Trip Report Visit to Gambia

Project: Technical Assessment Visit Date: 31st August 2017 Location: Gambia Ports Authority | Banjul Objectives: To do a Technical assessment on their Port to identify the gaps in the ATON and VTS. Attendance: Capt Kulay Manneh (Harbour Master) Mr Yahya Badjie (Lighthouse Navigational Services) Mr Ansu Gibba (Administrator to the Director General) Mr ABDoulie m Tambedou (Director General)

Buoys

Concerns of Port

• 1. Fisherman moor onto them using the lifting eyes, the radar reflectors and safety/climbing rails
• 2. They drag them off position
• 3. Mooring causes damages to buoys
• 4. No AIS monitoring
• 5. Radar reflectors are mounted right on top of the buoys.
• 6. Colour faded after two years of service

Recommendation MDSol to contact supplier and provide solution / feedback to GPA. The Buoys that you see in the pictures was launched in March 2015 and has been damaged by fishermen and is faded.

1Fairway Buoy

Buoy Lights

• 1. Not fitted with GPS to synchronize the flashes
• 2. Lights need to be removed to re-program or do status checks

Recommendation

• 1. Use lights with GPS and AIS functionality.
• 2. AIS will send messages and warnings to the VTS system when buoys are dragged or moved from

position.

• 3. New lights have Bluetooth technology for remote programming and maintenance
• a. Enhances staff safety – no need to climb onto buoy
• b. More effective maintenance and scheduling of component replacements before failure

Lighthouse Lights

• 1. No buildings but towers are used
• 2. Lights used are flashing and not rotating and are sealed outdoor units
• 3. Pharos supplied units
• 4. They have 3 of these units mounted on towers
• Banjul Tower – 12nm (WHITE)
• Fajara Lighthouse – 15nm (WHITE)
• Barra Tower Light – 10nm (RED)
• 5. Daylight sensor went faulty and they had to replace complete light. (No Spares)
• 6. Light houses(towers) are solar powered

Recommendations: MDSol will approach Sealite for a new light source. Leading markers (No Lights)

• 1. Physical markers are used and not lights
• 2. Port requires lights
• 3. Light information and specs to be provided by GPA

VTS system

Concerns of the Port

• 1. Fishermen drag buoys off position. No VTS monitoring of Buoys
• 2. No AIS and Radar currently installed at the Port.

Current Installed Systems

• VHF Radio
• Navtex
• SSB and MRSAT C- Installation is

incomplete Benefits of AIS and RADAR to the customer

• Will have Radar visibility of buoys to

ensure they do not drift off position.

• Buoys that sunk will be detected by the
• perator on duty on the VTS display

(Radar).

• Buoys with AIS capability will be displayed on the VTS system for the operator to monitor.
• Activity of fishing vessels around the buoys can be monitored and limited by the VTS operator.
• Added security and reduction in maintenance cost to the port assets and equipment.
• Promote safety
• Improves efficiency of Vessel Traffic

within the port.

• Protect the environment
• Improves Coordination of Search and

Rescue

• Assessment of risk

Requirement Radar coverage requirement

• +-7 NM From the port tower up and

down the channel

• +- 12 NM from Fajara site

2 Port Control 3 Port Control

Port Control Centre

• 1 VTS Display System
• AIS (installed in Control centre to reduce cable

run)

• AIS antennas (to be mounted on Port Control

roof) Server Room (Control Centre)

• Server room is on ground floor and has UPS,

Aircon, sufficient space for another cabinet and cable access to the control centre.

• VHF Reciters (required)
• VTS Recorder (required)

Port Control Radar Tower (First RADAR Site)

• Radar to be mounted on the Tower in front
• f the current port control building
• This tower needs to be replaced with a

higher unit to accommodate the car carriers entering the port (45m high – as per captain Manneh)

• Tower Height recommended is 60meters
• Connectivity between the Tower and Port

Control to be established

• Kiosk at Tower with aircon and UPS (for

CSET depending on Radar used)

• Current Port authority building has a

standby generator to overcome electricity issues in the Town. Fajara Lighthouse Tower (Second RADAR Site)

Figure 4 Server Room

• 5. Radar Tower (First Site)

• 6. Radar Tower (Second Site)
• This site is +- 15 meters above sea level and the Tower is an additional 15 Meters
• A new tower structure is recommended to accommodate the Radar installation and a height of

at least 60 meters above sea level is required. (12nm Coverage Required)

• Microwave link from this site to the new structure in the port. (depending on line of site)
• Line of site to be confirmed by Yanya Badjie – Lighthouse technician
• This site currently has 1 solar panel for the light only.
• Electricity is not stable at this site. Can be off for 4 -5 hours in a day.
• Recommend a Kiosk at Tower with aircon and UPS (for CSET depending on Radar used)
• Generator also required at this site due to Power outages

Customer System Delivery Plan (Phased Approach)

• 1. VTS with AIS monitoring capability
• 2. Optional on 1st approach, AIS and VHF recording (including VTS Recorder, and four VHF Receiver

Units).

• 3. Port Control Radar
• 4. Fajara Radar
• 5. SLA for maintenance separate
