Safety and compliance through precise cargo hold temperature monitoring in bulk carriers – in line with the IMSBC Code and SOLAS. With the CargoTemp Roller, SIKA provides the proven solution for ship crews and operators.
✅ Complies with IMSBC Code temperature limits
✅ Documentation for RightShip and PSC inspections
✅ Operational safety through self-tests and signal monitoring
In shipping, evidence is mandatory. PSC authorities and RightShip inspections require verifiable documentation of cargo hold temperature monitoring. Key questions include:
- Are IMSBC Code temperature limits observed?
- Are measurements taken in different holds and at multiple points?
- Is monitoring performed regularly and consistently?
Experience shows: Transparent records speed up inspections and help avoid costly detentions or cargo refusal.
Coal Cargo Temperature Monitoring on Ships
Coal can self-heat within the cargo hold – particularly low-rank or lignite-type coal – raising temperatures and greatly increasing the risk of fire or explosion. The IMSBC Code mandates that coal exceeding 55 °C must not be loaded, as self-heating accelerates rapidly in oxygen-rich environments.
Grain Cargo Temperature Monitoring
Grain and oilseeds are prone to fermentation, mold growth, and condensation, especially when exposed to heated structures such as steam pipes or heated tanks. Even moderate temperatures between 40 °C and 55 °C can cause substantial quality loss, particularly under high moisture or inadequate ventilation.
DRI Cargo Temperature Monitoring (IMSBC Code)
Direct Reduced Iron (DRI) is known to react vigorously upon contact with moisture, potentially generating high temperatures and releasing hydrogen – thus elevating the risk of explosion. Temperature increases of up to 30 °C above ambient have been documented after handling. The IMSBC Code requires strict ventilation and monitoring procedures for DRI, especially for Types C and D.
Other Bulk Cargoes
For Monitoring
Other bulk cargoes – such as fertilizers, ores, or oil pellets – carry similar hazard profiles: moisture-induced reactions, dust emissions, or chemical heat generation can lead to heat buildup, gas release, or load damage. Only comprehensive cargo hold temperature monitoring ensures complete safety and adherence to IMSBC standards.
- Coal: max. 55 °C before loading
- DRI: max. 650 °C
- Other bulk cargoes: specific limits according to IMSBC Code
These values must be monitored and documented to prove compliance.
Fixed sensor systems inside cargo holds are costly and difficult to retrofit. Crews and ship operators therefore rely on portable cargo hold thermometers, which:
- can be used flexibly in different holds,
- ensure maximum safety,
- work reliably and maintenance-free even under harsh conditions.
The CargoTemp Roller combines easy handling with high measurement accuracy – and has become the global standard solution for inspections and routine checks.
Digital thermometers
Type CargoTemp Roller ETC
Precise temperature monitoring in the cargo hold up to 150°C. With Pt1000 sensor, large LCD, 35 m temperature- and oil-resistant FEP cable (with depth markings every 5 m), up to 50 N tensile load, battery-powered (display side) with up to 10 years service life – ideal for safe, compliant use in bulk carriers under demanding conditions.
What IMSBC temperature limits apply to coal?
Coal must not exceed 55 °C before loading.
Is regular temperature monitoring mandatory?
Yes – the IMSBC Code and SOLAS require continuous monitoring and proper documentation.
Which cargoes are most critical?
Coal, DRI, grain, oilseeds, and fertilizers – all covered under the IMSBC Code.
Is the CargoTemp Roller officially recognized?
Yes – it supports operators worldwide in meeting IMSBC, SOLAS, and inspection requirements.
Does the CargoTemp Roller perform automatic self-tests?
Yes. On start-up the device automatically checks the sensor and continuously monitors the signal for plausibility. Errors such as a sensor break are shown on the display. The CargoTemp Roller is also maintenance-free.
