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

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. 👍 Like, 💬 Comment, and 🔔 Subscribe for more offshore surveying tutorials, geodesy insights, and acoustic navigation techniques. #LBLPositioning #OffshoreSurveying #SpoolMetrology #JacketInstallation #PipelaySupport #SubseaNavigation #MarineGeodesy #AcousticPositioning #RigReentry #AlwaysBeCurious ✅If you want to learn about LBL then following Links Will Help You - Sonardyne Training courses https://www.sonardyne.com/services/tr...
