Operating from Dublin Airport, Rescue 116 was on call 365 days a year, 24 hours a day.
Last year, they were awarded the Marine Ministerial Letter of Appreciation for Meritorious Service.
This award recognises outstanding acts of courage and heroism during emergency incidents.
Rescue 116 carried out 148 rescue missions in 2015.
This was the first year that search and rescue teams completed 1,000 missions in the Coast Guard's history.
The crew were involved in the rescue of a father and son after a helicopter crashed in a garden in the foothills of the Cooley mountains in Co Louth on Sunday.
The two men, named locally as Donnie and Dustin Marron, had to be cut from the Robinson R-44 Clipper after emergency services rushed to the scene.
They were transferred to hospital by Rescue 116.
In January 2017, Rescue 116 helped save five fishermen from a sinking trawler off the Dublin coast.
The 12m vessel was holed after drifting on to rocks just south of Balbriggan harbour in north Dublin and sank about three hours later.
They were also involved in the rescue of a man in his 70s from a north Dublin beach. He had been suffering from severe hypothermia.
Along with marine rescues, the Rescue 116 crew also helped transfer people who had fallen ill at aiports.
In 2016, they completed six medical rescues and assisted Rescue 117 with the transfer of a six-year-old girl and her mum from Kerry to London for an emergency liver transplant.
Over the years, the crew were also involved in a number of mountain rescues.
They came to the aid of a young boy who was reported missing in August last year.
He was rescued on the coast line at Greystones in Co Wicklow after he was spotted by a fisherman on the rocks at Bray Head.
