Guardian protects the offshore gas field near Taranaki by providing visibility of the platform infrastructure to tankers and supply ships on their navigation systems.


  • Maui Natural Gas field located in the Tasman Sea is 35km off the coast of Taranaki.
  • With tankers and supply ships actively operating between New Plymouth and the gas field, safety of crew and infrastructure was a top priority.
  • There was a risk that a vessel could collide with a platform or surrounding pipe infrastructure. This became very real when a large vessel drifted near a platform while dragging an anchor.


  • With a Goal Zero philosophy, which means no harm to people and protection for the environment, STOS employed Guardian:mark from Vesper Marine.
  • Virtual AIS buoys mark the gas platform for visibility to crew and supply ships.
  • Approaching vessels see the infrastructure on their electronic navigation systems while enabling STOS to monitor all vessels in the operational area.


  • With zero incidents, Guardian:mark has enabled Shell Todd Oil Services to maintain their safety record.
