ORCA CLASS PCT's

INTRO
For nearly 50 years, naval personnel were trained on vessels known as YAG's. They provided an invaluable and relatively inexpensive at-sea training for junior naval officers, boatswains, reserve personnel and Sea Cadets.  By the year 2000, a total of 1830 personnel had been deployed on the YAGs for a total of 585 days and steamed over 25,000 nautical miles in support of training.

These wooden-hulled vessels had become prohibitively expensive to maintain, hence replacement became the only option.  The lack of current technology, proper environmental systems, poor habitability and inadequate workspaces did not meet the Navy’s requirements, and reflected poorly on the Canadian Forces.

Replacement of the YAG fleet began in July 2001 when the project was formally identified.  Following a thorough analysis of replacement options, it was decided that purchasing a proven commercial design would significantly reduce the risk to the Crown.  In October 2001, the project issued a Letter of Interest to industry seeking responses from companies who had a proven capability in the construction of vessels of similar size and complexity within the last ten years.  Five companies responded to the Letter of Interest and a request for proposals was subsequently issued in December 2003.  The competition closed in April 2004, and the submissions were evaluated against the mandatory requirements.

The new vessels, designated the ORCA class training vessels will provide an excellent means for both the Regular Force and Reserve officers to hone their bridgemanship and navigation skills.  It will have significant advanced training capabilities, closely simulating the performance and conditions experienced on the major warships. The vessels will have a twin shaft configuration to provide excellent shiphandling characteristics and be able to conduct transits at much higher speeds. The contract was awarded to Victoria Shipyards and the first vessel, PCT55 , began taking shape.

As sailor's cheered and waved their hats, Orca was officially accepted into the Canadian Navy during a ceremony on Nov. 17, 2006. It was to be the first of eight new Patrol Craft Training (PCT) vessels, Orca  features a bridge with navigation electronics updated from the previous Yard Auxiliary General (YAG) 300 series vessels including a global positioning system and improved accommodations. Crew will be housed in double cabins, while cabins of between four and six bunks will house trainees. This vessel reflects the rest of the fleet much more than the YAG's did and is several generations advanced from what the navy had been using for training vessels.

Neil Bell, who toured an Ocra, observed a few of the advanced features found in these vessels. "The helmsman’s position has a chair and a wheel and throttles rather than the combi-levers of the MCDVs as well as two computer screens that can pull up any of numerous “pages” of information regarding propulsion, electricity, tank capacity, etc.  The switchboard automatically adds or takes off line generators according to the electrical load. A screen in the CO's cabin allows him/her to access any information that is presented to the bridge."
Most importantly,  the ORCA class will allow the freeing of the HALIFAX frigates and KINGSTON defence vessels from cadet training duties. As a result, there will be less of a backlog created by the wait for one of those larger vessels to be freed up from regular duties for training. Furthermore, not having to employ large vessels like the 240-crew HALIFAX for mere cadet training duties will be highly economical to the military.

The ships, built by Victoria Shipyards Vancouver, replace the 50-year-old wooden hulled YAG training vessels. Malcolm Barker, general manager of Victoria Shipyards Limited handed over Orca 55 to Cmdre David Gagliardi, Deputy Commander Canada Command, representing the Chief of Maritime Staff at the ceremony on ''A" Jetty, Esquimalt, BC.

"Today, we usher in a new era in navigation and seamanship training for the Canadian Navy. Designated "Patrol Craft Training", the Orca class ships represent a quantum leap into the future of the Canadian Navy replicating the capabilities found in the Navigation and Bridge Simulator at the Naval Officer Training Centre and on the bridge of the Halifax and Kingston class ships as well as the navy's future ships. Sailors will now train in an environment that emulates the ships they will ultimately serve in," said Cmdre Gagliardi.

After Barker signed over Orca to Cmdre Gagliardi, representatives from the Naval Officer Training Centre (NOTC), the Naval Tender  Section and the Royal Canadian Sea Cadets unveiled the kisbee ring at the event. LCdr James Brown, senior chaplain of Canadian Fleet Pacific blessed the ship and then it was time for Orca's future sailors to board and ceremonially man the ship for the first time. Teenage cadets stood next to naval officers on the deck as they waved their hats and shouted, "three cheers for Orca, hip, hip, hooray."

The ORCA class vessels are not in commission  with the RCN therefore it would be incorrect to use the prefix "HMCS" in reference to any of the vessels in the ORCA class.

The remaining Orca class ships will be delivered in coming months and are named PCT 55 Orca, PCT 56 Raven, PCT 57 Caribou, PCT 58 Renard, PCT 59 Wolf, and PCT 60 Grizzly, plus the two newly added vessels PCT 61 Cougar and PCT 62 Moose. "The names of each of the eight ships remind us of the original sailors on the Pacific coast of North America, the Coast Salish First Nations people," said Cmdre Gagliardi. The names of six of the vessels were names also given to the "armed yachts" the Government  acquired in the early years of the Second World War, he added.

Orca class is rather broad in the beam due to its training role. Accommodation was a major factor – three crew cabins (for the crew of four) and three large student cabins (for 16 trainees) were required. Duplicate training stations, etc. also imposed additional space and weight requirements. This limits the usefulness of the Orca as a patrol boat.

 Although the boats were designed with the Junior Officer Training requirement in mind, they may also provide a secondary inshore patrol capability on the West Coast. All the boats will be based at CFB Esquimalt in British Columbia.

On Thursday November 27, 2008 ship horns blared, a red fireboat spurted fountains of water, and cameras flashed to mark the delivery of Moose, the last of the eight ORCA class training vessels built by Victoria Shipyards. Under bright white tents, 250 shipyard workers were treated to a catered lunch to celebrate their work on the Orca-class vessels. All the vessels were built for $86 million with the last one delivered exactly four years to the day since the contract was signed -- and 14 months early, to boot.

orca_sart.jpg SART by Kannad.  SART (Search and Rescue Transponder) is a 9 GHz receiver/transmitter. On receiving a pulse from any standard 9 GHz X-band radar, the SART immediately transmits a signal which clearly identifies the survival craft on the radar screen.  The SART code displayed on the radar screen is a series of dots extending radially outwards from the location of the transponder. The series of dots represents a range of approximately 10 nautical miles. This indication is an internationally accepted signal for Search And Rescue operations. The device pictured in the photo is intended for use in a life raft. (Image courtesy Martec)

orca_s1210_epirb_s.jpg EPIRB -  Model S1210 . The S1210 is an Emergency Position Indicating Radio Beacon (EPIRB) and is a vital safety aid for all vessels. Once activated, the SS1210 will  send an encoded distress signal, indicating the location of the emergency and the EPIRB's unique ID, to the nearest search and rescue center.

The EPIRB's ID number is kept on file by the National Oceanic and Atmospheric Association (NOAA) in the US and the National Search and Rescue Secretariat (NSS) in Canada. When a 1210 is purchased,  there is a registration card that must be filled out and sent to NOAA in the US or NSS in Canada. This ID number tells the search and rescue centre who owns the vessel, the size and name of the vessel, the next of kin, the home address and phone number of the EPIRB owner. 

The device uses a  Xenon light strobe for visual identification, a 121.5 MHz (VHF distress) local homing radio signal and a  406.028 MHz satellite transmitter. (Photo courtesy Rapid Response Marine) 

orca_zenetil_vsp_s.jpg
Batteryless Telephone - Zenitel Model VSP. It  is designed as replacement of the traditional sound powered telephone. Cranking the phone charges a capacitor-battery which can provide up to 20 minutes of talk time before the unit needs re-cranking.  Optionally, the system can also be operated from a 24 VDC external power source to eliminate cranking. By use of a dynamic microphone and a  "receiver-insert" , a sound level four times louder than a traditional Sound Powered Telephone can be achieved. A PDF file explaining the telephone system diagram can be found here.   (Images and courtesy Zenitel  Group)

Differential Global Positioning Systems (DGPS)  is a way of collecting GPS data with increased accuracy. It involves using a radio beacon installed on a surveyed, known point  to help resolve the location of a roving receiver. It does this by correcting the error of all visible satellites that are sending data to a conventional GPS unit.

NOTES:

[1] According to Canadian American Strategic Review, "for a training role, the Orcas will be fitted with the Raytheon Pathfinder NCS 18 X-band navigation radar (illustrated) and the MX420 DGPS which makes use of four Canadian Coast Guard DGPS stations on the west coast and a Anschütz Pelorus (dumb) compass". It is believed that the 1810 would be fitted if the Orca is assigned to patrol vessel duties. Can anyone confirm this?

[2] This is listed as a Cellular Telephone on other web sites. It is correctly shown here as a Fixed Wireless Terminal with the correct spelling of the company name.

[3] The Raytheon Model RM80 AS could not be located on the web. Raytheon's current product line (2006) illustrates model RM808AIS so it is believed there may be an error in the equipment manifest. Instead, the Model RM808 is shown.

[4] The company name has been corrected. IT should read as "Anschütz". This is a division of Raytheon.

[5] The full company name is Taiyo Musen but they market their products under the shortened "Taiyo" brand.

[6] No such model as 110-233 could be located on the web. The only Raytheon gyrocompass located was the Standard 22 product, so it is assumed that this is the one being referenced in the equipment manifest.

[7] Nothing was found on the web when searching for "Anschütz Pelorus" or in combination with the indicated model number. Is there any source for an image of the device?
