A total of 45 people - 43 passengers and two crew - lost their lives when a Chinook helicopter crashed while approaching Sumburgh Airport in Shetland on November 6 1986.
The annual service of commemoration for all those who have died while working offshore was held in Aberdeen’s Kirk of St Nicholas on Saturday.
The service included an act of remembrance, where the names of those added to the book of remembrance were read out, followed by a piper’s lament and a minute’s silence.
Rev Pauline Nixon, whose husband Neville died in the Sumburgh disaster, offered a reflection, while Josh Watson, five, whose grandfather was killed, lit a candle.
Among others being remembered is Iain Stuart, 41, who was killed in a crash off the coast of Norway in April this year.
Rev Gordon Craig, chaplain to the oil and gas industry, said: “It is really important for families to realise their loved ones are still being remembered and respected by the industry. The service is an opportunity to commemorate all those no longer with us.
“Thirty years on from the Chinook crash may seem like a long time but the memories are still vivid for those who lost their loved ones suddenly and tragically. The pain may be more manageable but there will still be times when the loss is felt deeply.”
