The 25th anniversary of the Piper Alpha disaster, in which 167 men died, is being remembered.

The North Sea tragedy happened on 6 July 1988 when explosions and a fireball ripped through the rig.

A rededication ceremony and remembrance service is being held at the Memorial Garden in Aberdeen’s Hazlehead Park on Saturday morning.

The garden, which opened in 1991, has been transformed after £150,000 was raised.

A Sea King helicopter from RAF Lossiemouth is expected to open the service by conducting a fly past at 11:00.

The ceremony will include a roll call of those lost in the disaster.

The tragedy shook the industry, and directly led to more than 100 changes in safety practices.

Since procedures were changed, fatalities have fallen.

Prime Minister David Cameron wrote to industry body Oil and Gas UK to mark the anniversary.

He said: “The 25th anniversary of the Piper Alpha disaster is a fitting moment to mark the skill, bravery and dedicated professionalism of all those who work offshore.

“We will never forget the 167 who lost their lives. And my thoughts as Aberdeen remembers its loss are with their families and loved ones, the survivors and all those involved on that tragic night.”

New generation

Meanwhile, an online educational resource to help teach pupils about Piper Alpha has been launched.

Accessed via the teachers’ intranet, it is an online space where teachers can share ideas and discuss approaches to including the disaster in lessons.

The site features interviews with survivors, and news and documentary content.

First Minister Alex Salmond said: “The 25th anniversary has rightly had a substantial emphasis in making sure that the new generation of offshore workers understand the importance of Piper Alpha in creating the current offshore safety regime.

“However, given that the oil industry will be with us for the next half century and more, we also have a responsibility to ensure that new generations of Scots understand the significance of the world’s worst offshore disaster.”
