Marine LNG complete equipment

5.1 Marine LNG complete equipment

Summary

Marine LNG gas station is the service place that built in inland rivers or coastal zone to refuel fro LNG ship. It can be divided into 3 types as per different water area and shoreline environmental conditions, different model of station building:

1. The LNG filling station that built depends on wharf collectively called coastal base station, e.g. trestle bend wharf fixed station, bulkhead wharf fixed station.
2.The LNG filling station that built depends on pontoon collectively called pontoon station, e.g. pontoon wharf or pipe gallery type, independent pontoon type.
3.Mobile filling station is built depends on power driving vessel, which has the characteristic of mobile filling service.

5.1.1 Shore-based Type LNG station

Summary

Shore-based type LNG station consists of LNG cryogenic storage tank, cryogenic immersed pump skid, marine LNG dispenser, instrument wind system, PLC control system. Functions: unload, unload a ship, LNG filling for ships, metering etc. Modular design, high integration level, convenient and swift to install.
Key Parameter

5.1.2 Pontoon type LNG Station

Summary

Pontoon type LNG station consists of cryogenic storage tank, storage tank ice chest (include cryogenic immersed pump), filling arm (filling hose), instrument wind system, security system. Functions: unload, unload a ship, LNG filling for ships, metering etc. Modular design, high integration level, convenient and swift to install.
Key Parameter

5.2  Complete equipment for LNG fuel-driven vessel

5.2.1 LNG supply Equipment for Fuel Power-driven Vessel

Summary

LNG supply equipment consists of storage tank, storage tank ice chest, fuel gas doublewall pipe, ventilation system, instrument wind system. Function: filling and supply of storage tank, pressure regulating of storage tank, gas supply for engine, safety relief, mechanical ventilation etc. Safely and stably supply gas to natural gas engine and dynamo.

Key Parameter

5.2.2 LNG Fuel Power-driven Vessel Security System

Summary

The security system consists of engine room security control cabinet, driving console remote alarm board, filling LBZ. The safety system and control & monitoring system is mutual independence, safety system prior to control & monitoring system, system is of high security.
The power supply of this system uses redundant design, main power supply and standby power supply are redundancy, the other power supply can supply power without closing down while one breaks down. The system equipped with UPS module and backup battery, and the backup battery can continuously supply power for 30 minutes.
This system uses distributed design concept, the left and right control unit are respectively controlled by 2 sets independent control unit, and the security signal accesses to the safety system independent of control system. The controller of safety system uses the PLC controller with safety certificate, the complete system reaches SIL Ⅱ safety level.

Each  control  unit  with  I/O  module,  it will  not  affect  other  control  unit  even  if  one  breaks  down, which  minimizes  risks. 
Each control unit equips with touch display screen, there is remote alarm display in the cab console, audio-visual display and easy operation.
The system equips with wireless data remote transmission interface, which can upload equipment operational condition, ship location to  shipowner  information  management  platform,  then  the  shipowner  can  view  equipment  operational  condition,  fuel consumption condition and ship navigation track etc, in real-time.

5.3 Ships Information Management Platform

Summary

With the increase of LNG vessels, the management platform with function of safety supervision and filling facility dispatching management  is  demanded.  Therefore,  our  company  develops  the  information  management  platform  that  applies  to  security supervision of gas storage, gas supply, gas use for LNG ships, ship location, filling facility intelligent dispatching management. It is available for security supervision and operation dispatching  management of ships of  marine  bureau,  shipowner and gas filling operating enterprise.
