Hazardous Areas Classification on Ship (Examples and explanation by Rules)
It’s will be a long and confusing contents through all the requirement from IEC/IECEx as well as IMO (SOLAS, IBC, IGC codes). Thus, i’ll make it as short as possible to make the article with key knowledge & understanding. FIRST … Continue reading Hazardous Areas Classification on Ship (Examples and explanation by Rules)
Intrinsically Safe Cable
Intrinsic safety – I.S is a protection technique for the safe operation of electrical and electronic equipment/system in Hazardous Areas where any ignition source needs to be eliminated. Electrical cables are essentially sealed from damage, external electrical or magnetic fields (EMI), and isolated from non-intrinsically safe circuits. (Avoid the increase of amperes mA in I.S system –> A –> Hot spot –> Ignition -> Explosion ) I.S cables are usually colored blue so as to identify the potential risk of the electric circuit and the need for special consideration. The I.S cable to be separated from Non-I.S circuits. Hazardous areas is the … Continue reading Intrinsically Safe Cable
Sheer Strake – An important plate of ship
This topic is an additional knowledge support for SHIP STRENGTH CALCULATION (Part 1) and SHIP STRENGTH CALCULATION (Part 2). Under sea-going condition, the Hogging and Sagging condition make the ship steel be continuously compressed and stretched those making steel become fatigue collapsed specially … Continue reading Sheer Strake – An important plate of ship
Design draft vs Scantling draft
The Draft, as simple definition is the distance between the sea level and the bottom of hull (included the thickness of bottom – see this topic) Meanwhile, at the initial design stage, there are two terms of Scantling & Design … Continue reading Design draft vs Scantling draft
Ship noise and vibration control
Vibration is a complex phenomena happen on ship and machinery space, to understand and have the first sight of vibration assessment or further development, the fundamental of vibration theory is the great article for your pre-learning with such concept. In this topic, i’ll try to make it it as simple as possible to know-how the vibration analysis and modeling solutions in engineering term. As defined, any motion that repeats itself after an interval of time is called vibration or oscillation. 1st Basic modeling objects A vibratory system, in general, includes a means for storing potential energy – thế năng (spring or … Continue reading Ship noise and vibration control
