Vertical ShoreTension® system
The Vertical ShoreTension (“VST”) dynamic mooring system utilizes the same ShoreTension® dampening technology as the proven Horizontal ShoreTension dynamic mooring system that is currently successfully operational at over 42 locations worldwide with well over 300 systems.
- Green solution
- Efficient
- Sustainable operations
Vertical secured
ShoreTension dynamic mooring systems maintain constant tension setpoints on its mooring lines and significantly reduce vessel movements in challenging conditions involving strong winds, currents, swell and passing vessels. Reducing vessel movements provides safer mooring with reduced danger of mooring line snapback, shortens turnaround time by allowing for faster uninterrupted loading/unloading operations in challenging conditions and increases berth availability.
Vessel motion reduction up to 90%
Shortens turnaroud time
No need of external energy
Worldwide monitoring
Certified
All ShoreTension systems have been certified by Lloyd’s Register in London and are available in hazardous area classification (ATEX/IECEx) versions.
The VST system offers solutions to port terminals with limited quay or dolphin space. While the Horizontal ShoreTension system requires a certain size of quay and 2 available anchor points, the VST system’s footprint is suitable to be installed at mooring dolphins.
Capacity
Furthermore, the VST system has a tensile capacity of 100 t, a quick release system, a rope slip system and a semi-automated rotating bollard that completely eliminates manual mooring line handling to adjust for changes in extreme tide and vessel ballast.
The onboard hydraulic power unit of the VST system is another unique feature that simplifies its operation. Once the VST system is installed no additional external electric power is required to operate the VST system. Operation of the VST system uses a push-button local control panel with digital visualizations of both the local VST system and all VST systems on the berth.
Design
The high-level of automation incorporated into the design of the VST system allows for faster dynamic mooring system training and operational competency of port terminal personnel, increases operator safety and allows ShoreTension personnel to remotely monitor all VST system digital and analog datapoints in real-time to advise port terminal personnel on VST system optimization.
The first VST system was installed in March 2022 and is currently operational at an LNG exposed port terminal in South America and has significantly increased berth availability, decreased turnaround time, reduced vessel motions, reduced wear on port terminal berth components and increased mooring safety for personnel.
