Vulkanwerft Hamburg: In Search of IMPERATOR’s Birthplace

From the Oder to the Elbe

My journey into Hamburg’s maritime world began with a ship that no longer exists.

On 6 June 2026, I encountered IMPERATOR at the Hamburg Port Museum.
Only a model remained: a long black hull, three yellow funnels and the great eagle that once spread its wings above the bow.

Behind the model were photographs of another world.
Steel frames rose across a crowded slipway.
Workers stood beneath a hull so immense that the shipyard itself seemed to disappear around it.

At the time, I knew little about the people who had built her.
I only knew that IMPERATOR had once been the largest passenger ship in the world.

She became the beginning of my beloved fleet.

Following her voyages led me into the history of Hamburg, transatlantic travel and the ships preserved along the Elbe.
Eventually, however, the story began to move backwards.

Before a ship can cross an ocean, someone must build her.
Before she receives a name, she must first take shape on land.

To find IMPERATOR’s birthplace, we must leave Hamburg for a moment and travel east to Stettin, now the Polish city of Szczecin.

There, beside the lower Oder, two engineers from Hamburg established a small iron shipyard in 1851.
The early yard was modest, with ships constructed in the open beside the river.
Yet it produced Prussia’s first iron seagoing vessel and gradually developed into the major industrial enterprise known as Stettiner Maschinenbau-AG “Vulcan.”

By the end of the nineteenth century, the ships were becoming larger.
The river leading from Stettin to the Baltic could no longer serve every vessel the company hoped to build.

The problem was not a lack of shipbuilding knowledge.
It was geography.

Large ocean liners required deeper water, direct access to international routes and close contact with the shipping companies that ordered them.
Hamburg offered all three.

In 1905, the Stettin company decided to establish a second shipyard in Hamburg.
Construction began in 1907 on Ross Island in Steinwerder, between the Rosshafen and the harbour later known as the Vulkanhafen.

The location placed the new yard directly beside the waters of the Elbe.
Ships could leave the slipway, enter the port and continue towards the North Sea.

In June 1909, Kaiser Wilhelm II attended the official opening.

The name Vulcan came from Vulcanus, the Roman god of fire and metalworking.
It was an appropriate name for a place where flames, hammers and human labour transformed steel into ships.

German sources use both Vulcanwerft and Vulkanwerft.
The company originally used the Latin spelling “Vulcan,” while the Germanised form “Vulkan” became increasingly common from around 1913.

The name changed slowly.

The scale of its ambition changed much faster.

The World’s Largest Passenger Ship

The new Hamburg yard had barely begun operating when it received the project that would define its history.

At the beginning of the twentieth century, German and British shipping companies were competing for the North Atlantic passenger trade.
The Hamburg-Amerikanische Packetfahrt-Actien-Gesellschaft, better known as HAPAG, wanted a liner that could challenge the great British ships in size, comfort and prestige.

The driving force behind the plan was HAPAG’s director general, Albert Ballin.

Ballin did not simply want another passenger ship.
He envisioned a floating city designed to represent Hamburg and Germany before an international public.

The new vessel was initially expected to carry the name EUROPA.
Kaiser Wilhelm II preferred a more commanding name.

She became IMPERATOR.

Her keel was laid at the Hamburg Vulkan yard on 18 June 1910.
She was only the third new ship begun at the young shipyard, yet she was already its most ambitious undertaking.

On one slipway stood a naval vessel.
On another, the frame of the future ocean liner began to rise.

Steel plates arrived at the yard.
Furnaces heated thousands of rivets.
Cranes lifted heavy sections of the hull while teams of workers hammered them into place.

Newspapers described a hollow iron body ringing like a bell beneath the blows of hundreds of hammers.

For the public, IMPERATOR represented national ambition and technological progress.
For the people building her, she was years of physical work carried out among fire, noise and steel.

On 23 May 1912, thousands gathered to watch her launch.

The unfinished hull began to move.
Supported only by the carefully prepared slipway, the enormous ship slid into the Elbe.

At her bow stood one of her most striking features: a bronze eagle with its wings spread above a globe.
The sculpture extended the ship’s overall length and turned her bow into a declaration of imperial confidence.

Yet launching was not completion.

During the following months, propulsion machinery, cabins and public rooms were installed.
Thousands of workers and craftspeople contributed to the final stage, including engineers, metalworkers, carpenters, decorators and specialists responsible for the ship’s elaborate interiors.

When completed, IMPERATOR had four propellers and a gross tonnage of more than 52,000.
Her restaurants, lounges, library and swimming pool belonged to the emerging idea of the ocean liner as a destination in itself.

The ship was delivered to HAPAG in April 1913.
On 11 June, she departed from Cuxhaven on her maiden voyage to New York.

With her entry into service, IMPERATOR became the largest passenger ship in the world.

Only four years had passed since the Hamburg yard officially opened.

For Vulkanwerft, she was more than a famous ship.
She proved that the new yard could construct a vessel at the highest level of international shipbuilding.

Other notable ships followed or stood beside her in the yard’s history, including FRIEDRICH DER GROSSE, CAP TRAFALGAR and CAP NORTE.

None, however, became as closely connected with the name Vulkanwerft as IMPERATOR.

She carried the yard to its highest point.

Then the world around the slipways changed.

When a Shipyard Loses Its Name

IMPERATOR entered service in 1913.

One year later, the First World War began.

The era of ambitious German transatlantic liners came to an abrupt halt.
The same shipbuilding knowledge that had produced a floating palace was redirected towards submarines, torpedo boats and other naval vessels.

The slipways remained busy.
The purpose of their work had changed.

After the war, military orders disappeared and the German shipbuilding industry entered a prolonged crisis.
Independent yards struggled to survive.
Companies merged, names changed and industrial sites passed into new hands.

In 1928, Vulkanwerft became part of Deutsche Schiff- und Maschinenbau AG, commonly known as Deschimag.

In 1930, the Hamburg site was taken over by Howaldtswerke.
It was later integrated with neighbouring facilities and developed into Howaldtswerke Hamburg.

The shipyard had not yet vanished from the landscape.
Its workshops and slipways continued to be used.

What disappeared first was its identity.

The word Vulkan slowly left the company signs.
The yard where IMPERATOR had been built remained physically present, but it no longer existed under the name that had made her.

This was the first form of disappearance.

The second came decades later.

In 1986, the site was sold to Blohm + Voss.
Shipbuilding there ended the following year.

The workshops fell silent.
The slipways ceased to receive new hulls.
The industrial world that had once employed thousands of workers withdrew from the harbour.

Today, the original Vulkanwerft can no longer be found on the Hamburg waterfront.

The name survives in Vulkanhafen, the harbour basin beside the former yard.
It remains on the map after the company, buildings and ships have largely disappeared.

IMPERATOR is gone as well.

After the First World War, she passed into British service and was renamed BERENGARIA.
Her later career belongs to another part of the story.
By the end of the 1930s, she too had been dismantled.

The child disappeared. The parent disappeared.

What remains are photographs, plans, models and a name beside the water.

When I first stood before the model of IMPERATOR, I thought I was looking at the history of one ship.
Only later did I understand that a ship also carries the history of the place that built her.

Her hull began on a slipway between the Rosshafen and the Vulkanhafen.
Her machinery reflected the engineering knowledge of her time.
Her scale revealed what Hamburg and HAPAG believed a modern ocean liner could become.

To remember IMPERATOR is therefore also to remember Vulkanwerft.

A ship may leave her birthplace and travel across the world.
Yet the body that carries her through every voyage is the work of the shipyard she left behind.

A ship carries an era’s imagination of distant worlds.
A shipyard gives that imagination a body capable of sailing.

Across Civilizations

King Kaolie recognised IMPERATOR.

“The last time you followed her,” he said,
“she was sailing towards the ocean.
Why have you returned to the land?”

“I wanted to know what came before the voyage,” I replied.
“I wanted to know who built her.”

Lord Chunshen Huang Xie considered this.

“A river gives a ship her route,” he said.
“A shipyard gives her a body.
By returning from the shipping lane to the slipway, you have found the beginning of her life.”

King Kaolie thought of the water gate at the ancient capital of Chu.

The ships of Chu have not survived.
Neither have the people who built them.
Only the rivers remain.

“So remembering a ship is not enough,” he said.
“We must also remember the people who made her.”

A ship does not appear by herself.
Nor does a distant world become reachable by itself.

Before every departure, someone must transform an idea into steel, machinery and a hull that can enter the water.

IMPERATOR once embodied Germany’s ambition to move outward across the sea.
Vulkanwerft gave that ambition a physical form and sent it into the Elbe.

From now on, whenever I encounter a ship, I will ask more than where she travelled.

I will also ask where she came from.

A ship carries an era’s imagination of the world beyond the horizon.
A shipyard makes that imagination seaworthy.
