2023 Titan submersible incident

On 18 June 2023, the Titan, a submersible operated by OceanGate Expeditions, went missing in the North Atlantic Ocean off the coast of Newfoundland in Canada. The submersible, designed to accommodate five people, was carrying an expedition of tourists to view the wreckage of RMS Titanic.^[1] The breathable air supply is expected to expire on 22 June 2023 at approximately 04:00 NDT (UTC−02:30).^[2]

Titanic

RMS Titanic was a British ocean liner that sank in the North Atlantic on 15 April 1912 after colliding with an iceberg. In 1985, its wreckage was discovered on the ocean floor around 400 nautical miles (740 km) from the coast of Newfoundland.^[3] The wreck lies at a depth of about 3,800 metres (12,000 feet; 2,100 fathoms).

Titan

Titan is a five-person vessel constructed of carbon fiber and titanium.^[4] Its steering controls consists of a Logitech G F710 (a wireless PC game controller) with modified joysticks.^[5][6][7] The vessel is operated by OceanGate, Inc. and is designed to dive as deep as 4,000 m (13,000 ft) "for site survey and inspection, research and data collection, film and media production, and deep sea testing of hardware and software".^[4] According to OceanGate, it contains "proprietary Real Time Hull Health Monitoring (RTM) systems ... that [assess] the integrity of the hull throughout every dive".^[4] The vessel has life support to support five crew members for 96 hours.^[4] Prior to losing contact, internet access was provided from SpaceX's satellite system, Starlink.^[8][9]

Expeditions

Typically, each dive has "a pilot, three paying guests, and what the company calls a content expert" on board.^[1] Once these people are inside the submarine, the hatch is bolted shut and must be reopened from the outside.^[10] The descent from the surface to the Titanic typically takes three hours,^[11] with the full dive taking approximately eight hours.^[1] Throughout the journey, the submersible is expected to communicate with the above-water crew every 15 minutes.^[3]

Customers who travel to the Titanic with OceanGate, referred to as "mission specialists" by the company,^[12] spend US$250,000 to be involved in the eight-day expedition.^[1][13]

Technology writer/reporter David Pogue, who completed the expedition in 2022 as part of a CBS News Sunday Morning feature^[14], stated that all passengers who enter the Titan sign a waiver confirming their knowledge that it is an "experimental" vessel "that has not been approved or certified by any regulatory body, and could result in physical injury, disability, emotional trauma or death".^[15] Mike Reiss, who has also completed the expedition, noted that the waiver "mention[s] death three times on page one".^[16]

OceanGate intended to conduct multiple expeditions to the Titanic in 2023, but because of poor weather in Newfoundland, the company has only launched a single expedition so far in 2023.^[1][11]

Controversy

In 2018, the Marine Technology Society wrote a letter to OceanGate CEO Stockton Rush expressing "unanimous concern regarding the development of 'TITAN' and the planned Titanic Expedition", indicating that the "current experimental approach ... could result in negative outcomes (from minor to catastrophic) that would have serious consequences for everyone in the industry".^[17]

Also in 2018, a former OceanGate submersible pilot and its director of marine operations filed a lawsuit claiming he had been wrongfully terminated for bringing up concerns about the Titan's ability to safely operate at extreme depths, specifically stating the vessel was only certified to reach a depth of 1,300 meters, a third of the depth required to reach the Titanic.^[18] OceanGate, which was suing him for allegedly disclosing confidential information, settled the lawsuit a few months later.^[18]

In 2022, during an expedition to the Titanic, the Titan lost communication with the above-water ship, as reported by David Pogue, who was onboard the mission.^[19] Pogue's report for CBS Sunday Morning, which questioned Titan's safety, later went viral on social media.^[20] It included allegations that the steering for the submarine was controlled by a $30 Logitech F710 game controller.^[21]

 

People aboard

• Shahzada Dawood, Pakistani businessman (of the Dawood Hercules Corporation) and a trustee at the SETI Institute.^[23]
• Suleman Dawood, son of Shahzada Dawood.^[15]
• Hamish Harding, British businessman, aviator, and space tourist.^[13]
• Paul-Henri Nargeolet, former French Navy commander, diver, submersible pilot, member of the French Institute for Research and Exploitation of the Sea (IFREMER),^[11][13] and director of underwater research for E/M Group and RMS Titanic, Inc.,^[24] which owns salvage rights to the wreckage site.^[25] Nargeolet has led several expeditions to the wreck, supervised the recovery of thousands of artifacts, and is "widely considered the leading authority on the wreck site" according to The Guardian.^[24]
• Stockton Rush, OceanGate, Inc. chief executive and founder.^[26

今までは、有線式のゲームパッド（ELECOM JC-U3613MBK）を
使っていましたが、価格が安かった（1900円くらい）ので、
使い勝手等どんなものかと思い、ちょっと試しに ワイヤレス
ゲームパッド F710 を買ってみました。(^_^ゞ
一応、Xbox 360 コントローラーのドライバーをインストール
してみましたが、当方の環境（OS: Windows 10）では、
パソコンの電源オフ後、再び電源を入れた時に、
ドライバーを見失うみたいです。(^_^;)　
｛パソコンをリセットした時もドライバーを見失う。｝
したがって、当方の場合、ワイヤレス ゲームパッド F710 を
下記のような感じ（手順）で使っています。(^_^ゞ
　　　　
　《 ワイヤレス ゲームパッドの利用手順 》
　（１）普段、F710 を使わない時には、
　　　　（例：パソコンが電源オフ状態の時）
　　　　ゲームパッドから電池を抜いておき、かつ、
　　　　レシーバーをUSBコネクタから抜いておく。
　　　　 ⇒ たとえば、レシーバーは電池カバーの中
　　　　　　（電池ボックスの下方）に収納しておく。
　（２）パソコンの電源を入れる。
　（３）パソコンが起動したら、ワイヤレス ゲームパッド
　　　　「F710 接続ユーティリティ」プログラムを実行する。
　　　　　 ⇒ [続行] ボタンをクリックする。
　（４）USBコネクタにレシーバーをさす。
　（５）30秒以内に ゲームパッド F710 に電池を入れる。
　（６）その後（ゲームなどが終わったら）、パソコンの
　　　　電源を切ったら、レシーバーをUSBコネクタから
　　　　抜き、ゲームパッドから電池を抜いておく。
　　　　
このように、レシーバーの抜き差し、および、電池の
出し入れが苦痛でなければ、F710を使うことができるが、
面倒な人には不向きな ワイヤレス ゲームパッド かと
思われます。(^_^;)
現状では、やっぱり有線式のゲームパッドのほうが

無難（面倒が少ない）かなぁ…と言う感じです。(^_^ゞ

、、、（爆ｗｗｗｗｗｗｗｗｗｗｗ
