Core Responsibilities

Primary Functions

Perform precision torqueing and tensioning of critical bolted connections on industrial equipment, such as wind turbines, pressure vessels, and structural steel, using hydraulic, pneumatic, and electronic tooling.
Interpret complex engineering drawings, blueprints, and technical specifications to determine fastener requirements, torque values, preload calculations, and assembly sequences.
Set up, calibrate, and operate a wide range of specialized bolting equipment, including hydraulic torque wrenches, bolt tensioners, pneumatic multipliers, and stud runners.
Conduct thorough pre-and post-job inspections of fasteners, threads, and joint surfaces to identify defects, corrosion, or damage that could compromise joint integrity.
Utilize ultrasonic measurement devices to accurately verify bolt stretch, load, and elongation, ensuring compliance with strict engineering and quality standards.
Execute fastener removal procedures, including nut splitting and stud extraction, for maintenance, repair, or replacement of components.
Maintain meticulous and accurate documentation of all bolting activities, including recording torque values, tensioning pressures, tool calibration data, and job completion reports.
Champion a safety-first culture by performing comprehensive Job Hazard Analyses (JHAs) and risk assessments before commencing any work.
Adhere strictly to all company and client-specific safety protocols, including Lock-Out/Tag-Out (LOTO), confined space entry, and working-at-heights procedures.
Perform regular function checks, maintenance, and minor repairs on all torqueing, tensioning, and associated hydraulic power-pack equipment to ensure operational readiness.
Identify and select the correct type, grade, and size of fasteners, gaskets, and lubricants for specific applications based on technical manuals and project requirements.
Assemble and disassemble complex mechanical components and flanged joints in a controlled and systematic manner to prevent misalignment or damage.
Troubleshoot and resolve common bolting issues in the field, such as galling, thread damage, or incorrect preload, and implement corrective actions.
Collaborate with engineers, project managers, and quality control personnel to ensure all work is performed to project specifications and industry standards (e.g., ASME, API).
Operate overhead cranes, hoists, and other lifting equipment to safely maneuver heavy components into position for assembly.
Maintain a clean, organized, and safe work environment, both in the workshop and at remote field locations.
Provide clear and concise status updates to supervisors regarding job progress, equipment issues, and any potential delays.
Work effectively both independently and as part of a larger maintenance or construction crew, often in adverse weather conditions and physically demanding environments.
Participate in ongoing safety training and technical certification programs to stay current with the latest industry best practices and technologies.
Manage and maintain the inventory of fasteners, spare parts, and consumables required for scheduled and unscheduled maintenance tasks.

Secondary Functions

Support ad-hoc maintenance requests and assist other trades on-site as required.
Contribute to the development and refinement of standard operating procedures (SOPs) for bolting and assembly tasks.
Assist in the training and mentoring of apprentice-level technicians on proper tool usage and safety protocols.
Participate in sprint planning and daily toolbox talks to align on project goals and safety topics.
