Tillberg Design of Sweden (TDoS) has established a new parent company named Viken Group, which will provide a range of comprehensive design, naval architecture and project management services for the maritime industry.

Viken Group has acquired Italian designer and naval architecture firm Thalia Marine, which will assist in technical project management, surveys and consultancy.

Thalia Marine is based in Trieste, Italy, and has clients including Carnival Cruise Line, Silversea Cruises, Swan Hellenic, Virgin Voyages, Shanghai Merchant Ship Design and Research Institute, and Fincantieri.

“We are delighted to welcome Thalia Marine and its employees to Viken Group,” said Stefan Nilsson, CEO of Viken Group. “Together, we will be able to provide our clients the best, most comprehensive services including naval architecture, design, quantity surveying, technical consultancy, on-site inspections and much more.”

TDoS and Thalia Marine will continue to operate independently from one another but will collaborate under the Viken Group umbrella for certain projects.

“My connection with TDoS dates back to 1994, when, as a junior naval architect, I worked with them on the design of Costa Victoria,” said Maurizio Eliseo, CEO and partner of Thalia Marine. “Since then, we have cooperated on many challenging projects and achieved excellent results. Thalia is a small family, but one of highly specialised architects, engineers and surveyors. Thanks to this strong partnership with our dear friends at TDoS and Viken Group, we now look forward to an even brighter future that will not only benefit us, but our esteemed clients as well.”

Madelene Hall, CEO of TDoS, said: “The creation of Viken Group will greatly benefit TDoS and our clients. We will continue to focus on our core business, which is design, while being able to offer our clients a full-service concept through acquisitions and partnerships in Viken Group.”
