                                                                A combination of special designed steel cradles with tailor-
                                                              made wooden inlets serves as seafastening arrangement for
                                                              the MPs. The cradles are installed within a kind of plug and play
                                                              system. They are stowed between steel plates welded as stop-
                                                              pers and additional steel wedges fix them. Easy to install, easy to
                                                              remove.
                                                                Thus, when the vessel’s crew changes the cargo setting from
                                                              MPs to TPs, they can easily remove the steel cradles from the
                                                              hatch covers and the tween deck. So, the TPs can be secured
                                                              with extensive grillages on the tank top and MV Svenja sails with
                                                              open hatch.

                                                              with the cargo variety and facilitates a quick handling. More-
