John-Cabot Ship Details and Seafarer Feedback

The urgent search for the 21-foot submersible 'Titan', which vanished on June 18 while on an expedition to explore the wreckage of the RMS 'Titanic', is still underway under the leadership of the Unified Command. The 'Titan', carrying five individuals, lost contact with its support vessel, the 'Polar Prince', approximately 1 hour and 45 minutes into its dive at around 900 nautical miles east of Cape Cod. The submersible was initially launched at 8 a.m. EDT and was expected to resurface at 3 p.m. EDT. By the morning of June 21, the Canadian Coast Guard's multi-functional vessel, 'Joh Cabot', equipped with sonar technology, joined the search effort along with commercial ships like 'Skandi Vinland' and 'Atlantic Merlin'. A Coast Guard C-130 aircraft also reached the area to assist in the search operations. Notably, underwater sounds have been detected, prompting the redirection of remotely operated vehicle (ROV) missions to investigate their source. This crucial data is being shared with the U.S. Navy for further assessment and strategic planning. Additional assets have been mobilized, with the following vessels en route: - Canadian Coast Guard Ship Ann Harvey; - Canadian Coast Guard Ship Terry Fox; - Motor Vessel Horizon Arctic (ROV); - French Research Vessel L’Atalante (ROV); - HMS Glace Bay, which carries a mobile decompression chamber and medical teams; - Air National Guard's C-130 aircraft; - ROV from Magellan. The Unified Command is weighing the capabilities, availability, and logistical considerations of various ROVs already on location, with Magellan set to send one of their ROVs shortly. Furthermore, the U.S. Navy is dispatching experts and a Flyaway Deep Ocean Salvage System (FADOSS), which is engineered for the reliable recovery of substantial underwater objects, including aircraft and small vessels. This combination of expertise and advanced equipment is expected to enhance the operation's effectiveness. Personnel and resources from the U.S. Navy are slated to arrive in St. John’s on the night of June 21. The Coast Guard remains in close collaboration with global partners to ensure that all available resources are utilized efficiently in this critical search operation.

The Canadian Coast Guard is actively overseeing ongoing issues related to the components of its three new offshore fisheries science vessels. These issues have primarily involved the 'Sir John Franklin', 'Capt. Jacques Cartier', and 'John Cabot'. Notable concerns included failures of a propulsion shaft tube and valves crucial for seawater intake, attributed to corrosion, premature wear, and mislabeling. A critical incident occurred when a faulty motor speed switch resulted in a fire aboard the 'Sir John Franklin', prompting a stop-sail order from independent inspectors representing Transport Canada Marine Safety. Fortunately, the malfunctioning controller was identified as an isolated instance. Constructed at Seaspan Shipyard in Vancouver, these vessels, representing a $778 million investment under the National Shipbuilding Strategy, began service between 2019 and 2021. Their primary roles involve fisheries science and monitoring across the Pacific and Atlantic Oceans. The forward and aft propulsion shaft stern tube bearings are necessary for the smooth operation of the propellers. Repairs have been completed on both the 'Sir John Franklin' and 'John Cabot', with the latter, stationed in St. John's, being the newest addition to the fleet. The 'Capt. Jacques Cartier', based in Halifax, is scheduled for a water withdrawal in April for a comprehensive refit, during which its propeller shaft tube bearings will be replaced. The tender for this work is set to close next week, as signs of premature bearing wear have become evident. Additionally, seawater piping and valve replacements have been successfully executed on all three vessels. A report identified multiple potential causes for the issues, including fluid flow rates, dissimilar metals leading to galvanic corrosion, and the aforementioned mislabeling of valves. Upon delivery, the vessels came with a one-year warranty, and at the time of the repairs in January 2022, only the 'John Cabot' remained under warranty for its stern tube bearings. In the fall of 2021, the 'Sir John Franklin' underwent dry dock maintenance for various repairs, including stern tube bearings at a cost of $410,978.53. Although the propulsion variable frequency drives were under an extended warranty, the failure occurred post-warranty expiration. Repairs to the starboard variable frequency drive were made during a subsequent $2.4-million refit. Investigations revealed that the failure was indeed rare and no similar issues were found on the other vessels. Following the completion of the refit in December, the American Bureau of Shipping lifted the stop-sail order, allowing the ship to return to active duty in January.
