Experience is our way of setting the bar higher
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.

Seaward Marine Services Mobile Unit 4 got the call for an immediate need to clean the underwater hull of MV Frisia Bonn for Independent Container Lines of Wilmington, NC. Our customer said the ship was experiencing 20% “slippage” referring to efficiency lost in the thrust of the propeller. In the case of MV Frisia Bonn this was due to moderate marine growth on the hull and propeller causing more shaft turns required to make desired speed which dramatically increases the fuel consumption rate.
Independent Container Lines authorized the work on Wednesday 10/1 in the afternoon, the crew mobilized out of Norfolk VA on Thursday, and met the ship at the terminal 0700 on Friday 10/3 to begin dive operations. Despite diving in a hostile environment with a very swift non-stop current Seaward Mobile 4 crew pushed through continuously for 20 hours to get the hull cleaning complete and the ship underway as soon as possible. “Thanks very much for your quick response and hard work; I understand the conditions, at times, were less than favorable” said Rob Frazier Sr. Director US Ports & Warehouse Operations Independent Container Line.

Seaward Marine Services completed underwater inspections and cleaning on the USS NAUTILUS (SSN-571), the first nuclear powered submarine was launched in 1954 and the first ship to reach the geographic North Pole- 90° north had an extensive and pioneering role in the groundbreaking uses of nuclear power. NAUTILUS was decommissioned on March 3, 1980 after a 25-year career. In April of 1986, NAUTILUS joined the Submarine Force Museum in Groton CT. as the Historic Ship NAUTILUS.
Seaward Divers used the multi-bush machine SCAMP to clean the underwater hull followed by Divers with single brush machines cleaning smaller areas then inspecting and photo documenting all underwater appendages and the overall condition of the hull.

Divers replaced a four-foot Impress Current Cathodic Protection Anode on a Navy Ship in accordance with NAVSEA UWSHM Chap-19 “Cathodic Protection Systems”. As a qualified contractor for the U.S. Navy, Seaward Marine Services is required to meet stringent NAVSEA Director of Ocean Engineering Supervisor of Salvage and Diving requirements. The anode was found to be inactive and damaged during August 13 inspections and scheduled to be replaced by the SEA 00C representative, Seaward divers started repairs August 20 and completing repairs the following day. After the initial installation and operational test by Ships Force, divers used HYCOTE 461 to replace the insulating dielectric shielding that was removed when replacing the anode.
