SUB-HANG™ Topside Hang-Off Clamps

Product Overview

SUB-HANG™ Topside Hang-Off Clamps provide a structural support between the riser or umbilical and the outer J-tube. Systems can also be supplied with a seal module that provides full sealing capability in the annulus between the riser and the J-tube. The SUB-HANG™ Topside Hang-Off Clamps is fitted with a continuous housing that is preinstalled prior to riser pull-in. Once the pull-in is complete Subsea Energy Solutions service engineers perform the final assembly of the unit. It is essential to perform a seal verification test prior to leaving the worksite. 

Designs are subjected to third party verification and a factory acceptance test that verifies both load holding and sealing capability in a test rig that simulates all offshore conditions.
