Visitors to the structure, located in Manhattan’s Hudson Yards complex, will no longer be able to enter alone, but its protective barriers will not be raised.

The Vessel, the labyrinth of staircases at Hudson Yards that closed four months ago after several people killed themselves there, will reopen on Friday with measures in place designed to reduce the risk of suicides.

But the Related Companies, the developer of Hudson Yards, said it would not raise the height of barriers along the sculpture’s walkways, a change that a local community board had been pushing for and that research has shown would be an effective deterrent.

Instead, security will be tripled, and visitors will no longer be allowed to hike up the steps of the Vessel alone. Those who wish to climb the 150-foot spiraling sculpture’s tangle of interlocking stairs will be required to enter in pairs or groups.

Staff will also be trained to watch for behavior that might indicate a person is considering self-harm...
