MARPOL Annex 6 Explained: Prevention Of Air Pollution From Ships

by Engr Matahula, Smart Pwashemeno MARPOL Annex 6, an integral part of the International Convention for the Prevention of Pollution from Ships (MARPOL), sets forth regulations and standards for controlling air pollution from ships. With the growing concern over environmental sustainability, Annex 6 aims to reduce harmful emissions, particularly sulfur oxides (SOx), nitrogen oxides (NOx), and particulate matter (PM), in order to protect the marine environment and human health. This article provides an overview of MARPOL Annex 6, delving into its historical context, its implications for the shipping industry, and the challenges and potential solutions for its implementation. It also examines the impact of Annex 6 on emission control areas (ECAs), compliance measures, and future develo...

How to calculate Specific fuel Consumption On Merchant Ships With Mathematical Examples

By Engr Matahula, Smart Pwashemeno on Specific fuel Consumption On Merchant Ships To calculate specific fuel consumption (SFC) on merchant ships, you need to follow these steps: Determine the total fuel consumption: Measure the total amount of fuel consumed by the ship during a specific period. This can be done by monitoring the fuel flow rate or by measuring the quantity of fuel bunkered and the remaining fuel on board. Measure the propulsion power output: Determine the power output of the ship's propulsion system. This can be obtained from the engine's performance curve or by measuring the shaft power using a dynamometer. Convert units: Ensure that the units of fuel consumption and power output are compatible. If necessary, convert fuel consumption to a common unit, such...

How Many Revolutions Do Different Aircraft Engine Types Complete Per Minute?

First of all: There is not one single speed on many aircraft engines. Big propeller engines have a reduction gearbox so the propeller runs at a lower speed than the core engine, and multi-spool turbines have an inner, high-pressure section with higher rotational speeds than the outer, low-pressure parts of both the compressor and the turbine. Take the Progress D-27 turboprop for example: It has three spools and a reduction gear, so its components run at four different speeds. Generally: The bigger the diameter, the lower the typical speed. Fan and propeller blades should run at a high dynamic pressure, but still at subsonic speeds to avoid the higher losses involved with supersonic flow. Since the tip will be the part with the highest speed, and propellers have bigger diameters than fan...

Brake failure: How to stop the car when brakes fail using these simple tips

You could have the best car on the block with incredible specs and features, but if it's got trouble with its brakes, all your commutes and trips will have to wait until they've been fixed. While brake failure is not a phenomenon very commonly heard of anymore with the advancement in braking technology, also assisted by ABS (anti-lock braking system) and EBD (electronic brake distribution) in a lot of cars today.But it is worth considering and being prepared for if a brake failure happens. So, here we take a look at what to do in case the brakes fail:- Hazard lamps are available in all modern cars and these are meant for such emergency situations. These lamps, in fact, are not meant to be switched on in case of driving in fog or in the rain, as a lot of people misunders...

New devices for conveying olfactory stimuli in virtual reality

by Bob Yirka , Tech Xplore Wearable odor generators enable olfactory feedback in VR. Credit: Xinge Yu A team of biomedical and mechanical engineers at City University of Hong Kong, working with a pair of colleagues from Beihang University and one from Shandong University, has developed two versions of a system designed to convey olfactory stimuli in virtual reality. Their results are published in Nature Communications. As VR systems become ever more realistic, designers and users have noticed that two of the senses are still very much absent in the virtual world: smell and taste. Much work has been done with the former and a little with the latter, but attempts at both still leave much to be desired. Most systems designed to add olfaction to VR have involved use of ae...
