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

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 Cleans MV Frisia Bonn

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 Divers Complete Underwater Hull Cleaning and Inspection of Historic Ship NAUTILUS

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.

Seaward Divers Replace ICCP Anode on Navy Ship

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.

Seaward to give presentation on Underwater Ships Husbandry at Maritime Heritage Conference

Seaward Marine Services is invited to the 10th annual Maritime Heritage Conference to participate in an education session by explaining the benefits of underwater ships husbandry “How Technology can Postpone or Predict Dry-docking”.  Seaward will discuss hull surveys using LampRay® that can document Hull thickness, paint thickness, hull potential, and video document the underwater hull while tracking its position in the water resulting in a comprehensive hull condition assessment with accuracy within +/- 6”.  Maintaining and repairing ships underwater hull will also be discussed including the benefits of hull cleaning, underwater painting, and Impressed Current Cathodic Protection.

The education session will also include opening words from John Elliker of Nauticus and a technical presentation of LampRay by Edwin Slate, engineering consultant of Control Solutions.

Seaward Marine Services Mobilizes Dive Crew to Washington Navy Yard to Inspect Display Ship BARRY

Seaward Marine Services mobilized a dive crew to Washington Navy Yard at the direction of NAVSEA Director of Ocean Engineering, Supervisor of Salvage and Diving (SUPSALV), start hull cleaning and inspections on the Display Ship BARRY DDG-933.  Seaward Marine’s divers started hull cleaning using the SCAMP multi-brush machine on Tuesday July 8th and completed all hull cleaning and visual inspections on July 10th.  Seaward Marine Services NDT division mobilized on July 9th and started underwater hull thickness, hull potential, and paint thickness readings on July 11th 2014 using the Lamp Ray platform, a ROV used to record and track this data.

The LampRay platform uses a high precision acoustic tracing system that allows real time data display and location.  The final report is delivered in a HTML format that can be easily navigated through color coded data presentation for rapid decision making.

The SCAMP multi-brush platform can clean an area approximately 5.5 ft. at 30 ft. per minute. The Display Ship Barry a Forrest-Sherman Class destroyer is 419 ft. long with a beam of 45 ft. took approximately 5.5 hours to clean the flat hull surfaces.

All cleaning and inspections were completed using the requirements that include UWSHM chapter 28, chapter 17, and Navy technical manual Chapter 081 as required by SUPSALV.
