Why T-BOSIET is the working certificate on the western offshore
The platforms off Mumbai sit in warm water, and OPITO's tropical standard was written for that environment. It covers offshore hazards and controls, helicopter escape after a ditching, sea survival, first aid, firefighting and self-rescue in smoke, and it totals 19 guided learning hours over four units. Mumbai crews are also unusual in how they reach the field: helicopters have flown out of Juhu aerodrome to the ONGC installations since October 1986, and a 2012 account counted roughly 35 to 36 take-offs and landings a day carrying about 350 ONGC employees. Anyone who boards those flights needs training in helicopter escape, which is why the tropical version includes it.
The installations themselves are varied, which affects the work you will do. The Neelam field lies roughly 45 km south-west of Mumbai and has been the subject of platform life-extension and redevelopment work. The Tapti cluster sits 160 to 200 km north-west of Mumbai in water only 20 to 30 m deep. The Bassein processing complexes, BPA and BPB, were commissioned in 1987 and 1989 and handle acidic gas that contains H2S before it goes on to Hazira. The jobs range from hook-up crews to process operators and inspection teams, but they share one entry requirement: a valid induction.
Mumbai also supplies the contract workforce. Engineering, fabrication, catering and logistics firms recruit in the city and place staff on platforms for weeks at a time. For a first-time candidate the sequence is simple: the posting is confirmed, T-BOSIET is requested, and the candidate books three days in Kochi.
Juhu aerodrome helicopter operations
Pawan Hans has flown ONGC crew from Juhu to offshore installations since October 1986, according to the operator's profile.
Neelam field
About 45 km south-west of Mumbai; platforms have been through redevelopment and life-extension work.
Tapti cluster
160 to 200 km north-west of Mumbai in 20 to 30 m of water.
Bassein complexes BPA and BPB
Process complexes commissioned in 1987 and 1989 that handle acidic gas containing H2S.
Mumbai jobs that ask for T-BOSIET
Hook-up, fabrication and modification crews
Contractors that work on platform revamp and life-extension jobs mobilise from Mumbai yards and offices and need every worker inducted.
Inspection, NDT and instrument technicians
Short campaigns offshore mean frequent helicopter transfers, so the helicopter escape component is directly relevant.
Catering and housekeeping staff
Accommodation and catering contractors place staff on manned platforms and ask for the same induction.
Recruits placed by Mumbai manning agencies
Agencies often require the certificate before they will submit a profile to a contractor.
T-BOSIET, BOSIET, T-HUET or a refresher
Start from where your client works. For a contract on the western offshore, T-BOSIET is the version that matches the water temperature. If the same contract might put you in the North Sea or with an operator that names the standard version, ask your agency to confirm before you spend ₹35,000, because BOSIET with EBS is a different certificate with aviation suits and a breathing system. If you only need helicopter escape, T-HUET may be enough. Some operators in warm regions issue an emergency breathing system for helicopter flights, and OPITO has a separate standard (code 5900) for that, taken with T-BOSIET or T-HUET; ask your employer if it is needed and our team if we run it. If you hold a valid T-BOSIET and a new contract wants the standard version, OPITO also publishes a bridging element, though availability varies by centre.
Basic Offshore Safety Induction and Emergency Training with EBS (BOSIET with EBS) →
The contract names the standard version, or the job may be outside warm-water regions.
Tropical Helicopter Underwater Escape Training (T-HUET) →
You only need helicopter underwater escape in the tropical form, for example to complete a missing module.
Tropical Further Offshore Emergency Training (T-FOET) →
You already hold a valid T-BOSIET and are within its last months of validity.
Basic H2S Training →
The platform or plant handles sour gas; it is a separate half-day course.
The four T-BOSIET modules, for the Mumbai offshore
The course mixes classroom theory with instructor-led practical exercises. Helicopter escape and sea survival are practised in an indoor pool with a Modular Egress Training Simulator, and fire and smoke exercises take place on a fire ground. Assessment is continuous and practical, so you must demonstrate competence in every exercise before the certificate is issued.
- 01
Safety induction
Offshore hazards and risk controls, the safety legislation and management systems in force, and roles and responsibilities. It is the briefing for your first day on a Mumbai High or Neelam platform.
- 02
Helicopter safety and escape (tropical HUET)
Helicopter travel hazards in tropical regions, brace positions and escape from a capsized, submerged helicopter. It prepares you for the platform flights most Mumbai crews take.
- 03
Sea survival and first aid
Tropical sea survival techniques without an immersion suit, lifejackets, life rafts, hyperthermia considerations and basic first aid. The warm-water focus is the main difference from the standard course.
- 04
Firefighting and self-rescue
Fire hazards and prevention, portable extinguishers and escaping a smoke-filled space. On a gas-handling platform, leaving a smoke-filled module quickly is the point.
For Mumbai contractors and recruiters booking T-BOSIET
Engineering and fabrication firms, accommodation and catering contractors, inspection companies and manning agencies in Mumbai typically send offshore-bound staff in cohorts timed to a mobilisation. A fixed three-day course in Kochi suits that pattern.
Standards that shape training in Maharashtra
OPITO T-BOSIET standard (5501)Four mandatory units; the maximum gap before the T-FOET refresher is four years.
Medical entry requirementAccepted routes include an offshore medical certificate, an employer-approved equivalent, a fit-to-work-at-sea certificate or the centre's own screening form.
OPITO emergency breathing system standard (5900)A separate OPITO standard, delivered with T-BOSIET or T-HUET, for staff issued an EBS on warm-water helicopter flights.
Operator and contract wordingWhether the induction must be tropical or standard, and whether an EBS is needed, is set by your client, not by a general rule.
What employers commonly ask for
| Course | Requirement note |
|---|---|
| Tropical Basic Offshore Safety Induction and Emergency Training (T-BOSIET) | Commonly asked for by contractors working in tropical waters, including the western offshore. |
| Basic Offshore Safety Induction and Emergency Training with EBS (BOSIET with EBS) | Named in some contracts, especially when staff could be deployed outside warm water. |
| Tropical Further Offshore Emergency Training (T-FOET) | The refresher before the four-year point. |
| Basic H2S Training | Where assets handle sour gas; confirm for your site. |
Planning a group booking
- Create a company account at portal.imostacademy.in/register for team logins, rate-card pricing, group bookings, statements and certificate tracking.
- Invoices are issued with GST; purchase orders are accepted and credit terms follow a credit assessment.
- Collect each person's medical evidence before booking and get the course name from the client in writing.
- Book a few days ahead of mobilisation in case an assessment needs a second attempt.
Operators and clients set their own requirements; confirm with your contract or HSE department.
Mumbai to Kochi for a three-day course
The campus is in Njarakkal, on Vypin island, a road transfer from Kochi's airport and railway junction. Flights from Mumbai take about two hours.
Evening flight, morning start
Choose a flight that lands in Kochi the evening before day one so that you are rested for the pool sessions. Fly home on the evening of day three, or the next morning for margin.
Airport to campus
Cochin International Airport is about 40 km from Njarakkal, usually just over an hour by taxi, depending on traffic.
Konkan route to Ernakulam
The overland route takes a day or more. It rarely makes sense for three days of training unless you are combining it with leave.
