Energy giant Sahara Group has rolled out a proprietary, group-wide predictive maintenance and asset intelligence framework that is already delivering major gains in reliability, cost efficiency and safety across its operations.
The framework, known as OPTIMA-MAINT, was developed internally to move the Group away from largely reactive and calendar-based maintenance practices towards a data-driven, predictive and reliability-centred model. According to internal performance records, locations with full deployment have recorded about a 40 per cent reduction in unplanned downtime and over 30 per cent savings in maintenance-related costs.
OPTIMA-MAINT was designed and led by Godwin Uchechukwu Uke, Manager, Terminal Maintenance at Asharami Synergy, a Sahara Group company. The framework is detailed in a white paper dated December 16, 2022, which outlines its architecture, implementation roadmap and measurable impact across terminals, depots and critical infrastructure assets.
Before the introduction of OPTIMA-MAINT, Sahara Group faced long-standing structural challenges common to large, asset-intensive organisations. These included frequent unplanned breakdowns of critical equipment such as pumps, loading arms, filtration units and electrical systems; fragmented maintenance data spread across multiple systems and manual records; inconsistent maintenance standards across locations; and rising operating costs driven by a mix of emergency repairs and excessive preventive work. The result was lost throughput, schedule disruptions, uneven performance across sites and higher total cost of ownership for key assets.
OPTIMA-MAINT was conceived as a scalable and standardised response to these challenges. It brings together asset data, reliability engineering, predictive analytics and governance into a single framework that supports better maintenance decisions across the Group. The system establishes a standardised asset registry, integrates condition monitoring data and links maintenance systems with enterprise platforms. It applies structured failure analysis, criticality ranking and reliability modelling to predict failures and estimate remaining useful life, then converts these insights into actionable decisions on maintenance intervals, work prioritisation, spare parts planning and repair-versus-replacement choices.
To ensure sustainability, the framework embeds governance through group-wide standards, performance dashboards, training programmes and periodic reviews. This ensures that maintenance improvements are not one-off gains but part of a continuous improvement cycle aligned with business priorities.
Rather than a sudden, disruptive rollout, Sahara Group implemented OPTIMA-MAINT through a phased, multi-year approach. Initial pilot deployments at high-impact terminals and depots focused on cleaning up asset data, conducting failure analyses and testing early reliability models. These pilots delivered early evidence of downtime and cost reductions, validated the framework’s tools and templates, and highlighted organisational enablers and gaps.
Building on this foundation, the framework was scaled to additional locations over subsequent years, supported by standardised policies, training and dashboards. OPTIMA-MAINT outputs were integrated into operations planning, HSSE risk management, finance and supply chain decisions, allowing performance to be benchmarked across sites and best practices to be shared. The framework is now embedded in group maintenance policies, audit criteria and capital expenditure governance, making adherence to its principles a requirement rather than an option.
Measured results from fully deployed locations show clear improvements. Average monthly unplanned downtime has fallen by about 40 per cent, maintenance cost indices have dropped by more than 30 per cent, and emergency work orders as a share of total maintenance activity have been reduced by roughly half. Availability of critical assets has improved from the low 90 per cent range to about 97 per cent, strengthening throughput and service reliability.
Beyond financial and operational gains, OPTIMA-MAINT has delivered HSSE benefits. Fewer emergency breakdowns mean fewer high-risk interventions, while improved documentation and traceability have strengthened audit outcomes and regulatory compliance, particularly in aviation and fuel-quality-sensitive operations.
The framework is now used across Sahara Group’s functions. Operations teams rely on its availability and downtime metrics for performance management. HSSE teams incorporate its failure and criticality analyses into risk registers and barrier management plans. Finance uses its lifecycle cost models to evaluate budgets and capital replacement proposals. Supply chain teams align spare parts strategies with risk-based insights, while IT supports system integration and real-time visibility through dashboards.
Senior executives and board members have described OPTIMA-MAINT as transformational, noting that it has strengthened the Group’s risk posture, improved transparency in maintenance expenditure and underpinned reliability assumptions in strategic planning. They credit the framework with elevating maintenance from a narrow technical function to a strategic business lever.
Sahara Group plans to deepen the framework’s capabilities through advanced analytics, real-time dashboards, tighter integration with operational data systems and, over time, digital twin concepts for critical assets. There are also plans to link maintenance decisions more explicitly with energy efficiency and sustainability metrics.
