Queensland marine biologists have found that the damage sustained to a Filipino coral reef from an American warship is more extensive than first thought.
Analysis of Properties of Thrust Bearing in Ship Propulsion System
thrust bearing thrust pad lubrication properties ship propulsion shaft geometrical factors
2011/9/9
Thrust bearing is a key component of the propulsion system of a ship. It transfers the propulsive forces from the propeller to the ship’s hull, allowing the propeller to push the ship ahead. The perfo...
Research on the dynamic performance of ship isolator systems that use magnetorheological dampers
magnetorheological fluid damper vibration reduction shock resistance isolator
2011/9/13
Isolator systems on ships should ideally be able to simultaneously reduce low frequency vibration response and high frequency shock response. Conventional isolator systems are unable to do so. To solv...
Application of a compound controller based on fuzzy control and support vector machine to ship’s boiler-turbine coordinated control system
ship boiler-turbine coordinated system support vector machine inverse control compound control
2011/9/9
Multivariables, strong coupling, nonlinearity, and large delays characterize the boiler-turbine coordinated control systems for ship power equipment. To better deal with these conditions, a compound c...
Further Studies of a Cold Eddy on the Eastern Side of the Gulf Stream Using Satellite Data and Ship Data
Gulf Stream Satellite Data Cold Eddy Ship Data
2009/2/23
A cold eddy was observed in late March and early April 1975 to encounter the eastern boundary of the Gulf Stream and entrain warm Gulf Stream water into its outer fringes. Available evidence indicated...
Average Seasonal Variation of the Atlantic Equatorial Currents from Historical Ship Drifts
South Equatorial Current Seasonal Variation Historical Ship Drifts
2009/1/20
Surface currents in the tropical Atlantic were studied using historical ship-drift data. These are the only available data capable of resolving the long-term seasonal fluctuations of currents over a b...
