LNG Mejillones

LNG Mejillones


Preliminary, Basic and Detail Engineering

Project Sheet:


GNL Mejillones S.A. required engineering services for the development of an EPC project for a new terminal for LNG unloading. 
The EPC contract for the marine works was awarded to BELFI S.A., and PRDW Aldunate Vasquez developed the project engineering. The proyect included a jetty for the reception of 2 LNG ships of 165,000 m3; one berth for LNG storage and processing (FSU vessel) and other berth shuttle unloading vessels. 
A FEED engineering was executed for the client, and the basic and detailed engineering for BELFI S.A..


The project considered the following: 
>  Accesstrestle 620 m long platforms including Lit, building electrical, etc.
>  Unloading platform with unloading arms, topside, and others. 
>  Mooring and breasting dolphins and gangways.
The engineering developed by PRDW-AV included: 
>  Layout definition. 
>  Study of local operational and design wave conditions. 
>  Study of operational downtime. 
>  Numerical modeling of ship at berth dynamics. 
>  Study and tsunami risk and penetration. 
>  Special seismic analysis.
