We are SIL RATED          

At NSW mines and petroleum sites it is mandatory that electrical safeguards must have sufficient reliability for the level of risk being controlled.

IEC61508 (SIL), AS61508, AS62061, ISO13849, AS4024.1, AS61511 and other standards provide a process for doing this. In conformance to the MDG43 and NSW department requirements, it is mandatory that safety-related functions  arising from hazard assessments must be assessed by an appropriate functional safety standard such as SIL (Safety Integrity Level), PL (Performance Levels) or CAT (Categories) or other relevant functional safety standards.

Nautitech gets SIL Rated

Nautitech believes in the integrity of the SIL process, and feels strongly that its existence enhances the systems Nautitech manufactures for its customers. Many factors come into play in harsh environments impacting upon the longevity of some products. So we believe by being independantly SIL assessed, our customers are ensured safety of the highest standard.

As SIL is demanded by the market, Nautitech accepts it, will manage it, and get it done.

So far we have the following systems externally SIL rated:

•  Torque
•  Methane Master
•  Electrical Methane Master
•  The Jug systems
•  The GE Mining C9 System

What is a SIL rating?

Safety integrity level (SIL) is a measure of the likelihood that a system performs its nominated safety function when required. SIL ratings apply to each safety function performed by a system.

Individual components may have SIL ratings and these contribute to the overall SIL rating of a safety function.

SIL Certificate

Our SIL certificates are issued as a summary of the hardware failure data affecting the application of the equipment as a sub-system being part of a Safety Function intended to conform with the requirements of IEC61508 – Functional Safety of Electrical/Electronic/ Programmable Logic Safety Systems.

Temperature Electronic Engines Temperature Diesel Engines Oil Pressure Electronic Engines Methane Electronic Engines Methane Diesel Engines Emergency Stop Electronic Engines

Please note our SIL certificates refer to the hardware integrity aspects of the products – the probability of failure and the hardware architectural features. Systematic integrity including software safety integrity is not covered.

SIL Assessors

Being externally assessed ensures that our systems are accurately SIL certified so we only use the best in the business. In order to achieve our SIL ratings, we commissioned two external assessors to rate our hardware:
