Smart Pressure Transmitters Drive Growth in the Maritime Industry

Background

Driven by increasingly stringent global environmental regulations, the maritime sector is rapidly transitioning from traditional fuel oils to Liquefied Natural Gas (LNG) and other clean energy alternatives. Utilizing LNG as marine fuel reduces carbon emissions by over 20%, eliminates sulfur oxides (SOx) completely, and reduces particulate matter (PM) emissions by more than 90%.

As part of China's inland vessel retrofit initiative, a shipping operator converted its fleet of container vessels to LNG power. Operating deep within the fuel supply systems, highly reliable pressure monitoring is vital to ensure the safe and efficient delivery of LNG under extreme working conditions.

Application Challenges

Transitioning a vessel from conventional fuel oil to LNG involves complex engineering. The physical properties of LNG present unique operating challenges for pressure measurement instruments:

•Severe Mechanical Vibration & Signal Drift: Engine vibration and vessel motion at sea frequently lead to signal instability and measurement drift in standard pressure instruments.

•High Explosion Risk: LNG is highly flammable. Fuel tanks, piping manifolds, and key supply nodes demand stringent explosion-proof safety standards.

•Harsh Corrosive Environments: Marine environments expose instruments to continuous salt spray, high humidity, and sea splash, leading to rapid corrosion and degradation.

The Solution

To address these technical hurdles, the customer selected Micro Sensor’s MDM7000-DP (Differential Pressure) and MDM7000-GP (Gauge Pressure) smart pressure transmitters for critical system monitoring:

•Superior Vibration Resistance: Featuring vibration effect specs below 0.1%, the transmitters maintain standard high accuracy of ±0.075% F.S. even under severe dynamic conditions.

•Certified Flameproof & Intrinsically Safe: Certified under multiple global hazardous location standards, ensuring reliable and safe operation around flammable gases.

•Robust Enclosure & Corrosion Protection: Rated IP67 and passed WF2 anti-corrosion testing, ensuring long-term endurance against salt fog and harsh marine atmospheres.
