Core Responsibilities

Primary Functions

Select, tie, dress, and set a comprehensive range of functional knots, bends, and hitches appropriate for specific materials, loads, and environmental conditions.
Design, implement, and manage complex rope-based systems for lifting, lowering, hauling, and securing heavy or awkward loads.
Conduct critical load calculations, including determining vector forces, friction effects, and safety factors for all rigging and rope system setups.
Perform rigorous pre-use and periodic inspections of all ropes, lines, cables, and associated hardware (e.g., carabiners, pulleys, shackles), documenting wear, damage, or degradation.
Execute advanced rope-work techniques, including splicing of natural and synthetic fibers to create custom-length lines, eyes, and slings.
Serve as the subject matter expert on-site for all activities involving knots and rope systems, providing direct oversight and guidance during critical operations.
Develop and implement site-specific rigging plans and rescue plans for work-at-height or in confined spaces.
Operate and maintain mechanical advantage systems (e.g., block and tackle, capstan winches) for efficient load management.
Ensure all rope work and rigging activities strictly adhere to industry standards and regulations (e.g., OSHA, ANSI, Cordage Institute).
Analyze system failures or near-misses involving rope work to identify root causes and implement corrective actions to prevent recurrence.
Fabricate and repair specialized rope-based equipment, such as nets, ladders, and safety lanyards.
Manage the inventory, storage, and life-cycle of all ropes and cordage, ensuring proper cleaning, drying, and protection from environmental damage.
Assess environmental factors such as wind, rain, and temperature, and adjust rope system configurations and safety margins accordingly.
Lead teams in high-angle or specialized rescue scenarios, applying advanced knot-craft to safely access and extricate individuals.
Provide clear, concise hand and voice signals to crane operators, winch operators, and ground crews during complex lifting and moving operations.

Secondary Functions

Mentor and train apprentices and junior team members on fundamental and advanced knot-tying and safety principles.
Develop and maintain comprehensive documentation, including rigging plans, inspection logs, and equipment retirement records.
Research and evaluate new materials, equipment, and techniques in the field of rope technology to drive continuous improvement.
Liaise with project managers, engineers, and safety officers to ensure rope-based solutions are integrated effectively and safely into broader operational plans.
Participate in job hazard analyses (JHAs) and pre-task safety briefings, specifically addressing risks associated with rigging and rope work.
Contribute to the development of organizational best practices and standard operating procedures (SOPs) for knot and rope applications.
Provide expert consultation during the planning and design phase of projects to ensure feasibility and safety of proposed rigging methods.
Manage communication across teams during complex multi-point rigging operations to ensure synchronized and safe execution.

Required Skills & Competencies

Hard Skills (Technical)

Expert Knot Craft: Demonstrable mastery of tying, dressing, and setting hundreds of knots, bends, and hitches for various applications (e.g., binding, load-bearing, rescue).
