Underwater Hull Cleanings Completed on Two JHSVs

Seaward’s Mobile Diving Unit 3 completed underwater hull cleanings on two Joint High Speed Vessels (JHSV’s). Mobile-3 performed a full underwater hull cleaning on the USNS Trenton (JHSV-5), latest ship of this class and a partial cleaning and inspection of the USNS Choctaw County (JHSV-2) in a three week period of time. Cleaning of this class is made more challenging due to the foul release coating and the detailed cleaning needed on the water jet assemblies and impellers for the two underwater hulls. All cleanings were accomplished using NAVSEA 00C5 approved procedures.  As always the Seaward divers rose to the challenge.

Seaward Marine Mobile Diving Crew Cleans Their Way Through the Northeast

Seaward Mobile Diving unit 4 mobilized on August 16, 2015 for an extended three city road trip which covered 1620 miles. During the three week excursion four vessels were cleaned and two were certified with an American Bureau of Shipping (ABS) Underwater Inspection In Lieu of Dry-Docking (UWILD). The TS State of Maine received a full underwater hull cleaning, ABS UWILD inspection, a Lamp Ray Hull Survey, and a Data Scan. The crew also cleaned and inspected the Maine Maritime Academy (MMA) Barge Oyster Bay. With the work in Castine, ME completed Mobile 4 demobilized and moved two hours south to Rockland ME for a full underwater hull cleaning and ABS UWILD inspection of the Giant Cement Companies Barge MBT-35. Upon completion of Barge MBT-35 the crew packed up and headed 350 miles farther south to Groton CT, the Submarine Capital of the World to provide services to the submarine community.

Matt O’Donnell, Port Engineer/Marine Surveyor with the United States Department of Transportation - Maritime Administration stated, “Tom, your crew did an excellent job. It was a pleasure working with such professionals.”

Capt. Dana Willis, Marine Operations Manager for the Maine Maritime Academy writes “Tom, Thanks for putting this whole operation together for us on short notice, and your entire crew was helpful and easy to work with through the project.”

Seaward Marine Services would like to commend the entire Mobile 4 dive crew and the Lamp Ray team for their professionalism and willingness to go where the work takes them on short notice. A job well done!

Seaward Divers Complete Underwater Repair of Six ICCP Anodes on Navy Ship

Underwater Repairs of the Cathodic Protection system on a Navy ship were completed in August, with the waterborne replacement of six ICCP system anodes by Seaward’s Mobile Diving Crew 2 in Norfolk VA.  A Cathodic Protection system helps to slow and combat the electrochemical effects of corrosion to a ships underwater hull, a condition which is always present due to the variations in the chemistry of metal, both within the hull, and between dissimilar metals.

The repair work included not only replacing the external anodes, fasteners, and dielectric shielding material around the anodes, but also the components on the vessels interior. The faring material, which is traditionally a two part capastic material installed as a dielectric shield, could not be used in an underwater environment so Seaward Divers used the U.S. Navy NAVSEA approved Hycote 461 faring compound on the areas where the capastic had to be removed.  Hycote 461 fairing compound is the preferred method when installing CP anodes in-water.

 By doing this work waterborne a significant savings was afforded the Navy.  Additionally, Seaward personnel completed the project three days ahead of schedule and 18% under budget, giving our customer a substantial savings. The Project manager and Mobile 2’s crew showed great professionalism, and did an exceptional job ensuring the ships underwater hull and appendages were protected once again against all forms of corrosion.

Great Job!

Seaward Marine Cleans JPO Aquarius

Seaward Marine Services Mobile Unit 4 transited to Wilmington North Carolina during the July 4 weekend to clean the underwater hull of JPO Aquarius.  The crew mobilized the evening of July 2nd and started work the morning of July 3rd.  The dive crew worked through a hostile environment with a very swift non-stop current continuously for 18 hours to get the hull cleaning complete and the ship underway as soon as possible in the early morning hours of July 4.  As the dive crew was pulling away from the pier so was JPO Aquarius on to its next destination. We appreciate the dedication and commitment our divers put in to complete a task when asked, especially on Independence weekend.

Seaward Marine Divers Clean and Survey EX-USS Midway

As part of Seaward Marine Services, Inc.'s continuing contract with the MIDWAY Museum in San Diego, CA, divers completed an underwater hull cleaning using SCAMP, coating of bare metal areas on the underwater hull using HYCOTE underwater coatings, and a hull potential survey on the EX-USS MIDWAY (CV-41).  Divers then completed an inspection and documented the hull conditions for future planned maintenance.  This most recent maintenance period was completed in June 2015.

The full hull cleaning using Seaward's SCAMP multi-brush platform was performed in accordance with NAVSEA’s Naval Ships’ Technical Manual Chapter 081, Hull Cleaning Guidelines.  Afterward, bare metal areas were identified and the dive crew applied approximately 250 sq. ft. of HYCOTE underwater coating to the underwater hull, running gear, and seachest blank box attachment areas which required repair.  HYCOTE is a superior underwater coating approved by the U.S. NAVY for the preservation of bare metal areas in high humidity and underwater environments.  The underwater hull potential survey was done at the completion of the underwater coating of bare metal areas, and utilizes a handheld silver-chloride probe measures hull potential values or the ability of the underwater hull to protect itself from corrosion.  The survey documented an increase in hull potential values in the mid-ship and bow areas of the hull. This reporting allows the ship’s engineers to monitor and track both current and historical data for hull preservation.

Seaward Marine Services, Inc. is proud to be a part of the ongoing preservation program for EX-USS MIDWAY which started in January of 2010.

Seaward Divers Lend Their Cleaning Skills to Breezy Point Triathlon

Seaward Marine Services Divers took some time Friday evening on May 29th to prepare the Naval Air sea plane ramp for the 24th annual Breezy Point Triathlon at Naval Station Norfolk.  The event is the only triathlon in the area and is a popular race for first time and beginner triathletes because of the manageable distances.  Seaward Divers arrived Friday prior to start of the race to clean the sea plane ramp of any marine growth and debris that has accumulated on the ramp giving the athletes a safe area to enter and exit the swimming portion of the event.

Seaward employees wish all Triathletes good luck in completing the 2015 Breezy Point Triathlon.

Seaward Marine Divers Complete Three JHSV Class Cleanings for MSC

Seaward Marine divers completed hull cleaning on three JHSV class ships in Norfolk, VA, Cape Canaveral, FL, and Honolulu, HI.  Divers completed full hull cleanings on the FALL RIVER and CHOCTAW Co while completing cleaning of the water jet assembly, impellers, and sea chests on the MILLINOCKET.  All three USNS ships were completed within the contracted time estimate, which also included additional Hycote work on MILLINOCKET’s leading edges of the keel and ride control surfaces, which were mechanically prepped and the underwater paint Hycote 461 was applied to these high abrasion surfaces.

Seaward Marine Services NDT Division Completes over 100 Hull Surveys using Lamp Ray® ROV

As of April 2015, the Seaward Marine Services, Inc. NDT Division has now completed more than 100 hull surveys using the Lamp Ray® ROV, recently including three LPD class ships and two USNS ships in Norfolk, and a CG in San Diego.

LAMP RAY® is a robotic scanning system that gives a complete picture of the ships underwater hull condition including hull plate thickness, paint dry film thickness, cathodic hull potential, and visual inspection.  This is accomplished using accepted and approved techniques and practices by the U.S. Navy, U.S. Coast Guard, and classification societies.  The ROV “is a underwater NDT laboratory” whose location is tracked using a high precision acoustic tracking system that records this data in ships coordinates with high precision (±15cm = ±6in),.all data is time stamped which permits post-survey verification and validation of data.  All of this allows NDT technicians to process and review this data and generate a survey report in an html format which uses standard internet browser to view the report.  This allows for an easy to read report thus giving the ships manager the ability to identify potential problems that can be planned for and addressed.
