Prelude (AUPRL)

FLNG 'Prelude' is a floating hydrocarbon (LNG, LPG and Condensate) production, storage and offtake facility. Facility can produce 3.6million tonnes per annum (mtpa) of LNG, 1.49mtpa of condensate and 0.4mtpa of LPG. The vessel structure is 488m long and 74m wide, making it the largest offshore floating facility ever built. The facility's storage tanks, located below the deck, can store up to 220,000mі of LNG, 90,000mі of LPG and 126,000mі of condense. Shell has 67.5% interest in Prelude. Partners include Inpex Corporation with a 17.5% stake, Korea Gas Corporation with 10%, and CPC Corporation with 5%. The FLNG 'Prelude' facility is in close proximity to FPSO 'Ichthys Venturer' (see separate entry). Both projects draw from separate fields, Prelude and Ichthys respectively, but could share gas at a reservoir which may straddle both Fields depending on the positioning and timing of the Projects' separate drilling programmes.

Summer.

FLNG 'Prelude' is located at Prelude field, approximately 475km NNE of Broome in Western Australia.

Tankers should not approach within 6 nautical miles of Prelude until such time as it is progressing to the Pilot Boarding Ground. When approaching Prelude, vessels should so far as possible avoid passing through the ICHTHYS field. A wave buoy is established in position: Latitude (WGS84): 13° 49' 1.028" S Longitude (WGS84): 123° 16' 49.289" E. There is a 500m exclusion zone around this wave buoy. The TTL will contact the tanker on VHF channel 68 prior to departing Prelude. The TTL will advise the tanker when to commence its approach to the Pilot Boarding Ground. Under no circumstances should the vessel enter the 1500m safety zone without the express permission from the TTL and only then when the Infield Support Vessels (ISVs) are in attendance.

Mooring of a tanker is restricted to daylight hours only. Daylight is considered between morning and evening civil twilight. Unmooring is permitted in daylight and night-time conditions.

Pilotage is compulsory for all vessels arriving and departing at Prelude. All vessels shall stay at least 6 nautical miles from the Prelude until such time they are requested to proceed to the Pilot Boarding Ground. The pilot boarding ground is 3 nautical miles directly astern of Prelude or as advised by the TTL once radio contact is mad.

The climate of the region is monsoonal, and displays two distinct seasons, “winter” from April to September and “summer” from October to March, with very short transition seasons, generally in April and September/October between the two main seasons. The winter is generally dry due to South East Trade Winds coming from the Australian mainland. The summer is wet as a result of the North-West Monsoon. Occasional tropical cyclones occur during these months and result in short-lived, severe storm events, often with strong but variable winds. The summer (October – March) monsoonal surges and associated convective squalls, are also prevalent (although less severe than cyclones). Tropical cyclones originate from south of the equator in the eastern Indian Ocean and in the Timor and Arafura Seas. They occur during the predominantly summer months November to April, being most active in the months of December to March. The most severe cyclones will most often occur in the months of December and March-April, when sea-surface temperatures are warmest. Ambient wave conditions are dominated by swell propagating from the Indian Ocean, together with local wind-sea generated by the monsoonal winds. This can lead to significant angular differences between wind-sea and swell.

"Prelude Terminal" VHF Ch 68/16.

The Master of the tanker is required to provide Notice of Readiness (NOR) to load condensate when the tanker: (a) has arrived at the Pilot Boarding Ground or such other point located at or proximate to Prelude as may be advised by the Prelude Operator; (b) has received all necessary clearances; and (c) is able to receive condensate for loading. The NOR will be delivered by the Master of the tanker Ship to the Prelude Operator by electronic mail (email) at the following email address: Prelude Operator: Prelude-TTL@shell.com and Prelude-PTL@shell.com Tel: +61 (0)8 6383-1771, +61 (0)8 6383-1772, +61(0)8 6383-1773 and +61(0)8 6383-1781 In addition, the NOR may be handed to the TTL after the TTL has boarded the tanker, in which case, NOR is effective: (a) for a condensate ship giving its NOR at its Required Arrival Time, NOR is effective at that Required Arrival Time; (b) for a condensate ship giving its NOR after its Required Arrival Time, NOR is effective when the TTL boards, following the Prelude Operator’s notice to the tanker that Prelude is ready to receive the TANKER for loading; or (c) for a condensate ship giving its NOR before its Required Arrival Time, the earlier of either: i. the Required Arrival Time, or ii. when the TTL boards, following the Prelude Operator’s notice to the tanker that Prelude is ready to receive the condensate for loading.
