以人为本 People Oriented 健康安全 Health and Safety 科学管理Structured management 持续发展Continuous improvement

People Oriented: People is key to all good work. Our HSE policy follows the principle of focus on people with the objective of bringing out the initiative and innovation in all our staff in ensuring achievement of our HSE goals and effective implementation of our HSE procedures.

Health and Safety: Health and Safety is a common goal of the Company and our people. With our people healthy and working in safe environment, our people will display greater accomplishments in quality and technology thus contributing to the growth of the Company while realizing our unified HSE goal.

Structured Management: A structured and well organized management system is fundamental to moving the Company forward. In addition to compliance with regulations and other requirements, we will observe market trends and continuously move the Company towards higher HSE standards.

Continuous improvement: HSE is not only a business requirement, it is also a social responsibility. Through the successful implementation of our HSE system, there is greater control over safety risks and reduction of incidents/ accidents which demonstrate our continued commitment towards HSE.

HSE Policy


1. HSE accreditation - ISO14001 (Environment Management System) and ISO18001 (OSHAS)

2. Top Management Involvement in HSE – commitment well demonstrated in the HSE policy (emphasis on personal health and safety and extends to social responsibility)

3. Training program for all employees especially new recruits and internal transfers

4. Monthly safety safaris organised by HSE department involving senior managers from various departments including Quality, Production etc are carried out. The inspection team observes safety compliance generally by employees wearing protective equipment, workplace safety, hazards etc. NCRs are documented and reported to the General Manager. In addition, an annual internal audit is conducted by internal audit team and results of the internal audit are reported during management meeting chaired by the General Manager.

5. Performance indicators –

(a) Compliance with local regulations, NCR are 100% addressed

(b) Minor incident not more than 1 per month

(c) No major inquiry or loss of life

6. Environment protection - implement water recycle system to reduce water usage, waste are collected and handled according to environmental rules, especially chemicals.

Therefore, both connections will always be interchangeable


Design Review & Validation

DP-Master has received FEARNLEY PROCTER NS-1TM Level 3 Design Approval for our DPM-DS55 Double Shouldered rotary drilling connection for use on Drill pipe. The Level 3 review incorporated compatibility tests (make and break) with NKK DSTJ 5 ½ along with FEA review and witness of connection make and break.


• Designed as a high performance rotary shouldered connection

• Design evolved from original DPM-DS connection

• Geometry changes at critical areas and added mass for increased strength

• Retain API taper and thread form for operator friendliness and economy over the product life cycle

DP-Master has received FEARNLEY PROCTER NS-1TM Level 3 Design Approval for our DPM-MT39 Drill pipe connection.


FEA Fatigue Performance • Cyclic bending was simulated to identify critical

areas of fatigue on connection located at the last engaged thread root of the pin & box ends

DPM performs cold roll operation on all DPM-MT connections

Cold Rolling of the thread roots and flanks induces a compressive layer which reduces susceptibility to cracking thus enhancing fatigue resistance

Box Counterbore at 0.006'' Gap

Pin Nose at 0.006'' Gap

Two axial gaps were chosen (0.002” and 0.006”) and secondary make-up was simulated. When made up, the connections are in compression thus the negative axial stress. At both axial gaps, the pin nose and box counterbore maximum axial stress is below the MYS of 130 ksi. Thus they do not yield at MUT.

FEA to find Secondary Make-up Shoulder Optimum Axial Gap • Initiate pin nose contact with make-up shoulder at MUT which

contributes to added torsional strength

• Eliminate undesirable downhole make-up

• Pin nose induced stress does not exceed MYS (130 ksi) causing plastic deformation in the pin nose


Torsional Test, Torque to Yield • Calculated yield is verified by torque to yield on sample connections

• Apparent yield is comparable to calculated yield


DPM-MT39 Calculated Yield - 33,000 ft.lbf Apparent Yield - 34,500 ft.lbf





Post Torque to Yield Inspection • Tool joints are durable

• All tested connections remain intact even when subjected to torque values beyond torsional limit

DPM-MT39 after being made-up to 40,293 ft.lbf. Note the increased diameter of the pin nose due to applied torque-stop compressive stress.

MT-57 Sample 3 after being made-up to 93,137 ft.lbf, beyond yield point without perceptible box swelling Arrow is pointing to a ridge or “fin” around the perimeter of the primary torque shoulder. This Fin is caused by compressive yielding of shoulder.
