GCTC has successfully completed project (REPLACE PHOTOVOLTAIC SYSTEM FOR CATHODIC PROTECTION SK-65 AT SAFANIYA) with Saudi Aramco. The company did following works.
General Description of Work:
This project is intended to build new photovoltaic (PV) solar and battery storage system to supply power to existing SK-11 cathodic protection system for the pipeline corridor near Tanajib. The general sizing specifications are defined in the table below. CONTRACTOR may have the freedom to choose from two battery storage options as long as design temperature requirements are met.
CONTRACTOR shall be responsible to compensate auxiliary loads such as cooling system, shelter LED lights etc. with additional PV and battery storage capacity
CONTRACTOR shall ensure all materials related to the PV power supply system are designed and supplied in accordance with 17-SAMSS-12, including but not limited to
Batteries and Battery Racks
Overcurrent Protection Devices
Solar Charge Controller
Wiring and cabling
Passive or Active Cooled Battery Shelter
Battery Shelter Foundation
PV Modules Mounting systems
Project Scope of Work:
Overall Project Activity Summary:
Site Access Road Stabilization
Site Preparation Pre-Cast Concrete Works
Training of Aramco Staff
Pre Cast Installation
Shelter and PV Max Installation
Conduits, Trenching and cable pulling
Access Road preparation:
All Staff, Engineers and Labors who are suppose to work onsite must go through Safety Orientation training by Aramco. Three workshops were organized.
Allocating and fixing resources for the project and coordinating their transport from other area’s on the training day
Site preparation activities where needed prior to the installation of the Pre-cast concrete and that is due to sand accumulation
Site Soil Replacement, stabilization, surveying, foundation marking and levelling.
Pre-Cast Concrete Works:
Parallel to site preparation activities; Concrete Pre Cast work (5 blocks for the PV Max support, 4 footings and a slab for the batteries and EXERON Shelter) started at GCTC workshop in Aoyon (Al Hassa)
Material Delivery (Plywood and steel), Formwork, Steel Bending and Fixing, Concrete Pouring, Curing, Painting, Transportation and Installation
Shelter Preparation Installation of Protection Shields and Equipment
