Nitrogen Services
Nitrogen is an abundant gas forming approximately 78 % of the earths atmosphere. As an inert chemical it is both non-reactive and non-corrosive. Due to its properties, nitrogen is widely used in many industries to purge and condition systems. TES can apply nitrogen at various temperatures and pressures to assist with your project specific requirements while ensuring system limitations are respected and protected. Nitrogen related subsea services provided by TES include:
Purging and Inerting
Do you need to reduce lower explosive limits (LELs) to safe levels prior to commencing maintenance work? Do you need to purge process systems of oxygen prior to introducing explosive mixtures? Technical Energy Solutions (TES) conducts nitrogen purging and inerting to displace liquids and gases from process systems. Nitrogen is 99.9 % pure and has a dew point of – 90 °C dew point. TES can apply nitrogen at various temperatures and pressures to assist with your project specific requirements while ensuring system limitations are respected and protected.
TES will generate a project-specific engineered procedure combined with a risk assessment to enable safe and efficient field execution. By applying this methodical process TES helps you attain LEL or oxygen concentration targets. As is customary for TES, parameters are monitored and verified utilizing calibrated instruments to drive safe and efficient operations.
Well applications
Do you need to conduct a well clean-out? Do you require high pressure nitrogen charging of well annulus for gas lift assistance? Technical Energy Solutions (TES) conducts nitrogen pumping to support downhole applications. For subsea applications, TES provides certified downlines and subsea panels for intervention via remote operated vehicle (ROV).
TES will generate a project-specific engineered procedure combined with a risk assessment to enable safe and efficient field execution. By applying this methodical approach, TES helps you execute your exploration, intervention, and decommissioning requirements. As is customary for TES, parameters are monitored and verified utilizing calibrated instruments to drive safe and efficient operations.
Nitrogen is often shipped as a cryogenic liquid with a boiling point near -196 °C. Specialized vaporization and pumping equipment is utilized to vaporize and apply nitrogen at predetermined temperature, pressure, and flow conditions. Gaseous nitrogen can also be shipped in pressurized containment vessels and applied at predetermined conditions.
Due to its physical properties, nitrogen also poses hazards that must be diligently managed. These include, extreme temperatures, extreme pressures, and asphyxiation risk. TES has the knowledge and experience to enable safe and efficient field application
of nitrogen services.
