Kraken Subsea can produce Free Flooding Filters used to prevent the ingress of unwanted particles into a pipeline during subsea flooding operations. These systems are typically used during laydown of pipelines to help with stability however they can also be used with pipelines previously placed on the seabed.
Kraken Subsea has integrated a data logging system into Little FRANK allowing the chemical flowrate, total chemicals injected, bulk water flowrate and total volume injected to be monitored and recorded during the free-flooding operation. This allows later data analysis to be carried out ensuring the system was correctly treated.
AUTONOMOUS & VARIABLE CHEMICAL INJECTION
Kraken Subsea has developed the autonomous systems onboard Little FRANK which are capable of regulating the chemicals injected into the system. It is capable of adjusting the chemical injection rate to match the variable flowrates seen during free flooding. This ensures an even distribution of chemicals throughout the system. The autonomous systems developed benefits from our extensive knowledge and experience in the pre-commissioning field.
REDUCED CREW & SPACE REQUIREMENTS
Little FRANK key differentiator is that it requires no crew for most operations and only a single technician for ad-hoc maintenance and refilling for longer/multiply trips. This combined with a large reduction in deck space required compared to traditional flooding systems means smaller vessels can be used saving our clients significant cost.

Filters will be designed to project specific requirements (μm, flowrates, water depths etc) and minimise backpressure in the system. Typical flowrates range from 20 - 4,400 litres per minute.
The unit can be adapted to record various parameters during the free-flooding / chemical injection operation
Diver & ROV Operable
Little FRANK is designed to be simple to use and be operable by both divers and ROV. It's autonomy means that once setup, it does not require further support or monitoring.
Simple Connection Systems
A simple hotstab receptacle is utilised for connecting Little FRANK to your pipeline system. At Kraken Subsea we can also supply an appropriate connection hose into your system.
Multiple chemicals can be stored ready for autonomous subsea injection at specified delivery rates.
Little FRANK can be modified to suit various subsea baskets. Whether your project has a footprint or weight limitation, we are sure we can tailor our design to meet your needs.
