We are pleased to announce the commencement of the Operations Safety Case development for Belemaoil Producing Limited’s facilities in OML 55.

This comprehensive Operations Safety Case covers four major offshore platforms—Robertkiri, Idama, Jokka, and Inda—all located within Nigeria’s shallow offshore environment at approximately 25m water depth.
OML 55 lies about 40km west of the Bonny Terminal, spanning an estimated 852km² across the mangrove swamp and shallow offshore region of the south-eastern Niger Delta. Previously operated by the NNPC/Chevron Joint Venture, the asset was handed over to Belemaoil Producing Limited, in partnership with NNPC, in February 2015. Current producing fields include Robertkiri, Idama, Jokka, Inda, and Belema North.

Robertkiri Field sits west of Newcross E&P’s Ekulama Field. Its production infrastructure comprises a 12-pile platform with oil and gas processing equipment, a 6-pile utility quarters and helideck platform connected via bridge, and two separate 4-pile structures supporting the heater treater and the LACT metering system along the San Bartholomew River.

Idama Field is developed using a jack-up Mobile Offshore Production Unit (MOPU) and riser platform with capacity for 24,000 bpd of total fluids (15,000 BOPD oil and 9,000 BWPD produced water) and 34 MMscfd of gas. Production from Jokka-1 is tied back to the Idama facilities via manifold.

Inda Field is located approximately 13 km southwest of the Bonny Terminal in 25m water depth, forming part of Belemaoil’s shallow offshore operations.

The development of the Operations Safety Case formally commenced with a field visit and facility inspection to the OML 55 locations from 25th–27th November 2025. The Tomsey team journeyed via speedboats to Robertkiri, Idama, and Inda platforms—an insightful and engaging offshore experience.

The objectives of the facility tour were to:

• Conduct a comprehensive safety assessment to understand existing operational hazards.

• Evaluate the current condition, operability, and functionality of installed equipment.

• Verify the practical implementation of HSE procedures and adherence to Belemaoil’s HSE Management System.

As the project progresses, a Formal Safety Assessment Workshop will be held with full participation from NUPRC.

We extend our sincere appreciation to the Belemaoil team for their continued trust and partnership, and to the onsite personnel for their cooperation and support throughout the field visit.

At Tomsey, we remain committed to delivering world-class Process Safety and Loss Prevention Engineering across Nigeria and beyond. Our expertise covers:

• Development of Operations, Design, and Decommissioning Safety Cases

• HAZID & Bowtie Studies

• HAZOP & SIL Studies

• Design Safety Reviews

• QRA, FERA, EERA, and more

We will continue to support organizations across Nigeria and the region with safe, efficient, and future-ready energy infrastructure solutions.

We are pleased to announce the successful completion of the Hazard and Operability (HAZOP) Study for the Ohaji Flow Station Modification Project executed for SEPLAT Petroleum Development Company PLC.

This milestone represents a critical step in ensuring the safe, efficient, and operable execution of the project. The HAZOP study was conducted in full compliance with international best practices and was facilitated by a multi-disciplinary team comprising process engineers, operations personnel, safety experts, and project stakeholders. The structured and systematic review identified potential process hazards and operability concerns associated with the planned modifications at the Ohaji facility.

We commend the entire project team and SEPLAT PLC for their commitment to safety, professionalism, and operational integrity. With this major milestone completed, we look forward to the seamless execution of the next phases of the Ohaji Flow Station Modification Project
