2011年10月13日，大會秘書組收到TEC執行總裁、隧道和地下工程首席專家漢斯•德 維特（荷蘭）的確認函，他確定在研討會主題報告：“丹麥至德國費蒙貝爾特海底沉管隧道案例分析  ”。

    The Fehmarnbelt Fixed Link will be the third major fixed link in the Danish Road Network and will serve as a direct road and rail connection between Scandinavia and continental Europe. The Fehmarnbelt Fixed Link will specifically connect Rødbyhavn in Denmark to Puttgarden in Germany and is expected to bring economic benefits to the entire region around the Fehmarnbelt.

    In a feasibility study carried out in the nineties of last century the cable stayed bridge was selected as preferred option for this approx. 20 km long fixed link. The immersed tunnel option was identified as the best alternative.

    From 2009 the selected bridge and tunnel option were investigated and compared in more detail in a true a design competition. These designs are undertaken by separate groups of consultants commissioned by the state owned organization Femern A/S.

    The immersed tunnel option design was assigned to the RAT JV, comprising TEC, Arup and Rambøll. After a design period of approximately 2 years the JV submitted a state of the art immersed tunnel design. In February 2011 the immersed tunnel option was selected by the Client as the preferred option to realize the fixed link between Germany and Denmark.

    The presentation will focus on the innovative design approaches that finally resulted in the selection of the immersed tunnel.

    Hans de Wit has graduated from the Eindhoven University of Technology, Structural Design and Engineering in 1986. During his career he was involved in various major bridge and tunnel projects. He is one of the most experienced TEC immersed tunnel designers and has held the position of specialist advisor, project manager and design leader in many (immersed) tunnel projects, including the specific execution aspects of immersed tunnels. He is also the current TEC managing director.

    Currently he is involved as Specialist Advisor in the North/South Metro Line in Amsterdam (including immersed tunnels), the Fehmernbelt Fixed Link, the Hongkong Zhuhai Macao Bridge Link and recently in the Shenzhong Crossing.
