Seabed Pipeline Protection, Thailand

The special project was constructed in Thailand to protect the HDPE pipeline on seabed. It might caused some damages when installation; therefore, applying a structure to protect the pipeline was highly important.

In this case, in order not to cause any damage to pipeline by scouring or moving when installation, the project owner needed a structure to shield the pipeline; hence, the best solution was to use ACEFormerTM geotextile mattresses as the protection for pipeline.

The design engineer selected ACEFormer™ geotextile mattresses filled with sand as a shelter to protect the pipeline attacked by current directly; the anti-scour under the pipeline and the flexible structure would not injure the pipe as well.
ACEFormer™ of this project was formed of ACETex^® PET 250-I geotextiles with good abrasion resistance against tension during construction.
Hanged the ACEFormer™ geotextile mattresses panel first which was prefilled sand on the ground and delivered to the pipe protected location; then, dropped the sand-filled ACEFormer™ geotextile mattresses down carefully to cover the pipe as the shield.

The project was finished in 2008, and it is still in a very good condition with high efficiencynow.
