Strategy: 10 Implemented measures

1) Flaring instead of venting in LNG plants and UGS & send outcompressors.2) Replacing wet seals by dry seals in compressors3) Hot taps for in-service pipeline connections4) Composite wrap for non-leaking pipeline defects5) Electric motor starters in compressors & moto-compressors6) Electrical driven chemical plants

7) Convert gas pneumatic controls intoinstrumented air controls.8) Eliminate unnecessary equipment and/orsystems: avoiding obsolescence programe.9) LDAR for fugitive emissions (LDSext).10) Cost effective energy management.

2016: Enagas and Sensia set up Vira.

Founded in July 2016, but with an investigation and research process of more than 3 years behind.

Enagás is the leading Company in transport an LNG infrastructures in Europe and the TSO within the Spanish market.

Sensia Solutions S.L. is an expert in infrared gas imaging, with the academic support of the Infrared Lab (LIR) of the University Charles III (Madrid)

First sale order has been done by Enagas. This 3 first cameras will be ready for shipment in December 2016.

Cameras are tested in Enagás´ infrastructures, in real operational conditions.

Enagás Innovation and Development Centre in Zaragoza hosts the test center.

Background know-how and knowledge sharing process between stakeholders .

Minority Shareholders are represented by employees of Enagas that impulse the start up project and technology development.

Vira has performed a prudent Business Plan with sustained growth.

Commercial agreement with partnership on going and ready for early 2017.

IR cameras solutions (OGI) are recognized as the best technical and economical option for methane emissions detection system.

International Boards advise to used infrared imaging cameras to LDAR (Leak, Detect an Repair) activities.

The main benefits are:• Quick detection (thermographic source)• Image and sound frames.• Event localization and ROI limits.• Reduction of time in gas leak process

Vira’s objective is to provide SMART infrared Gas imaging solutions (OGI) that can easily detect and identify fugitive gas emissions in order to improve the energy and overall efficiency of the chemical, oil & gas, utilities.

Taylor made SW solution: Fitness for purpose

Intuitive reporting and GPS location.

Enagás is collaborating in the promotion of VIRA gas imagers in worldwide tradeshows, gas congresses, environmental agencies, etc. and among its international partners.

ISO 9001, 2015, compliance.

Roadmap: Convergence into SMART OGI

• Isotherms• Image saving• Analysis of images on memory• Creating and editing video• Gas processing• Wifi, bluetooh and Inthernet 4.0

19

• Certify with CE/USA marking.• Certify with IP & NEMA marking.• Certify accuracy under ISO 17015• Uses according to UNE-EN 15446• Uses according to EPA 21 final rule.• ISO 9001 compliance.

Vira’s final objective is to provide infrared gas imaging solutions (SMART OPTICAL GAS IMAGING, SOGI) that can easily DETECT and identify & QUANTIFY fugitive gas emissions in order to improve the energy and overall efficiency of the chemical, oil & gas, utilities as well as reduce dramatically the fugitive gas emissions according LDAR normative promulgation.

Technological goals achieved (2016):• Spatial ROI• Temporal ROI• Temperature calibration• Color Palettes• Temperature calibration• FFp reports and DB in the cloud

Technological goals to be achieved:
