The Unexpected Freeze of Your Critical Navigation System Imagine being in the middle of a crucial drilling operation when suddenly, all three of your state-of-the-art DP system gyros fail. That’s exactly what happened during a recent drilling venture—within just five minutes, the gyros, essential for maintaining your vessel’s heading, froze, leaving the drillship’s DP model…
The Thrill of the Unknown Imagine being on a DP2 supply vessel, perfectly poised outside a gas platform’s 500m safety zone, when an unexpected twist of fate strikes. Your engineers, in the midst of routine checks, accidentally trigger an emergency stop. Instantly, the lights go out. The vessel, once a stalwart guardian against the elements,…
Overview So, picture this: You’re in the North Sea, confidently conducting ROV operations, and everything is going swimmingly—until it’s not. Suddenly, alarms start blaring for your DGNSS systems like they’re auditioning for a horror movie. DGNSS 2 and 3 drop out of the DP control, followed by DGNSS 1 and 4 and Gyro’s 1 and…
Overview In the high-stakes environment of deep-sea diving operations, maintaining precise positioning is critical. When a diving vessel relies on multiple Position Reference Systems (PRSs) for dynamic positioning (DP), any drift or miscalibration can lead to significant challenges. In a recent scenario, two High Precision Reference (HPR) systems began drifting, while the Differential Global Navigation…
🚢 Don’t Just Be There – Be Effectively There! Discover DP Equipment! 🚢 In the high-stakes world of offshore operations, the pressure is on.Are you navigating through stormy seas with unreliable positioning systems? Imagine this:🌊 28 knots of wind🌊 3.2-meter swells🌊 Alarm bells ringing as your vessel drifts away… You need precision. You need reliability….
🌊 Protect Your Vessel with Critical Alert 🌊 Avoid Critical Situations!Don’t let a Power Management System (PMS) malfunction put your vessel at risk. Overview Imagine you’re aboard a vessel, navigating through treacherous waters when suddenly, the Power Management System (PMS) fails due to a fault in the Input/Output (I/O) module of the No. 4 center…
Overview This case study analyzes a DP incident on a class 2 MODU during well intervention operations. The unit was in open bus mode, with all four thrusters active and four out of the six generators connected, two on each side. What occurred? Engineers requested the DPOs to deselect and stop Thruster No.1 from the…
Overview On an FPSO, the DP event took place. Although the FPSO has two stern azimuth thrusters and a bow tunnel thruster, the bow thruster was turned off for continuous diving operations during the event, and the starboard aft thruster was not in use because of upgrades. From a light diving craft (LDC), diving was…
A comprehensive review has been carried out to assess incidents that jeopardize DP operations, derive valuable lessons, and prevent future dangerous occurrences. These case studies are sourced from the IMCA DP Event Bulletin. Overview A DP equipment class 2 PSV was operating in open bus mode with all engines and thrusters engaged. The vessel conducted…
