An offshore union is targeting the operator of a helicopter which crashed into the North Sea killing four people.
The National Union of Rail, Maritime and Transport Workers (RMT) plans to hold a protest at the Aberdeen heliport of Super Puma operator CHC.
One of its helicopters came down off the southern tip of Shetland on Friday night, prompting renewed industry concern about safety. It was the fifth incident involving Super Pumas in the North Sea since 2009.
Union general secretary Bob Crow, who will attend the protest joined by Norwegian colleagues, said: "No one should underestimate the level of grief and anger felt amongst the offshore workforce in light of Friday night's latest disaster.
"That anger can be seen across the social media sites. Twenty-five years after Piper Alpha, the industry is today confronted by another series of basic demands and assurances on worker safety.
"The time has come for the offshore industry to start treating their workforce with respect and dignity, and that means no more hollow words on safety and a lifting of the ban on union access to the workforce."
The protest is planned for 7.30am at Aberdeen airport, the RMT said.
The plan emerged as the body of the fourth victim of the crash was brought to the mainland. A search for the aircraft's black box data recorder, which was located in the helicopter's tail section, is being carried out by salvage experts at the site of the crash using specialist sonar equipment.
There were 16 passengers and two crew on the Super Puma AS332 L2 travelling from the Borgsten Dolphin support vessel when it crashed into the sea, killing three men and one woman.
The victims were named as Duncan Munro, 46, from Bishop Auckland, County Durham; George Allison, 57, from Winchester, Hampshire; Sarah Darnley, 45, from Elgin, Moray; and 59-year-old Gary McCrossan, from Inverness.
