Antan Terminal (NGANT)

The Antan production platforms are located several miles N of the terminal. The crude oil is transferred by pipelines to the Antan platform and then by hoses to the FPSO 'Nuim Antan'. From FPSO 'Nuim Antan' the oil is transferred to exporting tankers via a CALM Buoy. The tandem mooring method is only used if the CALM Buoy is non operational. If the CALM buoy is not in service the FPSO will moor bow to bow in tandem with export vessel with one or two mooring hawsers.

Tropical.

FPSO 'Nuim Antan' is located about 20nm, off the SE coast of Nigeria in the Bight of Biafra, S of the Calabar River.

Max for export tankers 150,000DWT (Tandem) or 350,000DWT (CALM). Min size 60,000DWT. No draught restrictions.

Designated anchorage area consists of a circle of a radius of 1.5nm, positioned 4nm S of FPSO 'Nuim Antan' mooring platform, in position 04°14'N 008°19'E. Depth 40m, holding ground soft clay.

Tankers should have the following mooring gear available and ready for use prior to arrival to the terminal: On the forecastle: 2 messenger lines with 5t shackles attached, 2 heaving lines, both windlass line store drums empty, crow bar and axe: On the poop deck: 2 heaving lines, 1 messenger line and bollard wire chain stoppers attached; At the port side manifold: 1 suitable messenger. Vessels using the terminal will be moored bow to CALM buoy by means of two 85m nylon mooring ropes connected to a 3in chafing chain on the outer end.

Pilotage is compulsory from a position 3nm S of the terminal, or at the anchorage, to the loading berth for all vessels and is performed by the Mooring Master who together with Custom Officials, meet ships in the previously arranged anchorage. A lee must be made for Mooring Master and officials to board (normally starboard side combination of pilot and accommodation ladders will be used) and have vessel to have ready 2 messenger lines forward, ship's derrick rigged on port side and port manifold fitted with 16in connection. The anchorage and pilot boarding area is situated 3nm S of the terminal. Pilotage is available for export tankers during day time until 1600hrs for berthing and throughout 24 hours for unberthing. All other vessels are required to call the terminal on VHF Ch 15 and request instructions.

Vessel is considered to be an arrived ship when it has arrived at the anchorage.

Radio beacon, 366.5kHz, "FPS", 0500-1700hrs daily. To comply with international regulations, during the hours of darkness the FPSO will show lights with the distinctive characteristics of Morse code letter "U". In periods of poor visibility the fog signal will sound the Morse code for letter "U".

Berthing operations will take place only during daylight time between 0600-1800hrs. Export tankers scheduled to berth on arrival should arrive at the pilot station no later than 1600hrs to allow time for inward clearance prior to commencement of mooring operations; if not, the vessel will be requested to anchor to await further instructions. Unmooring operations may be carried out at any time, day or night. Berthing is also subject to weather, sea conditions and visibility. During lay days the Notice of Readiness is acceptable only if tendered between 0600-1600hrs local time. Tandem mooring will normally not be attempted under any of the following conditions: ..... 1. One minute sustained wind speed 35kts 2. On hour sustained wind speed 30kts 3. Wind 20kts or more direction SW'ly (from direction of approach) 4. Wind induced sign wave height 1.2m 5. Wind induced sign wave period 4.0s 6. Significant swell height 3.0m 7. Swell peak period 14 sec 8. Swell direction 0-360° 9. Surface current 1.8kts 10. 7.0m depth current 1.2kts 11. Current direction NE'ly (setting towards FPSO) 12. Visibility 1nm CALM mooring will normally not be attempted under any of the following conditions: ..... 1. One minute sustained wind speed 35kts 2. On hour sustained wind speed 30kts 3. Wind induced sign wave height 1.2m 4. Wind induced sign wave period 4.0s 5. Significant swell height 3.0m 6. Swell peak period 14 sec 7. Swell direction 0-360° 8. Surface current 2.5kts 9. 7.0m depth current 2.0kts 10. Current direction NE'ly (setting towards FPSO) 11. Visibility 1nm Mooring Master has sole discretion on whether to proceed with mooring operation.

Range 2.0m. Currents: From Apr-Oct, mainly E'ly. From Nov-Mar (Harmattan), mainly W'ly. Within depths of 15.0-18.0m, current is irregular. Speed approx 0.5-1kt.

For tandem operation, there are normally 3 tugs (2 pullers and 1 pusher) available to assist in the mooring operation. Line boat and zodiac will be used to pass the hawser pick-up rope to the export tanker messenger line, and later pass the hose strings. The tug will be made fast, using the tug's line, at the bow of the export tanker. This tug, as directed by the Mooring Master, will maintain sufficient tension on the gear to prevent the tanker from riding up to the FPSO bow while berthing. After mooring has been completed, second tug will be made fast at the bow of export tanker. For the CALM Buoy operations, one 100t tug will assist with mooring, unmooring and during cargo operations. 2 hawser will be connected from the buoy, starboard first then port. During the period the lifting vessel is at the berth, a tug supplied by the terminal, will remain secured to the stern of the lifting vessel. The lifting vessel shall have no authority to direct or control the tug.

Prevailing winds: From May-Sep: SW'ly to W'ly 25-30kts. From Oct-Apr: Variable winds of unpredictable force. From Dec-Feb: Mainly N'ly 5-10kts. Squalls: From Mar-Nov: Unpredictable in force and direction but winds of 55-60kts have been recorded. Masters are advised to keep a sharp look-out for these unexpected changes in weather conditions, keeping engines ready at all times to be able to leave the berth under full power at short notice. Rain: Wet season runs from Jun-Oct. Average yearly rainfall is approx 370cms. Squalls are usually accompanied by torrential rain, thunder and lightning. Swell: Throughout the year a long low SW'ly swell prevails. During the wet season this swell together with rough seas becomes very high, particularly during heavy squalls. Fog: Virtually non existent. Temperature: Average temperatures range between 28-30°C.

All vessels must fly the Nigerian national ensign at their foremast or other appropriate place when in the vicinity of the terminal. During loading, International Code flag "B" should be displayed from a topmast signal halyard by day or a red light, visible at least 1nm, at night.

Vessels loading at the terminal must comply with the latest SOLAS and MARPOL Conventions and Protocols and relevant OCIMF recommendations. Vessels, which are found to be seriously deficient in any way, will be refused to berth or load. Masters of vessels calling at the terminal are advised that under no circumstances are engine repairs, or immobilisation of the main engines, steering gear, deck machinery power source, or any other essential equipment permitted within the terminal limits.The following is a summary of most of the essential requirements which must be met by tankers lifting oil at Antan Terminal: ..... 1. Berthing and unberthing shall only be permitted at the discretion of Mooring Master. 2. No dirty ballast disposal. 3. Advise arrival time by radio. 4. Mooring Master, together with Custom Officials, meet ships in suggested anchorage area. 5. Have ready: two messenger lines forward, ship's derrick on port side, port manifold with 16in connection. 6. Vessel's Master is responsible for the safety of his own ship at all times. 7. Lifting vessel's crew perform all operations of mooring, connecting and disconnecting hoses and unmooring aboard lifting vessel. 8. Do not close valves against crude flow. 9.
