SUB CONNECTED AND OUR PARTNERS
The experienced team in SubConnected have skills in marine high voltage electrical systems, sea cables, marine connections, monitoring system and green energy. We have senior international experience from wave power, cables, engineering and digitalization.
SubConnected have long term relationship with its partners and have selected them carefully. We can together provide the edge in know-how, development resources, technology and production capability to deliver solutions to our customers.
OFFSHORE
SubConnected offer bespoke systems for floating- solar and wind, a wave power parks.
The design is using a new generation of lightweight sea cables with a built in super dynamic flexibility and strength and a unique patented spar hub for connecting multiple cables with dry connection points and preventing the cables from scuffing. The system has been tested for 7 years in extreme conditions off Runde in Norway. The cables have undergone extreme longevity testing at RISE (Research Institute of Sweden) and Chalmers University of Technology have done numerous simulations on longevity and performance.
SubConnected offers an innovative, proven and extremely cost-efficient cables and spar hub systems, fully installed with long life and low maintenance. Marine Operations are faster and less expensive.
IN SHORE
SubConnected have developed an innovative patented solution with a floating submerged transformer with an Seaflex mooring solution.
For inshore solar parks on lakes and dams it’s important to ensure that the energy losses in the complete system are minimal. For this reason, the transformation to AC and higher voltage must take place close to the energy generation.
The SubConnected spar buoy is placed close to the energy generation and the transformer is submerged into the water which results in stable and optimal cooling, significantly reducing energy losses. The hub solution is easy to transport and deploy with substantially reduced wind and wave resistance. Due to this reduction the mooring system can be designed without the need to handle the larger loads.
OUR STORY
Sub Connected was formed by a team originating from Waves4Power, a swedish company developing a system that produce energy from ocean waves. A key challenge for ocean energy solutions is to find a way to transport electricity from ship to shore that survives and are reliable. The founders of SubConnected have experience from 10 years of wave power development.
To rule the waves
Marine devices in open sea are a challenge. Wind and waves will do it’s best to destroy any man-made device. Waves as high as 15-20 m are not unusual. It’s not only the device itself, but also the mooring, and in the case of wind power and the cable system that must survive and remain functional in the worst possible weather situation. Even huge construction such as tankers are vulnerable and can be destroyed in a bad storm. The experience from mooring wind and wave power devices under those circumstances limited. The experience to electrify devices like this environment is unheard off.
In the land of the blind, a man with one eye is king
Waves4Power is a wave power company that deployed a full-size wave power system outside the Norwegian west coast 2017. In parallell with the development of the wave power device, the job started to develop a system that could carry the electricity from the wave power device to shore. The type of cables needed with flexibility and strength to survive in the worst possible environment did not exist.
A completely new generation of sea cables with a built in super dynamic flexibility and strength given by Kevlar ropes integrated in the cables was developed and patented by our cable partner NKT Cables. A cable by itself was not enough, we also needed a hub for connecting multiple cables and ensure dry connection points as well as protect the cables from scuffing towards the bottom.
The system has been tested during six years in the worst possible conditions outside Runde Environmental Center in Norway. The cables have also undergone extreme longevity testing at RISE (research Institute of Sweden) and Chalmers University of Technology had done numerous simulations to simulate longevity and performance. Altogether this is the best tested cable by NKT Cables ever.
With this type off cable and the hub concept SubConnected can offer customers an innovative, well proven, and cost-efficient cable system with long life and low maintenance. A system that can be an alternative to traditional steek armored cables.To keep the cables flexible, we operate with lower voltage to keep conductors and insulation as slim as possible. This makes marine operation considerably less expensive. SubConnected prefers to utilize the hubs as connection point before going to shore, alternatively have a central platform to collect cables from multiple wind/wave power devices before going to shore.
