Articulated Pull-in Heads

The Articulated Pull-in Head is fitted to the front of a subsea umbilical to allow it to be safely pulled into position during offshore installation. It provides a secure connection point for the pull-in wire, distributes loads into the umbilical’s strength members, and allows articulation that allows angular movement so pulling forces remain aligned and do not damage the cable. Its profile and reinforced design helps guide and protect the umbilical as it passes through structures such as J-tubes or I-tubes, reducing stress, preventing kinks, and ensuring a controlled installation.
