Answer 8

Bar Pilot service area starts from Southwest pass and ends at Pilottown

Question 9

Crescent Pilots

Answer 9

Crescent River Port Pilot service covers the area from Pilottown to VG LNG berths.

Question 10

Staging/Mooring of Tanker

Answer 10

The Marine Coordinator on duty will spot the LNG Tanker * Spotting will be the vapor arm on all berths
* Spotting on the LNG tanker will be the vapor manifold

Question 11

Tanker All Fast

Answer 11

Once All Fast, the Master shall ensure and confirm with the PIC that the LNG Tanker has completed the following steps:
* On steamships, the main steam valve is locked shut
* On motor ships, the main engine is isolated
* On Dual Fuel Diesel Electric (DFDE) ship’s propulsion motors are isolated

Question 12

Staging Gangway/SSL Connection

Answer 12

VG will connect the ship-shore link immediately after the gangway is on board fiber optic ship-shore link (FOSSL) or an electrical ESD cable.

Question 13

Pre Tansfer Meeting

Answer 13

Question 14

Arm Connection,Leak Test/ purge

Answer 14

The vapor return arm will be connected first, followed by the liquid arms.
* The LNG loading arms will be purged with N2, supplied by the LNG terminal, until the O2 level is below 1% by v ol ume
* Once the O2 level is below 1% by volume, the LNG loading arms will be pressurized with N2 to a pressure of 5 bar in each liquid arm and 2 bar in the vapor arm

Question 15

Warm ESD Testing

Answer 15

The ESD testing will be as followed: * 1st ESD Test- Shore to Ship
* 2nd ESD Test- Ship to Shore

Question 16

Open Custody

Answer 16

The following must occur before Opening Custody is allowed:
* All arms are connected
* Vapor arm is closed to shore ( if applicable)
* Stopped gas burning in the GCU
* Cargo Surveyor is present

Question 17

Loading Arm Cooldown

Answer 17

VG and the LNG Tanker shall coordinate to control the liquid arms’ cool-down rate not to exceed 5°C per minute as per the manufacturer’s specifications

Question 18

Tank Gas Up

Answer 18

Send slip stream of LNG from one loading arm to Tanker’s vaporizer then into the Tanker’s tanks. The inert gas displaced will be sent to the marine flare until VG determines it can be sent to the BOG system. Gas up complete when the hydrocarbon content >95% by volume at the top of the filling pipe and 99% at the tank bottom and CO2 is less than 1% by
volume .
