Subsea and Topside Tensioning

Tensioning permits the simultaneous tightening of multiple bolts. Tensioners are connected in sequence via a high pressure hose assembly to a single pump unit. This method ensures that each tensioner develops the exact same load and provides a uniform clamping force across the joint, avoiding damage and ensuring a secure sealed connection is achieved.

Tensioning is the direct axial stretching of the bolt to achieve preload which ensures that inaccuracies created through friction are eliminated. Simple hydraulic pressure replaces the mechanical effort to create torque however tensioning does require longer bolt lengths and a suitable seating area around the nut.
