The mothership that launched the doomed Titan submersible has returned to port in Canada, following the sub’s catastrophic implosion during a dive to the Titanic wreckage.
The Polar Prince support vessel arrived in St John’s Harbor, Newfoundland, on Saturday morning, docking at about 8.15am local time as sun broke through the morning haze.
Crew members in orange hard hats were seen on the deck of the vessel, which departed eight days ago with 24 people aboard, five of whom were killed in the sub disaster.
Police and safety investigators could be seen boarding the vessel after the Transportation Safety Board (TSB) of Canada announced it was launching a probe into the fatal implosion of the deep sea vessel.
The Polar Prince had taken part in a massive search effort for the Titan about 435 miles south of St John’s, which came to an end on Thursday with the confirmation the sub had imploded deep underwater, likely soon after it launched on Sunday.

Rib boats were also spotted towing what appeared to be the Titan submersible’s launch platform away from the Polar Prince and further along the port.
The Polar Prince is a decommissioned Canadian Coast Guard icebreaker now owned by Miawpukek Horizon Maritime Service Ltd, and chartered by extreme tourism company OceanGate as a support vessel for the Titan’s fatal dive.
OceanGate founder and CEO Stockton Rush was killed aboard the American company’s submersible, along with prominent British Pakistani businessman Shahzada Dawood and his son Suleman Dawood, British adventurer Hamish Harding, and French Titanic expert Paul-Henri Nargeolet.
Two Canadian Coast Guard (CCG) vessels that took part in the search effort also returned to St John’s harbor on Friday evening, with one remaining on site at the scene of the disaster.
A crowd gathered by the dock to watch the return of the CCGS Terry Fox and CCGS Ann Harvey, while the CCGS John Cabot remained on site provide assistance and support to the recovery and salvage operations.
In a statement issued before their ships arrived at the port, the CCG said: ‘The Canadian Coast Guard offers our sincere condolences to the family and friends of the crew of the Titan for their tragic loss.
‘Search and rescue operations have concluded.’
Now authorities from the US and Canada have begun the process of investigating the cause of the Titan’s fatal implosion.
The US Coast Guard said on Friday that a formal inquiry has not yet been launched, because maritime agencies are still busy searching the area where the vessel was destroyed.
Debris was located about 12,500 feet underwater, several hundred feet away from the Titanic wreckage it was on its way to explore.

The US Coast Guard led the initial search and rescue mission, which was a massive international effort that likely cost millions of dollars.
The investigation into the cause of the disaster, and any attempt to recover wreckage from the ocean floor, will likely be difficult and painstaking.
‘This is an incredibly unforgiving environment down there on the seafloor,’ said Rear Adm. John Mauger, of the Coast Guard First District.
Meanwhile, Canada’s TSB said a team of investigators had been deployed to St John’s to ‘gather information, conduct interviews and assess the occurrence’.
In a short statement confirming the investigation, the safety body said: ‘The TSB is launching an investigation into the fatal occurrence involving the Canadian-flagged vessel Polar Prince and the privately operated submersible Titan.
‘In accordance with the Canadian Transportation Accident Investigation and Safety Board Act and international agreements, the TSB… will conduct a safety investigation regarding the circumstances of this operation conducted by the Canadian-flagged vessel Polar Prince.
‘A team of TSB investigators is travelling to St John’s, Newfoundland and Labrador to gather information, conduct interviews and assess the occurrence.
‘In the coming days, we will co-ordinate our activities with other agencies involved.’
The TSB said it will not determine civil or criminal liability in the disaster and conducts investigations for ‘the advancement of transportation safety’.
It was not entirely clear who would have the authority to lead the disaster investigation, which is bound to be complex and involves several countries.
The Titan submersible was registered in the Bahamas, but OceanGate, the company that owned and operated the craft, is based in the US.
OceanGate was headquartered in Everett, Washington, but appears to have shuttered operations after the Titan was confirmed lost with the company’s CEO aboard.
Meanwhile, the Titan’s mother ship, the Polar Prince, is flagged in Canada, and those killed were citizens of the UK, Pakistan, France, and the US.
