Ammonia fueled engines it the biggest mistake in maritime world that is happening right now. Seafarers should not be a suicide squads in ER. Risk assessments won’t help against fatalities of this toxic gas when it leaks in ER. These vessels have to be BANNED! Look at this picture. It shows the leak of Propane Butane near LGIP DualFuel ME. 18% LEL. And no one cares because owners want’s vessels to run! If you agree - please react to this comment and share. We should stop this Ammonia fuel in ER! https://www.linkedin.com/feed/update/urn:li:activity:7447206136480620544?commentUrn=urn%3Ali%3Acomment%3A%28activity%3A7447206136480620544%2C7447277156512006144%29&dashCommentUrn=urn%3Ali%3Afsd_comment%3A%287447277156512006144%2Curn%3Ali%3Aactivity%3A7447206136480620544%29

💸 “How Much Is an ETO Worth in 2026?” In 2026, the offshore market is… let’s say, an interesting place. One ETO is paid $300 per day, another gets $700. And no — the difference is not always about who is more competent. Sometimes it’s just about who sounds more experienced in an interview. Everyone loves writing: 10+ years experience, DP2 vessel, Chief ETO. Looks impressive. Almost like a guarantee that the guy will walk in and save your vessel. Then reality hits — and the only thing he consistently saves is himself from extra work. There’s a special category of professionals whose main principle is: “If it works — don’t touch it. If it doesn’t work — don’t touch it either, it might fix itself.” And yes, some of them are actually getting paid pretty well. Meanwhile, somewhere on the same vessel, there’s a guy who actually understands what’s going on. The one who can rebuild a system overnight, restore power, bring automation back online, and make it all look like “nothing ever happened” by morning. And somehow… he’s not getting paid that much more. Because the #offshore market is not always about competence. It’s often about timing, luck, and how well you sell yourself. What’s even more ironic — expectations keep growing every year. Now an #ETO is expected to be an electrician, an automation engineer, a bit of an IT specialist, and occasionally a mind reader who can diagnose a fault just by hearing a relay click. But the pay? Still mostly “electrician level.” With a small bonus for stress. And that’s the paradox of 2026: systems are more complex, responsibility is higher — but the way people are valued hasn’t really changed. In the end, it comes down to one simple thing. Your value is not your experience, not your certificates, and not even your real skills. Your value is how replaceable you are. ❗If you can be replaced tomorrow — you’re worth $300. If the vessel starts panicking without you — you’re worth whatever you decide to ask for. So the real question isn’t about the market. The real question is about you. 👉 How much are you really worth? ✍️ Author: https://www.linkedin.com/posts/activity-7445346777656111105-DZkF?utm_source=share&utm_medium=member_ios&rcm=ACoAAC_V_QgBkUHCmF3qxcHLZnTm3M8vV93a4kw

❇️ UNDERSTANDING POWER FACTOR 🍻 Beer is active power (kW) - the useful power, or the liquid #beer, is the energy that is doing work. This is the part you want. 😶‍🌫️ Foam is reactive power (kVAR) - the foam is wasted power or lost power. It’s the energy being produced that isn't doing any work, such as the production of heat or vibration. 🍺 The mug is apparent power (kVA) - the mug is the demand power, or the power being delivered by the utility. #activepower #kW #power #reactivepower #kVAR #energy #heat #vibration #apparentpower #kVA

On March 10, 1891, Nikola Tesla received a patent for an alternating current (AC) generator—one of the key inventions that helped shape modern electric power systems. What this generator was It was a machine designed to produce alternating electric current (#AC). At the end of the 19th century, the world was in the middle of the “War of Currents,” a rivalry between supporters of direct current (#DC) and alternating current. Tesla’s generator became a crucial part of AC’s eventual victory. Why it was revolutionary Before this, direct current systems were widely used, but they had a major limitation: • Electricity could only be transmitted over short distances • Power stations had to be built very close to consumers Alternating #current solved these problems. Key advantages of the AC generator 1. Long-distance power transmission #AC voltage can be easily stepped up or down using transformers, allowing electricity to travel hundreds of kilometers with minimal losses. 2. Efficiency and lower cost Fewer power plants were needed, and electricity became cheaper. 3. Foundation of modern power grids Today, almost the entire world uses alternating current in homes and industry. How Tesla’s generator worked The #generator created a rotating magnetic field, which induced alternating current in the windings. This same fundamental principle is still used in modern power plant #generators. Historical significance The 1891 patent became a major step toward: • Large power stations • #Electrification of cities • The creation of global power networks Without Tesla’s work, the electrified world we know today would look very different. #NikolaTesla #Tesla

This is the truth and there is nothing more to say 😢 For years, ships quietly moved 90% of the world's goods. No noise. No attention. But the moment things get disrupted... everyone starts talking. Funny how some industries stay invisible until they become essential. 🫡 Respect The Ones Who Keep The World Moving. #seafarers

The letters on fuses follow #IEC 60269 categories. They tell you what the fuse protects and how fast it reacts. The first letter = breaking range (what fault currents it can interrupt). The second letter = application (what equipment it protects). #gG fuse — General purpose (the “normal” fuse) Full name: general purpose, full-range fuse This is the standard #fuse used in distribution boards and industrial panels. What it protects • #Cables • #Wires • #Lighting circuits • #Heaters • General equipment It protects against: • #Overload (small overcurrent for long time) • #Shortcircuit (huge current instantly) So it covers both slow and fast faults. Typical use • Main distribution boards • Control panels • Feeders • Cable protection Think: “gG = general use fuse.” #aM fuse — Motor protection fuse Full name: accompanying Motor fuse This fuse is special and often misunderstood. It protects ONLY against short circuits, NOT overloads. Why? Because #motors have huge starting current (6–10× rated current). A normal fuse would blow every time the #motor starts. This is why the name starts with a = accompanying. It must be used together with a motor overload relay. Typical use • #Motor starters • #Pumps • #Fans • #Compressors • #Conveyor motors Think: “aM = motor fuse partner.” If you use aM alone → motor can burn from overload. #gI fuse — Semiconductor / ultra-fast fuse Full name: general purpose for semiconductor protection These are very fast fuses designed for electronics that die in milliseconds. Semiconductors (IGBT, thyristors, diodes) cannot survive the time delay of gG fuses. So gI fuses are: • Ultra-fast • Very sensitive • Expensive What they protect • #VFD drives • #UPS systems • #Rectifiers • #Inverters • Soft starters • Power electronics Think: “gI = instant protection.” Real-world examples (ship/industrial) • Lighting feeder → gG • Pump motor starter → aM + overload relay • Frequency converter / VFD → gI Simple analogy • gG = Bodyguard for the whole building • aM = Security for the motor’s emergency only • gI = Surgeon protecting fragile electronics

The term CPP shaft propeller refers to a #ControllablePitchPropeller system installed on a ship’s propulsion shaft line. It’s widely used on vessels that need flexible speed and thrust control (e.g., offshore #vessels, ferries, tugs). What is a CPP? A Controllable Pitch Propeller is a propeller where the blade angle (pitch) can be changed while the shaft is rotating. • Fixed Pitch Propeller (FPP): blade angle is constant • CPP: blade angle can be adjusted during operation Main Components of a CPP #Shaft System 1. #Propeller Hub • Contains the pitch-changing mechanism • Blades are mounted on #bearings and can rotate around their own axis 2. Blades • Adjustable angle • Change thrust direction and magnitude 3. Shaft Line • Transmits torque from the main engine to the propeller • Includes: • Intermediate shaft • Stern tube • #Bearings 4. #Hydraulic System • Oil under pressure is used to rotate blades • Controlled from bridge or engine control room 5. #Servo Mechanism (Inside Hub) • Moves blades via: • Piston • Linkages or crank rings 6. Oil Distribution System (#ODS) • Transfers hydraulic oil from stationary piping to rotating shaft • Usually via: • Oil distribution box (#OD box) • Hollow shaft How It Works 1. #Engine runs at constant #RPM 2. Operator changes pitch angle 3. Hydraulic oil moves piston inside hub 4. Piston rotates blades: • Ahead pitch → forward thrust • Astern pitch → reverse thrust • Zero pitch → no thrust Advantages of #CPP • Smooth speed control without changing engine RPM • Instant reversing (no need to stop engine) • Better maneuverability (important for port ops) • Fuel efficiency at varying loads Disadvantages • More complex than #FPP • Higher maintenance (hydraulics, seals, hub internals) • Risk of oil leakage (environmental concern) Where You’ll See CPP • #Offshore supply vessels • #Tugs and harbor vessels • Ferries • #Dynamicpositioning (#DP) ships
