Startup Pile Lingshui (2020) & Liuhua 21-2 (2021)


Lingshui17-2 gas field is located in the northern part of the Qiongdongnan Basin in the western continental shelf of the northern South China Sea, with water depth of 1220m to 1560m. LS17-2 gas field is approximately 149km away from Sanya, Hainan Province, about 160km southeast from existing Yacheng 13-1 gas field, and about 90 km from gas export pipeline (YC13-1 to Hong Kong). The distance between LS17-2 gas field and the nearest onshore terminal (Nanshan terminal of YC13-1 gas field) is approximately 156km.

The development of LS17-2 gas field consists of subsea production system, one SEMI and subsea pipelines. The subsea production system comprises one west manifold and three east manifolds. LS17-2 SEMI is a SEMI platform and located near Manifold EAST1. Well fluid from west production loop will be transported to LS17-2 SEMI for process through two 10” pipelines and two 10” SCR risers. Well fluid from all east manifolds will converge at Manifold EAST1 and then be transported to LS17-2 SEMI for process through two 12” SCR risers. After processing, qualified natural gas shall be pressurized and transported to subsea pipelines from YC13-1 platform to Hong Kong through an 18” subsea export pipeline. Condensate oil shall be sent to the storage tank on LS17-2 SEMI and be exported by DP Shuttle oil tanker.

Besides the geotechnical and structural analyses and modification of the suction pile for this project, SPT Offshore was (within the contract of Allseas) also responsible for the provision of suction services for the installation and removal of one suction anchor pile offshore at 6 different locations.
