Polymarine Ltd have manufactured and supplied inflatable products for the marine safety and survival applications for over 20 years. The company now employs 9 people and has sales of 1.1 MEURO. The company's product range includes complete inflatable craft as well as specialised components for these systems. The company's products are based on the use of a variety of mechanical manufacturing processes, and the company had no experience in the area of microelectronics.

The company markets mechanically activated inflation system for inflating marine safety and survival products such as Liferafts, Lifejackets, Inflatable Marine Escape Systems and Emergency Buoyancy Systems. The inflation systems for these products traditionally have used compressed gas for inflation. The gas is released in an emergency by a mechanical actuator and valve system. The weight and size of these gas cylinders is a major disadvantage when used in weight sensitive applications such as commercial and military aircraft.

Polymarine have developed a new patented, inflation system which uses a chemical gas generator to advantageously replace the traditional compressed gas supply systems. The objectives of the Application Experiment was to produce a low cost and low weight inflation system for survival applications. The microcontroller incorporates in the improved product performed the following functions:

  • to actuate these gas generators in response to several sensor inputs.
  • to operate several gas generators in a predetermined sequence to maximise the buoyancy of the inflatable.

The development of the microcontroller-based gas generator will result in an unique and class-leading patent protected product. The use of the gas-generator will have a significant impact on the survivability, and offer a lower cost and weight solution. These advantages will lead to increasing sales and profits for the company.

The cost of the development work supported under FUSE funding was 34 KEUR. The development of the prototype required 8 months to complete. The payback period for these prototype development costs is 27 months.

The return on investment on the costs of prototype development is estimated at over 1,290 % over the product's 10-year patent protected lifetime.
