Heavy Equipment Integration

Heavy mission equipment introduces structural demands that extend well beyond the equipment footprint.

This engineering guide examines the vessel-side engineering required to integrate offshore cranes, Vertical Lay Systems, cable carousels, drilling packages and heavy modular skids, covering structural assessment, FEM validation, stability evaluation, detailed engineering and multi-society class approval.

Heavy-equipment integrations modify the vessel's global structural response, load distribution and operational envelope.

Concentrated foundation loads, dynamic operating conditions, hull-girder behaviour, fatigue performance and stability all become governing design considerations. These engineering activities must be validated before fabrication and installation begin.

This guide presents a structured engineering methodology for managing the complete integration scope under a single technical baseline.

Inside the Guide

Structural assessment

Evaluate existing structural capacity through surveys, drawing reconciliation, load-path verification and condition assessment.

Global & Local FEM

Assess hull-girder response, supporting structures, foundation behaviour and fatigue performance under operational, transit and survival load cases.

Foundation engineering

Develop pedestal, ring beam, grillage and reinforcement arrangements based on validated equipment loads and OEM interface requirements.

Technical documentation

Produce calculation reports, construction drawings, stability updates and multi-society submission packages supporting project approval and execution.

A technical framework for heavy-equipment integration

Integrating heavy mission equipment requires coordinated engineering across structural analysis, stability, equipment interfaces and certification.

Rather than addressing these activities independently, this guide describes an engineering workflow that establishes a validated structural baseline before progressing to detailed design, fabrication and installation.

Inside the guide you'll explore:

Structural surveys and existing-condition assessment
Equipment load definition
Global and local FEM analysis
Fatigue assessment
Foundation and pedestal engineering
Stability evaluation
Class documentation
Installation and lift-out engineering

Use this guide as a technical reference when planning heavy-equipment integration or offshore vessel modification projects.

Engineering support throughout the integration lifecycle

Heavy-equipment integration requires coordinated structural analysis, foundation engineering, stability assessment and class compliance to ensure that vessel modifications perform safely under operational loading and remain aligned with approved design criteria.
