Three Island Energy employees, who deny causing the deaths of ten islanders in an explosion at Haut du Mont in 2022, will return to the Royal Court in October.
Neil Armstrong (56), Lee Alan Ward (57) and John Mark Wright (59) have appeared in Jersey's Royal Court for the first time and have been remanded on bail until their next appearance in autumn.
Each of them has pleaded not guilty to ten counts of gross negligence manslaughter.
Advocates Tremoceiro, Blakeley and Boothman are representing the three men.

The three accused worked for the island's gas supplier at the time of the fatal blast at the flats on Pier Road in St Helier in the early hours of 10 December 2022.
Separately, Island Energy's CEO Graeme Millar also appeared before the Royal Court today and pleaded not guilty to two counts of breaching the Health and Safety at Work (Jersey) Law.
The charges are failing to ensure the health and safety of employees and failing to ensure the health and safety of people not in their employment.
Advocate Preston represents the company.
Both cases were adjourned until a directions hearing in October.
