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.

Production of an as-built drawing for VINCI Environnement

VINCI Environnement has entrusted TVA Engineering with the production of an “As-Built Drawing” for the electricity section of its energy recovery centre in Cornwall, England.

The CERC is able to recover up to 240,000 tons of non-recyclable residual waste per year, enabling the generation of 184,000 MWh of energy per year. Completed in January 2016, the CERC spans more than 15,000 m².

Work was carried out on site at the end of 2017, enabling the cabinet wiring diagrams to be updated in the engineering and design department. This work will soon be expanded to include new readings on site in order to suggest recommendations for optimization of the components of the electrical cabinets and lighting system.

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 Engineering continues its work with Perenco in Gabon

At the end of last year, one of our existing clients, Perenco, commissioned us to carry out detailed electricity studies related to the use of Gabon East OroVinyare’s offshore zone, which Perenco acquired rights to in 2012.

Perenco operates nine oil fields in Gabon, six offshore and three onshore, which makes the Franco-British operator Gabon’s top oil producer in Gabon, producing almost 100,000 barrels a day.

This initiative reflects Perenco’s ongoing desire to work with TVA Engineering, despite the currently uncertain climate in the oil and gas industry.

The ONAL power station enters the reliability phase

On behalf of Maurel & Prom, TVA Engineering carried out the “construction and fit-out” studies for its project to increase electricity production at the ONAL power plant in Ezanga, Gabon.

These studies were completed in July 2017 and TVA Engineering was then entrusted with completion of commissioning operations, setting up a dozen contractors at the site.

After more than four months of commissioning and tests, Maurel & Prom’s new plant began production on 3 December 2017 and is currently in the reliability phase.

Congratulations Nicolas Hochard!

Nicolas Hochard, diplôme d'Ingénieur Systèmes Électriques EPRM – Électronique de Puissance Réseaux et Motorisation au CNAM, TVA EngineeringWe would especially like to congratulate Nicolas Hochard for his diploma in Electrical Power Systems Engineering EPRM – Network Power Electronics and Motorisation, with distinction, on 28 September 2017.

You may already know that this training course is registered with the RNCP, (the French Directory of Professional Certification), and dispensed by the CNAM (the French Conservatory of Arts and Crafts), in partnership with the school “Arts and Crafts ParisTech”. The aim is to “train engineers capable of designing and implementing electric technology for tomorrow, in response to major developments in energy production, transport and consumption, while integrating environmental  and energy efficiency”.

Remember that Nicolas joined TVA Engineering on 22 September 2014 as an apprentice engineer. Despite many upheavals encountered by the firm during this period, Nicolas managed to adapt by absorbing as much of his tutors’ experience as possible and thereby acquiring the level of design studio electrical engineer. We are delighted today to extend our congratulations for his latest promotion to Electrics Engineer on 25 September 2017, after three years’ training. We hope he enjoys a long career with TVA Engineering.

Nicolas is a shining example of smooth integration, demonstrating once again that TVA Engineering has the capacity to train staff in its core lines of business: electricity, instrumentation, controls, automation, general installations and pipe fittings. We hope that this experience will continue to set an example in the near future. Because this is another facet of the “TVA spirit”!

Maurel & Prom renew their confidence in TVA Group

Arnaud Lahutte, Manager of the Engineering Division of TVA Group, Jean-François Hénin, Chairman of the Board of Directors of Maurel & Prom, and Antoine Tran Van, Managing Director of TVA Group. Arnaud Lahutte, Manager of the Engineering Division of TVA Group, Jean-François Hénin, Chairman of the Board of Directors of Maurel & Prom, and Antoine Tran Van, Managing Director of TVA Group.

Mr Jean-François Hénin, Chairman of the Board of Directors of Maurel & Prom, visited us on the 4th of October. The presence of Mr Hénin was notably the occasion to discuss the future of the operation of the ONAL site in Gabon.

Maurel & Prom has decided to contract with us for the studies regarding phase V whose aim is to increase electrical generation from 4 to 10.6 MW.

The recent acquisition by the National Indonesian oil company, Pertamina, of a bit less than 25% of the capital of Maurel & Prom, does not imply therefore, a decrease in our activity. Quite the reverse.
