IS 5194 Right For you?
Helicopter emergency training for personnel travelling offshore.
Product 5194 is designed for personnel new to, or returning to, the offshore industry who are required to travel by helicopter to an offshore asset or facility and will be supplied with CA-EBS during helicopter travel.
The Product is particularly appropriate when the training requirement is centred on: offshore helicopter travel, CA-EBS, helicopter ditching, underwater escape, and sea survival.
Training requirements can vary by operator, region and aviation arrangement.
Before booking, confirm your requirement with your employer, operator or mobilisation team.
Prepare for the flight
Control the escape
Survive the water
Emergency Preparation
Know the escape sequence before the aircraft reaches the water.
Learners develop an understanding of: aircraft flotation characteristics, emergency landing and ditching, escape routes, aviation lifejackets, brace positions, seat and harness configurations, independent action and survival following ditching.
Core response:
LOCATE
Identify the nominated exit.
>>
Release
Release the restraint at the appropriate stage.
>>
Evacuate
Move through the nominated exit or push-out window during on-water, underwater or capsized conditions.
Recognise when the crew needs to know.
Learners develop awareness of abnormal conditions that should be reported to the helicopter crew, including: fire, smoke, fuel leakage, and other unusual conditions the crew may not have identified.
Training also reinforces maintaining a secure seatbelt, correctly positioned lifejacket and following crew instructions.
Three Mandatory Units
01 — OIS-81
Helicopter Safety and Escape — Tropical
4 Hours 20 minutes
OIS-81 develops the knowledge and practical actions required for offshore helicopter travel and emergency escape in a tropical operating environment.
The unit begins before the emergency itself. Learners develop an understanding of normal offshore helicopter travel requirements including pre-flight briefings, correct dress, documentation, prohibited articles, check-in, safe boarding and in-flight procedures. They also learn when abnormal conditions such as fire, smoke, fuel leakage or other hazards should be reported to the flight crew.
The training then moves into helicopter emergency preparation. Learners develop an understanding of basic aircraft flotation characteristics, escape routes, aviation lifejackets, brace positions, restraint configurations and survival actions following ditching or emergency landing. The evacuation sequence emphasises locating the nominated exit, releasing the restraint at the appropriate stage and evacuating through the required exit or push-out window.
02 — OIS-276
Helicopter Emergencies & CA-EBS
OIS-276 focuses specifically on the Compressed Air Emergency Breathing System (CA-EBS) used during offshore helicopter travel.
The unit develops both technical understanding and practical equipment competence.
Learners first understand the operating principles of CA-EBS and how compressed-air systems differ from other emergency breathing systems used offshore, including rebreather systems.
Learners also understand how CA-EBS interacts with other survival equipment such as the aviation lifejacket and Personal Locator Beacon where applicable.
03 — OIS-83
Sea Survival — THUET
4 Hours
OIS-83 develops the knowledge and practical actions required once a learner has evacuated an offshore installation or escaped into the water.
The unit connects HUET with the wider offshore survival chain:
EVACUATE → SURVIVE → BOARD → GROUP → RESCUE
Learners first develop an understanding of typical offshore emergencies, including those involving floating installations such as FPSOs and drilling rigs, together with station bills, means of escape and actions before, during and after evacuation.
Why Tropical HUET with CA-EBS?
Because helicopter travel creates its own emergency-response sequence.
Travelling offshore involves a combination of hazards that many personnel may not encounter in conventional workplaces.
Personnel may need to: maintain restraint, locate an exit, operate a push-out window, escape from a submerged cabin, respond after inversion, use survival equipment and transition from egress into sea survival.
Product 5194 is specifically designed to develop these competencies for tropical offshore helicopter travel.
Helicopter emergency response and survival in one focused pathway.
Learners are required to demonstrate that they can:

The learner then progresses into practical use.
CA-EBS Shallow-Water Familiarisation
Build breathing-system competence progressively.
The Product includes dedicated CA-EBS exercises in shallow water at a maximum depth of 0.7 metres measured at the chest.
Learners practice: deployment above the water, deployment below the surface, clearing the mouthpiece by exhalation, using the purge function, deployment using opposite hands, breathing underwater vertically and moving underwater while breathing from CA-EBS.

These variations form part of the practical Product 5194 HUET sequence.
HUET Escape Progression
Increase the challenge one element at a time.
HUET training increases in complexity as learners develop confidence and competence.
The minimum HUET team includes:
Lead Instructor
Crane/Hoist Operator or Dive Supervisor
OPITO HUET Divers
Pool Safety Person
Push-Out Window Competence
Operate the exit before the most complex scenario.
An important assessment detail within the Product Standard is that although push-out windows are fitted for the final capsize exercise, the learner's ability to push out the window is assessed during the partial-submersion exercise.
This is a good example of progressive competence development:
Aviation Liferaft
Helicopter emergency knowledge: learners cover aviation liferaft stowage, operation, entry and initial actions after boarding.
Product 5194 includes dry evacuation from a simulated ditched helicopter into an aviation liferaft, as well as liferaft boarding from the water following HUET egress.
Learners revisit initial liferaft actions including:

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
Be fit for the practical demands of training.
Product 5194 contains activities that may be physically demanding and potentially stressful.
Learners must satisfy an acceptable
medical-entry route, which may include:
-
valid offshore medical;
-
employer-approved equivalent;
