FirstFiber Articulated Pipe
2018-07-06FirstFiber Articulated Pipe has been developed to provide shallow water abrasion and impact protection for submarine cables.
FirstFiber is unique in that it clips together, avoiding the nuts and bolts of traditional articulated pipe. This clip together feature allows quick real time application during laying and a much simplified diver installation onto pre-laid cables.
The FirstFiber system comprises two different cast segments which are identified as uppers and lowers. Each successive pair of segments clips over and retains the end of the preceding pair.
A wide range of adaptors and attachments are available for use with FirstFiber Articulated Pipe. These adaptors and attachments allow the reversal of application direction and interfacing with other cable protection measures such as directionally drilled pipes, pipe flanges and concrete abutments.
