QSSL is known for its services in the hydro-blasting industry locally as well as regionally. This division of our company has and still is a fruitful venture. In addition, other maintenance services are provided. We provide quality and expert services in the following areas:
WET - ABRASIVE BLASTING
This method of surface preparation and cleaning is perfect for highly flammable or explosive areas. It uses a combination of abrasive and water at high pressure to remove rust and paint. It is quite effective in cleaning welds to carry out Magnetic Particle Inspection on vessels and surface preparation on offshore platforms, vessels and storage tanks to repaint. Together with this a rust inhibitor is also applied to prevent the occurrence of rusting on newly blasted areas.
Slurry blasting is the ideal method for surface preparation of metal and even concrete in cases where dust creates an issue. This method uses abrasive with air and water to carry surface preparation or cleaning in which the water suppresses the dust that would normally be generated from sand – blasting and washes the surface being prepared. It has proven to be highly effective and suitable for the oil and gas industry where sparks generated from sand – blasting poses a risk or fire hazard and even in the area of MPI inspections carried out on welded joints and bridges
COLD – CUTTING OF STEEL
Cold – cutting of steel is popular in the oil and gas industry as it relates to removal of tank sections or demolishing of tanks and vessels, Quintana has built a reputation in this area as we are the first to have successfully removed a tank section using this method. Cold – cutting uses UHP (40kPSI) combined with a precision nozzle and abrasive to cut steel. Noting the high levels of risks involved in carrying out these jobs Quintana has trained, certified and experienced personnel together with inspected and certified equipment from third – party inspectors. We also provide Turtle Suits for all our blasters given that this is the only recommended safety measure for those who are directly involved with the blasting.
TANK AND VESSEL CLEANING
Cleaning is our business, Quintana has been in the business of tank and vessel cleaning for decades and we have done so quite efficiently and effectively for all our clients. Offshore we have done entry - less vessel cleaning using the technologies available to us in record time. Utilizing our vacuum trucks and water – jetting pumps Quintana has successfully carried out numerous tank cleaning jobs. In all cases we have maintained all safety requirements, training and rescue teams and equipment ensuring our employees return unharmed or uninjured.
Quintana has been pursuing vacuuming as an integral part of our diversification drive and have introduced to our fleet of equipment; tractor trucks together with hydraulically driven vacuum tankers and trucks which we have renting to some of the recognizable names in the area of bioremediation and also to some of our clients in the industry. Our tractor trucks and vacuum trailers have become quite popular on the roads of this country and are available in 50BBL’s and 80BBL’s together with our fleet of 130BBL’s and 150BBL’s vacuum tankers.
Hydraulically driven vacuums were installed which can vacuum down to approximately 28” Hg and discharge up to 30 PSI. Recognizing the industry trends moving towards spark/ ignition free work environment in the oil and gas processing facilities, QSSL chose hydraulic options for our vacuum trucks and tankers. Being a part of the industry for decades QSSL understands the importance of safety and quality and so we provide third-party certification for all our units, visual, function and operator certificates together with spill kits on our trucks and trailers.
Not only did we invest in vacuum trailers, we have also purchased a fleet of brand-new flatbed 40’ trailers with loading capacity of 40,000 kgs and 45’ – 85’ extendable trailers with 50,000 loading capacity to complement our existing fleet of trailers. Together with tractor trucks and trailers Quintana also provides rental of truck mounted cranes commonly known as hiab with lifting capacity up to 10T. At Quintana we understand the importance of safety and therefore we ensure our equipment are certified together with experienced and certified operators and banksmen.

In recognising the need for such a service in Trinidad and Tobago and the region as a whole, we have invested in state-of-the-art equipment to competently perform projects of this nature. This initiative has proven successful in the oil and gas sector but is not limited to and has immense advantages in the potable water supply and distribution areas as well. Quintana has since rose to the forefront in the region in providing HDPE Equipment and Certified Personnel.
