Company
profile
G-force, servicing the Marine (ships & ports) industry and the oilfield sectors of Drilling, Production and Refinery operations for the purposes of design, manufacture,
installation & operation of custom or standard build separation systems for treatment of oily
waste and slop oil.
G-force Oily Waste Separation Systems provide benefit to clients seeking an environmentally sound Waste Management Program. This is to comply with the standard practices of the Environmental 3R's - Reduce, Recycle, Re-use.
G-force treated oily waste is:
- Reduced (minimized) to solids by removal of liquids, and
- Recycling of Oil and Water, and
- Re-use of oil as a product with water returned to
nature.
 G-force therefore, sells, manufactures, installs and operates treatment systems required in the
Marine industry and the Oil & Gas Industry to clean oily waste generated as a by-product of their operations. These wastes are identified from drilling, production and completion fluids, operations fuel oils and diesel oils, produced water, crude oil refinery & transport vessels slops and sludges, refinery emulsions, API separator sludges, tank bottom sediments, stored oil waste pits, polluted soils,
ships slops, bildge water, dirty lube oils and the like.
G-force separation systems are either fixed or portable installations to be found on drilling
rigs, production facilities, crude oil gathering stations, crude oil
refineries, waste plants servicing land base and marine port reception
facilities, tank farms, oily waste dump sites and oil polluted soil sites.
The separation systems manufactured by
G-force come in standard skid modules or if required are manufactured to fit custom
applications. They are designed as ready to go fully integrated 
"plug-in" skid modules to minimizing installation time and
cost. The skid modules are manufactured to fit into standard 20' or 40' containers providing the most economical means of transport by either truck or sea
freight. Standard container packages allow for normal lifting equipment thereby greatly reducing handling cost and facilitate easy plant movement from site to site. Common equipment type and sizes of separation systems manufactured by
G-force vary with the application and waste source to be
treated. Below is a sampling of common waste by classification to different types of Oilfield
operations.
Drilling Fluids
These skids are manufactured in accordance to rig operator requirements and involve De-gassers, Shale Shakers, De-Sanders, De-Silters, Mud Cleaners, Cuttings Dryers, Decanter Centrifuges, Flocculation Units, and Drill Cuttings Conveyors. These are supplied in single units, in multiple units, or combinations thereof, which are fully incorporated and integrated into a functional skid for rig installation.
Oily Water
These skids are manufactured in accordance to water treatment requirements and
application. 
The system normally involves the incorporation of feed pumps, screen filters and high-speed 3 - phase centrifuges. In
general a single centrifuge for the treatment of oily water could range from 15 to 50
m³/hr per unit supplied. Greater capacity is achieved by multiples of units installed in tandem.
Oily Slops
These plants are manufactured in accordance to the definition of slops, which vary from diesel oil to crude oil, or in mixture of several types of oils. The system normally involves the incorporation of a heat supply, feed pumps, screen separators, (possibly) 2-phase decanters and high-speed 3-phase centrifuges. The 3-phase centrifuge is the piece that determines the plant capacity. In general a single centrifuge for the treatment of oily slops would range from 5 to 10 m³/hr per unit supplied. Greater capacity is achieved by multiples of units installed in tandem.
Oily Sludges
These plants are manufactured in accordance to the definition of sludge to be treated. Sludges vary widely in composition coming from all sources of oily waste streams. They can be single source sludges of crude oil tank bottom cleanings dumped and stored in a tank or an earth pit. Or they can be an endless combination of oily waste coming from all different sources - mixed, dumped and stored together awaiting treatment. Sludges are commonly inconsistent, contaminated with miscellaneous debris, are thick and viscous complicating their treatment, especially as they influence equipment thruput capacity. The sludge treatment system normally involves the incorporation of a heat supply, feed pumps, (possibly) bulk hoppers with conveyors, screen separators, 2-phase decanters and high-speed 3-phase centrifuges. In sludge treatment the final 3-phase centrifuge is the piece of equipment that determines the plant capacity. In general a single centrifuge for the treatment of sludges would range from 2½ to 7½ m³/hr per unit supplied. Greater capacity is achieved by multiples of units installed in tandem.
Polluted Oily Semi Solids
These
 plants are manufactured in accordance to the definition of oily materials to be
treated, which range from drill cuttings to polluted soils. These materials are generally earth solids with oily liquid retained on the solids
particles. Normally oily solids are not pumpable and are only considered for treatment in a
G-force separation system if the polluted solids are saturated with free liquids capable of being separated by
conveyor, screen separators and 2-phase decanters. The use of 3-phase centrifuges is applied only if the solids waste is washed creating liquid volumes needing separation from the wash water. This allows for the wash water to be
recycled. Tractor bucket, skips and conveyors generally handle the mobilization of these
materials.  The solids treatment system normally involves the incorporation of bulk hoppers with
conveyors, wash tanks, screen separators, 2-phase decanters and possibly high-speed 3-phase centrifuges. In general oily semi solids are treated more in line with residence time on or through the equipment employed and in this system the 2-phase decanter generally dictates the thruput
capacity. In general a single decanter for the treatment of fluidized semi solids would range from 2 to 4
m³/hr per unit supplied. Greater capacity is achieved by multiples of units installed in tandem.
 Organization
G-force was established through an organizational change in 2000 made by
Alfa Laval going from a privately held firm (after 122 years in
business) to a public holding company.
This led to the closure of Alfa Laval’s Oilfield Division and
resulted in the set up of G-force as an Alfa Laval OEM (Original
Equipment Manufacturer) for the purpose of fabricating full-scale oily
waste treatment plants using exclusively Alfa Laval’s Centrifuges and
Heat Exchangers. The Alfa
Laval exclusivity under the OEM was maintained for our first three years
of business.
In January 2004, to better serve our clients, G-force decided to become
an independent manufacture free to utilize any equivalent competitive
components to Alfa Laval’s equipment.
This new arrangement allows G-force to select the best technical
and commercial supply options available as separation components for use
in our manufacturing process and/or to provide any component
specifically requested by the Client. Also in 2004 G-force formed
an alliance with WRT BV a Dutch Manufacture of Treating Chemicals which
in many cases are vital to achieving treated materials specifications
associated with the separation of oily waste. For more information
about WRT BV please visit their WEB Site at www.wrtbv.com
We still offer the same equipment warranties and performance
guarantees as we did under Alfa Laval’s OEM Agreement.
G-force separation systems are manufactured in the Netherlands in
partnership with Tekoma BV (see www.tekoma.nl)
who has manufactured Alfa Laval modules for the past 30 years, the Alfa
Laval BV Service Center is also located at Tekoma.
Therefore certificates of origin and conformity to codes and
regulations are issued in accordance to Dutch and European Community
standards.
G-force is in compliance to ISO 9002 certification through our
partnership with Tekoma BV it being the workshop where our plants are
manufactured. G-force
separation systems are manufactured (if required by the Clients
specifications) to meet explosion proof regulations normally required
for equipment supplied to the Oilfield sectors.
