Tronds Marine Service AS has over the past decades gained extensive experience in semi-submersible barge operations through the successful operation of “Tronds Barge 33”, which was a key asset in the construction and launching of caissons for the Port of Nador in Marocco and is currently on charter in Italy for the construction of the new Genova Breakwater. Additionally, “Tronds Barge 30” continues to play an active role in complex launching operations across Europe.
“The addition of this Newbuild to our fleet further strengthens our position as one of the leading operators of semi-submersible heavy cargo barges,” says Kjartan Mehammer, CEO of Tronds Marine Service. “This expansion enhances our capabilities and reaffirms our commitment to delivering reliable, high-quality solutions to our clients.”
