Subsea Tensioner Tools Plates

Tri-Star Industries is capable of designing and producing tensioner's fixture plates for subsea flange joints This reduces set-up and operation time especially for the subsea environment where tight schedule always persist. With the introduction of this tool plate, divers no longer need to ' lock-in ' tensioners, one at a time on each stud bolts. This time consuming task is made easier especially for large size tensioners eg 3.0" to 4.0 " bolt sizes..Simply maneuver tools plate into position and adjust the jacking screw to allow tensioners to slide into studs. It is securely mounted on skid , designed to be lowered to the sea bed . Subsequently , air lifting bags are used to lift them off the skid to be aligned onto each flange for tensioning. Concurrent 50% tightening will need only 1 set of tool plate, whereas concurrent 100% tightening will need 2 sets of tool plates, saving diving time and costs!

Submarine Bolt Tensioning System

The picture above shows our Submarine SM bolt tensioning tool applied to a typical flanged joint. The unique and revolutionary light weight Quick Reaction Nut of hinged design makes this the most diver friendly tool available today Stainless Steel construction alleviates corrosion significantly improving operational reliability in the harshest of environments.
