LNG project development rarely struggles because of technology; it struggles because of decisions made during design, construction, commissioning, and start-up, often years before first gas flows. That is the consistent lesson the engineers at Alaska LNG Services LLC have taken from careers spanning liquefied natural gas (LNG), cryogenic facilities, oil and gas, chemical, air separation …

Many LNG plants are leaving production on the table because Joule-Thomson valve (JTV) and expander performance problems have been quietly accepted as normal. Compressors, gas turbines, and Main Cryogenic Heat Exchangers (MCHEs) receive exhaustive specification and performance testing—while the valves and expanders equally critical to production are rarely scrutinized at all. That asymmetry is where …

Routine flaring at an LNG plant is usually a symptom, not the root cause—the flare is telling you something about process control, equipment performance, and unit operation upstream of it. That is how the engineers at Alaska LNG Services LLC read a flare, and it changes where you look for the fix. The flare itself …

An LNG carrier is proven during sea trials and gas trials, not at the shipyard berth. Before a newbuild LNG carrier (LNGC) enters commercial service, every propulsion, cargo, auxiliary, and safety system must demonstrate—under witness—that it performs to the build specification and complies with the international rules the vessel will sail under. This case study …

Many countries have stringent regulations against the use and importation of asbestos.  e.g. Australia enforces a zero-tolerance ban on asbestos and any facility entering Australian waters must prove it is asbestos-free, not merely declare it. All forms of asbestos have been banned in Australia since December 31, 2003—import, manufacture, use, and sale—and at the border …

Proving marine assets can operate year-round in Arctic sea ice takes more than analytical modeling—it takes full-scale ice trials, instrumented hulls, and measured ice properties. That is how the engineers at Alaska LNG Services LLC approach cold-climate marine work, and this anonymized project from our engineers’ careers shows what the method looks like in practice. …

Governing Bodies: IMO, IACS, and National Regulatory Frameworks LNG marine assets are subject to a comprehensive framework of statutory regulations and classification requirements that govern their design, construction, and operation. These include international conventions set by the International Maritime Organization (IMO), national regulatory frameworks, and classification standards established by members of the International Association of …

Pre-Commissioning vs. Commissioning: Why the Distinction Matters LNG commissioning and startup represent one of the most critical phases in the project lifecycle, where the transition from construction to live operations introduces significant technical and operational risk. Distinctions between pre-commissioning and commissioning activities must be clearly managed, as errors during this stage can lead to schedule …

The interface between LNG carriers and onshore facilities represents one of the highest-risk areas in LNG operations. Ship-to-shore systems must safely manage vessel motion, cryogenic transfer, and dynamic operating conditions while maintaining full compliance with international and national regulatory frameworks. We offer LNG project insights and analysis to manage this process. Our marine LNG engineering …

Process control and automation systems are fundamental to the safe, stable, and efficient operation of LNG facilities. Distributed Control Systems (DCS), PLC-based safety systems, and integrated automation platforms must perform consistently across all operating conditions, including startup, normal operation, turndown, and shutdown. They can offer the Alaska LNG engineering insights you need to keep an …
