The top side support 62 is raised by raising the hull 6 of the vessel 1 relative to the water surface 7.
The support structure 4 can subsequently be removed according to the invention, such as shown in the fig. 12-16.
10 This allows the vessel 1 to remove or install a sea platform comprising a support structure and top side in one trip.
It is also possible to remove or install a second top side 5, as for example shown in the fig. 1-11.
It will be apparent to those skilled in the art that various modifications can be made to 15 the vessel and method according to the invention without departing from the scope as defined in the claims.
