Trenchless Taiwan Engineering Services Co Ltd (TTESCL)

Trenchless Taiwan Engineering Services Co Ltd (TTESCL), was awarded by the EPCI Contractor Jan De Nul for the provision of HDD services for 4nos. HDPE ducts of 500mmOD at a total length of 2.154 kms for the Formosa 2 Offshore Wind Farm in Miaoli County Taiwan. TTESCL provided its expertise for the HDD drilling operations while Jan De Nul was responsible for the marine operations and overall coordination of the works. After approval of the detailed design and engineering by Formosa 2 Wind Power Co., Ltd, the 150T HDD rig was placed at the Transition Joint Bay (TJB) and the pipe pulling was done from the offshore side. The HDPE duct pipes were supplied by Jan De Nul and TTESCL welded the pipes including visual inspection by in-duct camera. The works were successfully completed after performing all pigging & gauging operations and sealing the duct ends at the TJB.

TTESCL personnel delivered round the clock performance in order to timely complete the works. Formosa 2 Project Director Kimberly Cram said “Trenchless have now completed their work on the HDDs required for the export cables for Formosa 2. This included implementing a variety of mitigation measures to manage the risks, which resulted in successful completion of the works.”
