The vessel arrived in the White Continent on Thursday (18 November) after it departed from Puerto Williams in Chile on 10 November.
Silver Cloud then joined its fleetmate after it left Punta Arenas on 14 November.
The two vessels will sail Antarctica through March 2022, with several itineraries around the Antarctic Peninsula, the South Shetland Islands, South Georgia and the Falkland Islands.
Silversea is set to launch an Antarctica Bridge fly-cruise option on 11 December.
Roberto Martinoli, Silversea’s president and chief executive, said: "We are proud and excited to be at the forefront of the comeback of ultra-luxury expedition cruising in Antarctica.
"Accompanied by our seasoned team of expedition experts, our guests will not only be in awe of the authentic beauty and unique wildlife of the White Continent, but they will also enjoy the signature distinctions that have made Silversea the leader in luxury expedition cruising."
The line’s third ice-class ship, Silver Wind, has left dry dock at the Remontowa shipyard in Gdansk, Poland and will debut as an expedition ship in May 2022 in the Mediterranean.
