The Dual Fuse, Off-Shore, closed loop, integrated drilling waste management system comprises a series of auxiliary, interdependent equipment, with the Dual Fuse container at its center, collectively creating the much desired perfect harmony much like a well-rehearsed and attuned philharmonic orchestra. The Dual Fuse Shaker can be found upstream on the Oil Rig and is used to collect drill cuttings above 75 μm brought from the drilling well via a feeder.

The Pulse Air system is hooked up to the DFT containers via a fixed flexible hose manifold to a ‘Blow Valve’ controlled by pneumatic timers in the Pulse Air Panel. The air supply to the Pulse Panel is taken from the Conveying Air pressure regulator on the PRU via 8mm tubing. From the panel, 8mm tubing is used for Control air to the Burkert Blow Valve on the pulse hose. Air to the Pulse Air Panel is supplied from the Pressure Regulator Unit (PRU) ‘Top Air ‘(Tank air). Each individual Air Pulse injection has a flow restriction device to regulate the flow to 2m3/m at 6barg. The Pneumatic timers are set to give a cycle of six seconds with ‘1 second air on’ and 5 seconds air off.

One feature that sets it apart from regular iso tank containers is that the DFT containers, can be operated when placed in the common horizontal plane as well as the vertical plane, not unlike a silo. When standing vertically on its rear end frame, the DFT container does indeed resemble a silo if only you look at its conical bottom section. This vertical configuration and it's resulting small footprint is favoured on Offshore Oil Rigs where space is tight. Dual means 'consisting of two parts.' In practical terms what it means here is that 'Dual' relates to it affording Operators twice the regular common tank functionality i.e. a capacity to load under vacuum plus additionally the capacity to load & discharge through positive air pressure. Besides the design of the DFT container, what gives it its power is the equipment it gets 'hooked up to,' to load and discharge. This includes heavy-duty liquid ring vacuum pumps with air capacity of 1600cfm, Liquid Ring Vacuum Pump, ATEX certified T-5, belt-driven, 27" Hg Vacuum. As for pneumatic operation Modular 1000 cfm (150 psi) Zone ll DNV 2.7-1 Air Compressors have to be deployed.

On Oil Rigs Air is commonly used for the conveyance of drilling waste via blowers into skips, vacuum boxes but increasingly into ISO tank containers designed and certified DNV 2.7.1 EN12079 for Offshore use, ISO tank containers that can be operated whilst standing in the vertical plane. Pressurized service air can be obtained from the Rig itself or more commonly from one or more Air Compressors. The Air compressors use Rig air to start up. The Compressors are stacked to minimise deck space and are secured with iso container twist-locks. There are also heavy angle sections welded at each corner of the lower Compressor to secure them in place. Service air is piped to a 2” Distribution Manifold from where air is supplied to the Cuttings Blowers and via the PRU to the DIM (DFT Installation Module) located at the foot of each of the DFT containers.

@ Dual Fuse, we are perpetually fascinated by the power that we manage to bring to bear with air, both in positive and negative pressure ranges. The outcome of our fascination with air +/- radiates through the vast majority of our products up and downstream from the Rig drilling operation especially in our Dual Fuse-Cuttings Blowers. The Cuttings Blowers are located upstream on the Rig from where the Shakers transfer drill cuttings direct via a hopper or via screw conveyors into the Cuttings Blowers.
- Self-contained compact design that seamlessly interface across pneumatic and electronic technology
- Closed system
- High Service reliability
- ATEX certified to operate in hazardous-zones
- Pneumatically operated

Dual Fuse® operation is supported by essential auxiliary equipment:
Weigh Frame
The Weigh Frame designed according to ISO standard 668, is a framework designed to support the Dual Fuse® container when it stands in the vertical plane and comes complete with removable load cell and a 12” Dial. The Dual Fuse® is locked onto the Weigh Frame via its corner castings and the Iso twist locks incorporated into the Weigh Frame design.Rig Installation Module
The DNV 2.7.3 certified, Dual Fuse® Rig Installation Module (DIM) (also referred to as ‘RIM’ (Rig Installation Module) or Rig Piping Interface Module) is a purpose designed module that is transported to Rigs where it is placed at the foot of each Dual Fuse® container. The DIM or otherwise called RIM module is effectively a piping manifold assembly complete with walkway grating and handrails for added operational safety that brings together all pipes that are essential for the operation of the Dual Fuse tank container including material to be loaded, compressed air, control air. It is for this reason that a Dim is placed at the foot of each Dual Fuse tank container.
