For the construction of a complex pipeline such as a Carbon Capture and Storage (CCS) pipeline, a clever vessel is required. Different approaches are possible for constructing different parts of such a pipeline, requiring their own set of equipment. It is up to the Naval Architect to design an efficient vessel lay-out that includes all the essential elements for an efficient approach. During the case you will be representing your own ship design department, who are being invited to tender (ITT) for an extensive offshore CCS pipeline construction project. The tendering process has already started, Allseas has informed the client that they are interested in the future construction project. However, the client replied that they need to know more about the method and vessel(s) that Allseas will be using before moving on to the next step. It’s up to you as Naval Architect to earn their trust by designing and explaining your reliable vessel lay-out and method that is suitable for construction of a CCS pipeline.
