SN.SEQUENCE OF BASIC STEPSHAZARDS AND (PERSONS AT RISK)POTENTIAL HARMEVALUATION OF RISKCONTROL MEASURES

SLRRISK LEVELPROBABILITY

1.Securing T-bar on cableGravitational Potential Energy (Stepping, Handling, Lifting)Cable slip through T-bar. High tension on cable endanger personal.

Personnel Injury428HUnlikely - Certified winch operator

- Tension on cable to be increase gradually

- Set T-bar down on rotary table several times to ensure cable not slip

- During testing of quick connects, all personnel away from rig floor. Be aware of T-bar that might spin wildly

- Wearing PPE

- Exclude non essential personnel to work around the area

2.Rig up/down upper sheave wheel at crownGravitational Potential Energy (Stepping, Handling, Lifting)

Lifting of personnel with weight and sheave wheel at high height. Risking falling down of personnel and equipment. Get caught in moving sheave wheel.

Personnel Injury Assets Damage6212HUnlikely - Toolbox meeting prior to operation

- Usage of certified lifting gear and safety harness

- Usage of safety pins securing personnel and equipments shackles.

- Certified air tugger operator

- Avoid sudden jerk or stop while lifting up personnel

- Third watchman to provide signal & instruction

- Radio communication between watchman and up-lifting personnel

- Exclude all personnel working underneath

- Operation to be conducted slowly

- Adequate cables been spooled on rig floor before personnel lifting

- Wearing PPE

3.RIH/ POOH cableGravitational Potential Energy (Stepping, Handling, Lifting)

Personnel are exposed to high movement of cable during operation. Pinch point injuries while latching and unlatching of spearhead and overshot. Cable or weight catches on top drive, thus breaking cable or swivel. Getting hit by moving drill pipe.

Personnel InjuryAssets Damage4416HMay Happen- Toolbox meeting prior to operation

- Ensure no-go hardware is used and fishing assembly are check

- Great coordination between rig floor and winch operator

- Mark cable to assist winch operator controlling winch speed

- Wearing PPE

- Establish Intercom system and backup radio communication between driller and winch operator

4.Breaking weakpoint with top driveGravitational Potential Energy (Stepping, Handling, Lifting)

High tension on cable. Potential injuries to personnel

Personnel Injury 4416HMay Happen - Never exceed safe working load for cable

- Increase cable tension gradually

- Make announcement prior to operation

- Exclude all personnel around working area
