Project Plan

General Description

The natural gas generator sets in this project are main power supply for the rig. There are 3 sets 1000kW/600V gas generators (1000kW is combined by 4 sets of 250kw generators) and 1 set 500kW/600V generator. All generators are synchronized. According to actual working conditions, maximum load of the rig is 3200kW (less than 20% of the whole operation time) and normal load is less than 2400kW (80% of the operation time).

Work Flow of the Natural Gas Generators

Based on actual operation conditions and client's requirement, work flow of the natural gas generators is as following:

High pressure natural gas at 6-22MPa comes from CNG tanks to pressure reduction skid through unloading system. The gas flow will be led into pressure adjusting and heat exchange system in the skid and after twice heat exchange, it will flow to flow meter and finally comes out natural gas pressure ranges from 0.4-0.9 MPa. Low pressure natural gas (higher than 0.45MPa) is transferred to generator sets through buffer vessel to ensure normal operation of generators. Once the generators are in normal operation, 4 generator sets will be synchronized by integrated synchroniser in sychroniser switch cabinet and then supply power to the rig.

Case Study: A rig in Inner Mongolia utilize our natrual gas generator sets as primary power. LNG tank trucks supply fuel.
