& Maintenance

Support to Operations

Fast Facts

  • Responsible for pre-startup, commissioning, post-startup, and shutdown readiness services for some of Nigeria’s most critical assets including the NLNG plant (which produces 10% of the world’s LNG supply) and the Bonga FPSO (2 million barrel storage capacity).
  • Delivered operability and maintainability studies and guides for major investments including Shell’s Gbaran Ubie project (gas processing capacity 1 billion scfd) and the Sea Eagle FPSO (1.4 million barrel storage capacity).
  • Nexus CMMS and corrosion management services are in operation at over 17 major energy installations, including Nigeria’s largest gas plant – the Shell Soku plant. Soku processes about 4% of the gas that enters the global LNG market annually.
  • 13 major IOC energy facilities in the Niger Delta are currently being operated using operational technical manuals developed by our team.

Case Studies

Operability and Maintainability Studies – Sea Eagle & Bonga FPSOs

During this project, Nexus Alliance:

  • Identified equipment that have no redundancy and equipment that have flawed redundancy and developed appropriate and relevant maintenance plans.
  • Identified and recommended remedies for design anomalies that impact on maintainability of assets.
  • Reviewed and identified maintenance strategies that require total plant shutdown. Assessed if such strategies are relevant or if alternative strategies are required.
  • Quantify the impact of deferment if shutdown for maintenance Reviewed existing maintenance strategies and rationalized the value of such strategies and recommend changes.
  • Recommended industry best practices to maximizing availability and reliability at a lower cost.

Maintenance Integrity & Execution (MIE) Training & Implementation Support

  • Nexus has provided Maintenance Integrity and Execution( MIE) Training and Implementation/Support for Shell Nigeria (SPDC and SNEPCO).
  • Nexus delivered the Shell Global Process Guide training/Coaching for Work Preparation, Scheduling & Execution Operation Excellence (OE) for the East and West facilities.

Consultancy Services for Relentless Production Improvement (RPI)

Our deliverables under this service include:

  • Implementation of standardized work in line with the RPI process guide. Work with field and office supervisors to develop a structured program.
  • Coach field supervisors on data collection, reporting and analysis of first line maintenance logbooks with the aim of identifying defects and eliminating before they cause major failures/deferments.
  • Conduct kaizen workshops with field staff and handhold SPDC staff to achieve 6-sigma certification.
  • Set up maintenance consumable stores /management systems and Kanban systems for reordering consumables.

Facility Turnaround Shutdown Optimisation (TARS-OP) & Assistance programs

  • Nexus Alliance conducted Turnaround/Shutdown studies for two SNEPCO FPSOs – Bonga and Sea Eagle.
  • The Nexus Turnaround/Shutdown Optimization (TARS-OP) program revealed inefficiencies and opportunities for improved workforce productivity.
  • The program also helped SNEPCO to identify short and long term shutdown cost improvement opportunities as well as opportunities for reduction in shutdown duration.
  • This program has become part of SNEPCO’s continuous improvement framework and provides a baseline for future comparisons.

Reliability, Availability, Maintenance & Safety (RAMS) Consultancy Services

The scope of our consultancy services include:

  • Provision of independent assessments of systems/equipment on Bonga and EA assets for their maintainability without a system or plant shutdown.
  • Identification of systems and equipment that have no redundancy for routine maintenance.
  • Identification of maintenance plans and items from SAP that requires unit/plant shutdown with their expected deferment value in boe.
  • Suggest solutions to such systems/equipment’s for further engineering to enable doing maintenance without a system or plant shutdown.
