In today’s safety conscious work place, the preferred option is no-man entry into a confined space. Accordingly, NRC has developed a range of technologies and methods using tank cleaning heads, vacuum transfer systems and other pumping solutions to clean tanks and vessels either remotely or with minimum man entry.

Fully Trained, Skilled Workforce

At NRC our depth of knowledge in confined space and tank and vessel cleaning remains unsurpassed. We have a permanent workforce, fully trained and skilled in the safe working practices associated with confined space and tank and vessel cleaning. Technical support is provided by our experienced management team.

Tank Cleaning Heads

The use of specialist tank cleaning heads provide a remote cleaning solution allow for tanks and vessels to be cleaned with minimal requirement for man entry. We have a range of specialist cleaning heads which can be configured to meet the entry points of the tank / vessel.

Vacuum Transfer Systems and Pumping Solutions

For all confined space and tank and vessel cleaning the preferred solution would of course be one of no-man entry. For this purpose, our range of vacuum transfer systems and pumping solutions can be engineered / configured to meet the specific scope of work and specific gravity of material requiring removal thus ensuring optimum performance is achieved.

In the event of a man-entry requirement, our highly trained workforce specialises in all aspects of confined space entry and rescue. Equipped with an extensive range of breathing apparatus and gas monitoring equipment along with water-tight procedures and safe systems of work, ensure that our clients’ confined space working requirements are safely and efficiently carried out

All Industries and Applications Covered

NRC’s tank and vessel experience covers a broad spectrum of industries, onshore and offshore Oil & Gas, Petrochemical, Power, Utilities, Distilleries, Civils and applications including Cargo Tanks, Mud Tanks, Ballast Tanks, Production Separators, Silos, Fuel Tanks, Ducts, Boilers and Septic Tanks.

Confined Space Entry for Tank & Vessel Cleaning in the UK

Technology leads the way when it comes to solving the problem of safely and efficiently carrying out the cleaning of vessels and confined space entry.

Cleaning Managed Remotely or by Human Intervention

Because of the hazardous nature of confined space entry, we’ve developed a range of technologies and methods to safely clean tanks and vessels whether remotely or by human intervention. Many industries, including the oil and gas sector, have an ongoing need for safe cleaning of tanks and vessels. When muds, brines, sludges, sand, scale, waxes, sediment and other such deposits need removal, it’s often the case that human intervention is still necessary; our trained operatives have access to the most technologically advanced equipment available to do the job.

Highly Trained Operatives and Proven Safety Procedures

NRC’s specially trained teams utilise proven procedures to manage the risks associated with tank cleaning and confined space entry for industries both onshore and offshore. Combined with NRC’s Safe System of Work, this ensures all projects are safely and successfully completed.

Investing in Safety

NRC has invested heavily in breathing apparatus and equipment to ensure an absolute ‘fail safe’ operational methodology. The integrity of the primary air supply is constantly monitored by the standby man via the purification unit and/or breathing apparatus trolley. In the unlikely event that both of these systems failed the entrant is also equipped with an Escape set to ensure safe exit from the situation. Safety and quality have top priority in everything we do.

Specialist Confined Space Entry Equipment

An integrated range of specialist equipment has been assembled to maximise efficiency and minimise risk. NRC uses the latest technology in gas monitors, including portable multi-gas meters to monitor and display up to four gases simultaneously. Typically the carbon dioxide (CO2) and hydrogen sulphide (H2S) toxic sensors are used, but these can be changed in the event that a specific risk assessment identifies the potential of an alternative toxic hazard. Added safety features in this system include ultra bright alarm lights and a powerful audible alarm,which coupled with a periodic green flash and bleep provide users with the confidence that monitoring is always in operation and alarms are never missed. In the case of noisy environments vibrating alarms are used.

Our low pressure BA compressor units are used to provide quality, temperature controlled air which is constantly monitored. The failsafe system provides our operatives with peace of mind as well as comfortable breathing air whilst working on vessel entry operations.

Tank Management and Safety Support

During a shipyard visit or planned maintenance regime, NRC can provide essential support for all contractors who require vessel entry to carry out their work scope.
NRC has highly trained tank co-ordinators to enforce permitry controls and manage vessel entry. Using Safe Systems of Work (SSOW), tank coordinators use a point scoring system to ensure that tank entries are controlled at all times and do not clash with simultaneous operations within the vicinity.

Using temporary area gas monitoring equipment, NRC can also ensure that an entire installation or vessel is free from hazardous gases for the duration of a project. Real time gas readings are constantly monitored and recorded by designated tank co-ordinators within the remote permit office and an emergency response team actioned if gas levels exceed the identified ‘safe’ parameters.

Emergency Response Teams

NRC provides Emergency Response Teams (ERT), which are responsible for providing essential safety support during tank entry operations. Our team are highly trained and competent personnel who have considerable experience working within confined spaces, ensuring the appropriate reaction should an emergency occur. Associated Rope Access, when required, can also be provided on a subcontract basis. Combined with our specialist equipment and project specific rescue plans, our teams can provide a professional and comprehensive service.

Technical Overview & Specifications

All tank and vessel entries are potentially dangerous. Whenever possible, operatives will use remote cleaning techniques. If and when confined space entry is required, NRC personnel work under exact and detailed procedures, including task specific safety and escape routines using the correct breathing apparatus and atmospheric monitoring.

  • Innovative filtration process for the air purification unit converts compressed air to high quality breathing air
  • Monitors are calibrated in house to ensure operational integrity, irrespective of the conditions in which they are deployed
  • Lights, transformers and cables utilise multi-component Ex low voltage lighting system giving operational flexibility and enhanced safety
  • Three stage back up system provides consistent air supply – main air umbilical, trolley mounted cylinders and an escape set worn by the operative
