Stephen Picken, 62, and Mark Kumar were working for Veolia ES (UK) Limited at an onshore facility in Great Yarmouth.

Both men were working as demolition operatives also known as “Top Men”, undertaking the decommissioning and dismantlement of offshore structures.

On 17 October 2019, the two workers were removing an overhanging piece of metal pipework (known as a skirt pile), weighing in excess of 27 tonnes, from a jacket (a structure placed in the sea, designed to support oil and gas rig platforms), when it gave way.

The pile struck the mobile elevating work platform containing the men, throwing them to the ground about 12 metres below.

Picken died at the scene and Kumar suffered serious life-changing injuries.

An HSE investigation identified serious failings with the planning and the risk assessment which did not adequately cover the planned works. Shortcomings in supervision of the incident were also identified.

The company did not risk assess the skirt pile being removed as it was considered low risk. As a result there was no cutting plan or safe system of work for the skirt pile.

Veolia ES (UK) Limited of London, pleaded guilty to safety breaches at Ipswich Crown Court this week and was fined £3,000,000 and ordered to pay £60,000 in costs.

After the hearing, HSE inspector David King said: “This incident, in an emerging industry, highlights the level of controls required to safely demolish what are large, dangerous structures. Veolia did not meet these standards and tragically one life was lost, and another forever changed.”
