5. DROPS SURVEY AND INSPECTION Independent Inspections or DROPS Surveys are conducted by Third Party Inspection specialists prior to start up of operations and every three years thereafter (sometimes annually as the Company requires). Planned Inspections or Systematic Inspections are undertaken by suitably qualified asset personnel and are scheduled: During equipment installation and following commissioning During and following major modifications or maintenance As recommended by OEM or Subject Matter Expert

6. DROPS SURVEY AND INSPECTION Unplanned or Ad Hoc Inspections follow the same process but typically follow unplanned events such as dropped object incidents, collisions, overloading or bad weather. These may also follow any operations that subjected structure and equipment to severe vibration and loadings. More frequent inspections and checklists are required to focus on specific components such as checking for loosening, wear or missing components.

7. DROPS SURVEY AND INSPECTION Separate Larger Facilities/ Structures into Manageable Areas and Zones Describe and Photograph each item Inspect and document fastening method(s) Record condition Conduct Risk Analysis Generate inspection criteria and frequency Area 1: Crown and Water table Area 2: Underside Crown to Fingerboard Area 3: Drilling / Travelling Equipment Area 4: Drill Floor to Fingerboard Area 5: Substructure / Moonpool / BOP Deck

26. RELIABLE SECURING PRINCIPLES: PRIMARY FIXINGS Confirm Primary Fixing method ( ie clamping, bolting, pin, turnbuckle etc ) is appropriate and as per OEM recommendations. Consider materials, tensions, tolerances as per Bill of Materials. Consider the effect of vibration or other dynamic forces that could cause disengagement.

27. RELIABLE SECURING PRINCIPLES: SECONDARY RETENTION Confirm Secondary Retention device ( ie lock washer, tab washer, lock nut, cotter pin, lock wire etc ) is installed correctly as per OEM recommendations. Consider how these devices lock in the tension on a bolted connection, prevent movement or reduce the effects of vibration. There are primary fixing methods (such as some beam clamp designs that do not feature any secondary retention.

43. TOOLBOX TALK CARD LOCATION TO BE COMPLETED AND RETAINED FOR EVERY JOB, NO MATTER HOW SMALL OR ROUTINE. DATE TIME JOB TO BE PERFORMED SUPERVISOR OTHER / THIRD PARTIES INVOLVED SAFE SYSTEMS OF WORK REQUIRED? (Tick) □ PERMIT □ ISOLATION □ SOP □ JSA □ LIFT PLAN WHAT TOOLS AND EQUIPMENT ARE NEEDED? Ensure you discuss Tools and Equipment to be used at height. WORK PARTY AGREEMENT Before starting the job, all members of the work party must sign below, agreeing that they fully understand the hazards and the risks associated with this task, and understand their duties and responsibilities in ensuring the job is completed safely and effectively. ________________ ________________ ________________ ________________ ________________ ________________ ________________ ________________ ________________ ________________ ________________ ________________ ________________ ________________ ________________ ________________ All persons joining the task must sign below. I agree to STOP THE JOB if the plan changes of if any new hazards become apparent. TOOLBOX TALK HIINTS AND TASK RISK IDENTIFICATION WHAT could hurt you or your colleagues? WHICH hazards did we find at the worksite? WHERE were they and how could the affect us? HOW will we reduce the likelihood of an incident? HOW will we reduce any consequences? HOW will we inspect our tools and equipment? WHO is going to manage these risks? WHO has been assigned specific tasks? HOW will we communicate with each other? WHEN will we plan for a Time Out for Safety? WHAT other activities are happening around our worksite? WORKSITE HAZARDS All of these hazards are likely to be present in every worksite and every task. Take time to identify each of these and discuss how to reduce the associated risk. MOTION. The change in position of items. Vehicles, vessels, water, wind, people, cranes, lifting, mechanical equipment, collision, snagging. GRAVITY. The force attracting items to the ground. Dropped objects, dropped tools, falling items, collapses, toppling, people tripping or falling. PRESSURE. Compressed energy or vacuum. Piping, cylinders, tanks, cans, gas and hydraulic hoses, vessels, tanks, pneumatic equipment. ELECTRICAL. Presence of an electrical charge. Power lines, transformers, static charges, energized equipment, wiring and batteries. FLAMMABLE. Combustible fuel sources. Petrol, diesel, oils, lubricants, sprays, vapours, oxygen-deficient atmospheres, welding, wood, paper. TOXICS. Chemicals and harmful substances. H2S, reactive hazards, paints, oils, radioactive sources, process fluids and chemicals. TEMPERATURE. Hot, Cold and Extremes. Flames, ignition sources, expansion, contraction, friction, steam and general environment condition. SLIPS, TRIPS AND FALLS. Stairs, surfaces, hatches, gratings, guard rails, ladders, spaces, wet floors, spills, uneven surfaces. PEOPLE. The No.1 Hazard in Every Task! Knowledge, skills, competency, attitude, complacency, neglect, housekeeping, attitude, health, wellbeing. ANY OTHER? Look Up, Down and All Around. Other activities, ground disturbance, material under tension, traffic, helicopters, stacking and storage. Now review these overleaf and discuss appropriate worksite controls that will eliminate the hazard or reduce the risk.

46. ZONE MANAGEMENT ESTABLISHING RESTRICTED ACCESS ZONE ( eg . Red Zone, Drops Zone) NO ENTRY ZONE ( eg . NoGo Zone) An area in which a Dropped Object potential has been recognized. The area is identified within the operational permit-to-work and authorized entrants are limited to the personnel needed to perform the work. Area Authority ( eg . Driller) is responsible for authorizing access. Physical barricades and signage clearly identify the covered area and the specific risk of the zone. An area in which a Dropped Object potential has been recognized ( eg . where moving equipment is present, where personnel are working at heights) and personnel are not permitted while the hazard is present or active. These zones are identified in the permit-to-work, controlled to prevent unauthorized access, and differentiated from the Restricted Access Zones by barricades and signage.

47. RED ZONE POLICY RED ZONE ACCESS Strictly controlled access, approval required from Area Authority; Follow Warden instructions; Only persons required for the task; Minimise exposure, identify step back areas; Personnel aware of all moving machinery and other hazards; Appropriate plan in place for specific activities; No personnel may join a task without a Tool Box Talk.
