Problem is that you don't have a tabsetPanel in your UI (which should be the parent of the two tabPanel). Right now you are using updateTabsetPanel, but the target is navbarPage.

Working solution below. There were two problems: navbarPage needs an id, and also there was an extra space in server.R selected (between Binning and input`

ui.R

library(shiny)
shinyUI(fluidPage(

    titlePanel("SCORE CARD DEVELOPMENT PLATFORM"),
    navbarPage("ScoreDevApp",
               tabPanel("Settings",
                        fluidRow(column(2,
                                        actionButton("goButton_service", "Load   saved parameters",width=200)
                        )
                        )
               ),
               tabPanel("Download & Binning input data"),
               id="ScoreDevApp"
    )
)
)

server.R

library(shiny)

shinyServer(function(input, output, session) {
    #load saved parameters 
    observeEvent(input$goButton_service, {
        updateNavbarPage(session, "ScoreDevApp", selected = "Download & Binning input data")
    })  
})
