Transportadora de Gas Natural de la Huasteca (TGNH) is developing the Southeast Extension Project (SEE) in Mexico. The maritime scope of the project consists of a 36-inch diameter pipeline from:
- Veracruz North to Coatzacoalcos, and from
- Coatzacoalcos to Dos Bocas

The pipeline is being developed to transport natural gas to several delivery points in the southeast region of Mexico. TGNH has awarded Allseas the contract for the marine construction of the pipelines for the Southeast Extension Project (SEE). Allseas has awarded the pre-commissioning work contract to Baker Hughes PPS and in turn Baker Hughes has contracted with an outside vendor (Posicionamientos Marinos Malaquias) to provide the subsea temperature monitoring service used during the hydrostatic test operation of the north and south pipelines.
At Posicionamientos Marinos Malaquias, we have been the only ones to provide the underwater temperature monitoring service used during the hydrostatic test operation of the north and south pipelines.
AMT Equipment
Multiple AMTs were installed along the pipeline to monitor subsea temperature during hydrostatic testing of the pipeline.
