Ch 2016   INNER APPROACHES TO MUMBAI

General information
Position
Mumbai Harbour (18° 54' N, 72° 49' E) is the premier port on the W coast of India; its fine harbour, about 14 miles long with 
a general width of about 5 miles lies E of Mumbai Island.

Function
The port of Mumbai has over 50 berths with modern equipment for handling general cargo vessels, container ships and tankers; 
it also has numerous anchor berths.
Mumbai is a major industrial centre; its population in 1987 was more than 8 million and rapidly increasing.

Topography 
Mumbai Harbour contains several islands, rocks and shoals; its coastline is heavily indented with small bays and inlets. The 
N and NW parts of the harbour are filled by a coastal bank upon which lies Butcher Big Reef (18º 58' N, 72º 53' E), the E and 
SE parts are also filled by another coastal bank upon which lie Karanja Reefs (18º 54' N, 72º 54' E). 
There are general depths of between 5 and 10 m over much of the central and S parts of the harbour, with lesser depths and 
large shallow or drying areas covering the E and N parts; a similar strip lies around the Colaba Peninsula in the W Depths in 
the berthing areas are subject to change by siltation and dredging.

Port limits
The limits of the Port of Mumbai are shown on the chart.

Approach and entry 
The port is approached from W and entered via a dredged channel, between Prongs Reef Lighthouse (18° 52'.7N, 72° 48'.OE) and 
an unnamed point of land 6 miles SE; the principal entry point being in the vicinity of a light-buoy (port hand) moored 1½ 
miles SE of the lighthouse.

Traffic
About 3000 vessels are handled annually.

Port authority
The port is administered by the Mumbai Port Trust, Port House, Shoorji Vallabhdas Marg, Ballard Estate, Mumbai 400 001,

Limiting conditions

Controlling depths 
There are maintained depths of 10.9 m in the channel from the E end of the approach channel, near the harbour entrance, to a 
position in the centre of the harbour, E of Middle Ground Islet (18° 55' N, 72° 51' E); thence there is a depth of 7.6 m in 
the channel leading WNW to the Port of Mumbai and 10.8 m in the channel leading NE to Butcher Island (Dia Deva) (jawahar Dweep)
(18°58'N, 72° 54' E).

Deepest and longest berths

A port radio service is operated. For details see the relevant  List of Radio Signals.

Notice of ETA
Vessels should send ETA, 96 hours in advance with confirmation 48 hours in advance to their agents, and 24 hours in advance 
to the Harbour Master. For details see the relevant List of Radio Signals.

Pilots and tugs 
Pilotage is compulsory for all vessels over 100 tons N of a line drawn E/W through Prongs Reef Lighthouse (18° 52'.7N, 
72° 48'.0E); such vessels may not enter, leave or shift berths in the area N of this line without a pilot or harbour official 
onboard. The pilot boards in the vicinity of a position 2 miles ESE of Prongs Reef Lighthouse. For further details see the 
relevant List of Radio Signals.

Tugs are available
Vessels carrying certain types of dangerous cargo are required by Mumbai Port Rules, a copy which is supplied by the boarding 
pilot, to make certain signals to Prongs Reef Lighthouse, these are answered by day with corresponding signals at the 
lighthouse.

Quarantine Mumbai should be advised 24 hours before arrival using the standard form of message from the International Code of Signals.  Vessels liable to quarantine follow the same procedure as that for vessels carrying dangerous cargoes.
Harbour

General layout
The principal alongside berths for general cargo vessels are situated on the W side of the harbour, with the Naval Dockyard 
located within the tidal basin close S of the cargo berths and Mazagaon Dockyard lying to the N of them.

Tankers are accommodated at Butcher Island or Pir Pau in the NE part of the harbour.

Anchor berths, for general cargo vessels, are located in the middle of the harbour on both sides of the channel; those for 
naval vessels lie in the W part of the harbour, S of the tidal basin.
There are several mooring buoys in the harbour, most are situated in or near shallow water.

Signal stations 
The Port Signal Station is situated in a conspicuous tower on the E side of the head of Ballard Pier (18° 55'.7N, 72° 50'.7E).
The Dock Signal Station stands on Bull's Nose at the entrance to Indira Dock, 4 cables N of the Port Signal Station, this 
station deals only with signals affecting the docking of vessels.

The Naval Signal Station is a conspicuous flagstaff which stands on the S point of the tidal basin, 6 cables SSW of the Port 
Signal Station. For details of the Naval Signal Station at Colaba Point .

Communication is by the International Code of Signals by day and by Morse code at night, or by VHF RT.  For details see the relevant List of Radio Signals.
Storm signals
Storm signals are displayed from the Port Signal Station (18° 55'.7N, 72° 50'.7E) and from a flagstaff at the NE corner of 
Victoria Dock, 1½ miles N; the general system is used.

Tidal streams 
Harbour. Tidal streams within the port of Mumbai set, with rates of ¾ to 3 kn, as follows.

East side of the harbour, in-going stream:
The stream sets NE abreast Karanja Island, setting more ENE after passing Karanja Beacon. Between Butcher Island and 
Elephanta Island the stream sets N, but towards Trombay Island it becomes NE.

West side of the harbour, in-going stream:
From Sunk Rock to Cross Island the stream sets NNE with a rate of 2 kn; N of Tucker Beacon (18° 56'.1N, 72° 52'.5E), where 
the stream separates, a branch of it turns N until abreast Mazagaon Dockyard; then the stream sets between NE and ENE to join 
the stream from the E side of the harbour N of Butcher Island.

East side of the harbour, out-going stream: The stream starts later here than on the W side of the harbour.
From the channel between Butcher Island and Elephanta Island, the stream sets SW, along the NW coast of Karanja Island; when 
abreast the entrance to Dharamtar Creek it sets WSW.
 
West side, of the harbour, out-going stream:
The stream at ordinary tides starts 30 to 35 minutes earlier than on the E side of the harbour; during strong spring tides 
the stream on the W side may start 40 minutes to I hour earlier. Inshore and near Indira Dock Wall, during the SW monsoon, 
the stream starts about 45 minutes before high water Mumbai.

From Trombay Island to Mazagaon Dockyard the stream sets SW.

From abreast Cross Island to W of Middle Ground Islet the stream sets SSW; in the middle of the harbour the set is S to SSW.
From Middle Ground Islet to Sunk Rock the set is between S and SSW, but with the start of this stream the set off Sunk Rock 
is more W-going.


Berthing area
The tidal stream in the vicinity of the tidal basin, Ballard Pier and the wet docks is as follows:
The in-going stream 'in the vicinity of the tidal basin and the wet docks is deflected by South Breakwater and runs parallel 
to it, joining the main in-going stream, which passes E of Middle Ground Islet. The stream then sets ENE past the entrance to 
the tidal basin. An eddy runs S along the E side of Ballard Pier, before turning W into the tidal basin; the effect of this 
eddy has been felt up to ½ cable E of the SE extremity of Ballard Pier.
The out-going stream flows close E of the head of South Breakwater, before turning SW parallel to it.

Anchorages and prohibited anchorages
General information

The harbour provides numerous anchorages and individual anchor berths for several types of vessels. The principal anchorage 
areas are shown on the chart, these, and uncharted anchorages are described below.

Merchant vessels anchorage 
The anchor berths for merchant vessels lie in the S part of the harbour, on both sides of the dredged channel; individual 
berths are shown on the chart.

An area of foul ground lies mid-way between C 1 and D I Berths.

As a general rule vessels should be moored SSW/NNE.  During the fine weather season vessels should moor with 80 m of cable 
on each anchor, and for the rest of the year with 110 m of cable on the S anchor and 80 m on the N anchor; a vessel moored in 
the eddies off Middle Ground Islet should have 140 m of cable on the S anchor.

Naval Anchorage

Caution.  A submarine cable is laid SW across the Naval Anchorage area from Middle Ground Islet.
An area is reserved for naval vessels between Sunk Rock and the tidal basin, 2 miles N,.
Mooring arrangements are similar to those for merchant vessels.
Quarantine anchorage

Vessels subject to quarantine will be instructed to anchor as convenient for boarding by the Port Health Officer.
Explosives anchorage

Vessels arriving with or embarking explosives or other dangerous cargoes will be anchored in the explosive anchorage located 
S of the main channel NNE of Karanja Beacon.

Tanker anchorages
Two anchorages for tankers are situated SW of Butcher Light-beacon (18° 56'.8N, 72° 54'.3E); a buoy (red, can) is moored 
between the anchorages and shoal water NW.

Emergency anchorage
An emergency anchorage is situated NE of Butcher Light-beacon.
Caution. A submarine cable is laid across the channel, between Butcher Island and Elephanta Island, close N of the Emergency 
Anchorage area.

Oyster Rock (18° 54'.1N, 72° 49'.7E). A prohibited anchorage area is established SW of the rock; its SE corner is marked by a 
buoy (white, can).

Middle Ground Islet (18° 55'.1N, 72° 50'.9E). A prohibited anchorage area lies close E of the islet.

Light-beacon to the S coast of Trombay Island.
The limits of the above prohibited anchorage areas are shown on the chart.

Basin and Berths
General information 
Cautions:

The maximum draughts quoted for alongside berths and depths at berths in the port are subject to change by siltation and 
dredging.  The Deputy Conservator of Mumbai Port promulgates declared draughts monthly.

Berthing area:
The tidal stream in the vicinity of the tidal basin, Ballard Pier and the wet docks is as follows:
The in-going stream 'in the vicinity of the tidal basin and the wet docks is deflected by South Breakwater and runs parallel 
to it, joining the main in-going stream, which passes E of Middle Ground Islet.  The stream then sets ENE past the entrance 
to the tidal basin.  An eddy runs S along the E side of Ballard Pier, before turning W into the tidal basin; the effect of 
this eddy has been felt up to ½ cable E of the SE extremity of Ballard Pier.  The out-going stream flows close E of the head 
of South Breakwater, before turning SW parallel to it.  See also information on the chart.  The alongside berths in the Port 
of Mumbai are situated in a series of jetties and wet docks on the W side of the harbour, the principal berths are described 
below.

Directions: 
The berthing areas are approached through a channel, with a maintained depth of 7.6 m and 2 cables wide, which leads NW from 
the main channel E of Middle Ground Islet towards Ballard Pier (18° 55'. 7N, 72° 50'. 7E).

Leading lights:	
Front light (framework tower surmounted by two discs, white with black borders, elevation 8 m) (18° 56'.ON, 72° 50'. 6E) 
stands near the root of Ballard Pier.

Rear light (steel mast with similar discs, elevation 12 m) (120 m NW of front light).  The alignment (305º) of these lights 
lead through the centre of the channel and S of Cross Island Reef (18° 56'. 5N, 72° 50'. 9E) which is marked at its S end by 
M Light-buoy (black and white, conical).

Naval Dockyard
Caution:	
The in-going and out-going streams flow strongly past the head of South Breakwater, causing vessels to sheer violently in 
this vicinity.  The Naval Dockyard lies within a tidal basin which is entered between the S end of Ballard Pier and the N end 
of South Breakwater, 2 cables S.

South Breakwater Light (metal mast on small building, 13 m in height) is exhibited from the head of South Breakwater.

Leading lights:
Front light (steel framework beacon surmounted by a white triangle with red stripe, elevation 
14 m) (18° 55'. 6N, 72° 50'. 2E) stands in the dockyard.  Rear light (similar construction, elevation 23 m) (183 m W of front 
light).  The alignment (about 265º) of these lights, which are exhibited occasionally, lead close S of Ballard Pier to the 
Naval Dockyard.

Ballard Pier
Ballard Pier (18° 55'. 7N, 72° 50'. 7E) is the main terminal for passenger vessels, it is connected to the main railway 
system. The N part of the pier is operated as a container terminal.  A light is exhibited from the head of the pier.  It was 
reported (1994) that vessels up to 228 m in length and 9.1 m draught can be accommodated.

Wet docks
There are three wet docks, described below, which provide a total of 52 berths.

Indira Dock:	
Indira Dock  (18° 56'. 4N, 72° 50'. 6E) is entered close N of Ballard Pier.  When a vessel is entering or leaving the dock by 
day a blue flag is hoisted at a flagstaff, near the dock entrance, on Bull's Nose; at night, the ship's name followed by the 
words "come on" are sent by light from the Port Signal Station.  Vessels up to 191 m in length and 9.1 m draught can enter 
Indira Dock  which is well equipped for working general cargo including containers.  Berths on the S part of the outside wall 
of Indira Dock are maintained by dredging to a depth of 7 m; there is an approach channel to these berths, dredged to 6.1 m 
close W of Cross Island Reef Vessels are berthed bows S on the outer wall, by swinging off Bull's Nose and being towed stern 
first to the berth; this operation is carried out during daylight hours only.

Victoria Dock and Prince Docks:
These areas is presently under reclamation.
Between the ferry terminal (18° 57'. 3N, 72° 51'. OE) and Mazagaon Dockyard, 7 cables N, there are several drying basins the 
positions of which may be seen from the chart.  A fish wharf stands close NNE of the ferry terminal.

Directions: 
A fairway marked by light-buoys, leads N from North Channel to a position off Mazagaon Dockyard.

Oil jetties
The principal oil jetties are situated in the NE part of the port.
Butcher Island Berths (18° 57'.5N, 72° 54'.5E) provide four berths for tankers in the NE part of the harbour. 
A concrete jetty with three berths, each flanked by dolphins, extends from the E side of Butcher Island; this jetty carries 
a roadway and pipeline and provides Nos 1 to 3 Berths, for tankers up to 225 m in length, 9.7 m draught and 70 000 dwt.
Number 4 Berth, for a tanker up to 300 m in length, 12.7 m draught, is situated on the edge of the dredged channel I mile 
SSW of Butcher Island to which it is joined by a causeway.

Berthing. Loaded tankers berth at high water, two tugs are required to be in attendance.
It is compulsory to test astern power during the approach to the port and again before berthing at the terminal.

A turning basin is situated 3 cables SSE of Butcher Light-beacon.

Tidal stream. The out-going stream sets onto Nos 1, 2 and 3 Berths; however, these berths are partially protected from the 
effects of the in-going stream, but it is reported that a set off the berths may be experienced.

Number 4 Berth lies almost parallel to the tidal stream, however, a set off the berth may be experienced.

Directions. The berths are approached via the channel described at 7.223, and thence, Nos 1 to 3 Berths, by the channel between Butcher Island and Elephanta Island.
Leading lights: Front light Uran Patch (18° 56'.1 N, 72° 54'.3E). Rear light Uran Beacon (5 cables SSW of front light).

The alignment (202¾º) of these lights lead to a position, E of Butcher Island Berths, in an area with a maintained depth of 
10.8 m.

Leading lights situated on the NE point of Butcher Island, in line bearing 255º, lead towards a small explosives pier and a 
mooring buoy, this mooring buoy was not on station in 1996.

Pir Pau Berths (19° 00'.0N, 72° 54'.5E), serving the refineries on Trombay Island, are an arrangement of named berths situated
on the S end of the island which project up to 4 cables SE of it; there is one long isolated finger pier, with a short T-head,
about 1 mile ENE of the main berthing area. The berths are used by vessels, up to 171 m in length, for discharging LPG, 
butane and petroleum in bulk.

New Pir Pau jetty (an extension of Pir Pau Jetty) lies, with its two deck T-head and flanked by berthing and mooring dolphins,
in Trombay Channel; there is a charted depth (1997) of 11.7 m alongside the berth. A turning basin, 450 m diameter with a 
maintained depth of 8.7 m, is located close SE of the berth; the berth is connected to a terminal, about 1½ miles NW, by a 
continuous jetty with a 5.15 m wide roadway.

The berth can accommodate one vessel at a time and is used for handling several POL products including LPG, LSHS, lube oil 
and bulk liquid chemicals; corrosive chemicals are not handled at this berth.

Vessels between 97 and 197 m length, with a maximum displacement of up to 47 000 tonnes and draught of between 10.6 m and 
11.1 m (depending on tidal conditions) may berth alongside. Berthing is available by day and night when weather conditions 
permit.

Directions. The channel for tankers berthing at Pir Pau continues from the channel described at 7.243; it leads N passing W 
of W Elephanta Buoy (black, conical) to a position W of Elephanta Patch Light-beacon (18° 58'.4N, 72° 55'.3E), then NE to the 
new berth described above. There is a maintained depth in this channel of 8.7 m, over a width of 180 to 200 m, from E of 
Butcher Island to the turning basin SE of the new berth.

From the turning basin vessels berthing at the other named berths proceed NE then N, following the buoyed deep water through 
Trombay Channel, to the E end of Pir Pau Deep about 1 mile E of the berths.

Pir Pau Deep, a buoyed channel with a maintained depth of 5.5 m, leads W then WSW to the products berths. There is a turning 
basin situated close off the berths at the W end of the Deep.

Pir Pau small craft channel. A channel, suitable for vessels with local knowledge, crosses the coastal bank in the NW part of 
the harbour from Mumbai Island to Pir Pau. The coastal bank is encumbered with several isolated wrecks, many shoal patches and submarine cables; the positions of which are shown on the chart.
Directions. From a position about 7 cables E of North Channel Beacon (18° 57'.1N, 72° 51'.2E) the channel leads NE to the Pir 
Pau Berths passing NW of Butcher Big Reef (18º 58'N, 72º 53'E). This poorly defined channel, is only marked by a buoy (black, 
conical) near its mid point and by another buoy (white, conical) about 1 mile NNE of Butcher Big Reef; however, the stranded 
wrecks and mooring buoys shown on the chart may provide additional guidance.
