Imagine having enough money to turn an offshore vessel into a giant expedition yacht that is twice the size of Jeff Bezos and Mark Zuckerberg’s support ships combined.
That is what a mystery billionaire has quietly been doing, with his offshore support vessel slowly becoming the expedition ship of dreams with extensive modifications.
Currently located in Bremerhaven, Germany, the vessel, known as L Symphony, has slowly undergone conversion into a luxury ship that can be used for exhibitions.
Not only has it undergone external changes, but internally, the vessel is vastly different from what it was before.
What has changed with the former offshore vessel?
The first thing we notice is the exterior of the L Symphony.
Gone is the red hull and working-style exterior.
Now, the ship is in a clean white livery, creating a much sleeker and pleasing display.
BOAT International was able to spy the vessel undergoing its refit.
Behind the bridge, we can see multiple new deck sections added to the existing ones.
In the aft section, a new helideck has been built to accommodate a helicopter.
But keeping with the exploration theme, the ship has kept the heavy-duty crane that it originally came with.

All of this should see the weight go up from 3,921 gross tonnes to 5,000.
What the conversion has done is add new luxury onto an already impressive platform.
It is believed the private owner of the ship bought it back in October 2023.
This is what the new expedition yacht will be used for
Originally called ASL Symphony, the ship was also called Energy Lindesnes when it was an offshore tug.
Full details as to the interior and fittings have been kept a secret.
In fact, details regarding the future plans for the vessel have also been kept highly private.
Images of the yacht have also been hard to come by.
It is only recently that a couple of photos of the ship in its new white livery were leaked out.

Further outfitting work is expected on the yacht in Bremen, ahead of a launch later in 2026.
The ship is highly likely to retain the same diesel-electric engines it had as an offshore tug.
This is one of the most curious conversions of a ship we have seen.
It will be interesting to see how this expedition yacht develops as 2026 progresses.
