Caribbean FLNG Project – Setting the Stage


Caribbean FLNG Project Background� Pacific Rubiales Energy (PRE) via its

subsidiary Pacific Stratus Energy Colombia Corp. (PSE), signed a natural gas/ LNG Liquefaction, Storage and Loading Services Agreement with Belgium based EXMAR NV:− EXMAR will build, operate and maintain a Floating

Liquefaction & Storage Unit (FLNG) to be located on the Colombian Caribbean coast.

− PSE will have exclusive rights to supply and liquefy up to 0.5 mmtpa of LNG over a 15 year period, under a tolling structure.

� The source of the gas is PSE’s La Creciente Field.

� PSE will build an 18 inch pipeline to transport gas from the field to the coast (88 Km).


The FLNG Solution

� Selected FLNG solution is a non-propelled barge moored to an offshore jetty.

� FLNG is to be located 4 Km offshore in 14 m water depth.

� FLNG storage and process requirements are:- Storage - 16,000 m3

- Liquefaction - 0.5mmtpa

� Alongside FLNG is 170,000 m3 LNG Floating Storage Unit (FSU).

Regasification option:

� 65% of Colombia’s electricity comes from hydropower.

� In some years (la Nina) water shortages may require importing LNG to generate power to maintain supply.


� Wison is the primary EPCIC contractor to EXMAR for the barge-based FLNG.

� Wison’s Scope:− FLNG Project Management,

Engineering, Procurement, Construction, Commissioning, Transportation, Installation and Start-up of the Facility.

� Major subcontractors : - Black & Veatch: Topside

LNG Equipment Design, Procurement & Commissioning

- TGE: Cargo Tanks & Cargo Handling Systems

FLRSU Project Details and Wison Scope


Transportation & Installation

� Following yard commissioning, FLNG will be loaded onto transport vessel for dry transport to Colombia.

� FLRSU will be offloaded at inshore location and wet-towed to final installation site.

� Permanent mooring brackets will be installed while temporarily moored at site.

� Gas export hoses will be installed from jetty to FLNG.

Voyage: ~13,000 n.miles


Barge FLNG Applications

� Complete LNG plant in a single module.� Near-shore processing in sufficient depth to transfer

to LNGC.� Eliminates/reduces need for a cryogenic load

out jetty.� Storage on board, onshore LNG tanks not

required.� Both on-shore and off-shore feed gas.� Gravity based structures.� Ports or on land.

PRICO® SMR Liquefaction Technology

� Black & Veatch’s patented PRICO® Single Mixed Refrigerant technology is the simplest form of mixed refrigerant cycle.

� B&V has considerable experience in the field:

- 27 global LNG plants in operation

- 11 plants under construction

� Process is scalable over wide capacity range but core process remains the same.

� Compact layout with modular philosophy lends itself to use offshore.

� Simplicity of process results in relatively low cost.

� Simplified operations lead to quick startup.


Dealing With The Gas

� Slug catcher on inlet. � CO2 must be less than 50ppm before entering the main heat exchanger.

� Membrane and amine systems.� Dealing with CO2

� N2 is dealt with in the BOG.� Heavies removed in the BAHX.

� LPGs, condensate stabilisation, NGLs. � Product Storage.� Inlet Booster compression.


Main Exchanger – BAHX “Cold Box”� Aluminum plate fin exchangers (cores) in

parallel� Strictly use external connections� No valves or equipment in cold box� Cold box is for insulation / support only� Plate fins are highly efficient and reliable� More than half with 30+ years of service (no

repairs)� Design vetted by ExxonMobil – approved

offshore applications� Down flow condensing / up flow boiling� Refrigerant & feed gas condensing flowing

downward� Low pressure refrigerant boils in up flow� Simplified hydraulics – working with gravity� Cold end down� Upon shutdown, cold liquid stays in

cryogenic area of the core� No cold liquid flows in to warm part of the

exchanger� No special precautions in case of shut down

Summary & Conclusions� For an FLNG unit the storage

volume requirement as well as the tank type selected has a significant effect on the topside lay-out and how the equipment is configured.

� The type of offloading equipment selected impacts the lay-out of the topside as well as set some of the crane coverage requirements.

� Safety studies are required for an FLNG unit to become reality. These impact spacing, lay-out principles and cryogenic spill protection as well as mechanical handling etc.
