I'm not sure what you mean Henk. P&O Nedlloyd was itself an amalgamation of P&O and the Nedlloyd Group until bought outright by AP Moller-Maersk several years ago. The P&O Nedlloyd brand was completely dropped and all P&O Nedlloyd-named ships were gradually renamed, though some ships retained the "Nedlloyd" name prefix. This, as I say, happened several years ago.
Nedlloyd and P&O Nedlloyd no longer exist as operating companies, so there will be no new ships bearing such names. On the other hand, when Maersk purchased the liner division of Safmarine, they decided to retain the Safmarine brand, hence ships are still being built or renamed with "Safmarine" names.
