Small Scale Safety Link

The bunkering of environmental or cryogenic liquids and gases from ships requires a linked Emergency Shut Down (ESD) system to ensure a controlled shutdown of the transfer operation, in the case of a detected emergency. Designed according the IMO requirements (IGF) and complying to the ISO20519.

The iMSL® Small Scale solution is practical and has backward compatibility to the existing LNG and bunkering market. The iMSL® Small Scale has a 5 pin ‘SIGTTO type’ primary Electric link and a Pneumatic back-up link that are failsafe and independent as reasonable practical with independent connection points for Ship-to-Shore link.
