Two iMSL® systems: one control panel

Samsung Heavy Industries Co., Ltd. built two LNG Carriers for KOGAS to transport LNG from Tongyeong, Gyeongsangnam-do, to Jeju Island. One of the two LNG Carriers, SN2233, is also built with LNG bunkering capability. Due to the combined function of the vessel it operates in both the Large Scale and Small Scale LNG market. Both markets require different Ship-Shore Links to communicate the Emergency Shut Down Signal.

Different intelligent Multi Safety Link Systems (iMSL®)

The iMSL® Large Scale system Mampaey made for this vessel is outfitted with the following links: 6 pin Fibre-Optic, 37 pin Pyle and 6 pin Miyaki. The iMSL® Large Scale system is used for regasification projects and LNG cargo transfer.

The term Small Scale LNG (SSLNG) is used for the distribution of the LNG, focusing on volumes ranging from 1,500cbm up to 40,000 cbm. The Small Scale market has different safety requirements compared to the Large Scale market. For these operations the 5 pin SIGTTO and pneumatic link are required, which are included in the Mampaey iMSL® Small Scale.

Two iMSL® systems: one control panel

As explained, both the Small Scale and Large Scale market require different Ship-Shore Links to send the Emergency Shut Down Signal; Mampaey offers systems for both markets. Usually these systems are delivered in two separate cabinets, because in most cases only one system needs to be installed on a vessel. Only bunker vessels, such as the above-mentioned LNG Carrier SN2233, operate in both markets and therefore need both systems. To save space the two systems are combined in one cabinet and can be controlled with one and the same control panel.


In addition to this, the Mampaey iMSL® systems are backwards compatible. The systems are highly customizable and therefor able to be made fit for worldwide trading and different terminals, since rules and regulations differ not only per market, but also worldwide. Mampaey Offshore Industries can supply the requested links per area and market.
