The configurable Pull Head system has been developed using the Blue Logic ValveStab design as basis. This solution results in an extremely compact and rugged Pull Head where the Pull Head, fluid connector, flange and lifting lug are machined out of one solid steel body. The interface flange can be welded or bolted to the Pull Head, thus the very same Pull Head design can be utilized for different interfaces.
The excellent flow performance benefitted from the ValveStab principle provides several unique features, and for most projects significantly reduced vessel time. The compactness of the Pull Head allows for pull - in through most Guide Tubes without need for changing from an intervention head to a dedicated Pull Head thus saving valuable vessel time. Blue Logic Pull Heads have been successfully operated on projects like Gina Krogh, Knarr and Mariner.
The ValveStab connector principle is a clean connection system ensuring minimum fluid spill or water ingress into the operating fluid during operation. We believe this is the cleanest and most environmentally friendly subsea connector system available.
