EPC entrusted by SARA : a success

TVA Engineering was contracted by SARA (Société Anonyme de la Raffinerie des Antilles) in Martinique for two EPC (Engineering, Procurement, Construction) :

  • Adaptation of a hydrogen cell for connection to the SARA electrical grid,
  • Replacement of the main High-Voltage switchgear for Electrical Substation n°1.

SARA acquired a hydrogen cell. Before installing it definitively on its oil depot in Guyana, SARA wanted to test this equipment on its electrical network at the Martinique Refinery.

As part of this contract, TVA Engineering has specified, supplied and installed two specific transformers and two high voltage electrical cubicles.

Installation work was carried out between November and December 2017, for operational tests on the SARA electrical network in January 2018. The tests were compliant.

Following this success, SARA decided to supply a new hydrogen cell.

The Substation 1 High-Voltage switchgear existed since the seventies and was getting obsolete. TVA Engineering’s mission was to specify, supply and install a new switchgear.

Work began in October 2017 and the first part of the switchgear was commissioned in December 2017.

During this timeframe, TVA Engineering highlighted the risks of the refinery’s production shutdown due to the electricity grid management.

SARA therefore decided to wait until the 2018 Shutdown to replace the second and last part of this switchgear under the best conditions.

This switchgear, essential for the production of SARA, was put into service and delivered to operation on March 23rd, 2018, before the end of the scheduled shutdown.

TVA Engineering also provided operating training to SARA agents for the new switchgear.

During these two operations, TVA Engineering demonstrated its rigor and ability to meet deadlines, while ensuring flexibility appreciated by the client.

Work continues on the SARA EPC

Last October, we began work to replace the main high-voltage switchgear for substation 1 of the SARA (Société Anonyme de Raffinerie des Antilles) in Martinique.

This replacement is being carried out live, with the station’s dependent units continuing to operate during the works. So far, the first part of the board has been installed and powered up. The works are scheduled for completion in the first quarter of 2018.

The SARA is 71% owned by the company Rubis and owns a refinery in Martinique, as well as hydrocarbon depots in Jarry, Guadeloupe, and Kourou and Dégrad des Cannes in French Guiana.

TVA wins an EPC contract from SARA Martinique

After FOXTROT who recently awarded us an EPC contract for the supply of a Black-Start unit, it is the turn of SARA to place its confidence in us for a new EPC.

 The company SARA (Société Anonyme de Raffinerie des Antilles), which TVA has worked with for more than ten years, has awarded us the contract for revamping the High Voltage (5.5 kV) switchgear. Installed in sub-station no. 1, it supplies the electrical consumers of its refinery situated in Lamentin, Martinique.

 The new switchgear shall be comprised of 14 French-made, Schneider brand MCset reference cells. It will also be equipped with SEPAM digital protection relays. Acceptance of the installations shall take place at the end of October 2017.
