CHALLENGE:

To provide a solution for our client with a shore based winch solution for the Petronet LNG Terminal’s second jetty. 

There were several operational challenges to consider such as the hazardous environment, data transmission over 350m from the jetty control room to the winch systems, the limited area available and the 11m tidal variations. 

SOLUTION:

We project managed, designed, engineered and manufactured an 8-point 75 tonne constant tension mooring winch package to assist with this project. 

The comprehensive shore based winch package (SBW) comprising of eight 75 tonne single drum hydraulic mooring winches each complete with associated zone 1 hazardous area electric hydraulic power units, local control stations, remote control station, length and tension monitoring systems, four roller fairleads and synthetic mooring ropes.

Several unique features were integrated into the SBW package to compensate for a number of factors including the hazardous environment in which the equipment will be operational and the compact area of the mooring dolphins where the individual packages will be located.
