How to Use LBL in Offshore Projects | Pipelay, Jacket Installation & Spool Metrology Explained

Описание: In this second part of our LBL (Long Baseline) series, we dive deep into how LBL systems are used in real-world offshore operations—from pipelay support and jacket installation to spool piece metrology and rig re-entry. If you're a surveyor, engineer, or offshore operator, this video offers practical insights into planning, deploying, and calibrating LBL arrays for high-precision subsea positioning.

📐 What you’ll learn:

How LBL supports ROV, AUV, USV navigation and structure positioning
Environmental factors affecting LBL accuracy: seabed topography, noise, reverberation, and scattering
👉Planning considerations: sound velocity, tide, inclinometer, gyro, and mounting designs
👉Calibration methods for individual and array-based compatts
👉12 critical pre-deployment checks for successful LBL operations
👉*Real-world examples:*
✔Pipelay corridor setup and touchdown monitoring
✔Jacket installation with fabrication yard prep and DIMCON survey
✔Spool piece metrology: flange alignment, seabed profiling, and azimuth determination
✔Rig re-entry using mobile compatt arrays and wellhead positioning

✅Whether you're working from a DP vessel, non-DP vessel, or barge, this tutorial simplifies complex LBL workflows and highlights the precision advantages of acoustic positioning in challenging subsea environments.
