    Z-Drive – A Z-drive is a type of marine propulsion unit and is in essence an azimuth thruster. The pod can rotate 360 degrees allowing for rapid changes in thrust direction and thus vessel direction. Continue reading

    Let’s get this rolling with:

    Ullage – The “Ullage” or “headspace” of a tank or vessel is the unfilled space left to be filled, and describes the empty space in large tanks or holds used to store or carry liquids –usually oil, but can be applied to bulk solids such as grain. Taking an ullage reading is the companion process to taking a “sounding”. However, where a sounding measures the depth of fluid from the surface to the bottom of the tank, an ullage value is the distance yet to be filled. Continue reading

    Vapours – Tankers, despite safety advances, still have the capacity to act as floating bombs. This is due to the “fire triangle”, and the fact that before a fire or explosion can occur, three conditions must be met simultaneously. A fuel (ie. combustible gas) and oxygen (air) must exist in certain proportions, along with an ignition source, such as a spark or flame. The ratio of fuel and oxygen that is required varies with each combustible gas or vapour. Continue reading

    Security – Shipping has long been vulnerable to attack, fraud and crime at sea, so the industry takes maritime security seriously. People, cargoes and vessels have an inherent value and so are attractive targets for terrorists, pirates, fraudsters and criminals. Different areas have different risks, but security is an increasingly important part of shipboard operations. Continue reading

    Radar – Radar is an “object-detection system” using radio waves to determine the range, angle, or velocity of objects. It can be used to detect any objects which reflect radio waves – so is particularly good at sea for identifying and monitoring other ships, land and even nearby weather. Continue reading
