Cable weight reduction onboard ships

Request Number N184976
Need details

We are seeking novel approaches to replace traditional data transmission cables on board our ships with wireless transmission of signals from sensors for non-critical systems.




The companies comprising the Swedish-based Stena Sphere represent one of the largest private shipping groups in the world. We are seeking solutions that can be applied to cargo and passenger ships that travel in all of the world’s oceans.


Historically, our ships use heavy cables to transmit data for non-critical systems like Heating, Ventilation, and Air Conditioning.  These cables add 2-5% to the dead weight of ships, increasing fuel consumption.  We would like to reduce this by 50% by eliminating the need for cables for non-critical systems 


Key Success Criteria

Evaluation Criteria:

  1. Technical Viability-- Solutions proposed must be based on sound scientific principles and have laboratory or pilot scale data that demonstrate efficacy.
  2. Scale up Potential—Solutions proposed must have a clear pathway to be application on commercial ships within 1-2 years. The ideal partner would be able to lead the design and installation of full-scale systems. Solutions already practiced in marine markets have higher value.
  3. Costs—Total system cost (components and installation) must be comparable to conventional cabling.  
  4. Ownership—Solutions covered by patents have higher value. At a minimum, proposed solutions must not be prohibited by other patents in the field. 


We are seeking an experienced system provider for monitoring and automation to run a pilot project for non-critical systems, with the capability of rolling out to new ships currently under design. 



Possible Approaches

We would like to reapply proven technologies like wireless transmission of signals via a smart grid.  However, suggested approaches must be suitable for use in the marine environment.  Key concerns include:

  • Signals must be able to transmit through steel bulkheads
  • Equipment must be able to withstand vibration and variations in temperature and humidity
  • Signals must be protected to prevent breaches in security


Approaches not of interest
Preferred Collaboration types
  • To Be Negotiated
Items to be submitted

We are looking for concise, non-confidential proposals. The proposal should describe the technical approach and should ideally include information on the technological readiness of the proposal, any proof of concept data, reference to any peer reviewed publications, and potential route to commercialization.

Good morning. I have a question regarding this request. The requirements indicate the need for wireless signals to travel through steel bulkheads. While wireless signals can travel in conducting vessels, that propagation will not take place *through* steel. The transmission will occur through apertures in the structure (doors, airvents, etc.) unless the entire hull is completely and totally sealed. Please clarify/advise. Thanks.
