The document provides details on the proposed aids to navigation for the TransLNG FSRU terminal located offshore of West Java Province, Indonesia. It describes the terminal location and key features. Five types of aids are proposed, including a jetty beacon, four special mark buoys to mark the terminal boundaries, and an isolated danger mark buoy. Specifications for each aid such as colors, shapes, lights and coordinates are provided to ensure safe navigation around the terminal area.

GENERAL SPECIFICATION
AIDS TO NAVIGATION
TRANSLNG FSRU TERMINAL
1. TERMINAL DESCRIPTION
The TransLNG FSRU terminal is located in West Java Province of Indonesia, at the north-west
side of the river mouth of CBL Bekasi and about 7 km away offshore of north Java Sea. It is
located within inner port of the Nwe Greater Jaarta Port or about 7 miles away north-east side og
the exsisting Tanjung Priok Port of Jakarta. The TransLNG channel and the LNG berth is located
at natural water depth of about -54.1 ft (-16.5 m) LAT. The terminal berth where the TransLNG
Floating Storage and Regassification Unit (FSRU) Facility laid up berthed at all time, was
designed to facilitate an STS (double bank) operation of the cargo transfer between the coming
LNG vessels and the FSRU facility. Where the FSRU facility is safely moored against the terminal
mooring dolphins and the coming LNGC vessels with the FSRU faciluty. The arriving LNGC vessels
proceed up the channel to the turning basin adjoining intracoastal waterway and maneuver, with
the assistance of tugs, astern toward the STS berth (FSRU). All berthing is port alongside the
terminal as well as the FSRU facility. This maneuver is based on extensive full mission bridge
simulations which have proved it viable and safe.
The berth is customary design to accomodate the safe berthing of the FSRU faciluty with cargo
caqpacity of 150,900 m3 plus the coming LNGC vessels of between 88,000 m3 and 267,000
m3 cargo capacity.

4. Proposed locations of Aids to Navigation
Proposed locations for the placement of Aids to Navigation are shown in figure-3 below.
Figure-3: Proposed locations of Aids to Navigations
The following types of aids to navigation are proposed:
- Jetty beacon to be located on top of the jetty;
- Special mark buoys to be located at the four (4) corners of concession area boundary;
- Isolated danger mark buoy to be located at the location of Levina Ship Wreck.

JETTY BEACON
The pole type light beacon should be suited for wharves, piers, jetties and quays, and oil/gas
berths. The jetty beacon should be designed to be of a simple robust structure, easily
transported and installed as aids to navigation.
Batery enclosures should be incorporated to house primary batteries or rechargable storage
batteries and charging controller for solar power system or AC/DC converter for recharging the
storage batteries.
Typical dimensions of jetty beacon is shown in figure-5.
Dimension (height) and fixing on the jetty shall be advice by the supplier considering the local
conditions.

SPECIAL MARK BUOYS
Special marks are not primarily intended to assist navigation but are used to indicate a special
area or feature whose nature may be apparent from reference to a chart or other nautical
document. Special marks are yellow. They may carry a yellow “X” topmark, and any light used is
also yellow.
In the case of TransLNG FSRU terminal considering the nature of its location, the special mark
buoys should be swift current type buoys that are designed for service in locations subject to
swift currents exceeding 4 knots and provides excellent stability characteristics with low
resistance to current flow for reduced drag effect.
Topmark Singe yellow “X” shape
Colour Yellow
Shape (buoys) Optional, but not conflicting with navigational marks
Light (when fitted)
Yellow White
Rhythm - Group-occulting light; or
- Single-flashing light, but not a long-flashing light with a period of 10
seconds; or

“U”
Typical dimensions of maritime buoy is shown in figure-6.
Dimension and fixing/anchoring shall be advised and designed by supplier considering the local
conditions.

ISOLATED DANGER MARK BUOY
The isolated danger mark is placed on a danger of small area that has navigable water all around
it. Distinctive double black spherical topmarks and group flashing (2) white lights, serve to
associate Isolated Danger marks with cardinal marks.
An isolate danger mark is a mark erected on, or moored on or above, an isolated danger that has
navigable water all around it.
Topmark 2 black spheres, one above the other
Colour Black with one or more broad horizontal red bands
Shape (buoys) Optional, but not conflicting with lateral marks; pilar or spar preferred
Light (when fitted)
Colour White
Rhythm Group flashing light with a group of two flashes, in a period of 5 or 10
seconds
