1. Industry Service Background
Global shipping capacity of LNG-powered oil tankers, LPG liquid cargo carriers, and refrigerated container ships keeps expanding rapidly. Conventional fuel vessels face fire & explosion hazards, while LNG/LPG ships add extreme low-temperature frostbite risks. Traditional manual patrols suffer from blind inspection zones, delayed fault detection, and limited full-range temperature measurement.
We provide integrated standardized thermal imaging services: MSB Main Switchboard & ESB Emergency Switchboard electrical thermal inspection + LNG/LPG tank & pipeline cryogenic leak detection. The NKTEVA6 distributed thermal array detector delivers non-contact, visualized, wide-range hidden hazard screening, fully adaptable to predictive maintenance for all offshore & coastal marine vessels.

2.3 Oil Tanker Structural Compliance Rules
Per MARPOL Annex I Amendments, single-hull oil tankers were globally phased out starting 2015; all active vessels adopt double-hull / double-bottom hybrid structures. Infrared inspection is required for double-hull interlayers to detect leakage and pipeline overheating risks.
3. Critical Vessel Hazards (Why Thermal Imaging Inspection Is Mandatory)
3.1 Fire & Explosion Hazards of Oil Tankers
Interlaced pipelines & enclosed cabins generate dense high-temperature toxic smoke during fire, forming 3D connected combustion zones. Fast heat conduction of steel hulls easily triggers chain explosions of adjacent cargo tanks
Ballast / empty tank navigation carries higher risks than full cargo tanks: residual oil & gas mixed with air reaches LFL(1%)~UFL(10%) explosive range; static electricity, circuit short circuits, hot work may ignite blasts
Heavy crude oil generates unstable flame during combustion; water-containing crude causes boil-over splashing, leaked oil spreads across sea surface leading to severe marine pollution
Main ignition triggers: collision & grounding, open flame operations, circuit short-circuit, static accumulation, overheated machinery in engine room
3.2 Unique Cryogenic Explosion Risks of LNG / LPG Vessels
LNG operates at 1bar / -162°C storage pressure-temperature; LPG tanks run at 10bar / -20°C. Factory-installed only 8 thermocouples provide limited single-point temperature monitoring. Tiny leaks rapidly vaporize into ultra-low temperature gas, causing crew frostbite and flammable gas accumulation. Thermal imaging captures full-area temperature difference to visualize invisible leak points.

8. Frequently Asked Questions (FAQ)
Q1: Can thermal imaging accurately detect tiny LNG & LPG cryogenic leaks? What is the working principle?
A1: Yes, 100% effective. LNG/LPG cargo temperature is far lower than ambient temperature; vaporized leakage zones form distinct low-temperature color blocks on thermal images. Compared with limited 8 fixed single-point thermocouples onboard, NKTEVA6 thermal array scanners deliver wide-area visualized coverage with zero blind zones to pinpoint micro leakage points accurately.
Q2: What electrical hidden hazards does MSB & ESB thermal inspection identify?
A2: Special thermal survey for Main Switchboard (MSB) and Emergency Switchboard (ESB) targets loose busbar terminals, cable overload, aging contactors, motor overheating, circuit short circuits & emergency power overheating. It eliminates major fire risks caused by electrical ignition of flammable gas, and is a mandatory preventive inspection item for marine statutory safety checks.
Q3: What is the recommended thermal imaging inspection frequency for different vessel types?
A3: Standard container ships / bulk carriers: 1 full-vessel inspection per year; High-risk liquid cargo vessels including VLCC oil tankers, LPG & LNG carriers: specialized thermal inspection every 6 months; Aged ocean-going vessels & frequently loaded/unloaded vessels are advised to add quarterly re-inspection.
Q4: Do we need to empty oil tanks / LNG storage tanks or suspend cargo loading/unloading during thermal inspection?
A4: No requirement. Thermal imaging adopts long-distance non-contact temperature measurement technology; inspection can proceed normally when vessels are fully loaded, ballasted, or berthing for cargo operation, without occupying vessel operation time windows.
Q5: Can inspection reports pass port state control & classification society safety audits?
A5: All inspection engineers hold ITC international infrared thermography certification, all testing instruments carry valid metrological calibration certificates. Inspection reports fully comply with international maritime standards, directly available for vessel safety inspection & annual maintenance archive filing.
Q6: Which domestic ports support on-site door-to-door thermal inspection service?
A6: On-site 24-hour service available for all major coastal & inland river ports across China: Guangdong (Guangzhou, Shenzhen, Zhuhai, Zhanjiang, Maoming), Yangtze River Delta (Shanghai, Ningbo, Zhoushan, Jiangyin, Zhangjiagang), Bohai Rim (Tianjin, Qingdao, Dalian, Qinhuangdao), Fujian (Xiamen, Fuzhou, Quanzhou), Hainan (Haikou, Yangpu, Sanya), Guangxi (Beihai, Qinzhou, Fangchenggang) with resident inspection teams covering over 200 harbors.
Q7: Which onboard zones are suitable for fixed NKTEVA6 thermal detector installation?
A7: Priority installation locations: outer wall of full-containment LNG storage tanks, LPG pump rooms, MSB main electrical switch rooms, engine room high-temperature machinery zones, cargo pump rooms and other high-risk explosion-proof areas, for 24-hour continuous online monitoring with automatic early warning upon leakage or overheating faults.
