DSS Safe Work Culture

DSS thrives to develop a safety culture for its employees through conducting: regular trainings, tool box talks, DSS safety induction, Safety Observations and Corrective Actions (SOCA), a performance board that shows the productivity and safety trends. Safety and Production are inseparable, and every person is responsible and will be held accountable for both safety and production.

Fit For Purpose Equipment

DSS has put in place a set of its own self-driven safety standards for its equipment. This ensures that our staff are put at minimum risk when working with our equipment. This involves upgrading of the drilling rigs to meet industry safety standards.

DSS equipment is maintained to high standard by in-house teams utilizing OEM standard parts. Routine inspection of equipment ensures that onsite failures, that would risk employees safety and project delivery are minimized.

Our Portfolio

Our Equipment

Foremost DR-24 Dual Rotary Rig

The DR-24 will set casing up to 24” (610 mm) in diameter. This model is commonly used for domestic and municipal wells, and construction applications such as foundation piling projects and holes for hydraulic elevator jacks.


Foremost DR-24HD Dual Rotary Rig

The DR-24HD (‘heavy-duty’) features a heavy-duty gear-driven lower drive, which generates two and a half times the torque of the standard DR-24. The DR-24HD is also configured with a heavy-duty mast to withstand the additional torque and larger hoist cylinders for increased pullback capabilities. The DR-24HD is most commonly used in deep, large diameter applications such as municipal/industrial wells and mine de-watering.


Schramm T130 XD Dual Rotary

This mobile Heavy Hoist, Range 3 ready capable drill rig is suited to Deep Water Well and Oil and Gas Exploration and Development work. The machine is fitted with a 26” Casing rotator providing all the benefits of Dual Rotary drilling with Hands free Range 3 tubular handling.

The rig is ideal for Conductor Placement by driving and drilling and Top-hole work for surface casing.

The rig is also used for mineral exploration drilling and can be set up for reverse circulation. The rig is equipped with a telescoping mast and is mounted on a heavy carrier, which allows it to be moved easily on commercial roads without traffic disruption. We have equipped the rig with a hands free drill pipe and casing handling system to improve the safety of the crew on the drill site.


Schramm Loadsafe Tubular Handler

Loadsafe ® is true to its name, offering safe, hands free cycling of drill pipe, collars and well casing for all Schramm Telemast ® rigs designed with tilting top head drives. This automated system is fully intergrated into TXD rig rated at 200,000lb hoist, and is also offered as an option or retrofit for Schramm T200XD, T130XD and T90XD rigs used in energy, mineral exploration, mine rescue, large diameter municipal water well or deep hole geothermal drilling applications. Loadsafe ® is fed from hydraulically operated pipe racks set up in the horizontal position, eliminating "crow's nest" safety concerns fou nd in traditional vertical pipe handling systems. Drill pipe or Range 3 casing is lifted from rack position into alignment with the tilting top head of the rig. A hydraulic roughneck on the rig eliminates manual tongs and the typical risks associated with their use while tripping drill pipe.


KLR DTH 2000 and DTHR 450 Drill Rig

We operate 3 KLR Top drive rigs rated to 300m depths at 8” diameter. The rigs are mounted on 6x4 carriers with separate engines on the deck for the hydraulic functions. We can drill by DTH and direct rotary techniques as the situation requires. The rigs have been upgraded with safety railings, rotation guards and emergency shutdown switches.

DSS SIMBA MKI Drilling Rig

We manufacture drilling rigs uniquely suited to the conditions in rural areas. Our SIMBA series of drills are very light-weight and mobile but this is not achieved at the expense of power. The SIMBA MK1 and MK2 water well rigs are designed to be very simple to operate and maintain yet incorporate innovative feed and rotation concepts. The drill rigs are customized to the requirements of each customer and we provide on-site training for the users.
