we install submarine cable from mainland to island ,island to island, and across river, lake, big reservoir, etc. As well as, we install submarine cable from seashore to oil platform or between oil platforms with skilled technique. We install cables while laying and burying in the same time. The cable burial depth can be 2/3/4/6 m under seabed surface.

Scope of business
- cable laying and burying
- cable repairing
- Offshore windy farm power cable installation
- Offshore detection cable installation
Now, more and more submarine cable get breakdown for anchor ,drag of fishing net, etc. We specially develop the vessel and machine to repair submarine cable. We also supply technique services to test cable fault and find breakdown point, and also we can survey cable route to find the cable installed years ago. when we repair cable, we manufacture joint box for power cable or optical fiber cable. The joint box can be cast-iron or stainless steel.
We completed the subsea cable installation in the first offshore wind farm of Asia in 2010 -“Shanghai Donghai Bridge 200Mw offshore wind farm model project”.
Now we built up large scale installation vessel and large diameter carrousel for 110-220 kV power cable with long length, which are under construction in China.

We also cooperated with famous research institutes in China to study the offshore/deep sea observation submarine cable projects, including Chinese Acoustics Research Institute，No. 715 Research Institute, No. 23 Research Institute, Tongji University and so on.
Now we have developed ROV and DP1 vessel system to complete those deep sea observation cable projects.
