Dans le monde exigeant du forage pétrolier et gazier, le terme "monosouris" peut paraître étrange, mais il décrit un rôle vital joué par un membre hautement qualifié de l'équipe de forage : le dérickman. Ce surnom, bien qu'utilisé souvent de manière légère, met en lumière la nature exigeante et physiquement difficile du travail du dérickman.
En Haut dans les Airs, Manipulant du Métal Lourd
Lorsque des tuyaux ou des tubages sont introduits ou retirés du puits, le dérickman est responsable de la manipulation de l'extrémité supérieure des tuyaux, atteignant souvent des hauteurs de 27 mètres ou plus dans le derrick ou le mât. Cette plateforme précaire, construite en acier et étayée par des câbles, devient leur espace de travail temporaire.
Un Équilibre entre Force et Compétence
Le travail du dérickman est un délicat équilibre entre force et précision. Il doit :
La Plateforme du Derrickman : Un Espace de Travail Unique
L'espace de travail du dérickman est aussi unique que son rôle. Ils travaillent sur une plateforme suspendue haut au-dessus du plancher du chantier, avec seulement une étroite passerelle la reliant au pont principal. Cette plateforme, généralement construite en acier et en grillage, offre un environnement de travail précaire avec un espace limité et une exposition constante aux éléments.
La Sécurité est Primordiale
Travailler à de telles hauteurs, manipuler des équipements lourds et être exposé à des conditions potentiellement dangereuses exige un haut niveau de conscience de la sécurité. Des protocoles de sécurité rigoureux sont en place, notamment :
Le Monosouris : Plus Qu'un Simple Titre
Si le terme "monosouris" peut être léger, il reflète les défis et les risques réels associés au travail du dérickman. Il faut un individu spécial, doté de force, de dextérité et d'une concentration inébranlable, pour assumer ce rôle crucial. Leurs compétences et leur engagement sont essentiels au fonctionnement sûr et efficace des plates-formes de forage, ce qui fait d'eux des acteurs véritablement vitaux dans l'industrie pétrolière et gazière.

Scenario: A derrickhand is preparing to run a new section of pipe into the wellbore. The pipe is 40 feet long and weighs 2000 pounds. The derrickhand needs to lift the pipe from the ground, move it to the derrick, and then guide it into the wellhead.
Task: Describe the steps the derrickhand would take to safely complete this task. Be sure to include the equipment they would use and the safety measures they would follow.
Here is a possible solution:
Here's a breakdown of the monkeyboard role (derrickhand) in drilling and well completion, separated into chapters:
Chapter 1: Techniques
The derrickhand's work involves a complex interplay of manual dexterity, strength, and precise technique. Key techniques include:
Pipe Handling: This involves using various tools like tongs, elevators, and hooks to grip, lift, and maneuver drill pipe, casing, and tubing. Techniques vary depending on the pipe's size, weight, and the phase of operation (running in or pulling out). Proper gripping techniques are crucial to prevent slips and accidents. The derrickhand must understand the weight and balance of the pipe to prevent dropping or swinging it.
Rigging and Unrigging: The derrickhand plays a crucial role in the rigging and unrigging of the drilling equipment. This includes setting up and dismantling the crown block, traveling block, and other components of the hoisting system. Proficiency in knot-tying and safe rigging practices are paramount to ensure the stability and safety of the equipment.
Communication and Signaling: Clear and concise communication is essential. The derrickhand works closely with the driller and other crew members, using hand signals and verbal communication to coordinate movements and ensure the safe handling of the pipe. Understanding and using standardized signals is critical for preventing miscommunication and accidents.
Emergency Procedures: The derrickhand must be proficient in emergency procedures, including responding to equipment malfunctions, pipe sticking, and personnel accidents. This includes knowledge of emergency shutdown procedures and rescue techniques.
Chapter 2: Models & Equipment
While the basic function of the derrickhand remains constant, the specific equipment and working environment vary depending on the type of rig.
Derrick vs. Mast: Derrickhands work either on a derrick (a tall, braced structure) or a mast (a simpler, often taller structure). The techniques and safety procedures may vary slightly based on the structure.
Hoisting Systems: The derrickhand interacts with the crown block, traveling block, and various sheaves and lines that constitute the hoisting system. Understanding the mechanical advantage and limitations of these systems is vital.
Tongs and Elevators: These tools are the derrickhand's primary means of gripping and manipulating the pipe. Different types of tongs and elevators are used for different pipe sizes and operations.
Safety Equipment: Essential equipment includes safety harnesses, lanyards, fall arrest systems, and appropriate personal protective equipment (PPE) such as hard hats, safety glasses, and gloves.
Chapter 3: Software and Technology
While traditionally a manual role, technology is increasingly impacting the derrickhand's work.
Rig Monitoring Systems: Real-time monitoring systems can provide data on the weight, speed, and position of the pipe, assisting the derrickhand in maintaining control.
Automated Systems: Some rigs are incorporating automated systems for pipe handling, though human oversight and intervention remain essential.
Training Simulators: Virtual reality and simulation training can enhance the derrickhand's skills and knowledge in a safe environment.
Chapter 4: Best Practices and Safety
Safety is paramount in the derrickhand's role. Best practices include:
Rigorous Training: Extensive training is crucial, covering both theoretical knowledge and practical skills. This includes competency in equipment operation, safety procedures, and emergency response.
Regular Inspections: Frequent inspections of equipment, rigging, and the derrickhand's platform are essential to identify and address potential hazards.
Communication Protocols: Clear and consistent communication protocols between the derrickhand and other crew members are essential to prevent accidents.
Pre-Job Planning: Detailed planning and risk assessments should be conducted before every operation to anticipate and mitigate potential hazards.
Emergency Response Plans: Well-defined emergency response plans must be in place and regularly practiced to ensure efficient response to accidents or equipment failures.
Chapter 5: Case Studies
This section would include real-world examples of successful operations, near-miss incidents, and accidents involving derrickhands, highlighting best practices and areas for improvement. Specific examples could analyze situations involving equipment failure, human error, and effective emergency response. These case studies would illustrate the importance of training, safety protocols, and risk management in minimizing hazards and ensuring the safety of the derrickhand and the entire drilling crew. (Note: Due to the sensitivity of safety incidents, actual case studies would need to be sourced ethically and with appropriate anonymization.)
