Raptor Remote Intervention Tool (RIT)

A remotely operated subsea drilling and anchor installation system for challenging offshore renewable environments.

The Raptor Remote Intervention Tool, or RIT, is essentially a multifunctional subsea crawler platform designed to carry out intervention and seabed operations without relying on large conventional ROV spreads or diver-based operations.

It has integrated manipulation capability, tooling interfaces, cameras, sonar, and anchoring functionality, which means it can undertake a range of subsea activities from inspection and surveys through to anchor handling and maintenance scopes.

Importantly, it’s designed around a relatively low logistical footprint compared with larger traditional systems, which is a major advantage for nearshore renewables, offshore wind, and future tidal projects. The system aligns closely with the wider direction of travel in offshore operations: reducing offshore personnel exposure, lowering vessel and operational cost, and increasing flexibility in how intervention work is delivered.

Key features

Key features & specifications

Tracked Vehicle System

A tracked (crawler) system, designed for stability on the seabed.

Anchoring System

An anchor gripping system for secure attachment to components.

Manipulator Arm

Equipped with a manipulator arm, such as the Schilling Orion 7 RE, for various intervention tasks.

Power & Hydraulics

240 V, 13 A electrical input, providing 33 kW / 60 LPM / 207 bar hydraulic power for tools.

Sonar & Cameras

Sonar such as the Gemini 720id, plus multiple cameras including pan & tilt for navigation and work supervision.

Depth Rating

Designed for operating depths up to 100 metres.

Typical applications

The RIT can connect and operate anchor tensioning tools (ATT) with a 100 t rated pretension load; it is designed for installation and maintenance tasks on offshore wind farms; and with integrated cameras and sensors it can perform subsea surveys and inspection. The RIT provides a lightweight, lower-cost alternative for seabed work, supporting the energy transition by enabling remote operations — a flexible, “plug-and-play” solution that reduces the environmental footprint of subsea work.
