An entrance channel connects the port with the deep water of the Sutherland Channel. The port was originally dredged to -12 Metres but now it has been further dredged to a depth of – 13 m. The dredged depth of - 13 meter CD allows for arrival and departure of LNG carriers up to a draft of 12.3 m. The straight approach channel has a clear width of 700 m at the seaside tapering off to a width of 470 meter between the breakwaters to allow unobstructed easy entrance/departure of ships. The orientation of the approach channel is heading 070 - 250 degrees north.
Port approaches through Magdalla Port waters
The LNG carrier approaches the Hazira (Surat) Port through the Magdalla port waters. Ships bound for Hazira will have to report to VTMS (Khambhat East) on channel 09, two miles south of the Magdalla Port Limits. The Hazira (Surat) Port pilot will board the ship just outside the Magdalla Port waters. The whole route from pilot station to Hazira Port dredged approach channel is 7 NM long. Strong tidal currents are present in the channel in North and South directions. There are no crosscurrents. The Malacca banks act as a natural breakwater for waves and swells during low water but at high water waves and swell pass unrestricted over these banks. During strong SW monsoon conditions and at high water the waves in the Hazira approach can be as high as 2 meters coming from a 250 degree- direction.
LNG CARRIERS PASSING THROUGH THE MAGDALLA (SURAT) PORT.
During the transit of the LNG Carrier from the open sea to the Hazira LNG terminal the LNG Carrier is exposed to the same operational risks as any other ship of similar size, however the consequences of severe structural damage to the LNG Carrier will be far more serious than those of similar incidents involving other types of ships and in order to reduce the risk of an incident involving the LNG carrier passing through the Magdalla (Surat) Port the following has been adopted from 11th April 2005.
The General Lighterage Area is shifted 0.5 NM East to give more clearance to vessels passing North of General Lighterage Area as a special precautionary measures and new co-ordinates are: 21.02.0 N, 072.34.5 E, 20.59.0 N,072.34.5 E, 20.59.0 N, 072.36.5 E, 21.02.0 N, 072.36.5 E
All ships engaged in lighterage operations are instructed to only anchor in this area.
The one-mile wide corridor between the General Lighterage Area and the Malacca Banks will be used for the safe passage of the LNG Carrier to the Hazira (Surat) Port as well as for tankers proceeding to and from the Reliance SPM. The passage is also used by all vessels bound from / to AHPPL.Only one vessel is allowed in this corridor at one time. Magdalla Port Control through VTMS(Khambhat East),should be informed by Shell LNG Tankers and Reliance”s Tankers, and latest traffic position should be taken before proceeding to North of General Lighterage Anchorage.
The LNG Carriers/Tankers will inform the Magdalla Port Control of its expected arrival time at the corridor and request passage approval.
All vessels following LNG tankers shall keep behind, such LNG Tankers at a safe distance of not less than 1 NM. Similarly, LNG tankers following another vessels ahead of her shall keep a safe distance of at least 1 NM, behind such vessel.
A Port tug will escort the LNG Carrier when passing the General Lighterage Area advising other traffic to keep clear or to assist the LNG carrier to turn in case of an emergency.
The tanker anchorage area has been shortened by one nautical mile to allow for safe, unobstructed tugboat fastening and channel alignment of the LNG carrier. New anchorage coordinates are: (A) 21* 06.0’ N 072* 35 0’ E (B) 21* 06.0’ N 072* 33.5’ E (C) 21* 05.0’ N 072* 33.5’ E (D) 21* 05.0’ N 072* 35.0’ E
In case the LNG Carrier will have to wait or anchor it will do so outside the Magdalla Port Limits.
Only in case of an emergency will the LNG Carrier anchor in the Magdalla Port Waters at a safe location as indicated by the Magdalla Port / VTMS(Khambat East). All traffic will be instructed to give the LNG Carrier at anchor a wide berth. Due to its large size above and under water the LNG Carrier is more likely to drag anchor in strong SW monsoon winds and in the strong currents in the Sutherland Channel.
The Hazira (Surat) Port pilot will board the LNG carrier well south of General Lighterage Area as a precautionary measures to pass vessels at anchor in the General Lighterage Area with pilot on board.
The port contains a turning basin with a radius of 300 meter for the manoeuvring of Tug assisted LNGCarrier during berthing and un-berthing. The depth of the basin and the LNG-Carrier berth is such that the LNG-Carrier is able to leave the berth at all times.
The breakwaters provide protection for the berth from the SW monsoon waves and swells and for the currents parallel to the coastline. The causeway provides access to the LNG jetty and is at such a level that flooding under design still water conditions is prevented.
The recommended anchorage is in a location approximately 11 miles SW of the harbor, outside the Magdalla Port Limits, where the sea bottom is sand and is of good holding ground. Anchoring is prohibited within Port Limits, unless the anchor is used temporarily to support vessel maneuvering or in case of an emergency.
The Hazira (Surat) Port waters are only two miles wide ,with a dredged approach channel of 1200 meters long. The tugs will be made fast before the ship enters this dredged channel. The port was originally dredged to -12 metres but now it has been further dredged to a depth of – 13 m. CD and is marked by two navigational buoys at the seaward end, two navigational markers on each breakwater end and leading lights, 070-250 degrees. Inside the harbour there is a turning circle with a 300 m radius, also dredged to –13 m CD. The berth pocket has been dredged to – 13m CD. Maneuvering the ships in and out of the port has been extensively tested on simulator. Port entry will be done with a minimum of three tugs attached. There can be strong, tidal, cross currents in the dredged channel. The pilots will be assisted with a PPU, Personal Pilot Unit. Pilot boarding location: Latitude: 20 deg 54’ North, Longitude: 072 deg 35’ East.
