SERVICES
The detail behind the capability.
Our scope spans power, electrical and instrumentation, drilling waste, marine mobilisation, mechanical maintenance, procurement and HSE-led manpower. Each discipline is set out in full below: what it involves, the systems behind it, and where it has already been delivered.
HOW WE WORK
Every scope is run to the operator's own housekeeping and performance standard, documented, and handed back verified. Generating sets are returned on load with panel parameters recorded. Repairs are root-caused, not patched. Crews work under full permit-to-work and HSE control. The standard does not change with the size of the job.
SERVICE LINES
Seven disciplines, in depth.
Power Generation & Rotating Equipment
GENSET ON LOAD · NAOC

ON RECORD
NAOC Obama: a CAT 3512 alternator overhauled, AVR, exciter, PT and diodes replaced, returned to service after load testing.
See the NAOC case →Electrical & Instrumentation
Generator control and protection, power systems and field instrumentation, with fault diagnosis to component level.
WHAT IT COVERS
Voltage regulation (380 to 400 V), potential transformers, exciter circuits, control panels, EIS modules, load-test and parameter verification.
ON RECORD
A CAT D34-12 returned to service with confirmed panel readings of 419 V, 50.3 Hz and 278 A; a Mitsubishi set diagnosed and rectified to restore station power.
See the NAOC case →Drilling Waste Management
TRIDENT VIII RIG · CHEVRON
Evacuation and transfer of drill cuttings and spent fluids from live offshore drilling.
WHAT IT COVERS
Submersible hydraulic pump spreads with primary and redundant skid-mounted power units, mud-boat positioning and station-keeping, water-based mud transfer.
ON RECORD

See the Chevron case →Marine & SPM Mobilisation
Mobilisation, transport and field execution for marine and offshore structures, including single point moorings.
WHAT IT COVERS
SPM buoy mobilisation and loading, self-propelled modular transporters, field works and support-vessel coordination.
ON RECORD
SOFEC SPM-C1 for Dangote Petroleum Refinery at Ibeju-Lekki: buoy moved on modular transporters and mobilised, one of the largest of its kind on the continent.
See the Dangote case →Mechanical & Plant Maintenance
Mechanical maintenance, fault rectification and turnarounds on producing plant, to operator housekeeping standards.
WHAT IT COVERS
Drive-belt systems (strip-down, OEM replacement, alignment, load test), cooling, lubrication, air and fuel systems, post-repair verification.
ON RECORD
Brass Export Terminal (Oando): a CAT C32 drive-belt failure stripped, root-caused, replaced and load-tested back into service inside the shutdown window.
See the Oando case →Procurement & Logistics
Sourcing OEM-spec parts, expediting, and moving equipment and crews to remote, access-controlled sites.
WHAT IT COVERS
OEM spares for CAT and Mitsubishi fleets, offshore and creek logistics, vessel and transporter coordination.
ON RECORD
Spreads and spares delivered to offshore rigs, creek flow stations and export terminals across the Niger Delta.
HSE-led Manpower
Competent, certified crews deployed onto live assets under strict permit-to-work and operator HSE regimes.
