DSME gets approvals for VLCC design

Sep 06 2019

Daewoo Shipbuilding & Marine Engineering (DSME) has received approvals for a VLCC crosstie-less design.

The shipbuilder applied for the patents from eight countries for a new type of cargo tank structure without crossties (horizontal stiffeners), which have been fitted to VLCCs since 2010.

Starting with patent registration in Japan in 2015, it was approved in the US, Greece, UK, Norway, France and China in 2016.

DSME said that the final approval needed was received from the South Korean Intellectual Property Office in July, 2019.

The shipbuilder has been developing the crosstie-less concept since 2009, and has applied this design concept to VLCCs since 2011.

This concept is aimed at securing the required strength for design loads, including sloshing, by enhancing the existing vertical structural members.

DSME said it had delivered 47 of the total of 71 VLCCs without crossties thus far, with another 24 currently being built.
