Kraken Subseas engineering team has designed and built Little FRANK to improve efficiency and reduce the cost of flooding subsea systems while ensuring our clients piece of mind. Little FRANK uses hydrostatic seawater head to flood subsea systems, without the need for a connection to a topsides vessel or installation.
The system was also designed to be more compact and lighter than its competition, reducing the deck space and lifting requirements associated with a conventional free flooding operation. This compact ROV friendly design allows for the system to be manoeuvre easily for deployment and recovery to & from 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 FREE-FLOODING SYSTEM
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.
