Irish navy ship the L.É. William Butler Yeats, which has been operating as a Covid-19 testing centre at Sir John Rogersons Quay, is returning to sea.
The Naval Service has been operating a community testing facility at the site since the middle of March.
The army is now taking over, with a test centre at the Aviva Stadium.
The navy has acted in support of the HSE in Dublin, Galway and Cork since the 15th of March as part of Operation Fortitude.
Over the last nine weeks, Naval Service Ships have supported the HSE and the National Ambulance Service in conducting almost 6,000 Covid-19 Tests.
