New procedures after ferry crash
New safety procedures have been ordered following a collision between a ferry carrying 274 passengers and a cargo vessel on the River Mersey.
The accident, between the Isle of Man Steam Packet's Sea Express One and the Alaska Rainbow, happened in thick fog on 3 February.
The impact tore a large hole in the hull of the Sea Express One ferry which caused water to flood the engine room.
The Marine Accident Investigation Branch issued the recommendations.
It said the ferry crew only became aware of the Alaska Rainbow when a tug alongside it appeared out of the fog.
All the passengers escaped safely from the stricken ferry and the Steam Packet Company has adopted a number of measures as a result of its own internal review.
Ferry services resumed a month after the accident
There were no injuries on board the Alaska Rainbow, and damage to the vessel was minor.
Mark Woodward, the ferry company's chief executive, said: "The report confirms that our approved safety procedures were properly carried out.
"Evacuation was not necessary and passengers were disembarked safely in a timely manner."
The Steam Packet Company resumed sailings between the Isle of Man and Liverpool using Ben-My-Chree a month after the collision.
According to the investigators, the Sea Express One did not have a particular type of radar that could have provided an early warning of the position of the cargo vessel.
The report mentions that communications on the bridge were also impaired - initially by the presence of a trainee pilot and later by a lack of urgency from the main pilot in reporting the collision.
The Isle of Man Steam Packet company, which owns the high-speed vessel, have been asked to make sure safety instruction cards for life jackets match the type of life jacket on board.
The Alaska Rainbow did not make its position clear to the passenger ferry and there was a lack of support for each of the team members on the bridge.
The MAIB also said the Mersey radio team did not have an appropriate routine in place to cope with very bad weather.
