10 Largest Hospital Ships In The World

What is a hospital ship?

A hospital ship is designed to be a floating hospital on the ocean or seas to offer medical treatment spanning from minor to major surgeries, prescribing medication, etc.

One may wonder when they were even invented and why. However, they are not a modern phenomenon, as they have existed since ancient times.

The navy of Athens had a ship called Therapia, and even the Roman Navy had a similar ship called Aesculapius. Their names and descriptions indicate they were hospital ships, providing comfort to the wounded and sick.

What is the need for Hospital Ships in the world?

Today, most hospital ships are operated by a country’s navy and used during peacetime and even during war, global emergencies, natural disasters, etc.

In developing nations, there is a shortage of medical providers, medical tools, and medicines needed for surgery and infrastructure. Secondly, some poor communities live in far-flung regions away from hospitals on the land and near the coast or shores. They lack access to basic medical care and attention and suffer since they lack money to get treatment.

In all these scenarios, hospital ships come to their rescue as they visit such people and give them timely treatment, almost free of cost.

Use of Hospital Ships during the World War Period

In the 19th century, old and obsolete warships were used as hospital ships to treat the soldiers. Hospital ships were used on a huge scale during the World War Period when several passenger liners, such as RMS Aquitania and HMHS Britannic, were converted to be used as floating hospitals.

The hospital ships look different from other ships as they are painted in white and carry a white flag with a red cross. Even their interiors, utensils and furniture are designed to give the feel that one is in a hospital on land.

The 2nd Geneva Convention prohibits any military attacks on these vessels; however, during World Wars, even hospital ships were targeted. For instance, Canada’s SS Letitia (i) and HMHS Llandovery Castle were sunk by a German boat, resulting in several deaths despite the status of the ships.

Let us explore the 10 largest hospital ships in this article.

1. MV Global Mercy

The world’s biggest civilian hospital ship, MV Global Mercy, was built as a floating medical centre for Mercy Ships. This humanitarian organisation operates the largest non-governmental hospital ships in the world.

It was constructed by CSSC at Tianjin Xingang Shipyard in Tianjin, China, and completed in 2021. The following year, she sailed to Rotterdam for a 2-week stopover, where it was revealed to the world for the first time. It made its maiden voyage soon after to Africa, where it was joined by another hospital ship called Africa Mercy. Global Mercy then began functioning as a floating training facility in Dakar, Senegal.

The vessel provides surgical care onboard and even undertakes land-based operations and mental health campaigns for the terminally ill. It has 28 vehicles that travel with the ship for its shore-based activities.

The operating rooms have everything required for specific surgeries required by people of a country that this ship visits.

Since it visits the poorest countries, ailments like hernias, tumours, burns, cataracts, childbirth injuries, etc, can become serious, and the people suffering from them are shunned from their communities. Hence, the doctors onboard treat them and gift them their normal lives back.

The hospital ships operated by navies of different countries, as well as several non-governmental organisations, are a testament to the commitment of these entities to offering medical care and humanitarian aid to the most needy across the world.

These floating hospitals are marvels of engineering and innovation. They are equipped with the most advanced equipment and need a lot of energy to function daily. Above all, they are the epitome of the dedication and compassion of healthcare workers, many of whom function on these ships voluntarily.

Hospital Ships can come in handy during emergencies, man-made and natural disasters, wars, etc and can even be used to house people for a short time in case such a situation arises.

The fact that there are so many hospital ships in the world which operate round the clock so that medical help reaches the poor and isolated communities across the globe shows the power of collective effort and cooperation.

As these floating hospitals sail the seas and oceans, they leave a legacy that spans beyond their decks. They are holders of countless memories and remain symbols of care and resilience in the communities that they serve.
