LUSBL: Long and Ultra-Short Baseline

LUSBL (Long and Ultra-Short Baseline) is an advanced acoustic positioning system developed by Sonardyne, designed to enhance the accuracy and reliability of underwater positioning for dynamically positioned (DP) vessels. By integrating the principles of both Long Baseline (LBL) and Ultra-Short Baseline (USBL) systems, LUSBL offers superior performance in complex offshore operations.

Key Features of Sonardyne's LUSBL System

• Integrated Acoustic Techniques: Combines USBL and LBL methodologies to provide precise and repeatable position references, crucial for DP vessels engaged in critical station-keeping activities.
• Seabed Transponder Arrays: Utilizes a network of seabed transponders, enhancing system integrity and offering redundancy in acoustic positioning. This configuration ensures reliable operations even in challenging environments.
• Compatibility: Interfaces seamlessly with all major DP systems, including those from GE, Kongsberg, MT, Navis, Rolls-Royce, and Wärtsilä, ensuring versatile integration across various vessel platforms.
• Redundancy Options: Supports dual and triple (with Inertial Navigation System integration) independent equipment configurations, allowing operations to continue uninterrupted even if a component becomes unavailable.
• High Update Rates: Delivers position updates at rates up to one second, depending on water depth, facilitating real-time decision-making during dynamic operations.

Applications of LUSBL

• Dynamic Positioning Reference: Provides high-integrity position references for DP vessels, ensuring precise station-keeping during offshore drilling, construction, and heavy-lift operations.
• Subsea Tracking: Enables accurate tracking of Remotely Operated Vehicles (ROVs), Autonomous Underwater Vehicles (AUVs), and other subsea assets, enhancing operational efficiency and safety.
• Telemetry and Data Recovery: Facilitates robust underwater communication, supporting telemetry and data recovery from subsea instruments, which is essential for monitoring and control tasks.

By leveraging the combined strengths of LBL and USBL technologies, Sonardyne's LUSBL system offers a comprehensive solution for underwater positioning, meeting the demanding requirements of modern offshore and subsea operations.
