The currently available foundation options capable of handling both ice and wave loads on offshore structures are very few. In most cases, even the few available design options create high wave and/or ice loadsIce load, of which they must be able to withstand. In addition, the construction and installation procedures of these foundations are challenging to undertake due to often high environmental loads, short weather windows, and limited accessibility. This Application CaseApplication Case (AC)within WP15 of the HOLISHIPHOLIstic optimisation of SHIP design and operation for lifecycle (EU H2020 project) (HOLISHIP) project refers to the conceptual design of an offshore foundation concept to manage both wave and ice loads in shallow watersShallow water with soft bottom seabed. Specifically, this chapter outlines the concept designConcept design, the structural analysisStructural analysis, and early project costCost estimates of the construction, transportation and on-site installation. The adopted approach is holistic by looking into all main issues of the platformPlatform design, of construction installation and life-cycle costLife Cycle Cost (LCC). The application area selected for this study is the Northeast Caspian SeaCaspian Sea. However, the concept is also well suited for other regions of the world with similar conditions. The concept can be used in hydrocarbon field development, bridge piers, oil piers (offshore loading facilities), wind turbine foundations, channel markers, lighthouse foundations, dolphins and harbour berth wall structures. In the concept development work, basic structural assessment and costCostestimation tools and models have been developed. They have been integrated into the HOLISHIPHOLIstic optimisation of SHIP design and operation for lifecycle (EU H2020 project) (HOLISHIP)concept designConcept designplatformPlatformbased on CAESESComputer Aided Engineering System Empowering Simulation by FRIENDSHIP SYSTEMS, Germany (CAESES)® enabling the iterative or optimisation designs in future feasibility studies.
