The Shipboard Office' : The Role Of It And Multi-Media Systems In Managing Engineering Operations And Maintenance Onboard Ship, Okechukwu Ebere Sylvanus Obara

World Maritime University Dissertations

This dissertation is an investigation of the roles of information technology and multimedia systems in the management of engineering operations and maintenance onboard ships. It considers the implications and constraints of adopting these technology tools on the economies of ship owners or managements companies, Maritime Administrations, and the Maritime Education and Training Institutions, especially in the developing countries. The study reviews the various shipboard maintenance policies and management techniques currently being practised in the traditional shipboard office with a view of understanding its constraints and the needs of adopting the various technological tools and systems. It also examines critically, the …

Enhancing Commercial Aircraft Survivability Via Active Venting, Roger L. Veldman

Dissertations

A new technique for enhancing aircraft safety in the event of an on-board explosion was studied. The method under study employs deployable vent panels located on the fuselage which are activated by an array of pressure sensors in the aircraft interior. In the event that an explosion is detected, appropriate vent panels are rapidly released from the aircraft. This approach seeks to provide timely relief of explosive pressures within an aircraft to prevent catastrophic structural failure.

In this study, the approximate time scale of an explosive detonation and the subsequent sensing and electronic processing was determined. Then, the actuation response …
