Untethered Subsea Load Monitoring System

Overview

Innova delivered a fully untethered load monitoring system to measure and document forces in critical lifting points on a subsea lifting frame, supporting safe recovery of spools and pipelines.

Challenge

The main challenge was providing accurate, real-time load monitoring without relying on cables or ROV connections. This required a fully self-contained system with reliable power, clear data visualization, and complete operational flexibility.

Solution

Innova developed a compact, cable-free system integrating sensing, display, and power, featuring:

• Subsea load sensors integrated directly into lifting pins
• Real-time load visualization in metric tonnes via subsea displays
• Battery-powered operation eliminating external connections
• Automatic idle mode to extend operational endurance
• Continuous data logging for full post-operation verification
• The untethered design allowed full independence from ROV systems during lifting operations.

Result

A flexible and reliable monitoring solution that improves safety, enhances operator awareness, and simplifies offshore operations—while providing complete, verifiable load data for post-job analysis.
