Vår målsättning med detta examensarbete var att ta fram en nödbogseringsmanual till skolfartyget Calmare Nyckel. Denna skulle vara helt i enlighet med de regler och riktlinjer som fanns tillgängliga och underlätta beslutsfattandet för besättningen i situationer som kräver nödbogsering. Projektbeställare var Bengt Karlsson, befälhavare på Calmare Nyckel, och efter ett inledande möte sattes arbetet i gång då i form av ett projektarbete inom ramen för examensarbete. Vi har baserat manualen på i första hand aktuell lagstiftning och riktlinjer men också på andra fartygs nödbogseringsmanualer vi bedömde som bra.Arbetet förflöt enligt utsatt tidsplan och det slutgiltiga resultatet blev väl utfört enligt oss och projektbeställaren.Calmare Nyckel är nu utrustad med en fullt fungerande nödbogseringsmanual som vi med säkerhet kan säga uppfyller alla tillämpliga krav som ställs på en sådan. Vår förhoppning är att manualen aldrig kommer att behöva användas i skarpt läge, men däremot regelbundet fungera som underlag i övnings- och utbildningssyfte. / Our goal has been to develop an Emergency Towing Manual for the scholar ship M/S Calmare Nyckel. It would be in line with present rules and conventions and facilitate decision-making in situations requiring emergency towing. Our project client is Bengt Carlsson, Master on the Calmare Nyckel, and after intitial talks the work was set in motion taking form of a project.The Emergency Towing Manual is foremost based upon present legislation and guidelines but also on other ships ETM:s, which we have found succesfull.The project was carried out within our schedule and the resulting manual was well appreciated by us and the project client.M/S Calmare Nyckel is now equipped with a fully functioning Emergency Towing Manual which meets all applicable demands. Our hope is that the manual will never have to be used during real emergencies – however, regularly refered to in exercises as part of the onboard emergency prepardness.

The dynamic behaviour of an active-passive motion compensation system for handling towed marine vehicles is examined, and a mathematical model developed. In the analysis, the passive system considered is pneumatic, while the active system is electro-hydraulic. The towed body is assumed to be a point mass subjected to hydrodynamic drag, and attached to the motion compensator by means of a linear spring representing the cable. It is not intended, in this project, to model the towed body in greater detail. The equations of the passive, active, and towed body systems are derived, and linearized to permit a relatively simple frequency-domain solution. A time simulation based on the nonlinear equations, including Coulomb friction in the compensator, is developed for use on an IBM Systeis/370 computer. A laboratory model is used to conduct experiments at three frequencies, and the results indicate good agreement between the linear, simulation, and real models. Extension of the equations to cover multi-frequency inputs, two-dircensiona1 towing cables, and slow-acting servovalves is also discussed to facilitate application to marine systems. / Applied Science, Faculty of / Mechanical Engineering, Department of / Graduate
