Capacity enhancement for deep water operations
ENGINEERING SOLUTIONS AND CAPABILITIES
THE CHALLENGE
Operations are taking place in much deeper waters and in more diverse locations,
and when umbilicals or cables are deployed in deeper water, the holdback tensions
generated are much greater than in more shallow sites.
Technip Norge AS contacted us to see if we had a tensioner for hire with 85Te outboard
tension capabilities. Our response was to explore an innovative approach and so
Aquatic’s in-house specialist engineering team quickly identified that it would be
possible to design a solution that combined two 50 tonne tensioners.
THE SOLUTION
Aquatic built a 50te tensioner (AQTT-10E-50 DUAL) that can be used individually or
paired with another 50te tensioner to achieve almost double the capacity of a single
tensioner. The dual tensioner system has a special manifold which was developed to
allow two machines to work in tandem. It operates from a single power pack which
provides hydraulic power into the tensioners equally through this manifold, taking
multiple inlets or outlets into one. The manifold diverts the hydraulic fluid into two equal
streams so that both tensioners operate at the same flow rate and pressure., ensuring
a fully balanced operation.

THE OUTCOME
Working closely with Technip to fully understand their needs, Aquatic was able to
develop an innovative piece of equipment in response to a commercial need. The
client was involved with the testing, both at Aquatic’s operational facility in Peterhead
and on its own vessel in France.
As with all Aquatic’s equipment fleet, the modular nature of the AQTT-10E-50 DUAL’s
design enables it to be broken down very simply into component pieces and packed
inside a standard container for transportation by road and/or sea.
