High-voltage cable jointing for oil and gas sites

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.
