Enquire About This Course

Introduction

Effective maintenance and capital planning rely on a clear understanding of current and future system capacity and operational load. This course teaches participants how to conduct detailed load analyses, assess the utilization of critical plant systems, and forecast future demand requirements. We will cover methodologies for modeling system performance under various conditions, identifying bottlenecks, and developing capital expenditure plans to address capacity gaps. This strategic course is essential for ensuring that infrastructure and equipment can reliably meet current and projected production demands, avoiding costly over- or under-capacity scenarios.

Objectives

  • Conduct a detailed analysis of asset utilization and operational load profiles.
  • Identify current system bottlenecks and capacity constraints.
  • Develop forecasting models for future production and system demands.
  • Utilize modeling tools (e.g., simulation) to test system capacity limits.
  • Perform an economic justification (ROI) for capacity expansion projects.
  • Understand the impact of asset condition (age, degradation) on effective capacity.
  • Integrate load analysis findings into the Strategic Asset Management Plan (SAMP).
  • Determine optimal maintenance strategies based on the asset's current load factor.
