Experience is our way of setting the bar higher
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 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 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.

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.

Marine Transport Lines Inc. requested Divers to support the TURBO activation of USNS CAPE EDMONT (AKR-5069). The CAPE EDMONT is part of the National Defense Reserve Fleet in Charleston, SC and must periodically “reactivate” to access the crew and ship's readiness. Seaward Divers mobilized to Charleston, SC and completed hull cleaning utilizing Seawards SCAMP multi-brush cleaning platform. The Divers also completed the propeller polish, cleaning of the shaft, rudder, sea-chests, bilge keels, and the bow and stern thrusters on the 682’ ship within 24 hours of diving. For all the hard work and long days, a job well done for the Divers and Crew of Seaward Mobile Unit One.

Seaward Marine Services completed underwater hull cleaning and inspection on the USS CONSTITUTION (IX-21) on April 7, 2015 in support of an upcoming Dry-Dock period in May 2015. USS CONSTITUTION is one of six Frigates authorized for construction in 1794, was named by President George Washington after our U.S. Constitution and is the oldest fully commissioned U.S. Navy ship. Seaward Marine Divers completed a pre-clean assessment, the hull cleaning and post-clean documentation report within sixteen working hours. The Divers Hull Inspection Data report with photos was delivered to the Naval History and Heritage Command Detachment and the NAVSEA Director of Ocean Engineering Supervisor of Salvage and Diving on site Representative.
As recognition to Seaward’s involvement in the preparation of the dry-docking Seaward’s Divers were given the opportunity to sign a sheet of the copper cladding that will be used to replace sheeting installed during the CONSTITUTION’s previous docking in 1992.

In September, Seaward Marine NDT Division completed its eleventh Lamp Ray hull survey within a five-month period ending an intense but rewarding effort by the division’s staff. A few of these surveys can take as long as two weeks depending on the size of the unit being gauged, but all hulls were completed on time and on approved budget including a four ship run in August that began with the USNS CAPE RACE in Portsmouth VA and ended with three ships in San Diego CA. The list included seven U.S. Navy warships, two Naval Reserve ships and the Display Ship BARRY.
After finishing three ships in May and early June Crowley Maritime requested a underwater hull cleaning, ABS inspection and hull survey services for the Ready Reserve Ship S.S. WRIGHT home ported in Baltimore M.D. The Lamp Ray Crew transited back to Norfolk to complete a U.S. Navy asset then traveled to Washington D.C. to complete the Display Ship BARRY at the Washington Navy Yard (see July 8 posting).
The NDT Division is scheduled to complete two more Lamp Ray hull surveys before the end of this year.
