    Ammonia as Marine Fuel: Is the Crew Ready?

    Ammonia as Marine Fuel: Is the Crew Ready? | OSSA LNG An ammonia alarm sounds. The engineers need to understand what the fuel system has done. The bridge needs to know whether propulsion is affected. The crew needs clear instructions. How well would those people work together on their own ship? This OSSA LNG episode explores ammonia as marine fuel through the practical questions facing seafarers, engineers and shipowners. Drawing on the My LNG article by Tadeusz Osowski, Chief Engineer, it examines how equipment, training and working arrangements need to come together before operations begin. IN THIS EPISODE • Ammonia’s toxicity and what it means for crew preparation. • Communication between the machinery space and the bridge. • Emergency drills that reveal problems while there is still time to correct them. • Whether the people available can carry out the duties assigned to them. • Coordination between the ship and its bunker supplier. • The responsibilities of designers, manufacturers, owners and managers. The episode also considers IMO’s interim ammonia training and safety guidelines, while keeping the focus on what those preparations mean during a working watch. For maritime professionals, students and anyone following shipping’s fuel transition, this is a practical look at the people and decisions behind bringing a new fuel into service. Listen for the questions worth asking before the next watch.

    One Ship, Different Clocks: UTC, Alarm Delays & Marine Investigations

    One Ship, Different Clocks: UTC, Alarm Delays & Marine InvestigationsEPISODE DESCRIPTION What does a timestamp really tell us after a machinery failure? Onboard a ship, local time, UTC and equipment clocks can describe the same moment differently—and an alarm may appear after the event that triggered it. In this episode of OSSA LNG, we explore how marine engineers and accident investigators reconstruct a reliable timeline from machinery logs, alarm histories and recordings. Starting with the decision to retire leap seconds, we examine the practical distinction between the time that organises life onboard and the time used to understand a technical failure. Two documented investigations bring the subject into focus: • Dali: how the US National Transportation Safety Board checked equipment time references and aligned shipboard and shore recordings using a shared recorded event. • Viking Sky: how alarms identifying the reason for generator shutdowns were registered approximately eight seconds after the shutdown alarms, complicating interpretation of the sequence. We also discuss local and UTC timestamps in Kongsberg K-Chief 600 documentation, configured alarm delays, and why the first alarm in a history does not necessarily identify the initiating fault. For marine engineers, electro-technical officers, technical superintendents and LNG professionals, the central question is practical: which event was recorded, against which clock, and at what stage of the sequence?

    The 2 barg LNG Membrane Tank Revolution

    Why Idle LNG Ships Build Pressure: The 2 barg LNG Membrane Tank RevolutionHost: MyLNG Engineering Channel: YouTube @ossati Target Audience: Marine engineering students, fleet operators, naval architects, and LNG fuel technology specialists. Episode SummaryWelcome to this special educational episode presented by MyLNG Engineering! In this episode, we tackle one of the most pressing operational dilemmas in modern cryogenic fuel management: why idle LNG-fueled ships build vapor pressure in port and how raising membrane fuel tank design pressure from the conventional 0.7 barg threshold up to 2 barg alters the thermodynamic equation. Have you ever wondered why connecting an LNG-fueled vessel to Onshore Power Supply (OPS) can suddenly complicate boil-off gas (BOG) management? Or why increasing a tank's allowable design pressure to 2 barg provides a larger operational window without eliminating thermodynamic heat ingress? We unravel the thermodynamics, structural load requirements under the IGF Code alternative design process, and classification approvals from ClassNK and DNV that every maritime engineer needs to master. Don't forget to subscribe to our YouTube channel @ossati for more deep dives into marine propulsion, LNG containment systems, and machinery space operations! What You Will Learn in This EpisodeThe Port Stay & Shore Power Dilemma:Why switching off auxiliary engines to plug into Onshore Power Supply (OPS) removes primary gas consumers onboard, transforming continuous heat ingress into rapid vapor pressure buildup.Thermodynamics of 0.7 barg vs. 1 barg vs. 2 barg:How increasing allowable relief valve settings (MARVS) from the atmospheric reference of 0.7 barg (~1.7 bar absolute) up to 2 barg (~3 bar absolute) expands the allowable pressure holding window without altering underlying boil-off rates.Alternative Design & Classification Approval:The step-by-step safety equivalence evaluation under the IGF Code required when exceeding 0.7 barg, including structural reinforcement against ~200 kN/m² differential pressure loads, fuel tank domes, gas handling, and hull integration assessed by DNV and ClassNK.Target Applications & Scaling Reality:Why 2 barg membrane containment is tailored for smaller fuel capacities on Pure Car and Truck Carriers (PCTCs), cruise liners (such as Le Commandant Charcot), and container feeders—and how it differs from the 1 barg Mark III Flex systems deployed on ultra-large container ships.Key Engineering TakeawaysPressure Holding is an Operational Envelope: Raising design pressure provides operational flexibility to store warmer bunkered LNG and delay active gas disposal, but it does not stop thermodynamic heat ingress or BOG generation.Shore Power Alters Onboard Energy Balance: Utilizing OPS cuts berth emissions, but requires an approved BOG management strategy (such as dual-fuel boilers or expanded holding time) when engines are offline.Follow Framework & Flag Approval: Exceeding standard 0.7 barg IGF Code limits requires a project-specific alternative design validation with Flag Administration and Classification Society sign-off.Connect With UsYouTube Channel: @ossatiProduced by: MyLNG Engineeringwww: mylng.art

    Why Cold Water Heats Up Turbochargers

    Why Cold Water Heats Up Turbochargers: The Diesel Exhaust Temperature ParadoxHost: OSSA LNG Channel: YouTube @ossati Target Audience: Marine engineering students, plant operators, and naval architecture professionals. Episode SummaryWelcome to this special educational episode presented by OSSA LNG! In this episode, we dive into one of the most counterintuitive phenomena in marine diesel engine operation: the Diesel Exhaust Temperature Paradox. Have you ever wondered why a stable 380°C cylinder-outlet reading on your dashboard doesn't reflect the actual temperature at the turbocharger turbine inlet? Or why injecting cold water during turbine wet cleaning can cause exhaust gas temperatures to unexpectedly spike? We unravel the thermodynamics, sensor physics, and coupled system responses that every marine engineer needs to master. Don't forget to subscribe to our YouTube channel @ossati for more deep dives into marine engineering, LNG technology, and machinery space operations! What You Will Learn in This EpisodeThe Measurement Paradox: Why cylinder-outlet sensors and turbine-inlet sensors measure fundamentally different gas dynamics, leading to reported differences of 100–140°C on identical engines.Sensor Thermal Inertia & The 720° Cycle: How a 4-stroke cycle (720° crankshaft rotation) with an exhaust valve open for ~300° creates intermittent hot gas pulses and scavenging cooling. You'll learn why thermocouple response times filter out rapid fluctuations into a calm, average reading on the screen.The Wet Cleaning Paradox: The step-by-step chain reaction of turbine wet-cleaning on engines burning Heavy Fuel Oil (HFO) or Marine Diesel Oil (MDO):Cold water absorbs heat and reduces exhaust gas energy reaching the turbine.Reduced turbine power drops turbocharger rotational speed and delivery pressure.Lower charge air pressure alters cylinder combustion, causing exhaust temperatures to rise.Governors attempting to hold fixed engine output inject additional fuel, exacerbating the thermal spike.Avoiding Catastrophic Thermal Stress: Why underestimating turbine inlet temperatures during washing can lead to hairline cracks, nozzle ring damage, flange distortion, and fluid leaks.Key Engineering TakeawaysDistinguish the Data: Never confuse local gas temperature, sensing-element temperature, and displayed indication.Measured vs. Estimated: A cylinder-outlet indication is a direct reading, whereas unmonitored turbine inlet conditions are at best an estimate—never take them as guaranteed facts.Follow Manufacturer Protocols: Field guidance ranges (like +100–140°C) are indicative baselines; always adhere strictly to specific equipment manual procedures before initiating wet cleaning.Connect With Us YouTube Channel: @ossati️ Produced by: OSSA LNG

    How Security Threats Are Redefining Global Energy Prices and LNG Supply

    Key Topics Shift to Structural Risk: How cyber intrusions, drone strikes, and sabotage have transformed energy security from a rare operational issue into a permanent variable shaping global pricing and investments.Cyber-Physical Convergence: How targeted malware (such as Triton) weaponizes industrial control systems and fail-safes to cause physical shutdowns remotely.Substitutability over Facility Scale: Why network resilience depends more on alternative routes, storage, and chokepoints than on a single facility's total export capacity.Non-Energy Supply Chain Dependencies: How shortages of critical processing inputs, such as specialized chemical solvents, can halt entire liquefaction trains.Two-Tier Market Reaction: How short-term spot gas prices and freight rates spike on unverified rumors, whereas long-term capital investments require verified evidence.The Securitization Dilemma: Why over-militarizing or publicly spotlighting infrastructure can inadvertently create targets, elevate insurance costs, and deter private investment.Evidence Matrix Discipline: The necessity of categorizing events—separating confirmed damage, reported incidents, allegations, and near misses—to prevent speculative market panic. Episode Description How do hybrid threats, cyber intrusions, and maritime security risks shape global energy markets? In this episode of Gas Under Pressure, we explore why energy security is no longer just about guarding physical perimeter fences, but about managing complex, interconnected LNG networks. We examine how cyberattacks targeting industrial safety systems—such as Triton malware—can cause physical disruptions from afar, and why a facility’s location at a critical chokepoint matters more than its export volume. The conversation breaks down the concept of substitutability, non-energy supply chain dependencies like specialized chemical solvents, and how unverified rumors create short-term volatility in spot prices and shipping freight rates. Plus, we analyze the securitization dilemma: why over-militarizing infrastructure can inadvertently raise insurance costs and deter private investment. Whether you are an energy professional or an informed listener, this episode offers vital insights into the resilience of global gas infrastructure.

    The Methane Princess Myth: What Really Happened in 1979?

    Every LNG engineer has heard the story: in 1979, the pioneer LNG carrier Methane Princess suffered a catastrophic explosion during a gas-freeing operation off the coast of Spain. It is a classic cautionary tale told in training rooms worldwide. But when you examine official flag-state reports, classification society records, and international maritime casualty databases, a surprising truth emerges — the explosion never actually happened. In this episode, we unpack how decades of oral safety training conflated the legendary vessel Methane Princess with a real 1979 land-based terminal explosion at Cove Point, Maryland. We explore why dramatic training myths take root and dive deep into the verified physical hazards that actually shape modern LNG safety engineering — from cryogenic steel embrittlement and thermal stress to electrical-arc ignition in hazardous zones. In this episode, you will learn: The Anatomy of a Maritime Myth: How training narratives drift over time, swapping land-based facilities with shipboard disasters.Fact vs. Fiction: The true operational history of Methane Princess, including its 1965 cryogenic deck-fracture incident and successful multi-decade service record.The Cove Point Reality: What actually occurred during the 1979 Cove Point terminal explosion caused by vapor migration into an electrical substation.Real Engineering Lessons: How historical accidents like Cleveland (1944), Portland (1969), and La Spezia (1971) established modern isolation, containment, and gas-freeing protocols.The Source-Checking Habit: Why watchkeepers and safety engineers must ground operational decisions in verified physical mechanisms rather than unproven anecdotes. Listen now to discover why checking your primary sources keeps ships and crews safe — and why the real engineering history of LNG is even more compelling than the legend!

    Boiling Liquid Expanding Vapour Explosion: The Hidden Physics of a BLEVE

    Imagine you are navigating rough seas, and your super-chilled liquefied natural gas (LNG) tank pressure suddenly drops. Relief? Think again. In marine thermodynamics, that falling pressure gauge might actually be a fatal warning sign of impending disaster. In this gripping, deep-dive episode we pull back the curtain on the ultimate maritime nightmare: a Boiling Liquid Expanding Vapour Explosion (BLEVE). Moving far beyond dry regulations, they decode the complex physics and human high-stakes choices that determine whether a gas-fuelled ship survives a cryogenic emergency. What you’ll discover in this episode: The Sloshing Paradox: Why ship motion does not just add physical stress, but actively rewrites tank thermodynamics—tricking crews with highly misleading "benign" pressure drops that mask escalating hazards. A Sequence, Not a Lightning Strike: Why a BLEVE is best understood as a progressive chain of events—from containment loss and rapid flashing to blast waves—offering critical, life-saving windows for intervention before a catastrophic rupture. The Automation Trap: Why standard IGF Code Chapter 19 training fails when it relies on static checklists, and how the cognitive load of modern Emergency Shutdown (ESD) systems can overwhelm crews during real-world, compound emergencies. The Barrier Blueprint: How combining thermal monitoring, active fire protection, and rapid manual isolation forms a complete, unbroken shield against disaster. Whether you are a marine engineer, safety professional, seafarer, or simply fascinated by extreme physics and industrial safety, this episode is an essential guide to the thin line between controlled cryogenic power and explosive thermal runaway. Hit play now to uncover the invisible forces threatening gas-fuelled ships and learn how modern crews can stop a catastrophe before the first spark.

    Who Protects Seafarers When Missiles Strike? Maritime Law & Conflict Zones

    When merchant ships enter war zones, who truly protects the crew? In this episode, we examine the critical gaps in international maritime law facing seafarers navigating high-risk waters like the Red Sea, the Strait of Hormuz, and the Black Sea. While missiles and dornes target commercial shipping, crew protections remain fragmented, reactive, and dependent on a "contractual lottery". In this episode, we cover: The Institutional Gap: Why current actions by the International Maritime Organization (IMO) and International Labour Organization (ILO) remain largely advisory rather than enforceable.The Contractual Lottery: How seafarers facing the exact same military risk on identical routes end up with vastly different rights to danger pay, repatriation, or voyage refusal depending on their contract.Shadow Fleets & Evasive Operations: How opaque ownership, manipulated tracking, and lack of insurance exacerbate crew vulnerability and undermine accountability.A Enforceable Solution: The urgent policy proposal for a Joint IMO-ILO Emergency Protocol that guarantees automatic, pre-voyage rights—including the universal right to refuse war-zone voyages without retaliation, mandatory repatriation, minimum danger pay, and protection for Ship Masters. As military threats at sea escalate, protection must become automatic before a vessel sails—not symbolic after a tragedy occurs. Keywords Primary Keywords: Seafarer rights, Maritime security, Conflict zones shipping, IMO ILO emergency protocol, Danger pay seafarers, Red Sea missile attacks, Shadow fleet risks Secondary Keywords: Merchant navy war zones, Maritime Labour Convention MLC, ITF IBF agreements, Ship master protection, Mandatory repatriation seafarers, Maritime law reform, Black Sea commercial shipping Hashtags #MaritimeSecurity #SeafarersRights #ShippingIndustry #IMOMaritime #MaritimeLaw #RedSeaCrisis #SeafarerSafety #SupplyChain
