The S.A. AGULHAS II represents the latest chapter in South Africa’s long Antarctic and Southern Ocean tradition. From the R.S.A. and S.A. AGULHAS to modern polar research, Endurance22 and her 2026 Marion Island deployment, her story connects Cape Town with some of the world’s most remote scientific environments.
Continuing South Africa’s Antarctic and Southern Ocean Legacy
S.A. AGULHAS II (IMO: 9577135)
For the moment, the South African polar research and supply vessel is at rest, anchored off the Cape Town coastline. But the apparent stillness of the ship conceals a very active history — one extending from the early years of South Africa's Antarctic programme through decades of Antarctic and sub-Antarctic logistics, scientific research and exploration.
The vessel photographed today is therefore not simply another large ship in Table Bay. She represents the latest stage of a South African maritime and scientific tradition that stretches back more than six decades.
From R.S.A. to S.A. AGULHAS
South Africa's Antarctic programme developed rapidly during the years following the establishment of its permanent presence on the continent. The first South African National Antarctic Expedition departed in 1959, and the country subsequently developed its own logistical capability for supporting personnel and scientific operations in Antarctica and on the sub-Antarctic islands.
Among the vessels associated with those early operations was the R.S.A., followed in 1978 by the S.A. AGULHAS. The latter was built in Japan and became South Africa's principal polar supply and research vessel for more than three decades.
The S.A. AGULHAS carried personnel and supplies to the Antarctic station at SANAE IV and supported South African operations on Marion and Gough Islands. She also undertook scientific work in the Southern Ocean, making her part of a developing system in which logistical support and scientific research increasingly operated together.
By the time she was replaced in 2012, the S.A. AGULHAS had become an established part of South Africa's polar identity. Her successor would retain that legacy, but with a considerably expanded set of capabilities.
The arrival of S.A. AGULHAS II
The S.A. AGULHAS II was constructed in Finland and formally handed over to South Africa in April 2012. She arrived in Cape Town on 3 May 2012. At 134.2 metres in length, she was substantially larger and more capable than her predecessor, having been designed specifically as both a polar research vessel and a logistical support platform.
The distinction is important.
Rather than being simply a replacement supply ship, S.A. AGULHAS II was conceived as a multi-purpose scientific and operational vessel. Her ice-capable design, laboratories, cargo facilities, helicopter capability and accommodation allow scientists, engineers, technicians and support personnel to work together during extended voyages into some of the most remote maritime environments on Earth.
Her early operational history demonstrated the breadth of this role. Research voyages were combined with relief and resupply operations to Marion and Gough Islands and with the annual Antarctic relief programme. Scientific measurements could continue while the vessel was simultaneously performing the practical work required to keep South Africa's remote stations operational.
This combination has remained central to the vessel's identity.

A ship for science as well as logistics
The Southern Ocean is one of the world's great environmental systems. Its currents connect the Atlantic, Indian and Pacific Oceans, while its interaction with Antarctica, sea ice and the atmosphere has consequences far beyond the polar region.
Consequently, the work undertaken from S.A. AGULHAS II is not confined to Antarctica itself. Oceanographic, atmospheric, biological and environmental research conducted during voyages contributes to a wider understanding of climate, ocean circulation, marine ecosystems and the changing relationship between the Southern Ocean and the rest of the planet. SANAP describes the Southern Ocean as critical to understanding Earth's water systems and its influence on global climate and rainfall patterns.
The vessel has consequently become a floating laboratory, transport platform and logistical base — capable of carrying people and equipment into remote regions while providing the infrastructure required for sophisticated scientific work.

The Endurance connection
The international profile of S.A. AGULHAS II was dramatically increased by her involvement in the search for Sir Ernest Shackleton's lost ship, Endurance.
In 2019, the vessel supported the Weddell Sea Expedition, which reached the region where Endurance had sunk but ultimately had to abandon the search after severe weather, deteriorating sea-ice conditions and the loss of an autonomous underwater vehicle. The expedition nevertheless completed a major programme of scientific research in the Larsen C region.
Three years later, the renewed Endurance22 expedition succeeded where the earlier search had failed. On 5 March 2022, the wreck of Endurance was located on the seabed of the Weddell Sea.
The achievement was historically remarkable, but it also demonstrated something significant about S.A. AGULHAS II: the vessel had evolved into a platform capable of supporting highly sophisticated modern exploration in an environment that had defeated many earlier generations of explorers.
The discovery of Endurance therefore sits naturally within her broader history of polar science and exploration.

Returning to Marion Island
Her latest deployment provides another, very different, example of her importance.
In 2026, S.A. AGULHAS II was called upon to support the reactivation of South Africa's Marion Island research base following the evacuation of the previous overwintering team earlier in the year.
The vessel departed Cape Town on 5 August 2026 and arrived at Marion Island on 9 August. The mission involved personnel from several South African institutions and included a substantial logistical operation to restore the base to working order. A 32-member team, including 20 personnel from the Department of Public Works and Infrastructure, was deployed to undertake reactivation and repair work. Equipment, supplies and fuel were transferred from the vessel to the island, including 494 tonnes of cargo and approximately 300 tonnes of polar diesel.
The significance of the voyage went beyond routine resupply.
By late August, the Marion Island base had been successfully handed over to the new M83 overwintering team, allowing South Africa's long-term scientific and environmental observation programme to resume. The S.A. AGULHAS II then began the return voyage to Cape Town, where she was expected to arrive on 4 September.
It is from this latest mission that the vessel has now returned to Table Bay.
A continuing South African presence
The Marion Island operation illustrates the less spectacular but perhaps more fundamental role of S.A. AGULHAS II.
The Endurance discovery was an extraordinary international event. It captured worldwide attention because it connected a modern South African research vessel with one of the great stories of Antarctic exploration.
But much of the vessel's real importance lies elsewhere — in the regular movement of people, equipment, fuel and scientific infrastructure between Cape Town and the remote stations and islands for which South Africa remains responsible.
The voyage schedule reflects this continuing pattern. S.A. AGULHAS II undertakes Antarctic relief voyages, Marion Island operations, scientific cruises and voyages associated with Gough Island and other Southern Ocean research programmes.
The vessel is therefore part of a continuous cycle: Cape Town, the Southern Ocean, Antarctica or the sub-Antarctic islands, and eventually Cape Town again.
A ship photographed at home
Seen from the Cape Town coast, that wider story can be easy to overlook.
A large red-and-white research vessel anchored offshore can appear remarkably static. Yet the ship's presence in Table Bay is temporary. Her operational life is defined by movement — southward into increasingly remote waters and then back to the city that serves as her logistical and institutional home.
The R.S.A. began this modern era of South African polar logistics. The S.A. AGULHAS carried it forward for more than three decades. The S.A. AGULHAS II has inherited that responsibility while transforming it into something broader: a platform for Antarctic logistics, Southern Ocean science, environmental observation, education, exploration and international scientific collaboration.
That continuity is perhaps the most interesting thing about the vessel.
She is not merely a replacement for an older ship. She is the latest expression of a national programme that has adapted as the demands of polar science have changed.
And so, photographed from Cape Town after her latest return from Marion Island, S.A. AGULHAS II can be seen in two ways.
She is a ship at anchor.
But she is also a visible link between Cape Town and the Southern Ocean — between the history of South Africa's Antarctic programme and its continuing scientific future.
For now, she rests in Table Bay.
Soon, another voyage will begin.
