Recently, the world's most advanced A5000 deep-water semi-submersible drilling platform built by the Marine engineering company of large ship group has successfully completed the sea dp-3 closed-loop dynamic control test. The trial lasted only a week is complete DP - 3 level closed loop power control system related all complex tests, and the key of the whole ship short circuit test one-time success, creating the world's first semi-submersible platform DP - 3 closed loop short circuit test a successful precedent, marked the ship group in the new and high technology intensive ocean engineering field of deepwater semi-submersible platform walk in the forefront of the industry.

Semi-submersible platform dp-3 closed-loop dynamic control system is the most advanced power system control technology in Marine engineering field. Generator in closed loop mode according to the measured average operation time can reduce about 39%, greatly reduce generator maintenance time and costs, reduce drilling rig oil consumption by 18%, save costs at the same time can effectively reduce emissions, nitrogen oxides can reduce about 39%, decrease sulfur emissions by about 20%, decrease carbon dioxide by about 22%.

A5000 type of management system USES a semi-submersible drilling platforms Kang Shibo company DP - 3 level closed loop advanced generator intelligent management solutions, is the world's first closed-loop mode can control run two generator online project, it is also the first domestic use the same panel on the two generator configuration control station project independently. In advanced generators in the commissioning process of the management functions, the project first introduced a test matrix table, make the function of AGS and all kinds of load in power closed-loop mode according to different failure or hidden failure to implement the grid generator protection timeliness to verify.
