PowerCube
The PowerCube is a novel battery driven hydraulic power unit which can augment or replace traditional accumulator based solutions with the following key benefits:
-
Energy density of the battery system is c.2,000x that of accumulators resulting in significant space and weight savings
-
State of the art battery cells maximise safety providing full thermal and chemical stability
-
Variable displacement pumps with full and precise hydraulic control
-
Capable of operating at up to 5,800 PSI
-
System can be stacked or distributed to meet space requirements offering flexibility of configuration
-
Multiple cubes can be combined providing scalability of redundancy and power
PowerBank
The PowerBank is a novel closed loop hydraulic chemical injection system that enables:
-
Hydraulic functions to be powered close to or on the X-tree; and
-
Flow assurance chemicals to be stored and injected locally at the X-tree
By providing power close to the X-Tree, the PowerBank allows for a reduction in the number of hydraulic lines required in the umbilical, therefore drastically reducing umbilical cost
The system comprises:
-
Subsea fluid storage unit
-
Pumping module for chemicals and hydraulic fluid (up to 8 independent pump units)
-
ROV handling allows for ease of maintenance
Subsea Battery Systems
QL Tech has developed a modular scalable subsea battery system which can be tailored for a variety of applications - both with in drilling and production.
Using state of the art lithium ion technology, our systems are able to pack high power into a low footprint and weight.
The battery assemblies feature an in-house high reliability battery management system so are suitable for mission critical applications.
Assemblies can be provided with or without QL Tech's in-house designed inverter / motor controller which is rated for up to 200kW.
A smaller 15-20kW inverter is currently in development.
