Working with alarms on ships ICT work on ships
Alarm indicators are a very simple and important user interface for many control tasks, and are known to be problematic. Alarms on ships have increased in number and importance. Recent incidents such as Savannah Express, Aquitaine and others have identified a number of important issues in the way that alarm systems support safe and effective work. The state of alarm systems onboard is inconsist...
متن کاملShips, ports and particulate air pollution - an analysis of recent studies
The duration of use is usually significantly longer for marine vessels than for roadside vehicles. Therefore, these vessels are often powered by relatively old engines which may propagate air pollution. Also, the quality of fuel used for marine vessels is usually not comparable to the quality of fuels used in the automotive sector and therefore, port areas may exhibit a high degree of air pollu...
متن کاملAdaptive wave cancelation by acceleration feedback for ramp-connected air cushion-actuated surface effect ships
We solve the problem of cargo transfer in high sea states over a ramp from a large, medium-speed, rollon/roll-off (LMSR) vessel to a smaller connector vessel of a surface effect ship (SES) type. Our aim is to reduce rampmotion between the LMSR and SES in order to provide a safer environment for cargo transfer. We design an air cushion actuated controller to estimate and cancel the wave disturba...
متن کامل00S-SIW-126 NATO HLA Federation for Study of Air Vehicle Landings on Ships
In November 1997, the NATO Naval Armaments Group on Ship Design (NG/6) established a Specialist Team on Simulation Based Design and Virtual Prototyping (ST-SBDVP). The purpose of the Team is to share information on the benefits, risks, and costs of instituting the technologies and processes of SBDVP applied to the acquisition of naval warships. A specific challenge undertaken by the Team is an ...
