Mizushima Chiku lies in the left bank of Takahashi Kawa and works as an industrial port. It

is one of the leading petrochemical industry zones. Within the harbour there is Inner Harbour Passage.

It is a rapidly developed industrial port following the construction of heavy industrial zone at the reclaimed yard in thefront.

Cautions.
1. At Mizushima Traffic Route connecting with the S entrance of Inner Harbour Passage, Vessels of 50m or more in
10

length are regulated the duty of sailing the traffic route by Maritime Traffic Safety Law.
2. Large vessels must keep clear of the shoals with a depth of some 10m which extends near the buoy with a white light(34°26.6′N 133°46.3′E). A number of fishing boats may congregate in this area.
3. Inner Harbour Passage and the fairway are dredged down; therefore they suddenly get shallow while running off
from the passage or the fairway.

15

4. Since there are many vessels sailing near Mizushima Ko, there are many casualties like collisions. Especially caution
must be paid to the area near the S entrance of Inner Harbour Passage since many coastal vessels sailing Shimotsui
Seto come in and out Mizushima Ko or cross Mizushima Traffic Route.

227

白色の文字列Inner Harbour Passage regulated by Port Regulations Law is connected with the N entrance ofMizushima Traffic Route regulated by Maritime Traffic Safety Law. The passage is about 2.5M in length, 450~700m in
width and about 16~22m in depth indicated by many light buoys. At the passage, traffic controls designated by the Port
Regulations Law are operated. (See “Traffic Control Signal” on page 227.)

Fairway.
1. There is a fairway with the depth of 10m or more towards Seto Futo Pier (34°28.1′N 133°46.0′E) in the N from theE side of the S entrance of Inner Harbour Passage and indicated by light buoys.
2. Another fairway reaching the estuary of Takahashi Kawa from the N side of Noji Shoto via the S side of JFE Steel(West Japan Works) is the depth of 10m or more and indicated by several light buoys.

Traffic Control Signals.

Vessels proceeding in Inner Harbour Passage prescribed by the Enforcement Regulationsin Specified Port shall comply with the traffic control signals made by the Captain of the Port at the Signal Station.
For vessels of 70m or more in length (prohibition signal and prohibition notice signal are to all the vessels) using Inner
Harbor Passage, the following Control signals are displayed at Mizushima Signal Station are listed in the following table.
(See “Landmarks” on page 226.) to control the traffic in Inner Harbor Passage.
15

Furthermore, a new inner harbor traffic control using AIS was introduced in June, 2012. An uncontrolled vessel subject
to control (with a length of 70m or more and less than 200m), which receives permission under certain conditions andinstructions from the Captain of the Port, is allowed to meet up with a controlled vessel (200m or more in length) in Inner
Harbour Passage and depart from the Inner Harbour Passage before the controlled vessel enters the Mizushima Traffic
Route. Make a request to the Captain of the Port (via the Bisan Seto Vessel Traffic Service Center) if a vessel subject to20

control requires navigation by this new inner harbor traffic control. (See “Traffic Control using AIS” on page 228.)[Replaced by new table]

Port Traffic Control using AIS.
1. Traffic control for a controlled vessel and an uncontrolled vessel in the passage.
(Traffic control according to vessel length)5Previously when a controlled vessel (200m or more in length) navigated on Inner Harbour Passage, passage of all
uncontrolled vessels (with a length of 70m or more and less than 200m) was restricted.
With this traffic control, because AIS information is used, under certain conditions an uncontrolled vessel which has
been recognized by and received instructions from the Captain of the Port may enter Inner Harbour Passage when thesignal “O” is flashing “O” (priority for departure), or may depart via Inner Harbour Passage when the signal “I” is10

flashing “I” (priority for entering).
2. Control for departure of uncontrolled vessels before a controlled vessel enters the Mizushima Traffic Route.
(Outbound control when the inbound signal “I” is flashing “I” (priority for entering))
Previously when a controlled vessel (200m or more in length) passed through the Bisan Seto E Traffic Route or the
Bisan Seto S Traffic Route to navigate for the N on the Mizushima Traffic Route (when the inbound signal “I” is15

flashing “I” (priority for entering)), departure on Inner Harbour Passage was restricted for all uncontrolled vessels(with a length of 70m or more and less than 200m).
