Supplied Fifteen New Engines for Soil Sampling Drilling Rigs

QuantiServ, as the exclusive dealer for Deutz high-speed engines and spare parts in Hong Kong, has sold 15 new engines to Hong Kong’s premier construction company. The engines will be installed in soil sampling drilling rigs.

The first five drilling rigs were completed at the end of 2017 and have been taken into commercial use already. The next batch of three will follow in March 2018.

The engines have a nominal output of 58kW at 2300 rpm and a maximum torque of 273 Nm at 1500 rpm. They are compact, light weight and are thus very popular in agriculture, mining and construction machinery all over the world. They are Tier III compliant.

Our scope of supply consists of the following:

  • Engines, type Deutz D914 L04
  • Control systems
  • Installation of the engines and control systems into the newly fabricated drilling rigs
  • Commissioning and site testing

QuantiServ have a long-term and good cooperation with many newbuilding and repair shipyards.

Recently QuantiServ were requested to carry out in-situ machining (line boring) of a rudder stem housing on a new type of LNG carrier that is under construction in a Chinese shipyard. Our team were on-board to calibrate the inner diameter of the rudder stem housing and found that the ovality and parallelism were out of limit.

Thereafter, a laser alignment check of the rudder stem housing was done and the corrections to be made were calculated. Finally in-situ line boring of the rudder stem housing was carried out successfully.

A final check showed that the ovality, parallelism, roughness and centre line of the rudder stem housing were all within tolerance. The shipyard was very satisfied with our service and confirmed the final result.
