Ward Operations High-Voltage Cable Jointing and Nitrogen Purging for Marine Sites
Ward Operations is a provider of high-voltage cable jointing solutions for application in offshore and other heavy industry environments.
In addition to having more than 25 years’ experience in delivering premium-quality products and installation procedures, the company also offers a range of specialist services to help prolong and optimise the operational functionality of cable products, including nitrogen purging and subsea cable repairs.
High-voltage cable jointing for oil and gas sites
Ward Operations supplies high-voltage jointing solutions for both paper-insulated and cross-linked polyethylene (XLPE) cables up to 132kV.
The company offers offshore cable termination units, as well as stacker / re-claimer reeling cables fitted with fibre-optic components to feed into slip ring compartments.
Ward Operations stocks a comprehensive array of joints and terminations in various sizes and voltage configurations, allowing the company to address clients’ specific needs and requirements across a versatile range of applications.
Subsea cable repairs for offshore environments
The company regularly carries out a number of specialised subsea cable joints and repair operations, due in part to the Queensland region’s prominence in the island tourism sector.
Ward Operations has been performing repairs and terminations for island feeder cables in and around the Whitsunday island vicinity for more than 30 years, including Hayman Island, Hamilton Island and South Molle Island.
This has allowed the company to accrue invaluable expertise and extensive knowledge of both the area’s unique properties and how to maximise the effectiveness of its marine operations.
Nitrogen purging services to increase cable lifespans
High-voltage cable nitrogen purging, is a unique, innovative process able to eliminate unwanted traces of moisture in XLPE-insulated conductors and cables, which has been proven to extend the service-life and functionality of such items.
This intricate, specialist service is carried out Ward Operations’ experienced team of licensed and highly trained cable jointers, and involves the introduction of 99% pure dry nitrogen with a dew point of roughly -80°C through cable fillers and conductors via carefully designated entry points.
Nitrogen purging is a meticulous process that may take several days of continuous operation to complete, and as such the company conducts the services on a job-by-job basis to ensure clients are given optimum consideration attention to detail.
Cables that have undergone nitrogen purging treatment have seen a dramatic improvement to insulation resistance (IR) and total acid number (TAN) test results, as well as enhanced performance and serviceability.
