Okoro Terminal (NGOKN)

The terminal, located in OML 112, in shallow water, comprises the FPSO 'Princess Aweni'. The FPSO is a converted 71,760 DWT Tanker with crude oil processing facilities, storage facilities and offloading facilities including a fiscal metering system and floating hose to enable crude oil to be transferred to the tandem moored Offtake Vessel.

FPSO 'Princess Aweni' is located in the Okoro Field offshore Nigeria.

Draught 8.75m, 75,000DWT.

Anchoring within 2km of the exclusion zone surrounding the Facility is prohibited. On the day, the Offtake Vessel should proceed to the Daylight Anchorage/ Pilot Boarding Ground approx 3nm SE of the Terminal (Lat 04° 22.5' N Long 007° 52.0' E), or the alternative anchorage area which also the alternative pilot boarding ground which is approx 1.5nm ENE of the Terminal ( Lat 04° 25.5 N Long 007° 50.6 E ). The Offtake Vessel may anchor at this location whilst waiting for the Terminal Pilot and waiting for port clearances and should anchor without the assistance of the Terminal Pilot. Offtake Vessels are advised not to anchor at these locations overnight unless authorized by the Terminal via email and VHF and not to proceed to or from the daylight anchorage position during the hours of darkness. If night anchorage is not authorized by the Terminal and for longer term waiting, Offtake Vessels should stay well clear of the Terminal. The Ima Oil Terminal anchorage (Lat: 04 09.5 Long: 007 23.6’E) can generally be used if desired by the Loading Vessel. The seabed at Okoro can be characterised as very soft clay to very soft, slightly sandy, clay with occasional shell fragments.

When within VHF communication range, Masters of Offtake Vessel should ascertain berthing instructions from the Facility on VHF channel 13.

BA 1386 and 1387

The mooring system generally has the following “pull in” lines : 200m x 20 to 24mm messenger line 110m x 72 to 80mm polyprop mooring line These are brought into the Loading Vessel’s empty mooring winch drum. The mooring consists of: 6 m x 76 mm chafe chain - which is secured in the chain stopper. 60 to 90 m OCIMF mooring hawser with floatation collars connected to 7 m x 76 mm chafe chain – which is secured to the Facility. The SWL of the mooring system is 200 tonnes. There is no weak link in the mooring system. The mooring is secured to the Facility in a Smit bracket which can be disconnected if required. Distance between the Terminal and the Loading Vessel once secured will be approximately 90 meters.

Pilotage is compulsory. The Terminal Pilot will normally board at the Pilot Boarding Ground approx 3 nm SE of the Terminal (LAT 04° 22.5' N LONG 007° 52.0' E ).The Loading Vessel shall provide a good lee to the prevailing sea and swell. The Terminal Pilots shall remain on the Offtake Vessel for the time the Vessel is moored at the Facility. Pilotage services are provided strictly subject to the Terminal Conditions. All manoeuvring of the Offtake Vessel is to be done on advice from the Terminal Pilot. However, Masters of the Offtake Vessel shall remain solely responsible for the safe manoeuvring of their vessels.

Berthing operations are restricted to daylight hours only. The latest time that mooring operations can commence will depend on the weather and the particulars of the Loading Vessel. Mooring shall be completed before darkness. Unmooring can be conducted at any time, weather permitting.

Irregular, predominately 070° direction at 7m depth and 200° direction at a 22.5m depth, averaging about 045° or 225° (from a DNV study). Tidal streams are also shown on the applicable Admiralty Charts

Tugs are available and essential for mooring.

Southwesterly to westerly winds predominate from May to September and are at their strongest average between 25 and 30 knots. From October to April the winds are variable and unpredictable in force and direction. From December to February winds are mainly from the north and their weakest average is 5 to 10 knots. Squalls of varying intensity are common between March and November. These squalls are unpredictable in force and direction and are accompanied by torrential rain, lighting, thunder and sudden shifts in wind direction. During these squalls winds speeds over 60 knots have been recorded. The squalls generally occur from the East but can in fact arrive from any direction. Masters are therefore advised to keep a sharp look out for these unexpected changes in the weather conditions, keeping engines ready at all times to be able to leave berth under full power on short notice. Throughout the year a long low southwesterly swells prevails. During the wet season, June to October, this swell together with rough seas becomes high, particularly during heavy squalls. The rainfall is very heavy with a yearly average of about 3700mm (150 inches). There are basically two seasons, a wet season from March to September and a dry season from October to February. Visibility can be very restricted during heavy rain and squalls. During the Harmattan season visibility occasionally drops to 4 to 5 cables for long periods of time. Fog is virtually nonexistent. If visibility is restricted the Terminal will advise the Offtake Vessel that the Terminal is closed and Offtake Vessel should remain well outside the Terminal area. The average temperature is between 28°C and 30°C. The daily range is from 22°C to 35°C. Relative humidity is high between 85% and 90%. Specific gravity of the seawater at the Facility location is 1.018 to 1.020. Surface sea temperature and Sea Bottom temperatures are both between 26°C and 29°C.
