Shut down and
maintenance Servies

Everything you need to know about Green Mountains!

With utilizing a diverse multi skilled workforce, specialized equipment and services, GMET offers full shutdown and turnaround services under a single umbrella. Our teams of experienced engineers and planners work in partnership with the client from planning through to execution following the key shutdown drivers of Safety, Quality and Schedule. With our combined services GMET can execute full blind to blind services minimizing downtime with our range of cutting-edge technologies and highly trained staff. Offering the below services GMET deliver shutdown solutions to the Oil, Gas ,Petrochemical Industries, Power plant and Water treatment Plant :


In line with our commitment to the key drivers of Safety, Quality and Schedule, GMET oer the latest in remote jetting technologies. Targeted at removing heat exchangers from the critical path this equipment removes the operator from the high-pressure working end. 

This drastically reduces the risk whilst also permitting use of increased energy in a controlled fashion, to improve quality and reduce cleaning times. Operating multiple lances on individual exchangers cleaning times can be reduced by up to 4 times.


Air Cooled Condensers:

The same philosophy of remote jetting technologies is applied to cleaning of fins fans and vertically mounted Air-Cooled Condensers greatly   improving eciency and reducing production costs. GMET also oer foam cleaning and dry powder cleaning to provide the full range of options for improving fin fan eciency. 


GMET’s hydro milling services oer the best in pipe internal cleaning. Operating at up to 15,000psi and 70gpm the specially designed system can precisely clean large diameter pipework up to 72” negotiating multiple elbows and even vertical configurations.  The rotating hose system and specially designed cleaning heads ensure that the maximum cleaning force is delivered directly to the surface with precise control. Our technicians will design the cleaning heads for your specific application, be it detailed removal of mill scale to decoking process piping.


GMET integrates vast experience with the most advanced of equipment to provide outstanding results. Each project is pre-engineered to consider the optimal flow paths and chemistry tailored to the particular system metallurgy and contaminants, to design the safest and most ecient cleaning process. Our team of chemists control the process from our portable site laboratories located at the project site to ensure the cleaning is optimized and the client’s equipment protected at all times. 

GMET’s fleet of equipment includes truck mounted chemical circulators providing a small footprint and minimal set up time – ideal for heat exchangers. We also carry a fleet of pumps ranging  from 200 gpm  up to

4000gpm and storage tanks up to 80m3 capacity. Our equipment and pipework can be combined by our engineers to match up to any size system.

Performing Degreasing, Acid cleaning, Pickling, Solvent cleaning and other specialty chemical processes GMET oer the best chemical cleaning and corrosion protection solutions for heat exchangers, HRSG’s, furnaces, boilers, condensers and pipework for pre-commissioning and maintenance. 


GMET oers a comprehensive hydrocarbon decontamination package to the Oil, Gas and Petrochemical Industries. Utilizing a biodegradable chemical GMET will engineer in conjunction with client operations to accelerate the site shut down time and achieve.

ï     Zero LEL

ï     Zero H2S

ï     Benzene <1ppm

ï     Zero Pyrophoric Material

Compatible will all metallurgies the decontamination process will not only degas the units in accelerated but will also remove oil and sludge to reduce subsequent cleaning times. Operating in vapor or liquid phase GMET’s decontamination services will be engineered to suit the client specific needs including Crude, Vacuum, De-cooker, Hydro-cracker, Visbreaker, individual equipment, Tank form, Flare Network and Olefins units.


GMETs team of skilled catalysts technicians utilize the latest equipment and technology to perform blind to blind unloading and loading services for all types of catalyst reactors from driers to hydrocrackers and tubular reformers to Ethylene Oxide Reactors. Following a rigorous training program in our own simulator, our technicians acquire the skills to perform complex and arduous activities under inert conditions using the latest in Life Support Systems.

GMETs equipment is designed to provide the maximum eciency whilst minimizing catalyst attrition and exposure to personnel. Oering traditional sock loading methods alongside dense and uni dense loading technologies, GMET provides the full range of catalyst handling services for all situations.
