A note from the book keeping department :-)
With 8 E-vessels of 15,000 TEU (nominal 14,770 TEU stated by Maersk, and 15,011 TEU as shown recently by Ebba Maersk) and 2 vessels of 9,000 TEU Maersk Line's AE7 will have a slightly larger average weekly capacity (nominal) than the joint FAL5/AE8.
As far as I recall the figure for MSC SILK's weekly average is around 13,800 TEU?
