Hydratight’s Aquajack® subsea tensioners allow divers to perform the tensioning process with tools designed specifically for their unique requirements.

Tensioners feature a compact design and long piston stroke. The unique Split Nut® design of these tools allows rapid application to long bolts and damaged threads, and rapid tool removal. By tightening all the bolts on a joint simultaneously a saving of up to 80% can be achieved over alternative methods.

Hydratight’s Aquajack® subsea tensioner achieves this to provide the most cost effective solution to subsea bolt or stud tightening.
