Fouling on ships is the accumulation of unwanted plants or animals on submerged areas of the hull. This fouling may impact operation of the ship as well as provide a route for transport of invasive species. Fouling is particularly bad in areas of low flow such as sea chests and bow thruster spaces and these spaces are not easily accessed for cleaning. The Defence Technology Agency (DTA) of New Zealand, the Seeker for this Challenge, is interested in finding innovative new approaches to prevent fouling on ships with a particular interest in approaches that are effective in low flow areas.
This is an Ideation Challenge with a guaranteed award for at least one submitted solution.
Almost any surface submerged under water is subject to fouling, which is the growth of microorganisms, plants, algae, and small marine animals. Fouling on ship hulls impacts drag through water, can clog intakes, and is a primary route for the transport of invasive species from one ecosystem to another. Sea chests (recesses in ship hulls from which water is drawn for cooling, ballast etc.), bow thruster spaces, and other areas of low water flow are subject to particularly bad fouling and are typically not easy to inspect or access for cleaning. Antifouling paints that contain toxic elements have been used but have limited effectiveness in these areas and require periodic reapplication. Currently this fouling is addressed through periodic manual cleaning while the ship is in dry dock approximately every 2.5 years. The Seeker is searching for novel approaches and concepts to prevent fouling in low or no flow, hard to access areas of ship hulls.
This is an Ideation Challenge, which has the following unique features:
Submissions to this Challenge must be received by 11:59 PM (US Eastern Time) on 29-Nov-2021.
Late submissions will not be considered.
After the Challenge deadline, the Seeker will complete the review process and make a decision with regards to the Winning Solution(s). All Solvers that submit a proposal will be notified on the status of their submissions; however, no detailed evaluation of individual submissions will be provided.
Members of the New Zealand Defence Force (NZDF) and their families are not eligible to receive awards for this Challenge.

What is InnoCentive?
InnoCentive is the global innovation marketplace where creative minds solve some of the world's most important problems for cash awards up to $1 million. Commercial, governmental and humanitarian organizations engage with InnoCentive to solve problems that can impact humankind in areas ranging from the environment to medical advancements.
What is an InnoCentive Ideation™ Challenge?
An InnoCentive Ideation™ Challenge is a broad question formulated to obtain access to new ideas, similar to a global brainstorm for producing a breakthrough idea or market survey which may include ideas for a new product line, a new commercial application for a current product, or even a viral marketing idea to recruit new customers. Ideation™ Challenge submissions are typically about two written pages, and Seekers receive a non-exclusive, perpetual license to use all submissions.
In an Ideation™ Challenge, Solvers may:
Solvers should not reveal any confidential information in their submissions. Often the Ideation™ Challenge will be followed by one or more of the other three Challenge types to further develop the ideas and gain Intellectual Property protection when the concept has been well-defined.
