    • DESIGN&ENGINEERING INTRODUCTION“No product is an island. A product ismore than the product. It is a cohesive,integrated set of experiences. Thinkthrough all of the stages of a product orservice – from initial intentions throughfinal reflections, from first usage to help,service, and maintenance. Make them allwork together seamlessly. That’s systemsthinking.”Don NormanThis booklet is a summary development is to create on absorbent of the sameof a spring project for understanding and name, that can be used both Synergy between different fields is best achieved in group work environment, therefore nine designstudies of product design common work culture for on water and on land.

    • DESIGN&ENGINEERING MAPPING OF THE THEMEABSORBENT AND OIL POLLUTION All these services were visited as well to get an adequate information on what must beAbsorbent is a bibulous material, which is concluded while developing a skimmer.used to remove a variety of liquid pollutants- chemicals, oil, water, mazsut and otherdangerous liquids. Absorbent that is meantfor oil pollution removal has the an ability to MEETINGS WITH PARTIESremove the stickiness of oil, which makes thecleaning easier and quicker. 1. BONUSVIAWhile speaking about oil pollution, it is Before we started to create a skimmer, therenecessary to know that different oils have was a meeting with Bonusvia representativesdifferent viscosity, which means that lower and „design and engineering“ workgroup,the viscosity, the thinner and less sticky it where company’s wishes and specificationsis and harder to clean by using methods of were discussed. By the end of the firstadhesiveness. Therefore absorbent helps to meeting the following specifications andclean oils with low viscosity, even from water, criteria became apparent:from where it is not possible to clean it with theprinciple, where oil should stick to the brushand be removed from water. • Skimmer works with absorbentIf there is an oil pollution, then the first to be • Skimmer works on watercalled is a Estonian Rescue Service, whoseresponsibility is to take care of the pollution on • Suitable for small bodies of water -water, and the next is Estonian Fund of Nature, lakes, rivers and for harbours andwhose responsibility is to take care of the shores.nature and animals on ashore.

    • DESIGN&ENGINEERING BACKGROUND HAND TOOLSAs study group was encouraged in first offering an absorbent based skimmer for low From a meeting with the ELF volunteers from the boat with manual tools was theirstage of contextual analysis look the waters that were effective in cleaning viscous responsible of shoreline and bird cleaning, the regular practice. Question that was raised:field of oil cleaning in wide perspective. oil, currently an less developed area in oil study group learned about the difficulties of How to ease the manual shorelineFrom contextual understanding also from the cleaning. As skimmer was a meant to be shoreline cleaning, which is a time consuming cleaning using absorbent?market analysis settled out that there is an sold with the base product absorbent, manual labour. Study group visited Muugaopportunity to widen the market of Bonusvia study group asked what other Port and studied their oil cleaning practices.absorbent company.
