IOCL Bongaigaon Apprentice Recruitment 2026 - Apply Online for 58 Trade, Technician Apprentice Posts

Candidates applying for the Trade Apprentice – Attendant Operator (Chemical Plant) or Trade Apprentice (Boiler) posts must have completed a full-time B.Sc degree from a recognized university. Part-time, distance, or correspondence degrees are generally not accepted for refinery technical training positions. The academic background in Chemistry, Physics, and Mathematics provides the required theoretical foundation for handling complex chemical process units and steam generation utilities safely.

For the Technician Apprentice – Instrumentation role, applicants must possess a 3-year regular Diploma in Instrumentation Engineering or closely aligned disciplines. If you need to verify whether your date of birth falls within the prescribed limits considering category relaxations, use the age calculator before submitting your form online.

• Trade Apprentice (Attendant Operator / Boiler): Monthly stipend as per Apprenticeship Rules (typically ₹9,000 to ₹10,500 per month during training).
• Technician Apprentice (Instrumentation): Monthly stipend as per Apprenticeship Rules (typically ₹10,500 to ₹12,000 per month during training).
• Allowances & Benefits: Stipend only; no HRA, DA, TA, or performance bonuses during the apprenticeship period.

Under the Apprentices Act, 1961, an apprenticeship stipend is not a regular salary. It carries no National Pension System (NPS), Provident Fund (PF), Dearness Allowance (DA), or House Rent Allowance (HRA) deductions or additions. The full monthly stipend amount is remitted directly to the apprentice's bank account, subject only to applicable personal income tax rules if the total annual income exceeds exemption thresholds. Compared to entry-level private sector internships, training at an IOCL refinery provides exposure to large-scale industrial infrastructure, high-pressure steam boilers, and continuous process control units. Completing this one-year training yields a National Apprenticeship Certificate (NAC), which significantly improves employment prospects for permanent Junior Engineering Assistant (JEA) recruitments across public sector oil and gas refiners, petrochemical plants, and heavy processing industries.

Applications for IOCL apprenticeship seats are screened automatically and manually. Errors during the registration process frequently result in immediate rejection. Below are the primary reasons applications are turned down:

• Incorrect Portal Registration: Trade Apprentices (B.Sc) and Technician Apprentices (Diploma) must register on their designated official portals. Registering under the wrong portal or establishment code leads to application invalidation.
• Non-conforming Photo and Signature Formats: Uploading blurry, low-resolution, or incorrectly sized photographs causes rejection during automated document verification.
• Incomplete Marks Entry: Entering incorrect percentage calculations, omitting semester marks, or calculating CGPA wrongly without following the university conversion formula.
• Category Claim Without Valid Certificates: Claiming SC, ST, OBC-NCL, or PwBD status without possessing a valid central government format certificate issued before the specified cut-off date.
• Age Miscalculation: Applying without accounting for exact cut-off date rules, leading to disqualification if the candidate exceeds 24 years (for General category) by even a single day.
• Prior Apprenticeship Experience: Candidates who have already undergone or are currently undergoing apprenticeship training under the Apprentices Act in any establishment are ineligible.

Once the document verification and medical fitness tests are cleared, selected candidates receive a formal letter of engagement specifying the commencement date of apprenticeship training at Bongaigaon Refinery, Assam. The onboarding process involves completing administrative documentation, signing the apprenticeship contract registered with apprenticeship authorities, and undergoing safety induction training.

During the 12-month training period, apprentices are assigned to various operational units, laboratories, boiler houses, or maintenance shops under experienced refinery supervisors. After successful completion of the period and passing the assessment, candidates are awarded the National Apprenticeship Certificate. The total timeline from the closing date of applications to the final joining is typically 2 to 3 months.

Indian Oil Corporation Limited (IOCL) is India's largest commercial enterprise and a Maharatna Public Sector Undertaking under the Ministry of Petroleum and Natural Gas. Established in 1959, Indian Oil operates a vast network of oil refineries, cross-country pipelines, fuel stations, and petrochemical complexes across the nation. The company accounts for a major share of India's petroleum products market and plays a strategic role in ensuring the country's energy security.

The Bongaigaon Refinery, located at Dhaligaon in the Chirang district of Assam, was integrated into IOCL in 2009. Originally established in 1974, it processes crude oil to manufacture liquefied petroleum gas (LPG), motor spirit (petrol), high-speed diesel, aviation turbine fuel, and petrochemical feedstocks. It serves as a major industrial employer in the region, operating under strict environmental, safety, and operational protocols.

Trade Apprentices (Attendant Operator Chemical Plant and Boiler) work closely with refinery operational teams managing continuous chemical processing units, distillation columns, reaction vessels, and steam utilities. Their daily routines involve monitoring temperature, pressure, and flow rates on field instruments, assisting in chemical sample collection, checking pump operations, and learning industrial safety measures, hazard identification, and emergency response procedures.

Technician Apprentices in Instrumentation focus on field instruments and control systems. They assist maintenance engineers in calibrating control valves, pressure transmitters, temperature sensors, flow meters, and Distributed Control Systems (DCS). The role combines desk-based diagnostic reading with hands-on field troubleshooting across processing units, operating in a shift pattern within an industrial refinery environment under direct supervisory control.
