Why our h4 connectors?

At Aquaterra Energy, we offer a choice of connector variants to maximise operations across a variety of applications and environments. These include the market-leading, field proven, deep water and heavy duty H4 Subsea Connector for use on its own, or as part of our High Pressure Riser System.

  • Field proven
  • Readily available
  • Easy to install and remove


Providing the connection between the riser’s stress joint and the subsea wellhead or tree, the H4 Connector’s exceptionally high bending capacity means it is suited to most offshore operations. 

All our subsea connectors can be fitted with a standard ROV hot stab panel for secondary control in the failure of the surface control unit. Aquaterra Energy’s hydraulic power units (HPU’s) allow the control and functioning of all our subsea connectors.

In addition to H4 Subsea Connectors, we can supply BOP quick connects, such as our Aquaterra Quick Connect (AQC), that have been engineered to minimise rig time for riser applications providing connection between the rig BOP and the riser’s tension joint.

By using our Aquaterra Express service for the provision of your offshore tools, you will not only reduce the CAPEX on your project, but still ensure a great quality tool is delivered for the job it was intended for, and when it is needed by. Backed by our in-depth experience of working with operators and contractors around the world, Aquaterra Express gives customers access to products with quality and integrity, as well as access to the best and most innovative thinking in the offshore market.
