Leads has been actively engaged in pre‐design surveys,specialized surveys, supply of materials, design, installation, energizing, testing and commissioning, monitoring and trouble shooting of a wide range of cathodic protection projects.Typically, industrial cathodic protection involves structures such as underground and aboveground storage tanks, buried pipelines, oil well casings and structures associated with refineries, power plants, water treatment and desalination plants, etc.

Leads has wide-ranging experience of the following types of protection:

  • Temporary Cathodic Protection
  • Permanent Cathodic Protection
  • Sacrificial Cathodic Protection
  • Impressed Current Cathodic Protection

Leads have successfully completed various offshore projects such as surveys, design, testing and commissioning, research and development on a project basis and supply of materials. Our engineers have experience in ROV surveys, design of monitoring systems and retrofits for ageing offshore structures and pipelines. Some of the typical offshore structures for corrosion protection have been:

  • Submerged pipelines
  • Dry Docks
  • Jetties Fixed and floating Offshore Jackets
  • Single Buoy Moorings

Leads have been actively involved in various activities for offshore structures including surveys, design, testing and commissioning, research and development on a project basis, supply of materials (bracelets and other type of anodes).

The corrosion engineers of Leads are amongst the world’s leading experts in the field of deterioration and repair of reinforced concrete structures of all types.Leads possesses unrivalled expertise in the field of corrosion surveys, potential mapping, corrosion rate surveys, design and specification services, materials supply, installation, commissioning and maintenance of cathodic protection systems for steel reinforced concrete structures.These services have been successfully implemented on a wide range of structures such as power plants, seawater cooling systems, bridges, docks, etc.

In addition to providing such services to existing deteriorated structures, Leads also provides a similar service for construction of new concrete structures that will prevent the onset of reinforcement corrosion in an economic way.

Leads engineers can provide detailed audits of cathodic protection systems, interference investigation or pipeline integrity assessment surveys.Leads have completed complex evaluations of defective cathodic protection systems in plant and on pipelines. For pipelines, a complete Coating Defect Assessment Survey may include a Close Interval Potential Survey (CIPS), Direct Current Voltage Gradient Survey (DCVGS), PCM survey, soil resistivity and soil analysis to provide defect priority ranking and earmark selective coating defects for excavation and rehabilitation. Leads also follow External Corrosion Direct Assessment (ECDA) procedures as set out in current NACE standards.

Leads engineers have carried out FEED studies and consultancy services on major projects. These include pipelines, well casings, tank farms and corrosion assessment of reinforced concrete structures. Leads are licensees of Safe Engineering Systems (SES) Right of Way Pro ™ software which is used for modeling induced AC voltages on pipelines close to high voltage power lines. Predictions from computer modeling have shown good correlation with site experience. Leads also work closely with UK Computer modeling specialists BEASY who can provide predictions on current and potential distribution as well as predicting interference with impressed current cathodic protection systems.

Leads companies manufacture a wide range of products used in cathodic protection. We also have supply agreements with many specialist suppliers which enable us to offer a complete range of cathodic protection materials and associated products. Our global manufacturing locations enable us to offer competitive pricing with consistent quality wherever our products are manufactured.

Amongst the products manufactured or assembled in-house we can include:

  • Transformer-rectifier units
  • Remote monitoring and control systems
  • MMO and impressed current anodes
  • Magnesium anodes
  • Junction boxes and test posts

Other products supplied through partners include:

  • Monobloc Isolating joints
  • Surge Arrestors
  • Polarisation Cell Replacements
  • Specialist CP cables

Leads provide remote monitoring electronics and software for corrosion related applications. Remote monitoring provides companies with a cost‐effective way to monitor the operational status of their corrosion protection systems. Data is collected by the remote monitoring unit and then transmitted utilizing various communications channels, including fibre optic cables, cellular phones and low earth orbiting satellites. Remote monitoring reduces or eliminates the need for companies to send personnel on‐site in order to monitor corrosion protection systems on a variety of structures, including pipelines, storage tanks and reinforced concrete structures. Data collected via the remote monitoring units can also be utilized by risk assessment and management software in order to provide customers with a comprehensive corrosion monitoring program.

The product range includes:

  • Remote Monitoring Units (RMU)
  • Remotely Controlled Power Supplies
  • Data Loggers
  • GPS Interrupters and Locators
  • Associated Software for Data Management
