X-net System Modular Sensor Deployment and Retrieval

Introduction

X-net® system is a modular sensor deployment and retrieval system for environmental monitoring and surveying. The infrastructure is expandable to as many connection points as needed and can be adapted according to the requirements of a given project. The system allows integration by cables or as stand alone units. Cabled systems can use fibre optics for communication between nodes and can support power supply of 3.0 kV AC.

The system is designed to allow maximum flexibility in customization with minimal engineering expense.

The components are:

• X-Node® which is a ‘docking station’ for an X-Frame ®, providing power and communications distribution to the X-Frame in a cabled set-up. The X-Node will step down system voltage to as needed for supply to the X-Frame. The X-Node is not designed for easy retrieval, as a docking station it is intended to be a permanent resident on the sea bed until the project is complete.
• X-Frame® is the deployable unit which houses all of the sensors, cameras, data collection & storage, and any battery systems. The X-Frame is easily retrievable using an ROV running tool or using the Landing and Retrieval Tool (X-LRT) which allows installation without the support of an ROV.
• X-SAT® is a secondary external sensor platform for cameras, flash and specific sensors. It is linked to an X-Frame with a wet mate connector for power and signal.
• X-LRT® is the Landing and Retrieval Tool for X-Frames, which allows installation of an X-Frame on an X-Node or base unit without the support of an ROV.
