Life Extension

Service Introduction

Life extension of oil & gas assets, and in offshore wind in the future, is increasingly becoming an important strategic initiative and an attractive alternative to decommissioning. Ensuring the ongoing long-term integrity of an asset means more energy online for more consumers, lower levelized cost of energy (LCOE) and increased value to operators from their infrastructure. But it’s not without significant complications and requires detailed planning, design, and engineering, as well as an in-depth understanding of operational requirements. Longitude blends decades of operational insight with multi-disciplined design, engineering, and analysis, to support clients in getting the most out of their assets without compromising safety or quality. Our approach combines structural integrity, materials assessment, and maintenance optimisation to ensure safe and economical operations beyond design life.
