Serpentina (GQSER)

The terminal is composed of the FPU "Zafiro Producer", the "Jade" production/separation platform and the FPSO "Serpentina" in position 03°48.0'N 008°04.6'E. The SPM in position 03°52.2'N 008°17.0'E is no longer in use. There are also numerous flow and gas lines running from the FPU to the production wells. The Serpentina FPSO, 307,236DWT, is turret moored at the bow. Export tankers are loaded in a bow to stern tandem mooring configuration.

Tropical.

The FPSO is situated within the restricted area surrounding Zafiro Offshore Oil Terminal.

Offshore: LOA 340.01m, 315,221DWT.

Vessels may anchor in the designated area, with a depth of 64m, lying about 9.6km N of Zafiro Offshore Oil Terminal or in a similar depth about 3.2km W of the FPSO Serpentina. Vessels must not pass through the restricted area when proceeding to the anchorage.

Vessels are presently moored at the terminal FPSO using a 76mm chafe chain and a mooring hawser. The vessel needs to be equipped with at least one 200t AKD bow chain stopper and fairlead suitable for a 76mm chain. A 10in pick up line is heaved onboard until chafe chain is through the bow stopper. A crowbar and sledgehammer to be available on the foc'sle head. Vessel's port side derrick/crane min 15t SWL required for hose handling and 2 x 16in manifolds prepared for use. Combination ladder rigged on lee side for personnel access, 2m above the water. Mooring rope, heaving line, chain stopper, hammer and crowbar available on the poop for securing the tug wire of 64-77mm diameter, prior to approach to the FPSO. Masters are advised that the vessels crew are responsible for the connection/disconnection of cargo hoses under the supervision of the Pilot/Mooring Master. Mooring Party: Normally, a minimum of seven persons remain onboard throughout the loading operation and require accommodation. The party consists of two Pilot/Mooring Masters, one mooring Assistant, one Customs Official, one Independent surveyor, one Government surveyor and one Agency Representative. Weather Conditions: At the discretion of the Mooring Master, the max limits for berthing at the Serpentina Terminal are wind speed 25kts, swell/wave height 2.5m and max current 2kts. The max limits for remaining at the terminal are wind speed 35kts, wave height 3.5m and max current 3kts. Maintain weight on hawsers, High Alarm Setting 80t, High-High Alarm Setting 125t. The vessel must be maintained in a state of readiness to move at short notice.

Compulsory for export and FPSO and FSO bunkering Vessels. Provided by the Marine Department of Mobil Equatorial Guinea (MEGI), Tel: +1 214 589 6601 Pilots communicate with the vessel by VHF Ch 16/74 and use VHF Ch 67/68 for berth operations. Pilots will advise vessels of berthing intentions on receipt of ETA from arriving vessels. Normal boarding area is Pilot Boarding Station B (03°48.0'N 008°02.6'E), 2nm W of the FPSO. Pilots will normally board from one of the terminal supply vessels. However, if the vessel has a suitable helicopter landing area, the pilots prefer to board the vessel by twin engined helicopter during daylight hours only.

The FPSO "Serpentina" is taken as the point of reference. There is an Exclusion Zone of radius 0.27nm (500m) around the FPU, FPSO and SPM. The Zafiro Marine Terminal is bounded by a radius of 4.27nm from the FPSO "Zafiro Producer" and entry into the Development Area is granted as required by the "Zafiro Producer" radio room.

During the hours of darkness the FPSO Serpentina displays lights

Berthing in daylight only. Unberthing can be at any time.

Apr-Oct: mostly SW'ly; Nov-Mar: variable. The currents appear to be effected by local tidal conditions and may change direction and rate suddenly. This may delay mooring operations.

One tug available for towing at the FPSO and one for personnel transfer. A tug will be secured aft to assist in the approach to the terminal.

Currents: Variable in direction and speed, mainly running NE'ly at 0.5-1.5kts, liable to rapid changes in direction and speed without warning. Waves and swell (to 2.5m) are mostly SSW'ly Winds: The prevailing wind is SW'ly to W'ly, average speed 5-10kts, Mar-Nov 10-20kts. Squalls can occur at any time and can be extremely violent, especially between Apr and Oct. Between Dec and Mar visibility can be reduced to 400m due to the Harmattan wind bringing dust from the Sahara.
