SURVEY PORT OF HOUSTON CRANES TRANSPORT

Project Summary

Three new ZPMC container cranes were transported from Shanghai to the Port of Houston in summer of 2017. Argonautics Marine

Engineering, Inc. provided the review of all engineering calculations and the marine warranty survey for the transport. In mid July, the

1,450 t heavy cranes were each rolled onto the ZHEN HUA 13 at the Changxing base of Shanghai Zhenhua Heavy Industries Co.,

Ltd. and secured to the vessel deck using steel pipes and cables. The seafastening of the cranes to the vessel deck and the internal

lashings were surveyed after loading, to ensure these were executed in accordance with the previously reviewed ZPMC project

drawings.

After loading of the second crane destined for Dakar, Senegal, the vessel departed Shanghai, sailed via Cape of Good Hope to

Senegal for delivery of the first two cranes, after which it continued to succesfully deliver the three Houston cranes to the Port

of Houston.

The project scope included:

specialists in marine heavy-lift transportation engineering
