By Dez Duran-Lamanilao Atlantic sea scallops are sustainably managed in the US and fishermen harvest them responsibly by adhering to existing US regulations, thus minimizing bycatch in the process. They are available year-round, having an above target population level. Scallop boats are designed specifically for these species. Sizes of these boats vary, from 70 to […]

By Dez Duran-Lamanilao From misuse to old age to lack of proper maintenance, a lot of factors can cause hydraulic cylinder failure and in worse cases, may eventually result to ship breakdown. Depending on the gravity of the situation, boat owners will have to decide whether to repair the cylinder or remanufacture it, if the […]

By Dez Duran-Lamanilao Hydraulic actuators are mainly used to convert pressure energy of the fluid into mechanical energy. They may be classified as linear (for hydraulic cylinders), rotary (for hydraulic motors), or semi-rotary (for limited angle of actuation). A ship operates in three key systems, namely hydraulic, pneumatic, and electronic. An actuator helps a specific […]

By Dez Duran-Lamanilao Fluid power is a key contributor in the overall energy efficiency of various applications, such as hydraulic pumps with electric drives, intelligence-embedded valves, and even actuators and actuator controllers with electro-hydrostatic actuation (EHA) technology. Fluid power is known to have the highest power density when compared to other conventional power-transmission technologies. There […]

By Dez Duran-Lamanilao The potential of energy storage is ever increasing as technologies become more advanced and more appropriate and the advent of energy storage systems (ESS) begins to gain attention. The Virtual Energy Store of Upside Energy, for example, in collaboration with Heriot-Watt University, is expected to utilize machine learning and distributed artificial intelligence […]

By Dez Duran-Lamanilao Mobile machinery or mobile equipment, require industrial sensors that can withstand the test of time and abuse caused by various factors, including shock and vibration, extreme temperatures, and corrosive substances or chemicals. A truck-mounted crane for example, can perform better if equipped with magnetic sensor for hydraulic cylinder, capacitive joystick sensor for […]

By Dez Duran-Lamanilao Using a load-sensing hydraulic control system can help adjust the pressure and flow rate of an industrial equipment. Using LS control, sometimes known as power matching control, will adjust the output flow, thus maintaining a constant pressure drop across an orifice. An orifice can be a flow-control valve, a needle valve, a […]

By Dez Duran-Lamanilao Image source: ExxonMobil Fluid cleanliness is of primary importance to hydraulic systems because the risks associated with contaminants vary: from parts malfunction to wear and tear in components, to longer response times of your system’s key parts, valves to cite an example, among many others. Fluids can be classified as petroleum-based (mostly […]
