SWEPT OVERBOARD

Three dead, five rescued in SA Navy submarine disaster off Kommetjie, Cape Town

The accident came after a weekend of high winds and rough seas and a South African Weather Service warning of damaging waves in Cape Town on Wednesday.

The Department of Defence (DoD) has confirmed the deaths of three mariners on Wednesday in an incident involving the South African Navy submarine SAS ’Manthatisi. The vessel was offshore of Kommetjie in Cape Town when high waves swept seven crew members out to sea. A rescue operation launched just before 3pm saved the lives of five personnel.

SAS ’Manthatisi was en route to Table Bay from Simon’s Town for the South African Navy Festival, scheduled to take place at the V&A Waterfront from 23 to 25 September. According to the DoD, the mariners were in the process of conducting a “vertical transfer” (Vertrep) using an SA Air Force SuperLynx helicopter when they were swept overboard.

style="font-weight: 400;">Vertrep is a method of supplying seaborne vessels by helicopter.

“The Vertrep evolution was immediately cancelled and efforts were launched to recover the members. A surface swimmer was dispatched from the helicopter to assist with the rescue. Unfortunately, the recovery operation was negatively affected by rough sea conditions,” the DoD said late on Wednesday.

“All seven members were recovered, but sadly there were three fatalities, with one senior officer in critical condition. The remaining members, including the surface swimmer, are currently being treated in hospital. The names of the members will be released once the next-of-kin have been informed.”

A weather alert issued by the South African Weather Service warned of “damaging waves” in the City of Cape Town/Cape Point region on Tuesday and Wednesday.

“Difficulty in navigation at sea for small vessels and personal watercraft … are expected [sic]. Localised disruption of small harbours and/or ports could also occur. Small vessels are at risk of taking on water and capsizing in a locality,” the warning stated.

“Be aware of large, unpredictable waves along the coast. Small vessels are advised to seek shelter in harbours, bays or inlets.”

Witnesses of the rescue efforts in Kommetjie told Daily Maverick that the swells off the coast were huge.

The naval accident comes just days after high waves, strong winds and a spring tide caused chaos in coastal areas of the Western and Eastern Cape and KwaZulu-Natal. Seas were rough, and powerful waves swept inland, damaging property and resulting in two deaths.

Joint rescue operation

National Sea Rescue Institute (NSRI) Kommetjie was activated following reports of navy personnel in distress offshore of Slangkop Lighthouse, near Kommetjie, said NSRI spokesperson Craig Lambinon. They were joined by other rescue teams, including the City of Cape Town’s Water Rescue Network, SAPS and SA Navy command.

“Of the seven people that were brought to shore at Kommetjie by NSRI Kommetjie — seven adult males — CPR was conducted on two adult males who sadly were declared deceased on the scene. One adult male was airlifted to hospital by Netcare 911 helicopter. He remains, we believe, in a critical condition. Four adult males were in satisfactory condition and did not require [going to] hospital,” Lambinon said.

Dave Smith, NSRI Kommetjie station commander, reported that one SA Navy officer remained onboard the submarine. She was extricated in the late afternoon, offshore of Hout Bay, in a coordinated operation involving an SA Air Force helicopter, NSRI air-sea rescue swimmers and EMS rescue paramedics.

“Sadly, despite extensive CPR efforts, the female officer was declared deceased. The body of the female was airlifted to the NSRI Hout Bay rescue station. The bodies of the three deceased have been taken into the care of Government Health Forensic Pathology Services,” Smith said.

Lambinon said, “Our thoughts and condolences are with the families who have lost loved ones in this accident, and our thoughts are with everyone affected by this accident.”

In a statement on Wednesday evening, the DA conveyed its “sincerest condolences” to the “families, friends, and colleagues of the mariners who tragically lost their lives” in the incident. DM

Thanks for all the sympathy to the submariners that have lost their lives on serving their country. T stress and put some light on the SA Navy. I have the utmost respect for all the submariners serving in the SA Navy. I am also talking as a parent of one of the submariners that were on the submarine during this disaster. we as parents know when they go out to see and hope to hear from them when they return from see. You don’t know where they are 90% of the time. So, you as a parent can't get in your car and go looking for them. All of them are in the hands of the SA Navy and I as a parent have the utmost respect for the SA Navy. I can only thank the Lord that my daughter is one of the submariners that will be returning home. My heartfelt condolences to the families that have lost one of their children, Farther, brother. I can only imagine what they are going thru. As I have been in the same situation after receiving the message of the disaster. You don’t know what to expect. So if any person want to leave a comment please do so, and I will defend the sailors/submariners of the SA Navy.

As someone who has spent a lot of time at sea one thing that's puzzling to me is how why the submarine appears to have been positioned to take the sea on its beam. A beam sea causes extreme instability in most vessels, but especially a submarine which has no keel and less ballast than a surface vessel. When operating in a heavy sea, vessels typically adopt one of two strategies. The first is to "heave to,” which involves an after quarter and drifting along with the wind. This was clearly impossible given how close the sub was to shore and the wind direction. The second strategy is to take the sea head on by pointing the bow towards the direction of wind and waves. That makes it easier to prevent the vessel from rolling -although on a submarine it would mean that everything forward of the sail would be awash most of the time. Given the severe budget constraints and the doubtful professionalism of the Navy's Junior and mid-level officers, I suspect that the problem boils down to poor seamanship. It's true that naval vessels must practice in all conditions, but if they're not practicing the right approach to the conditions, disasters like this are to be expected.

you got that right!!

It's also basic seamanship practice to have safety harnesses worn properly and hooked on and life jackets at least semi inflated, had this been done this would never have happened

Deepest condolences to the families of the mariners who passed away in this distressing accident at sea. A word of praise to the rescuers for their bravery. May their souls rest.

Sincere condolences to the families of the deceased. A huge shout out to NSRI and the other Cape Town and province supporting rescue services.

The Government should immediately donate R100 million to the NSRI (no strings attached).

The swell wasn't unusually large yesterday, I surfed.

What was needed here is humble-male-common-sense! I was on a frigate many decades ago, and i was present when a senior seaman said to our captain: "Sir, we cannot do that!" We all were fully trained, not tainted by a hidden feeling that we don't deserve to be there, but humble enough to acknowledge dangerous situations. On another trip we sailed to Gough Island, with a helicopter on board, to pick up a sick person on the island, and the pilots refused to use the helicopter to rescue that man, because of the wind, waves and swelling. Not because they were cowards, but because they were well trained, they used common sense and their egos did not get in the way

May the souls of the faithful departed rest in God's peace and rise in His glory. I would like to express my deepest condolences to the families, know that God will get you through this storm, to those still in hospital we pray for a speedy recovery and may God continue to bless you abundantly. To the whole SA Navy kindly note that we as the Nation pray for you as you guys have also lost colleagues and friends.

Sounds like the real heroes are the NSRI, an organisation funded solely by donations and sponsorships. I hope people respond by supporting these amazing volunteers!

Sheer incompetence
