HUMMINGBIRD OFFSHORE SOLUTIONS™
Oil and gas have been major trading commodities for many countries including Malaysia. Methods of producing fossil oil are various. Many oil fields are connected by pipelines laid on the seabed for transporting the oil and gas from the Centralised Production Platform (CPP) to refineries or export terminals located onshore. Some of the large oil fields are not connected to these networks of pipelines. The solution is by having Floating Production Storage and Offloading (FPSO) or Floating Storage and Offloading (FSO) for storage at field and acting as an oil terminal at offshore. When it has reached the storage capacity, the crude oil is offload from the FPSO or FSO into an export tanker.
In the last few years, as fewer large oil fields are discovered offshore, oil exploration in Malaysia has to go deep water where the water depth is more than 1 kilometre. The FSO or FPSO solution is the most suitable for these large oil fields. The solutions of using FSO or FPSO will require high Capital Expenditure (CAPEX). Hence it is not cost effective for marginal or small stranded oil fields where the daily output from the oil well is about 10% or less of the large oil field. A large oil field can produce more than 100,000 oil barrels per day.
A more viable and cost-effective solution is the Humming Bird Offshore Solutions™ concept. This solution is locally pioneered and currently being utilised by an oil major at approximately 200 kilometre North-West of offshore Bintulu, Sarawak. The Humming Bird Offshore Solutions™ concept is easily relocated from one marginal field to another. Its CAPEX is about 30% to 40% of the normal FSO or FPSO solutions. Another salient benefit of using the Humming Bird Offshore Solutions™ is its fast track characteristics. The whole system can be completed within 12 months from engineering until installation at offshore. This is less than half the time to complete the normal FSO or FPSO solution, which normally takes about 24 to 36 months.
The Humming Bird Offshore Solutions™ comprises of a Catenary Anchor Leg Mooring (CALM) buoy and Floating Storage Unit (FSU). The FSU, which is free to weathervane, is connected to the CALM buoy by a mooring hawser and the CALM buoy is secured to the seabed by six anchor chains. The simple mooring arrangement is faster to install and later decommissioned for transfer to other marginal fields.
