Solutions for Offshore Drilling
- Description
- References
Offshore drilling is a very important component of the fossil fuel production mix. However, with the days of easily accessible oil and gas fields becoming numbered, stakeholders involved in the offshore and subsea exploration and production of oil and gas are moving to even more harsh environments, requiring them to contend with tougher operating conditions, greater technological challenges and increased risks. All the more reason for choosing a partner with a proven track record of providing innovative oil and gas production solution packages that secure reliable operation and availability day in and day out, even under the most challenging conditions.
Concept, design and equipment solutions for offshore oil and gas drilling
The Siemens offering is based on broad expertise in power supply, drives, instrumentation, telecommunication (EIT) and water treatment as well as years of hands-on experience in the oil and gas business and subsea applications. The Siemens scope of supply covers all areas from conceptual development and decision-making to the entire lifecycle of the technology deployed, making it easier for all the stakeholders in offshore drilling to capitalize on their strengths and keep risks to an absolute minimum.
