909 Offshore Oil and Gas Safety II

Tool Safety

Tool safety is critical on offshore rigs due to the inherent dangers of the environment, including high-pressure systems, heavy loads, and exposure to harsh conditions that can lead to catastrophic incidents if not managed properly. For instance, inspection and maintenance prevent premature equipment failure from vibration and stress, which could result in struck-by incidents or falls.

Without daily checks, issues like broken wires in hoisting lines (limited to no more than six randomly distributed breaks per lay length) can cause load drops, endangering lives. LOTO procedures are vital to isolate energy sources, reducing risks of caught-in hazards during repairs.

Proper handling emphasizes training and guards to avoid contact with moving parts, which account for many pinch-point injuries. Ergonomic designs, like handles on slips, minimize back strains and fatigue, especially in repetitive tasks like pipe handling. Storage and workspace management address slips and trips, common on congested, slippery rig floors exacerbated by oil and hoses—keeping areas clean directly lowers these risks.

Examples of Tool Safety

• Safety Clamps and Handles: On flush joint tubulars, safety clamps prevent tools from dropping into the wellbore. Ergonomic safety handles on slips, tongs, and mud buckets protect hands from pinch points during pipe connections, reducing smashed fingers and improving grip on slippery surfaces.
• Tong Die Drivers and Power Tongs: These tools allow safe removal and replacement of tong dies without finger injuries. Power tongs must include functional safety devices like relief valves to prevent over-pressurization, and they should be inspected and greased before each use.
• Hydraulic Slip Lifters: Used to lift slips pneumatically or hydraulically from a control panel, these reduce manual handling risks, preventing back injuries and errors from fatigue during repetitive operations.
• Wire Rope Maintenance: Regular inspections ensure removal if damage exceeds thresholds (e.g., three broken wires in one lay for standing ropes), preventing failures in hoisting operations that could lead to falling equipment.
• PPE in Maintenance: During tasks like cutting drilling lines, workers wear gloves and eye protection to avoid cuts from wire strands or flying metal chips, combined with securing lines before cutting.
