The Zawtika Project is a gas field development project located in the Gulf of Moattama, Myanmar. The development area covers Block M9 and small portion of Block M11, owned by Myanmar Oil & Gas Enterprise (MOGE). The field lies approximately 300 km south of Yangon and 290 km west of Tavoy on the Myanmar coast and the average water depth is approximately 120-160 meters.

Added Value

  • Nautec leverages on a long track-record of supply and installation of UHPC and other cementitious products for offshore installations, where offshore mixing, pumping and injection of UHPC materials into structures situated in both shallow and deep water has been the integral component of the project.
  • We currently operate seven offshore spreads with the flexibility of being fed by either silo or bulk bags. Depending on the feeding system, material, delivery distance and configuration of receiving structure, the spread rates vary from 4 to 15 m3 but can be increased by adding additional mixing and pumping modules.
  • The spreads operate with batch mixing systems as they guarantee high quality and consistency of the grout output yet they are still able to deliver high rates for high volume projects.
