Dutch vessel blamed for Guyana subsea cable outage

In: Interconnectors

A Dutch transport vessel has been reported as the cause of the damage to the Guyana Power and Light’s (GPL) Demerara River subsea power cable, which occurred late November. The 69kV subsea cable links GPL’s Vreed-en-Hoop and Kingston substations and maintains a stable supply of electricity for the coast communities of Guyana.

The cable went offline in November, leaving locals without power. The cause of the outage has been attributed to the Dutch-flagged transport vessel NLIST DLEP which dropped its anchor in the vicinity of the cable causing damage to the cable, onshore transmission and distribution infrastructure. Repairs got underway earlier month restoring power supply.

This isn't the first time the subsea cable connection has suffered damage since its installation back in 2012. In June and August 2019, the cable suffered severe damage. It was subsequently restored in October.

As a result of the cable being damaged on multiple occasions, MARAD has issued restrictions aimed at preventing vessels from anchoring close to the cable. Vessel operators are now required not to anchor within 200 metres of the subsea link, in order to prevent similar incidents from occurring.
