The paper gives a general description of the Concrete Gravity Base Structure (GBS) for the Draugen platform installed by Norwegian Contractors a.s. The GBS was installed at the Haltenbank area on the Norwegian continental shelf in May 1993 for A/S Norske Shell. Further, the paper describes the following challenging aspects encountered during the design and construction: design for high frequency response to wave loading, so called ringing, discovered during construction of the GBS; impact of the ringing effect discovery on the construction schedule; design to prevent delamination of concrete structural elements; modifications to prevent damages on pipe work caused by deformations of the concrete structure.
