AQC Connectors

Designed for efficiency gains

Our AQC connectors have all been designed, developed and qualified by our in-house team of expert riser system engineers to reduce lead-times, capital and operational costs. This patented technology offers unrivalled efficiency gains and enhanced safety during operations.

Fast and efficient rig make-up

We’ve designed all our AQC connectors to offer fast and efficient rig make-up, with no loose parts and gas tight sealing technology.

As an OEM for oilfield equipment, we can provide our AQCs as part of a complete installation package, or as standalone items.

It’s a unique offering that gives customers significant technical advantages, as well as both opex and capex savings.

OEM designed and tested
Fatigue compliant
Range of ratings available, from 5-15k PSI
Qualified to ISO 13628-7 and/or API 16a

As a drilling riser system specialist, we also supply a variety of other connectors which can be integrated into subsea or surface riser applications, ensuring a fully optimised solution. All connectors can be made available to rent on their own with the complete suite of running and operating equipment, or as part of a complete riser supply. In addition, we can provide a trained tea

Supporting industry decarbonation goals

Our AQC riser system connector range offers operators reduced make-up and break-out time during utilisation, versus a standard flange system. This is estimated to save circa one rig day per unit, per well, using previous service report data. The saving of a day’s operational time per unit, equates to 67.71 tonnes of CO2e (using performance data from a mid-range jack-up).

Our range of Aquaterra Energy AQC designed and manufactured riser system connectors include:

AQC-SR: Subsea High-Pressure Drilling Riser Systems for HPHT operations
AQC-CW: Completion and Workover riser
AQC-BC: Surface riser connector

Minimum Facility, Maximum Agility: Delivering a lightweight CCS topside for legacy infrastructure

As carbon capture and storage projects progress towards delivery, operators are increasingly looking to maximise the value of existing offshore assets. When a major North Sea operator needed a new CCS topside to integrate with a legacy jacket, Aquaterra Energy delivered a value-engineered solution that reduced weight, simplified systems and improved operability, while maintaining full […]
