ALE demonstrates innovation using floatover jacks to install one of the world’s longest linkspan bridges
ALE – Offshore Services has installed one of the world’s longest linkspan bridges using the innovative hydraulic floatover jacks in Gujarat, India.
Measuring 100m long and weighing 950t, the linkspan bridge needed to be installed onto the Dahej -Gogha Ro-Pax ferry using jacking, mooring and ballasting techniques.
This is the inaugural job for the hydraulic floatover jacks and were ideally suited to perform quick floatovers that can counterbalance the fast currents and the high tidal range of over 10m – within some of the highest variations in the world.
“This part of India witnesses massive tidal variations; in fact, some of the highest tidal variation in the world. Therefore, the operation required a timely and synchronised solution with little room for error,” explained Matthew Hodgson, Engineering Manager for ALE-Offshore Services.
