How can you be sure that a hazardous cargo is not put at risk when moored at your dock? Facilities of LNG Terminals need to be of the highest safety standards otherwise ship and terminal can be at the mercy of tide, weather and current during critical gas discharge operations.
Swift reaction to dangerous conditions, with appropriate warning alerts and automated / remotely operated mooring systems, can mean the difference between catastrophe and a minor interruption in offloading.
Optimum safety with efficient performance is why advanced TMS mooring technology was fitted at the new Escobar LNG terminal, on the river Parana des las Palmas, 40 km /25 miles north of Buenos Aires, Argentina. The Trelleborg Quick Release Hook (QRH) systems on triple and quadruple capstans, installed as recommended by SIGTTO, OCIMF and the IMO, enable safe release of each mooring line without manual intervention, even when under tension.
The QRHs are supplemented are enhanced by the Trelleborg Electric Release system, allowing remote operation in an emergency or when a vessel is leaving the berth. Protected by a four-way redundancy system, operation can be from a control room – button or screen operated, on the quay side from an actuator box or via a manual release on the hook; a fail-safe prevents unauthorized remote release.
The Trelleborg SmartHookÂ® load monitoring system integrates the safety of mooring conditions with individual line tensions in real time, providing onscreen control room warning, and a jetty-based high intensity light and siren. Load tension data also feeds into the jetty data bank, for essential safety and efficiency feedback. High technology mooring systems also help fulfill the requirements of marine insurance.
