#PRObed! “Take Me Home” Mode | How Shaft Generator Runs as Motor During Main Engine Failure

#PRObed! Shaft Generator Running as Motor | Emergency “Take Me Home” Mode 🗓 Date: 28 July 2023 🌊 Location: Open Sea 🛳 Test: PTH Mode (Power Take-In) a.k.a. “Take Me Home” Mode What happens when the Main Engine fails mid-voyage? In this rare onboard test, we activated the “Take Me Home” mode, allowing the Shaft Generator to run as a Motor—powered by Diesel Generators—to rotate the propeller shaft without the Main Engine. ⚙️ This is real-life redundancy engineering at work. Modern vessels with both PTO (Power Take-Off) and PTI (Power Take-In) offer a safety net that can literally take you home. 📌 In this first-person walkthrough, you’ll see: ✔️ Step-by-step activation of PTI (PTH) Mode ✔️ Emergency propulsion without Main Engine ✔️ Clutch disengagement & switching from PTO to PTH ✔️ Power delivery by DGs to the shaft generator ✔️ Reverting safely back to normal operation ⏱️ Timestamps 🔧 TIMESTAMP SUMMARY 00:00 – Introduction: Emergency Operation of PTH Mode 00:09 – Overview of PTI/PTH (Power Take-In) System 00:50 – Difference Between PTO (Normal) and PTI/PTH (Emergency) Modes 01:28 – Step-by-Step Activation of PTH Mode 02:42 – Switching Shaft Generator Panel from PTO to PTH 03:04 – Activating PTH from PMS and PCS Displays 04:32 – Engaging the Clutch and Monitoring System Indicators 05:54 – Confirmed: System is Now in PTH Mode 06:18 – Bridge Control Takes Over for Propeller Pitch 07:38 – Shaft Generator Now Running as Motor 15:42 – Ship Speed Ramps Up to 9–10 Knots Under PTH 18:12 – 3 Diesel Generators Delivering ~938kW for Propulsion 19:59 – Begin Shutdown and Reversion to PTO (Normal Operation) 22:27 – Step-by-Step: Reverting from PTH Back to PTO Mode 25:09 – Manual Clutch-In of Main Engine (May Require Turning Gear) 26:42 – Final Steps: Switch Back to PTO Mode and Resume Normal ME Operation 🎥 No voiceovers. No scripts. Just raw, real-time walkthroughs with machine soundscapes and educational captions. 🔧 This is not a drill. This is actual emergency propulsion simulation on a 2020-built vessel. 🔖 Tags #ProbeLem #PRObed #ShaftGenerator #SyncFail #ShipBlackout #SeaTrial #DryDocking #PMS #PowerManagementSystem #MarineTroubleshooting #ElectricalDiagnostics #ShipAutomation #SATProgram #ElectricalEducation #ShipRepair #ProbeDD #marineengineering 📌 Want to support real-world videos like this? • Patreon –   / probelem   (Support Real-World Probing) • Facebook –   / your.probelem   • Join this channel to get access to perks:    / @probelem   ⚡ DISCLAIMER & DISCLOSURE All content shared on this channel is for educational and documentation purposes only.
