the day of may 7 may be called that of happy events in pairs for dsic offshore, where a5000 deep-water semi-submersible drilling platform and bt4000-1 semi-submersible drilling/repair platform built by her have undocked smoothly on the same day, marking that dsic offshore has accomplished the production milestone of two types of products in dock - “building and undocking simultaneously” at the first time, which has laid a good foundation for next-phase delivery of the platforms. |
