1.1. Minimum visibility for mooring and unmooring:

Minimum visibility to start the mooring: 5 nautical miles Minimum visibility to unmoor: 3 nautical miles.

Maximum admissible wind speed: 25 m/s (wind coming from the West)

1.4. Mooring maneuvers time:

Vessels under 70.000 DWT: They can moor at night when the wind speed does not exceed 5 m/s and/or the wave height does not surpass 0,5 meters.

Vessel above 70.000 DWT: They can only moor during daylight time.

Olivia SPM Maximum admitted DWT 150,000 DWT 150,000 DWT Minimum admitted DWT 39,000 DWT 39,000 DWT Environmental conditions envisaged: - Depth 37.14 m (121.8') 42.34 m (138.9') - Range of the tide 5.98 m (19.6') 5.98 m (19.6') - Wind speed 25.72 m/s (50 knots) 25.72 m/s (50 knots) - Current speed 55 m/s (1.07 knots) .55 m/s (1.07 knots) - Maximum wave height 6.30 m (20.6') 5.00 m (16.4') 3. MOORING SYSTEM AND HOSE LAYOUT LIMITS Both SPMs MAXIMUM ALLOWED DRAFT 18.0 m (59') MAXIMUM BOW-MANIFOLD DISTANCE 148.5 m (487.2') MINIMUM BOW-MANIFOLD DISTANCE 92.0 m (301.8') HOSE LIFTING EQUIPMENT CAPACITY (SWL): Dead weight tonnage, 39,000 to 60,000 DWT 10 tons Dead weight tonnage, from 61,000 to 150,000 DWT 15 tons CONNECTION FLANGE AT TANKER HOSE 16" MANIFOLD ARRANGEMENT OCIMF 76mm CHAIN STOPPER ACCORDING TO OCIMF 1 x SWL: 200 tons. FLOATING HOSE CONNECTION TO VESSEL: - Caleta Olivia SPM Port - Caleta Córdova SPM Starboard It is required that the Lifting Vessels have mooring systems and manifold arrangements according to the requirements of OCIMF (Oil Companies International Maritime Forum) included in "Recommendations for equipment employed in the mooring of ships at single point moorings", third edition, 1993, and "Mooring equipment guidelines", second edition, 1997. The following features may be highlighted in the above publications:

Deck equipment: � Distance between stopper - forward fairlead: 2.7 to 3.7 m. � Stopper characteristics: SWL 200 tons, to secure 76mm chain. Throat section: 322 - 330mm x 356

- 360mm. � Since only a single chain is used for mooring, it is deemed advisable to use a stopper and a central

fairlead. � A Smit Bracket may not be used. � For the exceptional mooring of vessels with 54mm stoppers, advance notice will be required, as

well as agreement to pay for the mooring chain change service according to TERMAP S.A. scale of charges for services provided to vessels.

Manifold equipment: � Horizontal distance between manifold flange-side of ship: 4.6 m � Maximum height of flange center on main deck: 2.1 m � Minimum distance between manifold flange centers: 2.0 m � Distance between connection flange center to drip trays: 0.9 m (#)

(#) Due to the use of a 16" double carcass connection hose (1.4 m outside diameter), vessels failing to comply with this last requirement shall not be connected.

4. OPERATIONAL SAFETY REASONS LIMITS The mooring service provided by the Terminal includes a mooring vessel and a support tugboat. All operations are performed with the assistance of the tugboat in order to keep the mooring hawser tight and a safety distance between the buoy and the tanker's bow. The buoys have a control system of the operational parameters, which is radio-linked with the Tank Farm and the support tugboat. This telemetry system has automatic warning signals in which reference values have been set for the Mooring and Loading Master. Operations will be suspended and vessel unmooring will take place when the mooring hawser tension (because the meteorological and sea conditions) exceeds 80 tons. in repeated readings, the tension tendency is in crescent and the immediate weather forecast is unfavorable. When the system is not operative, or a spare buoy without telemetry system (replacement) is in use, the unmooring will be realized the wind surpass the limit established by the PNA. It is required that all vessels have an inert gas system for treating their tank atmosphere. Mooring Masters shall only authorize mooring of vessels having tank atmospheres with 8% or less O2 content by volume. Vessels that, due to the number, volume and layout of cargo tanks, cannot load at the loading rate agreed upon between Terminal and Producers in the relevant Rules, may be unmoored so as not to delay the next vessel coming up within the agreed time window, and finish loading when the schedule of vessels allows so. In order to avoid a new nomination of vessels failing to comply with the requirements of the Company, the Vessel Commanding Officer, Producers or Shipowners, Charterers or Freight Agents, shall be duly advised of the reasons why they are disqualified from operating with the Company.

The Vessel Commanding Officer shall accept in written, the Conditions of Use of Terminals and Services, as indicated in the new forms and appendices to the Port Rules to be published shortly. 5. MOORING MASTER All vessel operations shall be decided by the Mooring Master, who will consider whether the mooring and/or stay of the vessel at the Terminal are safe for the staff, the environment and the facilities, and whether it meets the requirements established by TERMAP S.A. in its Port Rules. 6. ADITIONAL LIMITS TERMAP S.A. reserves the right to establish new limitations at its Maritime Terminals whenever conditions are detected during the operations of Vessels that may threaten the safety of the facilities or of the environment. 7. INFORMATION FOR VESSEL NOMINATION All Vessels operating at the Caleta Córdova and Caleta Olivia Terminals shall be nominated in advance by furnishing the following data: Present vessel name and ex name Type of vessel Flag Loading Terminal Laytime envisaged for the operation Vessel intended Agents Vessel Owner Volume of oil to be loaded Deadweight tonnage (DWT) to maximum summer draft Length overall Beam Molded depth Maximum (summer) draft Distance bow-to-center manifold (BCM) Manifold arrangement (OCIMF) Mooring stopper characteristics (76mm) Arrangement of mooring equipment (OCIMF) Lifting capacity of tackles in the manifold area Manifold connection flange diameter Inert Gas System for tanks Automatic system for ullage and overflow warning. Ballast type and quantity Number of cargo tanks available Name of insurance company or P&I Club Name and telephone of an Oil Spill Response Company that will start, at the latest, 24 hours

after the incident, with spill control and cleaning of the area (not applicable to cargo of vessels included in the CCI - Convenio de Cooperación Interempresario).

Name, telephone and E-mail address of the "Vetting Service" of some major oil company in which the nominated vessel is registered as "Acceptable". Expiration date of its certificate.

Acceptance of the use of Services provided by the Terminal. If Terminal services are not going to be used, name of the Contractor rendering the service, who shall secure TERMAP.'s prior authorization of the support operations in order to meet the safety conditions concerning the staff, the environment and the facilities required by the Company.

8. COMMUNICATIONS Caleta Córdova and Caleta Olivia Terminals shall be listening in in channel 9 (VHF marine frequency) when no Vessels are operating at the SPMs. Once contact between the Vessel and the Terminal has been established through that channel, each Terminal shall change only to the operational channel authorized by the Company, as follows: Caleta Córdova: VHF Marine Channel 68 Caleta Olivia: VHF Marine Channel 69 E:\JMARZOCC\DATOS\WORD\Reglamento portuario y limites\Reglamento portuario 2005\ANEXOS 2005\Anexo 5\ingles
