The “Everywhere” Hazard Dropped Object - IADC

1 The Everywhere HazardDropped Object IADC Conference 23-24 March 20112 Ensco Asia Pacific Rim APRHad53 Dropped Object Cases in 2009with a percentage of 21%of all UPEHad23 Dropped Object Cases in 2010 YTD with a percentage of all UPEALL Dropped Objects must be reported as High PotentialLevel 2 incidentas they could cause a major injuryDropped Object3 Summary of anticipated Dropped Object cases: Unsecured Objects fall from Derrick(Top drive parts, Dolly roller pins, Elevator parts, Bolts/nuts, Derrick Lights, Standpipe bolts, Drill string parts such as clamps) UnsecuredLifting Gearduring Crane Lifting operations Falling pieces of Scaffolding Falling objects from Persons Hands Broken straps of Nylon bagsthat used to lift protectorsDropped Object4 Summary of anticipated Dropped Object cases : Lifting Hook release Falling objects during Wire Line/Coil Tubing operations Unsecured objects fall from beneath rig floor to platform Unsecured objects/hoses fall into the sea Objects, Casing/Tubing string fall in the hole Blown off objectsdue to high winds/helicopter downdraft Falling of UnsecuredhelmetDropped ObjectAPRBU Standard Format Sept.

2 085 The Day Toolpusher delegated two tasks to the Assistant Driller,both of them wereto be performed in the second task was to remove a redundant safety clamp from apermanently installed cement hose which hangs in the Assistant Driller completed the first task Assistant Driller relocated himself in the Derrick andcommenced the removal of the redundant safety clamp, duringwhich time the clamp Dropped 35 coming to rest on the DrillFloor away from an unrelated work ObjectIncident Example:Eyewitness of clamp impact.

3 All potential energy from a Object initially at rest is transferred to kinetic energy when Dropped . 2. The only acceleration is due to the force of gravity, which is assumed to be constant and essentially at sea level. 3. All energy is assumed to be absorbed by the individual and the PPE. 4. A fatality is the result of the total force required to break both the hard hat as well as the cranium. 5. A DAFWC is the energy required to break a bone in the shoulder or top of the foot. 6. A medical treatment case is the energy necessary to cause a laceration requiring The energy levels less than that requiring medical treatment are assumed to fall into the first aid category at The Dropped Object is assumed to be blunt edged, and whereas shape might be assumed to be spherical, it really only makes a significant difference if the Object has a thin flat edge or is shaped like a The worker with a potential to be struck is 25 - 40 years of age, is a male and weighs approximately 80 CalculatorThis program is based on physical laws of how mass of an Object Dropped from a height from and the relationship to the energy/force affecting the human (ft)Mass (lb)Height (m)Mass (kg)

5 The hose stocking restraining device is not a certified lifting device and is designed to be used like a conventional whip check to prevent hoses from kicking or whipping in the event of an uncontrolled pressure Object14 Corrective Actions: Continuous Revision and Developmentof Dropped Object Check List by the most experience hands onboard the rig Accuracy and Commitment with Routine Inspection, always look for more inspection than what is listed and have a Wide and Deep Look Immediatespecial inspection/securingbefore and after Critical operations Frequent inspection of Critical equipment such as slipsDropped Object15 Dropped ObjectENSCO RIG 97 Dropped Object Inspection (Note: Write auditor's name in Colored box when sheet handed in to OIM)Month:June-08 ZONES for Dropped ObjectWk-1Wk-2Wk-3Wk-4Wk-5 Derrick Man A-Frame -Crown -Water TableShaju JohnMelwin Furtado1st-2nd Platform & MonkeyShaju JohnMelwin FurtadoZone 1 BoardAsst DrillerMonkey Board Level PlatformsShaju JohnMelwin FurtadoStabbing BoardShaju JohnMelwin FurtadoZone 2 Floor Hands Travelling EquipmentDerrick Manand Top DriveShaju JohnShaju JohnZone 3 Rig FloorShaju JohnShaju JohnZone 4 Asst DrillerFloor Hands SubstructureShaju JohnShaju JohnZone 5 Drill CrewUnder CantileverClifford FernandesShaju JohnZone 616 Corrective Actions.

6 Always inspect Lifting Gearbefore and after any Lifting operation Don t use uncertified tools/equipmentfor any Lifting operation (they must have the right color code) Always ensure all pad eyes and lifting beams are certifiedand have the rightcolor code Use the right hole coverand keep tools/parts away from the hole as practicalDropped Object17 Corrective Actions: Always secure Light objects and keep Good CommunicationsAdditional Corrective Actions: Include specific Dropped Object Listin everyWIto include the probable Dropped objects related/involved into the carried out operation Create Temporary Listto include Temporary Installations such as scaffoldingDropped Object18 Dropped Object19 Dropped Object20 Fortunately we have incurredNo Personnel Injuriescaused by these incidents As the large majority of theDropped Object events had an effective pre-jobRiskAssessmentsthat includedPA announcements/warningsandbarricaded areasbelow work activity.
