Vantage explosion proof connectors have been an integral part of the ESD (Emergency Shut Down) system since the mid-seventies.

In 1997 Vantage purchased the Pyle National Group which included the AF and GD series of explosionproof StarLine connector products. These ship to shore ESD and earthing connectors are engineered, manufactured, and third party tested-certified to the same exacting standards established by Pyle National.

Ship Shore Communication Link System

Electrical Communications and ESD Ship / Shore Link System

The Ship / Shore Link Control Panel, for Emergency Shut Down (ESD) & Communication System are used in LNG terminals as either a main system or a back-up system. The system handles: 4 telephone channels Shore / Ship ESD volt-free contact signals Additional shore - ship ESD signals as required by certain US import terminals The Electric Ship / Shore Link System is designed for Emergency Shut Down and Communications. Vantage AF Series 37 pin connectors are used in this system. To ensure safe functioning during emergency breakaway all ESD circuits are protected by intrinsically safe techniques. The telephone circuits, which must not pass thru barriers, are powered from shore and isolated by shore relays which are switched by continuity loops from the shipboard panel. The Vantage electric system can be supplied as a stand-alone, but can be installed in the same cabinet as the Fiber Optic Communications and ESD system.

The 37 pin / way AF Series connectors are North American 'Division' listed as “circuit breaking” explosion proof connectors to insure safe connection of the cable between the shipboard and jetty / shore receptacles. This interconnect system carries telecommunications, ESD digital and a 4-20 mA ship analogue process signal.

Vantage ESD receptacles are pre wired and factory sealed: external seal fittings / glands are not required. Connections inside the Vantage ESD receptacle enclosure are by crimp type splice.

AF Series connectors are CSA and C US listed for Class I, Division 1 Groups B, C & D and Class II, Division 1 Groups F & G. Vantage GD connectors are UL listed for Class I, Division 1 Groups C & D. Vantage AF and GD connectors are ATEX / CENELEC II 2 GD EEx d IIc T6 IP66/IP67 T70°C certified, KEMA 04 ATEX2179 X.

For added safety, Vantage AF and GD receptacles are pre-wired and factory sealed.

Stainless Steel Reel with protective cover

Safe stowage of the cable assembly is assured with a stainless steel (SS 316) reel with protective cover. The two-compartment drum design allows user to access both cable ends without need for removal of the complete length of cable. This design allows the terminal to first connect to the LNGC receptacle and then to the jetty receptacle.

Earth Ground Ship Shore System

Where earth/ground bonded connectors are required, they are also fitted with Vantage 4 pin GD Series receptacles, sometimes called sockets, whose pins are grounded to the ship’s structure.

Earth/ground receptacles are pre wired and factory sealed: external seal fittings / glands are not required. Connection to the plug is by screw type lugs.

GD Series connectors are CSA and C US listed for Class I, Division 1 Groups B, C & D and Class II, Division 1 Groups F & G; UL listed for Class I, Division 1 Groups C & D; and ATEX / CENELEC II 2 GD EEx d IIc T6 IP66/IP67 T70°C certified, KEMA 04 ATEX2179 X.

For added safety, Vantage receptacles are pre-wired and factory sealed.

Where ESD / AF and earth / GD receptacles are required they can be supplied as part of a single enclosure.

Circuit Verification Assembly

The Circuit Verification Assembly / CVA allows the LNG terminal and / or the LNG Carrier to check and verify required circuits. Carrying case is included.

Vantage Miyaki Adapter

To assist LNG terminals and LNG Carriers the following adapters can be supplied to easily transition between a Vantage 37 pin and Miyaki 6 pin ship-shore link used in selected Japanese, Korean, Indonesian and Malaysian terminals.

  • V-70649-VMA-2P-XXX – Vantage Miyaki Adapter (VMA) with 37 pin AF receptacle mounted to EEx d enclosure with two Miyaki (2P) plugs – each has 6 pins exiting the opposite side thru EEx d glands. Terminal blocks within the enclosure allow for necessary ship / terminal wiring changes. Carrying case is included.
  • V-70650-VMA-3P-XXX – Similar Vantage Miyaki Adapter (VMA), except with three Miyaki (3P) plugs.

Umbilical Cables

An ESD umbilical cable is supplied for ship / shore linking. The ground/earth umbilical would be similar in length to the pictured ESD cable.

An ESD umbilical cable is supplied for ship / shore linking. The ground/earth umbilical would be similar in length to above ESD cable. An additional feature specified by experienced LNGC operators to ensure safe functioning during emergency breakaway requires all ESD circuits to be protected by intrinsically safe techniques. The principal certification and protection is EEx d. NOTE: As added protection, Vantage AF and GD connectors are Class I, Division 1 Listed as “circuit breaking” plugs and receptacles.

Umbilical assemblies

It is a requirement of some terminals that the ship provided the ship / shore umbilical cable which is fitted at each end with Vantage Technology 37 pin Explosion proof Plugs. These plugs, if they follow the standard established by El Paso Marine in the mid 1970’s will have male (pins) inserts on both ends. If the ship has a earth/ground cable it will be fitted at each end with Vantage Technology 4 pin Explosionproof Plugs. These plugs follow the standard established by Shell / STASCo in the early 1990’s and will have male (pin) inserts on both ends. The cable used to interconnect the ESD is a heavy duty, flexible type with twisted, shielded pairs and a 600 volt non armored rubber jacket. Cable with an armor or armored and sheathed jacket is avoided to eliminate the possibility of inadvertent grounding. Both cables are fitted with Vantage mechanical clamp glands approved for hazardous area use to North American “Divisional” and CENELEC “Zonal” schemes. The cable end to be hauled onto the LNGC is fitted with strain relief basket weave grips.

Pneumatic Backup System /
ESD Ship-Shore Link System

The Pneumatic System is intended as a back up for the Ship / Shore Electric communications link and is incorporated into the Main Control system. The pneumatic ship / shore link consists of a shore system with pressure indicator transmitter together with solenoid valve for shore-ship trip function. The pneumatic components couple to a self-sealing connector located on the jetty. A hose connects the shore system to the ship system.

Umbilical Hose and Reel
An umbilical hose assembly allows for connection of the shore system to the ship side box. Safe stowage of the hose assembly is assured with a stainless steel (SS 316) reel with protective cover. The two-compartment drum design allows user to access both hose ends without need for removal of the complete length of hose. This design allows the terminal to first connect to the LNGC and then to the shore side control panel. The manually powered reel with sun cover is designed to accommodate 50 meters of hose . The actual length can vary to customer specification, typically 35-50 meters long. The umbilical hose is intended as a ship / shore assembly. It shall be fitted at each end with Nitta Moore non-sealing male connectors. The hose shall be a synthetic textile ply reinforced NR/SBR hose with an anti static abrasion resistant sheath. Bore is 3/8” and the hose is mounted onto the reel.

Fiber Optic Link System

The Fiber Optic Ship / Shore Link System (FO-SSL) is used in conjunction with the Electric ESD system. Both are compatible with Furukawa and SeaTechnik systems.

The fiber optic ship / shore communication link system communicates between LNG ship and LNG shore terminal through fiber optic cables. The fiber optic ship / shore link (FO SSL) consists of 4 channels of multiplexed communication data and emergency shutdown signals for a) ship to shore and b) shore to ship communication. These communication signals are divided into audio signals such as mooring tension monitor, telephone voice and interphone voice and dry contact signal for emergency shut down. A wide range of telephones may be used with the FO SSL, including a compatible Hot Line phone.
