    "Ammonia-Ready" Ships Explained: LNG Bunkering & Safety

    If a ship is labelled “ammonia-ready”, what is actually ready—the tank, the engines, or the crew? Explore what it takes to move from an LNG vessel concept towards safe ammonia service, and why the answer involves much more than choosing the right steel. Using Hanwha Power’s 22,000 m³ LNG bunker vessel concept, OSSA LNG breaks down Approval in Principle (AIP), ammonia safety and hybrid marine power in clear, practical terms. A hypothetical shore-power failure brings the engineering to life: how could batteries and generators support essential services, what protection must remain available, and what would the crew need to do? Whether you study marine engineering, work at sea or are curious about alternative marine fuels, listen to discover the questions worth asking behind an “ammonia-ready” headline—including the difference between carrying ammonia, supplying it to another ship and burning it as fuel.

    How a Tiny Fitting Shatters LNG Ships

    How can a small temperature pocket become a cargo-containment problem on an LNG carrier? In this OSSA LNG episode, we follow the liquid cargo from the terminal connection to the ship’s tanks, then examine the thermowell: the protective pocket that separates a temperature sensor from flowing LNG. We explain where this component fits into the installation, why temperature is measured there, and how flow-induced vibration and repeated bending can contribute to fatigue failure. A fractured thermowell can leave a detached fragment inside the cargo system. If its wall is breached, LNG may enter the sensor cavity; whether it escapes outside depends on the remaining sealing arrangement. We also examine SIGTTO’s historical account of leakage associated with cryogenic deck fracture, while recognising the limits of the published evidence. The central lesson: a normal temperature reading does not confirm that the thermowell is intact or leak-tight. Designed for maritime students, cadets and engineers who want to connect component design with the practical realities of shipboard systems.

    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!
