Fault Simulating Test Bed for Developing Diagnostic Algorithm of the Geared Rotating Machinery of Ships

Journal of Marine Science and Engineering
To prevent critical failure of the functional machinery of a ship, condition monitoring technologies have been much studied in recent times. In this respect, securing a fault database is a top priority in technology development.

Preconditioning and triggering of offshore slope failures and turbidity currents revealed by most detailed monitoring yet at a fjord-head delta [PDF]

, 2016
Rivers and turbidity currents are the two most important sediment transport processes by volume on Earth. Various hypotheses have been proposed for triggering of turbidity currents offshore from river mouths, including direct plunging of river discharge,

A Xenon Condenser with a Remote Liquid Storage Vessel

, 2009
We describe the design and operation of a system for xenon liquefaction in which the condenser is separated from the liquid storage vessel. The condenser is cooled by a pulse tube cryocooler, while the vessel is cooled only by the liquid xenon itself ...

Review on Boil-Off Gas (BOG) Re-Liquefaction System of Liquefied CO₂ Transport Ship for Carbon Capture and Sequestration (CCS)

International Journal of Air-Conditioning and Refrigeration, 2016
This paper presents the review on the boil-off gas re-liquefaction system of liquefied CO2 transport ship for carbon capture and sequestration (CCS). It is assumed that liquefied CO2 is transported between South Korea and Middle East for enhanced oil recovery (EOR) and enhanced gas recovery (EGR), which is similar to the oil and LNG transportation ...
