Case Studies

Prelude will be the world's first floating liquefied natural gas platform as well as the largest offshore facility ever constructed. She will be 488 meters (1,601 feet) long, 74 meters (243 feet) wide, and made with more than 260,000 tons of steel. At full load, she will displace more than 600,000 tons.

The Prelude will eventually be anchored in the Concerto gas fields in the Browse LNG Basin 200 kilometers (120 mi) off the coast of Australia. It has a planned life expectancy of 25 years.

COENS has supplied manpower to this project via multiple parties involved in the project as well as being one of the main service providers for accommodation and transportation. We have supported the project in both Geoje, South Korea.

The Barzan Project will be the largest gas train project constructed to date and consists of 2 trains as well as an offshore platform for Phase I. The project will produce and process gas from Qatar's North Field for use domestically to address Qatar's growing energy needs.

COENS relationship with the partners involved allowed them to enter and support this project from an early stage. We supported the project through the provision of manpower at all locations, Kuala Lumpur, Malaysia, Ulsan, South Korea and Doha, Qatar, as well as through the provision of services.

Sitting just 50km from the Arctic Circle in 350-450m of harsh waters, the Skarv FPSO is a milestone for BP. It is the firm's first greenfield project in its Norwegian unit since the Tambar field came on stream in 2001 and is thought to be one of the most northerly of the group's global developments. According to BP, it is the world's largest harsh-water floating production, storage and offloading vessel, at 295m long, 51m wide and weighing in at 74,000 tons. It has a storage capacity of 875,000 barrels, oil production capacity of 85,000 b/d and gas production capacity of 19MM cu m/d (670MMscf/d).
COENS provided multi-disciplined manpower across all locations, Geoje, South Korea and Stord, Norway , as well as having a service provision contract.
The next stage of the Sakhalin I Project is the development of Arkutun-Dagi field located at a distance of 25 km from the shore North-East off Sakhalin Island and Eastward of Chayvo field.
Arkutun-Dagi operations will be developed in phases. The crude oil will be sent to the Chayvo Onshore Processing Facility for treatment and then delivered via a pipeline to De-Kastri for export.
Exxon Neftegas Limited has successfully and safely completed the installation of the Berkut platform topsides onto the gravity-based structure at the Arkutun-Dagi field in June. This operation has set a world record for the heaviest integrated topsides installed by float-over method in open sea.
The Arkutun-Dagi field development will help maintain Sakhalin I production. The production start-up of Arkutun-Dagi began in January 2015.
COENS has supplied manpower to this project via multiple parties involved in the project as well as being one of the main service providers for accommodation, transportation, logistical and procurement. We have supported the project in Geoje, South Korea and Yuhzno, Sakhalin (Russia), as well as offshore Sakhalin Island (Russia).

The Ichthys project is an AUD 34 billion, 2 trains, 8.4 million tons of LNG per annum, 1.6 million tons of LPG per annum, along with more than 100,000 barrels of condensate per day at peak.
Gas condensate from the Ichthys Field will be exported to onshore facilities for processing near Darwin via an 889 km pipeline. Most condensate will be directly shipped to global markets from a floating production, storage and offloading facility permanently moored near the Ichthys Field in the Browse Basin.

It is a complex project involving 3 distinct phases:
1. Offshore facilities ? Central Processing Facility and FPSO;
2. Offshore Gas Export Pipeline - 890km from offshore facilities to Darwin;
3. Onshore Processing Plant - based in Darwin.

COENS has actively been involved in this project since 2013, through the provision of manpower and other services across multiple locations, such as Geoje, South Korea and Qingdao, China.
Installation of the 30,000 ton topside and platform, which accommodates 200 people along with drilling and production equipment, is operated by a consortium led by Daewoo International. The project, 70 km (43.5 mi) offshore Myanmar, will produce and process up to 500 MMcf/d of gas for export to China.
COENS received a single source project management contract for the provision of manpower and services covering the fabrication stage as well as the operation and maintenance period after installation. COENS also have provided accommodation and transportation services related to the support of the manpower.
The support of this project during the design and fabrication period included Paris, France and Ulsan, South Korea. While the operation and maintenance period is being supported by our office and in country staff in Yangon, Myanmar.

The Usan Project was a new field development in 750 m water depth and 100 km south of the Nigerian coast. USAN has been developed with 42 subsea wells connected to a 2 MMbbls storage FPSO via 2 production loops, 2 water injection lines and 1 gas injection line.

At 320 m (1,050 ft.) long by 61 m (200 ft.) wide, the FPSO Usan is one of the largest in the world and can process 180,000 b/d of oil, 5 MMcm/d (176.6 MMcf/d) of gas. The OML 138 block in Nigeria contains the USAN field which started production in February 2012.

COENS provided contractors during the fabrication stage in the Hyundai Heavy Industry yard in Ulsan, South Korea as well as support services. We continued our support of the project both in Lagos, Nigeria as well as at block OML 138, offshore the Nigerian coast during the hook-up and commissioning phase.

Jointly owned by Imperial Oil (operator) and ExxonMobil Canada, the Kearl oil sands project will produce one of the largest and highest quality oil sands deposits in Canada. Diluted bitumen production started at the end of 2013 at a projected initial production level of 110,000 barrels per day (bpd). At full development, Kearl is expected to produce almost 500,000 bpd of diluted bitumen.

Kearl will be connected to the substantial North American pipeline system. Kearl diluted bitumen can be transported straight to refineries that are already configured to process heavy oil and bitumen. Additional logistics are under development that will further expand outlets to the U.S. Gulf, mid-continent, and Far East markets.

The fabrication of the modules occurred at the Hyundai Heavy Industry yard in Ulsan, South Korea. COENS provided manpower for the fabrication phase as well as for the transport phase through Montana in the USA and on to Alberta, Canada for the re-assembly and commissioning phase.
