The COE project consisted in the expansion of the Chavyo On-shore processing facilities, in the framework of the Sakhalin 1 project. A first phase of the Project took place in 2005.

The activity carried out by Trillini Engineering was divided into 2 main parts:

The engineering, procurement and prefabrication of two buildings, namely the Local Equipment Room and the Power Generation Building;
The support to the in situ installation of the engineered materials, purchased by the main contractor in the first phase of the project.
Here follows a in-detail description of the activities:

LER – Local Equipment Room

• Basic design of HVAC system, of the electrical rooms, of the prefabricated container designed to accommodate the switchgear and the instrumentation for a future gas turbine installation;
• Coordination of the interfacing between the various vendors during the prefabrication phase;
• DCS + SIS – Distributed Control System;
• UPS – Uninterruptible Power Supply;
• Quadri elettrici MV-LV;
• ECS – Electrical Control System;
• Turbine;
• Support for the testing and start-up activities of the HVAC and of the electro-instrumental systems, manufactured‚ in Italy, in Franzisella – Casciago (VA).

PGB – Power Generation Building
