Certification
Certification & governing bodies
- IRATA
- Industrial Rope Access Trade Association — the global governing body for industrial rope access. It sets training and safety standards and operates a three-level certification recognised in more than 70 countries.
- SPRAT
- Society of Professional Rope Access Technicians — the North American rope access certification body. Recognised mainly in the US and Canada; IRATA is the more widely accepted standard internationally.
- IRATA Level 1
- Entry-level rope access technician. Works under the supervision of a Level 3, performs basic manoeuvres and assists with rigging. Requires a 4–5 day course and an independent assessment; no prior experience needed.
- IRATA Level 2
- Experienced rope access technician who can rig and de-rig, perform advanced rescues and supervise Level 1s on rope. Requires 1,000 logged hours and 12 months as a Level 1.
- IRATA Level 3
- Rope access safety supervisor — mandatory on every IRATA worksite. Owns the method statement, risk assessment and rescue plan. Requires 1,000 logged hours and 12 months as a Level 2, plus a valid first-aid certificate.
- TACS
- IRATA's Training, Assessment and Certification Scheme — the document that defines the syllabus, hours and assessment standards for each IRATA level.
- ICOP
- IRATA International Code of Practice — the reference document setting out safe systems of work for industrial rope access.
- Logbook
- The technician's official record of logged rope-access hours and tasks. Used to progress between levels and to evidence currency; hours must support the level a technician claims.
- Revalidation
- The reassessment required to keep certification current. IRATA certificates are valid for three years, after which the technician must be re-assessed.
- TechConnect
- IRATA's online membership and technician-management system, used by member companies to manage training and certification records.
Offshore Tickets
Offshore & safety training
- BOSIET
- Basic Offshore Safety Induction and Emergency Training — the OPITO-standard course (typically 3 days) mandatory to work offshore in oil and gas. Covers helicopter escape, sea survival, firefighting and first aid. No valid BOSIET means no permit to board.
- FOET
- Further Offshore Emergency Training — the refresher for BOSIET, required to keep offshore certification current (usually every four years).
- HUET
- Helicopter Underwater Escape Training — training to escape a ditched, capsized helicopter. Delivered as part of BOSIET for offshore workers.
- OPITO
- The organisation that sets global offshore oil-and-gas safety training standards, including BOSIET and FOET, and maintains the industry's competence records.
- OGUK / OEUK medical
- The offshore fitness-to-work medical taken to the UK offshore energy standard. OGUK (Oil & Gas UK) was renamed OEUK (Offshore Energies UK); a valid offshore medical is required to work offshore.
- GWO
- Global Wind Organisation — sets the safety training standards for the wind industry. Its Basic Safety Training pairs with IRATA for offshore and onshore wind rope-access work.
- GWO BST
- GWO Basic Safety Training — the standard wind-industry safety package: first aid, manual handling, fire awareness, working at heights, and sea survival for offshore.
- WINDA
- The Global Wind Organisation's online database that records a technician's GWO training, used by employers to verify wind-industry safety certification.
Trades
Trade & inspection skills
- NDT
- Non-Destructive Testing — inspection methods that detect flaws in a structure without damaging it. A common trade ticket paired with rope access on inspection contracts.
- UT / UTG
- Ultrasonic Testing (and Ultrasonic Thickness Gauging) — an NDT method that uses high-frequency sound to detect internal flaws and measure remaining wall thickness.
- MT
- Magnetic Particle Testing — an NDT method for detecting surface and near-surface flaws in ferromagnetic materials.
- PT
- Dye Penetrant Testing — an NDT method that reveals surface-breaking defects using a coloured or fluorescent penetrant.
- ECT
- Eddy Current Testing — an NDT method using electromagnetic induction to find surface and sub-surface flaws, common on welds and heat-exchanger tubes.
- PAUT / TOFD
- Phased Array Ultrasonic Testing and Time-of-Flight Diffraction — advanced ultrasonic techniques used for detailed weld and corrosion inspection.
- Blade repair
- Composite repair and inspection of wind-turbine blades, most often performed via rope access and typically requiring combined IRATA and GWO certification.
On Rope
Equipment & technique
- Twin-rope system
- The core rope access safety principle: two independently anchored ropes — a working line and a backup safety line — used on every job so no single failure can drop the technician.
- Working line
- The primary rope a technician ascends, descends and positions on using a descender or ascender.
- Safety line (backup line)
- The second, independently anchored rope that arrests a fall if the working line or main device fails.
- Descender
- A mechanical device fitted to the working line that allows controlled descent and hands-free positioning.
- Back-up device
- A fall-arrest device that runs on the safety line and locks onto the rope if the technician falls.
- Deviation
- A redirect that pulls the rope line to one side to avoid an obstacle or edge, without taking the technician's full weight.
- Re-anchor (rebelay)
- An intermediate anchor that restarts the rope line lower down, used to route around obstructions or protect the rope from an edge.
- Pick-off rescue
- A rescue in which a rescue-capable technician reaches a casualty, transfers them onto the rescuer's system and lowers them to safety. Rescue capability must be on site before anyone goes on rope.
On Site
Work, safety documents & deployment
- RAMS
- Risk Assessment and Method Statement — the safety documentation prepared before work starts, describing the hazards, controls and step-by-step safe procedure. A Level 3 is responsible for it.
- Method statement
- The step-by-step procedure for carrying out a task safely, including the rescue plan. Part of RAMS.
- Permit to work
- Formal, documented authorisation from the site operator to carry out specific work on an asset, often a precondition for rope access on live facilities.
- WAH
- Work at Height — any work where a person could fall a distance liable to cause injury. Rope access is one controlled method of working at height.
- FIFO
- Fly-In Fly-Out — a work pattern where technicians fly to a remote or offshore site for a fixed rotation and fly home for the off period.
- Rotation
- The on/off work cycle of a deployment, such as 2-weeks-on/2-weeks-off onshore or 42/42 offshore. Because rotations are intermittent, a day rate does not annualise cleanly.
- Turnaround / shutdown (TAR)
- A planned period when a facility stops production for inspection, maintenance and repair. Turnarounds create the sharpest, most time-critical spikes in rope-access demand.
- Mobilisation
- Everything required to get a technician deployment-ready and on site: credential verification, visa, offshore medical, travel, accommodation and site induction.
- Deployment-ready
- A technician who is fully verified, compliant and mobilised — certified, medically cleared, ticketed and cleared to work on rope, not just a matching CV.
Regulations
Regulations (UK reference)
- LOLER
- Lifting Operations and Lifting Equipment Regulations (UK) — govern the examination and safe use of lifting equipment, including rope access gear.
- PUWER
- Provision and Use of Work Equipment Regulations (UK) — require work equipment to be suitable, maintained and safely used.
- HSE
- The Health and Safety Executive — the UK's national regulator for workplace health and safety.
Quick answers
Common terms, answered.
What does BOSIET stand for?
BOSIET stands for Basic Offshore Safety Induction and Emergency Training. It is an OPITO-standard course, usually three days, that is mandatory before working offshore in oil and gas. It covers helicopter underwater escape, sea survival, firefighting and first aid, and is renewed with FOET (Further Offshore Emergency Training), typically every four years.
What is the twin-rope system in rope access?
The twin-rope system is the core safety principle of industrial rope access: every technician works on two independently anchored ropes — a working line for positioning and a separate backup safety line that arrests a fall if the working line or main device fails. No single point of failure can drop the technician, which is a major reason IRATA rope access has a strong safety record.
What is RAMS in rope access work?
RAMS stands for Risk Assessment and Method Statement — the safety documentation prepared before any rope access work begins. The risk assessment identifies hazards and controls; the method statement sets out the step-by-step safe procedure and the rescue plan. On an IRATA site, the Level 3 safety supervisor is responsible for producing and enforcing RAMS.
