Emergency Shutdown (ESD) System for LNG carriers takes important role to protect the ships from damages caused from fire or explosion, and other causes. Guidelines from SIGTTO states the role of ESD system as,
- Cargo tank overflow control
- Cargo tank pressure protection
- Gas burning safety system
IMO Resolution MSC.370(93), called as New IGC Code (International Code for the Construction and Equipment of Ships Carrying Liquefied Gases in Bulk), is the internationally accepted requirements including ESD systems for LNG carriers. The new IGC code adopted on 22 May 2014 applies to New Builds whose keel laying is on or after 1 July 2016 as well as existing ships constructed on or after 1 July 1986 and before 1 July 2016, §1.1.1 MSC.370(93). Also, suggests that Authorities should ensure that the requirements in the new IGC codes are complied with, §126.96.36.199 MSC.370(93).
Implications to the ESD system on LNG carriers, §13.8.10 MSC.370(93), is that the system development and maintenance should be in accordance with the requirements in
- Development: International Electrotechnical Commission standard ISO/IEC 15288:2008 Systems and software engineering – System life cycle processes
- Maintenenace: ISO 17894:2005 Ships and marine technology – Computer applications – General principles for the development and use of programmable electronic systems in marine applications.
There are technical changes in the system configuration for new ships and existing LNG carriers to be made from ESD system point of view. More importantly, product life cycle management system for ESD system should be made and integrated with ship’s management system.
STI, as the main supplier of ESD systems for LNG carriers and their derivatives like LNG FPSO, LNG FSRU, and LNG RV, offers the ESD system upgrades and life cycle management system to integrate with ship’s management system.
For any inquiries about upgrading existing ESD system for LNG/LPG carriers and their derivatives, please contact STI.
