| Brief Paragraph about your marine facilities | Dahej LNG Terminal of Petronet LNG Limited is situated in the southern reaches of the port area and presently has single LNG jetty designed to receive LNG Tankers of up to 2,20,000 m3 (QFlex) for the import of LNG. A second LNG jetty is being constructed 500 m immediate south of existing LNG Jetty for risk mitigation as well as designed to receive LNG Tankers of up to 2,65,000 m3 (QMax) capacity.
The existing LNG jetty consists of service platform on which is installed 3 LNG unloading arms and 1 vapour return arm for discharge of LNG cargo. The service platform is connected to the shore with a trestle of 2.4 km and provides vehicular access. To the North of the service platform there are 2 mooring dolphins and 1 double breasting dolphin. To the South there are 2 breasting and 3 mooring dolphins. QRMH are installed on each of the dolphins. A hydraulic operated gangway tower is located on the breasting dolphin south of the service platform. |

| Anchorage | An anchorage is designated for the use of LNG tankers that may have to anchor prior to or after berthing. Vessel should avoid anchoring. However, if it is extremely necessary to do so, LNG Tankers should anchor WEST of Petronet Jetty inside the following designated anchorage area:
Designated Anchorage Area:- Lat 21 43.30 N, Long 072 25.00 E
- Lat 21 43.30 N, Long 072 28 50 E
- Lat 21 35 00 N, Long 072 28 50 E
- Lat 21 35 00 N, Long 072 25.00 E
Prohibited Anchorage Area:Ships should not anchor in the area East of the line joining coordinates - Lat 21 35.00 N, Long 072 28.50 E
- Lat 21 43.30 N, Long 072 28.50 E
Masters are advised that strong tidal currents are prevalent in the Gulf of Khambat and great caution must be exercised while anchoring. A continuous and proper anchor watch must be kept at anchorage with Main Engines at short notice. Use of second anchor under foot and picking it up before every change of tide must be considered. |

| Draft (At the berthing structure, turning circle and channel) | Sufficient water exists at the jetty to allow a minimum under keel clearance at Chart Datum at ships draught of 12.7 meters. |
|---|
| Pilotage | Pilotage is compulsory for all vessels using the Dahej LNG Terminal. Pilot boards the Vessel about 2 hours before the HW / LW in position 2~3 nm SW of the jetty. Vessel speed is to be kept at less than 5 knots while picking up the Pilot. |

| Harbour Structure : Should include details about the number of jetties / berths, length & width of the jetties | Dahej LNG Terminal presently has single LNG jetty comprising of a service platform, 4 breasting dolphins & 5
mooring dolphins. The jetty is connected to the shore with a trestle of 2.4 km. The jetty can accommodate LNG
Tankers of LOA up to 320 m.
A second LNG Jetty of PLL is being constructed 500m immediate south of existing jetty and is expected to be commissioned in the first half of 2014. |

| Navigational aids | For outer approaches in Gulf of Khambhat, a Channel designated as Narmada Channel has been identified for use of LNG Tankers.
This channel is marked with 9 (1 fairway buoy + 8 channel buoys) buoys. The buoys are laid in accordance with IALA Standards.
Inner approaches to LNG jetty in general comprises of open waters and aid to navigation for these approaches is provided by LUHARA Lt. house and RACONS at Luhara Pt., Piram Island & Gopnath Point. |

| Mechanical facilities & Equipments | Dahej LNG Marine Terminal is equipped with state of art facility of International Standards for berthing / unberthing
of LNG Tanker and LNG unloading. Some of the important features of the facilities and its equipments
are:- TUGS : Four tugs with aggregate bollard pull capacity of 220 tons are available at the terminal for berthing / unberthing of LNG Tankers and to handle any emergency.
- FENDERS : LNG Jetty has 4 Super Cell Fenders one on each Breasting Dolphin. Each fender has rated strength of 375 tons.
- BERTH AID SYSTEM : Jetty is equipped Laser docking system capable of tracking berthing speed, distance and berthing angle of LNG Tanker being docked. These parameters are displayed digitally on two large display installed on mooring dolphins and are visible from a distance of 300 m from sea.
- Quick Release Mooring Hooks (QRMH) : QRMH are installed on each dolphin. BDs are equipped with double hook QRMH assembly and MDs are equipped with quadruple hook QRMH assembly. Each QRMH assembly has mooring capstan and each mooring hook has a Load pin incorporated into it for monitoring tension in ship’s mooring lines. QRMH can be released locally, manually & remotely.
- CT WINCHES : Four hydraulically operated Constant Tension mooring winches are installed on Mooring Dolphins for providing supplementary mooring lines from shore to the ships for additional safety.
- MLMS : The Terminal is equipped with Mooring Load Monitoring System (MLMS) and a CarryOnBoard laptop provided by Terminal to the visiting Tankers for their monitoring mooring line tensions.
- UNLOADING ARMS : The jetty is fitted with 3 LNG Unloading Arms and 1 NG Loading Arm with maximum allowed LNG unloading rate of 12000m3/hr. Each arm is installed with Quick Connect/Disconnect Coupling (QC/DC). Also each arm is equipped with Powered Emergency Release Coupler (PERC) for quick disconnection during emergency without draining the arms. The arm assembly is installed with Position Monitoring System (PMS) for monitoring the excessive movement (Surge/Sway/Drift) of ship and warning the operator. Also the PMS system is integrated with Emergency Shutdown System (ESD) which is automatically activated when the arms move beyond the permitted range.
- GANGWAY : Terminal has automatic gangway which has telescopic ladder and self leveling steps. Gangway has a "freewheel" mode which facilitates it to follow all the movements of the ship automatically.
