Core Responsibilities

Primary Functions

Precisely tie, dress, and set a wide variety of knots (e.g., bowline, figure-eight, clove hitch, constrictor, rolling hitch) to meet load, security, and reusability requirements for maritime, theatrical, industrial, and rescue applications.
Perform professional splice work including eye splices, short splices, long splices, and brummel splices on natural fiber, synthetic fiber (nylon, polyester, Dyneema/HPPE), and braided ropes to manufacture custom rope assemblies.
Construct and assemble complex rigging systems, temporary lines, and standing rigging for ships, stages, cranes, and event installations, ensuring correct angles, tail lengths, and load distribution.
Inspect rope, hardware, and rigging assemblies for wear, UV degradation, abrasion, heat damage, and chemical contamination; document findings and make recommendations for repair or retirement based on industry standards.
Repair and maintain rope inventory by performing stitch repairs, whipping, heat-sealing, and re-splicing, ensuring all repairs restore rated strength and conform to manufacturer or regulatory guidelines.
Measure, cut, and finish rope ends to precise tolerances; apply whipping, back-splicing, or heat fusion to prevent fraying and to meet aesthetic and safety specifications.
Interpret technical drawings, load charts, and rigging plans to determine knot types, splice configurations, and hardware requirements for installations and lifts.
Select appropriate rope fiber, diameter, construction, and hardware (shackles, thimbles, eye bolts, winches) to achieve required safety factors and working loads.
Collaborate with engineers, riggers, and project managers to perform risk assessments, plan lifts, and ensure knot and splice choices align with site-specific safety and regulatory requirements.
Conduct static and dynamic testing of rope assemblies and sample splices when required; record test results and adjust manufacturing processes to meet quality control standards.
Maintain accurate records of rope life cycles, service logs, inspection dates, and repair histories to support traceability and compliance with maritime or industrial regulations.
Provide on-site support during launches, lifts, rescues, or theatrical set changes, adapting knot and rigging solutions quickly to changing field conditions while maintaining safety protocols.
Train junior staff, apprentices, or volunteers on knot selection, proper tying techniques, splice construction, and safety best practices to build a consistent skill base across the team.
Calibrate and maintain hand tools and small power tools used in rope finishing and splice preparation, including fid tools, splicing needles, sewing machines for rope, and heat-fusing equipment.
Prepare and package custom rope products and rigging kits to client specifications, including labeling with load ratings, material composition, and inspection intervals for professional distribution.
Advise customers or internal stakeholders on rope care, storage, and handling practices to maximize service life and maintain certified load-bearing capacities.
Develop and update standard operating procedures (SOPs) for knotting, splicing, and rope inspection that reflect industry best practices and regulatory changes.
Apply corrosion control and preventive maintenance techniques to metal rigging components that interface with ropes, ensuring compatibility and longevity of assemblies.
Coordinate inventory management: track rope stock levels, reorder critical materials, and evaluate supplier quality to maintain uninterrupted production and field operations.
Respond to non-routine technical problems by diagnosing causes of rope failure, documenting root-cause analyses, and implementing corrective actions to prevent recurrence.
Support custom fabrication requests by prototyping new splice types, specialty terminations, or bespoke knot-and-hardware assemblies for unique client requirements.
Ensure compliance with OSHA, IMCA, IRATA, ANSI, or applicable local maritime and industrial safety standards when performing rigging and knot-tying operations.
Prepare job-cost estimates and time-labor forecasts for quote requests related to knot-tying, splicing, and custom rigging manufacture, working with sales and operations teams.
Participate in post-job debriefs to capture lessons learned, recommend process improvements, and refine knot/splice procedures to enhance efficiency and safety.

Secondary Functions

Provide occasional field consulting for vendors and customers on best knotting and rigging practices, including advising on product selection and end-use limitations.
Assist in the development of training materials, how-to videos, and step-by-step guides to standardize knotting techniques across locations and remote teams.
Support inventory audits, labeling, and digital tracking of rope batches by material lot and manufacture date to assist warranty and regulatory claims.
Contribute to continuous improvement initiatives aimed at reducing waste, optimizing material usage, and speeding splice cycle times without sacrificing quality.
Participate in cross-functional safety committees and incident investigation teams to promote a culture of safety and continuous learning.

Required Skills & Competencies

Hard Skills (Technical)

Expert knowledge of at least 40+ knots and their practical applications across maritime, rescue, theatrical, and industrial use cases.
