Before Offshore Becomes Your Workplace
01 — Understand the Environment
Build awareness of the generic hazards associated with offshore oil and gas installations, the risks those hazards can create, and the controls used to reduce them.
02 — Prepare for the Journey Offshore
Develop familiarity with helicopter emergency procedures, safety equipment and the actions required when preparing for and responding to a simulated helicopter emergency.
03 — Survive Beyond the Escape
Practise sea-survival and emergency first-aid techniques so the response continues after leaving the aircraft or installation.
04 — Respond When Visibility Disappears
Use basic firefighting equipment and practise self-rescue techniques in restricted-visibility and simulated smoke-filled environments.
The Safety Induction is delivered as theory while OPITO indicates an approximate 40% theory / 60% practical balance for the remaining unit

01
OIS-01
3 H 20 M
Safety Induction
Understand offshore operations, recognise the hazards and learn how offshore risk is controlled.
The Safety Induction introduces the offshore oil and gas environment, including major installations and vessels, key hazards such as pressure, machinery, H₂S, electricity, work at height and confined spaces, and the relationship between hazard, risk and control. Learners also develop awareness of offshore safety management through barrier systems, Safe Systems of Work, the hierarchy of control, isolation, PPE, Permit to Work, toolbox talks, drills, incident reporting, Safety Case principles, ALARP and personal responsibility for safety.
02
OIS-81
4 H 20 M
Helicopter Safety & Escape — Tropical
Prepare for offshore helicopter travel and develop practical competence for emergency evacuation and underwater escape.
OIS-81 prepares learners for offshore helicopter travel, emergency evacuation and underwater escape. Training covers pre-flight and boarding procedures, correct use of seatbelts and lifejackets, recognition and reporting of abnormal conditions such as fire, smoke and fuel leakage, aircraft flotation and escape routes, together with emergency preparation for ditching or landing, including brace positions and the actions required before evacuation.

OIS-03
6 H 20 M
Sea Survival and First Aid
Move from offshore evacuation into survival craft, in-water survival, rescue and immediate first aid.
OIS-03 develops competence in offshore evacuation, sea survival, rescue and emergency first aid. Learners understand muster and abandonment procedures, escape routes, alarms, PPE and offshore search-and-rescue arrangements, and practise TEMPSC mustering, lifejacket donning, boarding and securing as a passenger. The unit also covers in-water recovery methods and immediate first-aid response to bleeding, burns, chemical exposure and heat or cold injuries, including casualty assessment, scene safety and summoning assistance.
04
OIS-04
3 H 00 M
Firefighting and Self Rescue
Recognise the fire, raise the alarm, use the correct equipment and escape when visibility is lost.
OIS-04 develops practical competence in offshore fire response, firefighting and self-rescue. Learners understand common fire causes, combustion, heat transfer and the use of water, foam and CO₂ extinguishers, together with fire and gas detection, deluge and suppression systems. Training reinforces the correct response on discovering a fire: raise the alarm, select appropriate equipment and evacuate when required. The unit also develops self-rescue in smoke and reduced visibility, including smoke-hood use and escape with or without respiratory protection. Practical exercises progress from reduced to fully obscured visibility and conclude with a small-group escape and muster exercise.
Suraksha Marine HUET Simulator
Train the escape in a controlled helicopter environment.
Product 5501 requires a HUET capable of reproducing representative offshore-helicopter escape conditions.
The training provides at least four learner seats plus space for an instructor, a push-out window for each learner, representative window dimensions, controlled lowering onto and below the water, and the ability to rotate at least 180° in a controlled manner. It also include an emergency stop or brake, rapid retrieval capability, representative helicopter seating and restraints, emergency learner-release arrangements and a nominated helicopter-style exit.

Push-Out Window Competence
The exit is part of the escape sequence.
OPITO requires the learner's ability to operate the push-out window to be assessed during the partial-submersion exercise, even though push-out windows are fitted for the final capsize exercise.
This creates a progressive learning sequence: first establish underwater orientation and basic egress, then add exit operation before combining the skills during capsize.
Demonstrate the exit action before adding the full inversion sequence.
Marine Liferaft
Transition from the water into collective survival.
Learners practise boarding a marine liferaft from the water and carrying out the required initial actions.
Learners understand the location, operation and use of aviation liferafts.

Swimming Ability
You do not need to hide your swimming ability.
These groups must be clearly
identified during pool exercises.
The standard recognises: swimmers, weak swimmers and designated non-swimmers.
A maximum of two designated non-swimmer learners may participate in any one HUET pool exercise.
Inform Suraksha Marine of your swimming ability before practical training.
Shoulder Breadth Measurement
Where required locally, learners should hold a valid Shoulder Breadth Measurement before offshore helicopter travel.
Shoulder Breadth Measurement may be required depending on the applicable offshore aviation regime. Confirm your mobilisation requirement before booking.
Medical Requirements
Learners must be medically capable of participating fully.
T-BOSIET contains physically demanding and potentially stressful activities. Before taking part in practical training, learners must satisfy one of the accepted medical routes specified by OPITO.
Learners must satisfy an acceptable
medical-entry route, which may include:
-
valid offshore medical;
-
employer-approved equivalent;
-
fitness-to-work-at-sea certificate;
-
medical fitness for diving at work;
-
or medical screening by the OPITO-approved centre.
The learner and/or sponsoring company is responsible for declaring known medical conditions that could adversely affect participation. Where fitness is uncertain, the Centre should refer the learner to a medical professional familiar with the nature of the training.
