LARS Retrofit Engineering

Upgrading or replacing an existing Launch and Recovery System (LARS)?

Download our engineering guide to learn how a structured retrofit process helps reduce structural risk, simplify class approval and deliver construction-ready engineering for offshore vessels.

From initial assessment through installation support, the guide explains how integrated engineering creates safer, more efficient retrofit projects.

A LARS retrofit is rarely a straightforward equipment replacement.

Changes to equipment weight, footprint, operational loads and foundation geometry can all affect the vessel's existing structure. Without proper engineering, seemingly minor modifications often lead to redesigns, fabrication delays and class comments.

This guide explains how a coordinated engineering approach validates the vessel before fabrication begins, reducing uncertainty throughout the retrofit.

Engineering every stage of the retrofit

Every LARS retrofit begins with understanding the vessel's existing structural capability.

GLO Marine provides integrated engineering covering:

  • Structural surveys and vessel assessments
  • Load definition and operational analysis
  • FEM and fatigue assessment
  • Foundation and reinforcement design
  • OEM interface coordination
  • Construction-ready drawing packages
  • Class approval support
  • Installation engineering and technical close-out

By coordinating these activities under one engineering scope, we help minimise rework, reduce project risk and support efficient offshore upgrades.

What you'll learn

Assess existing structures

Understand how structural surveys and engineering assessments establish a reliable basis for retrofit design.

Design for real operating loads

Learn how operational load cases, fatigue assessment and FEM analysis validate the vessel before fabrication begins.

Develop retrofit-ready designs

See how foundation layouts, reinforcement details and equipment interfaces are developed into construction-ready engineering packages.

Achieve smooth project delivery

Discover how integrated engineering supports fabrication, installation, class approval and project handover.

A practical guide to successful LARS retrofits


Retrofitting a Launch and Recovery System requires more than replacing equipment. Every modification must be validated against the vessel's existing structure, operational requirements and regulatory obligations.

This guide explains how coordinated structural engineering supports informed decisions from the earliest design stages through fabrication, installation and final approval.

Inside the guide you'll explore:

  • Structural condition assessments
  • Load case development
  • FEM and fatigue analysis
  • Foundation and reinforcement design
  • OEM interface management
  • Class approval strategy
  • Installation support
  • As-built documentation and project close-out

Use it as a practical reference when planning a new LARS installation or retrofit project.


Supporting offshore retrofit projects from survey to class approval

A successful LARS retrofit depends on clear engineering, coordinated stakeholders and a controlled design process.

GLO Marine delivers structural engineering, detailed design, installation support and class documentation for complex offshore vessel modifications, helping owners reduce technical risk while keeping retrofit programmes on schedule.
