
