Thank you, Pieter. I appreciate the correction on my structural term. I can certainly understand the benefit of not having the web frames inside the tanks!

This ship was build by Dalian, in 1998, as yard number PC1100-1.She was the first of a long series of 110000 DWT product tankers, which includes a number of tankers for A/S Torm and the long series of MAERSK P... tankers The "breakwaters" are actually external tank stiffeners, in order to make the tank interior as flush as possible.

Thank you, P. F. And I obviously mistook her breakwaters for bulk carrier hatches. I sure do appreciate your help!

This is the former crude oil tanker "SEAQUEEN" IMO:9138599. Change of name in 2007 to "PREM DIVYA".
