ROV BackPack System for Isolated Tooling Operations

Overview 

Innova delivered a complete ROV BackPack solution to a major EPC contractor, enabling safe and flexible operation of external subsea tooling using isolated hydraulic systems. 

Challenge 

The key challenge was providing sufficient power and control for external tooling while preventing contamination of the ROV’s primary hydraulic system. This required a compact, fully integrated solution that could operate independently without compromising ROV performance. 

Solution 

Innova developed a self-contained backpack system based on its proven Valve Pack 6ch NG6 platform, featuring: 

• Dedicated hydraulic system with reservoir, filtration, and motor/pump assembly 

• Isolated fluid circuits supporting “dirty” hydraulics and alternative fluids 

• Ethernet and serial control via integrated PIO36 control board 

• Lightweight DNV 2.7-3 aluminium frame with integrated buoyancy 

A complete topside package, including HMI, control panel, and test unit, ensured efficient integration and operation. 

Result 

A compact and robust add-on system that increases ROV flexibility, protects core hydraulics, and enables safe, efficient subsea intervention with external tooling.
