- Description
- Shipyards have been ineffective at estimating and bounding the preservation and structural repairs required for external hull welds.� Underestimating structural repairs leads to production and contractor churn, work execution delays, and unexpected costs during maintenance periods. Preservation repairs are determined based on the as-arrived paint condition, which can initially be assessed as small touch-up paint repairs or extensive coating replacements.� Structural repair scope growth can have a gradual impact on an availability, since small increases to predicted scope can often be absorbed without significant impact to schedule.� However, large increases to structural weld repairs can have a significant impact to cost and schedule of an availability. Visual inspections are the basis for scoping the preservation and structural evaluation scope.� These visual inspections require a person to enter the space and is limited by what the inspector can see in a painted, corroded condition.� It is not until the paint and corrosion are removed by abrasive blasting that the inspector can completely and accurately quantify the amount of structural repairs required.� Reliance on visual inspections alone limits the ability to accurately assess current conditions and predict the future scope of work.� NNL is interested in technologies that can measure the degree of metal loss through paint and loose corrosion A new or available technology that can characterize the condition of metal (i.e., metal loss) through paint and loose corrosion is requested for submission.� The standard material is HY-100 base material, using HY-80 weld filler material.� The ideal state for the technology would be for the inspection to be performed inboard of the hull, to support the ship being waterborne.� The intent is to perform the inspection without removing paint or interferences.� Update 3/29/2021: Additional attachment provided with Needs Statement from a shipyard interface.
