Delta Doha Corporation is Qatar’s leading provider of custom designed and manufactured wellheads, Christmas trees and other oilfield equipment, and has full in-house capability to support local and international extracting contractors and oil and gas producers to manage complete pressure flow operations on site.
The company prides itself on delivering the most innovative and cost effective engineering designs and solutions, which range from design and manufacture to complete turnkey project management. A dedicated team of engineers, many with over 30 years’ experience in wellhead equipment handling and maintenance, provide a complete aftersales support service for clients worldwide. This includes field installation, maintenance and repair of any brand of equipment, and inspection services. Staff are continuously trained and developed to maintain their knowledge of leading edge developments in technology.
The Delta portfolio of products and services has been brought together and developed over the past 20 years through a series of strategic investments in equipment, facilities and personnel. In 1994 when Delta was originally acquired by Sheikh Sultan bin Jassem bin Mohammed Al-Thani and HH Sheikh Mohammed Bin Khalifa Al-Thani, it was the only local manufacturer and provider of oilfield equipment and services in the Middle East.
Years of investment and growth have followed. By 1998 Delta began to expand into the regional marketplace, first entering Oman and Kuwait, and then into the other Gulf Co-operation Council (GCC) countries. In 2008, recognising that there was a growing need for specialised welding and steel structure services in the region, the company formed a new subsidiary called Delta Fabco. A purpose built fabrication facility constructed at Um Salal, went into production that same year.
As part of its ongoing strategic growth plan, the company invested in two major construction projects in 2009. The first was the construction of a new corporate headquarters at Saliya, in Doha’s new industrial area. This is located just ten km from the main highway connecting the city with the Saudi road from the North. The second project was a major investment in the future of the business: a purpose built state-the-art manufacturing facility adjacent to the headquarters.
Approved by the American Petroleum Institute and operating to API Q1, ISO 9001 and ISO/TS29001 standards, the manufacturing plant is staffed by a team of highly qualified engineers and has the capacity to design and produce more than 150 customised wellheads and Christmas trees, as well as 800 valves, bulk piping and fittings per month. Field testing of the equipment is guaranteed, and carried out on the premises using the latest technology.
The final major investment in Delta services and capabilities took place in 2011, and incorporated a basic restructuring exercise. Responding to the growing demand for highly specialised engineering and maintenance support, Delta’s internal service and engineering capabilities were brought together in a single specialised subsidiary named Dserv. This provides maintenance consulting and support services to clients in the LNG and oil industries worldwide.
In parallel with this long-term development of technical capabilities, Delta has been expanding throughout the Middle East and into the global marketplace. Its location in Qatar, mid way along the eastern side of the Arabian Peninsula, is strategically excellent for international operations.
Qatar has strong transport links with all the major oil and gas production centres in the region and globally. A network of fast modern highways link it not only to the Gulf States but also with other key Middle East countries such as Yemen, Jordan, Oman, Iran Lebanon and Syria. The nation’s global air freight and international port facilities provide a reliable route for transporting products and personnel to destinations around the globe.
To embed company expertise overseas Delta opened its first overseas branch in Kuwait in 2010, specifically focusing on servicing the rapidly growing energy industries in Kuwait and Iraq. Expansion beyond the GCC states began with contracts in Africa, Asia and Russia, and has continued with the opening of a branch in the US in 2011 to supply Qatar-manufactured equipment and expertise to markets in South and North America.
All of this is based on the expertise and capabilities of the manufacturing facilities in Doha. Design, production and assembly take place in a fully air conditioned 5000 sq m manufacturing plant that is not yet five years old. To maintain this leading position the staff are continuously trained and equipment updated.
The engineering department is equipped with the latest 3D modelling, enabling engineers to combine Finite Element Analysis (FEA) with traditional design study procedures. The highly accurate meshing technique provided by FEA enables engineers to study complex shapes and models under virtual pressures and temperatures. The results are then compared and studied using traditional design processes. From this, the optimum product is achieved. The department also routinely uses 3D printing technology to facilitate innovation and speed up the design process.
Having created the optimum design, manufacturing is undertaken in a high tech centre equipped with over 40 of the latest machines. These include CNC machines capable of carrying out all types of precision operations, and large CNC horizontal boring machines with a pallet size of 2000mm x 1800mm for manufacturing dual blocks. All products are API monogrammed and strictly comply with the highest quality standards and health and safety measures. In addition, the plant is qualified and equipped to produce Sour Service products, with specialised coating.
At the after production stage, the plant boasts extensive assembly and test facilities. There are two benches for hydrostatic testing up to 15,000 psi and gas/nitrogen testing up to 20,000 psi. A horizontal test bench is provided for valves and equipment up to 16” and another bench analyses the performance of pressure valves. UT or radiographic inspection is performed for all product specification level three parts, and hardness testing for NACE service is carried out on all product specification levels.
The entire operation is supported by the Infor LN/Infor BAAN ERP system, which also manages quality documentation and traceability, from the raw material stage through to the end product.
In recent years, Delta has been through a significant period of investment and growth, which has equipped it to continue expanding both regionally and globally. Looking to the future, the company is well placed to support Qatar’s ambition to become the world’s largest exporter of LNG. Moreover its world-class facilities and capabilities are already contributing to the development of a centre of integrated energy expertise on the eastern coast of the Arabian Peninsula.
