Update on Mares Abyss 22 and Atomic SS1 Issues
On January 9, NDCSB Chair Ray Boland sent a safety bulletin to all divers describing recent issues with SEP-issued Mares and Atomic SS1 regulators. The safety bulletin required all UDSs to review the issues and NDCSB-provided procedures and reporting guidelines with unit divers by February 9 and/or during the annual unit reviews. Since then, Line Office Diving Officers have confirmed that active units have reviewed the information with their divers.
The NOAA Diving Program has been in touch with Mares and Atomic to remediate the issues. After extensive research, testing, and communication with the manufacturers, the NDCSB has determined:
- Atomic SS1 inflation cap problems stem from damage to the threads due to over-torqueing.
- The NOAA Diving Center will be acquiring special tools to ensure that this does not occur again. NDC has purchased brand new caps and will be replacing the caps of every SS1 regulator as they come in for service.
- The Mares Abyss 22 demand lever issues are harder to pin point but, after close examination by NDC, the Navy Experimental Diving Unit, and Mares engineers, failure factors may include a bend in the lever that prevents proper contact with the nut and washer and/or an incorrect placement of nut and washer over the lever.
- A Mares engineer in Italy is currently studying the issue and working on a potential new demand lever design.
- The Mares General Manager is scheduling a technician to visit Seattle to observe NDC technicians conducting maintenance on the regulators to ensure that maintenance is conducted according to Mares standards.
- The NDCSB is closely monitoring the results of these actions to decide how to proceed in resolving this problem.
In the meantime, all divers should continue to follow NDCSB procedures for these issues and report as soon as possible any adverse findings to NDC. You can read the safety bulletin for the Atomic SS1 here, and the safety bulletin for the Mares Abyss 22 here. Any questions should be directed to your UDS or LODO.
Delays in Dive Management System (DMS) Updates
in March The little elves that work behind the scenes to assist divers with the DMS and other NDC issues have decided to take a well-deserved break. This means that during the month of March, divers will not be able to obtain assistance through the firstname.lastname@example.org e-mail account. E-mails sent there will be attended to in April in the order in which they were received. If you need immediate assistance with a DMS issue, please contact your UDS or LODO.
NOAA Dive Log Update
The new NOAA Dive Log, which will be replacing the NOAA Dive Management System (NDMS) and will function on all internet browsers, is targeted to release by May. The focus of this release is to maintain current functionality with few updates. However, some noticeable improvements will include: An expanded section for diving certifications and Special Task Endorsements, and greater access for UDSs.
NDCSB Annual Meeting
The NDCSB has rescheduled its Annual Meeting to April 9-13 in Key West, Florida. The meeting was moved from a prior date in February. The new date will allow for planning and communication with units regarding agenda topics. If you have a suggestion for the meeting agenda, please send it to your UDS. UDSs should forward the topics to their LODOs as soon as possible.
Rear Admiral Tim Gallaudet’s visit to NDC
On January 24, Rear Admiral Tim Gallaudet, Ph.D., U.S.N. Ret. visited the NOAA Diving Center to meet with leadership, see the Seattle training facility, and discuss NDC’s mission. Dr. Gallaudet is the current Assistant Secretary of Commerce for Oceans and Atmosphere and, during his visit, he expressed his enthusiasm and support for the NOAA Diving Program. He and his wife Caren are active recreational divers and have recently completed training through the NOAA Diving Program to become NOAA Observer Divers. They plan to exercise their observer diver status at many of the National Marine Sanctuaries!
Refurbished containerized Hyperbaric Chamber at IRC
The temporary closing of the sole hyperbaric chamber available in Hawaii at Kuakini Medical Center in Honolulu prompted the NOAA Diving Program to temporarily move NOAA Ship Hi’ialakai’s hyperbaric chamber to the NOAA Inouye Regional Center (IRC) in order to support NOAA divers. Since then, the Hi’ialakai chamber has been returned to the ship and the IRC has received the containerized hyperbaric chamber which was refurbished by NDC and which was shipped to IRC in February. This new chamber will allow NOAA operations to continue regardless of local commercial hyperbaric chamber availability and, in addition, will expand the potential for NOAA hyperbaric chamber training available in Hawaii. NOAA Divers and Diving Medical Technicians Stephen Matadobra and Kerry Reardon will assist in setting up the new IRC chamber.
The use of CCRs and technical diving continues to expand at NOAA. The National Marine Fisheries Service’s units in Southern California have trained two CCR divers to support research on endangered abalone species. The Papahānaumokuākea Marine National Monument divers, who have been using CCRs for many years, are now crossing over from using the Megalodon rebreathers with which NDP started the rebreather program, to the Poseidon Se7en rebreathers recently approved for use by the NDCSB. These new rebreathers will allow the divers to conduct deep dives with a lighter and more agile rig.
In addition, various units are using the new “tech lite” decompression procedures that were outlined for the first time in the NOAA Diving Standards and Safety Manual released in April 2017. The procedures allow divers to conduct decompression dives on open circuit SCUBA gear without mission-specific pre-approval by the NDCSB when conducting dives no deeper than 150 feet. Units currently taking advantage of this program include Thunder Bay National Marine Sanctuary, Monitor National Marine Sanctuary, and Papahānaumokuākea Marine National Monument.
NDC completed the winter NOAA Diver and Divemaster classes in Key West, Florida with 18 NOAA Divers and 11 Divemasters graduating. This year, NDC also offered a Visual Cylinder Inspection class in January and a Tethered Communications class in February, both also in Key West. Congratulations to all the students that completed their training!
NDC is now gearing up for these upcoming classes:
- Field Trainer: March 12-16 in Seattle, WA
- NOAA Diver: May 7-25 in Seattle, WA
- NOAA Divemaster: May 14-25 in Seattle, WA
- Tethered Communications: June 4-8 at Thunder Bay National Marine Sanctuary
In addition, NDC instructors will be supporting the Reef Assessment and Monitoring Program (RAMP) mission aboard NOAA Ship Hi’ialakai, working as Divemasters and hyperbaric Chamber Supervisors from March 15-June 20, 2018.
NDP Featured by NOAA
A photograph from last year’s RAMP mission was featured as one of NOAA’s “Postcards from the Field”. It was great to see the NOAA Diving Program featured in a NOAA outreach e-mail. NDP was able to get this mission featured thanks to Andrew Gray, who generously shared his photographs last year. NDP posted one of his images on the NDP website, where NOAA personnel picked it out as this month’s feature! So, please keep sending in your photographs from the field – NDP needs to show the world the variety of diving and work that takes place in NOAA!
Next NDCSB Meeting
The next NDCSB meeting is scheduled for March 15, 2018. If you are interested in listening to the meeting please contact Ray.Boland@noaa.gov for connection information.
A snapshot from the Field
Ship divers do a lot of hard, unsung diving, including routine and emergency hull maintenance dives. NDP recognizes their hard work which saves NOAA significant amounts of money and time. In this photo, ENS Nicole Chappelle and ST Shane Mallory prepare for a hull maintenance dive on NOAA Ship Hi’ialakai.
