How we work in Mexico:

  • ALPHA DEEPWATER SERVICES S DE RL DE CV (ADS) is a corporation in the limitada format formed in 2009 to facilitate a contracting arrangement that would allow APS to market and deliver field development projects and other specialty advisory services to Pemex and other domestic or international participants in the Mexican oil and gas market. ADS is a company formed by APS and DTS (Deepwater Technology Services)
  • The ADS registered office is in Mexico City with local support services provided by Marcos y Asociados. The company assists with services related to the administration of the ADS Mexican contracts, management of translation services, accounting and invoice submission.
  • As required, ADS provide Mexican National personnel through a select number of Mexican employment agencies who work on behalf of ADS in Mexico.
  • ADS has gained extensive knowledge of the employment and tax regime requirements of both US and Mexican nationals working in Mexico since commencement of Mexican operations in 2009. This knowledge is valuable to foreign companies considering operations in Mexico, particularly if they must meet local content or cost recovery contractual requirements.
  • Where ADS has entertained a client’s requirement for non-US or non-Mexican personnel, we use our contacts in Mexico and their extensive background knowledge and experience in obtaining work visas.
  • ADS utilize the services of local agents to secure ‘port transit permits’, called “Autorización de embarque para técnico extranjero” often required by personnel who wish to travel to an offshore rig or facility using a crew boat.
  • ADS recently performed an extensive study of costs, employment practices, visa requirements, etc. for a US company planning to drill in Mexico. This covered the latest updates on employment contract administration, withholding and payment of Mexican income tax (ISR), social security (IMSS), housing allowance (Infonavit), termination and vacation pay.
