Hitachi Zosen puts spherical LNG tanks on new gear support

Hitachi Zosen has a way of making research and development pay off. Our lengthy experience building LPG carriers proves it. Among these, the 100,000m3-tank-capacity

Esso Fuji is the world's largest.

Now our new gear support for Hitachi Zosen-Chicago Bridge & Iron gear-support type LNG carriers helps to prove it again.

We did it our way

The spherical LNG tank is designed with external horizontal ring girders in the equatorial section.

Support blocks on the bottom of the girders have a gear configuration, and each is accommodated in a recessed construction on the supporting deck with load bearing insulation blocks in between.

The contact surface of the insulation blocks is smoothly machine finished to support the weight of the tank and cargo horizontally and allow free radial contraction toward the center of the tank during cooling. While restricting vertically and radially longitudinal and traverse loads from ship motions.

There's no integral structural connection between the tank and the ship's hull, so there's free displacement for thermal contraction or retraction of the tank, no excessive stress in the tank shell and minimum bending moment at the tank equatorial section.

What it all means is the Hitachi Zosen-Chicago Bridge & Iron gear support is simple. Highly efficient. And easy to install.

This is what you want when you build an LNG carrier now or in the future. This is what you get when you come to
