Hull Lifecycle ProgrammeIntertanko Annual Meeting Dr. Pierre C. Sames, Head of Strategic Research and Development
Hull condition monitoring Requirements come from flag states and classification • IMO requirements (ESP, PSPC) • IACS requirements cargo owners • CAP surveys, TMSA ship owners • Optimizing hull maintenance Thickness measurements and visual inspections are the tools. Hull Lifecycle Programme
The goals of the GL Hull Lifecycle Programme (HLP) • Life-long access to all information on hull condition • Fast overview and clear communication through 3D visualization • First class support for planning and assessment of hull inspections • Avoid costly repairs through timely maintenance Hull Lifecycle Programme
Thickness Measurements (TM) today • Measurements typically take several days • Approx. same time needed for reporting as for measurement • Highly manual process • Frequent copying of data • Difficult to visualize findings • No electronic assessment support (except Excel tables) Hull Lifecycle Programme
Assessment of thickness measurementswith GL Pegasus Structural Modelling Measurement Preparation GL Strength Assessment Visualisation, Assessment & Report Generation Data Collection TM Company Ship Owner Hull Lifecycle Programme
TM companies work more efficiently Generate printouts for use on board Take the readings and mark locations and order on printouts Create sequence(s) of points in GL Pegasus • measurement values are transferred automatically • locations are only entered once • no redundant data input connect UTM Gauge and download results to GL Pegasus Visualise and print the results... Hull Lifecycle Programme
class renewal class renewal update of model Thickness measurement process is acceleratedwith GL Pegasus The standard process 1-2 weeks measurements up to 4 weeks for final reporting Ship in drydock Ship out of drydock The process with GL Pegasus model creation 1-2 weeks measurements final reporting Ship in drydock Ship out of drydock The target: report finished, before ship leaves dry dock Hull Lifecycle Programme
Visualisation/Assessment of Results • Results can be visualised in both 2D and 3D • Easy identification of hotspots: S: substantial corrosion (yellow) I: substantial corrosion, to be investigated whether locally limited (orange) R: has to be renewed (red) • clear view of inspection results: • avoidmisinterpretationofresults • bettercommunicationwithrepairyards Hull Lifecycle Programme
Avoid unnecessary repairsthrough assessment of longitudinal strength • Today, measured thickness is compared to maximal diminutions in Excel tables • Repairs can be avoided in cases when longitudinal and local strength is still sufficient with class notation HLP, systematic recalculation of stress distribution etc. is done to avoid unnecessary repairs Hull Lifecycle Programme
TM Case Study, July 2006Measurement campaign Paradise N • Ore Carrier, Reederei F. Laeisz, Rostock • Length 321 m, breadth 58 m, deadweight 322000 t • On voyage from Taranto (southern Italy) to Rio de Janeiro • N&P Maritime- und Industrietechnik GmbH • 14 days on voyage in ballast condition • class renewal partheld • Scope: ballast tanks, cargo spaces, main deck, coaming, hatch covers Hull Lifecycle Programme
TM Case Study Measurement with GL Pegasus • Definition of measurement sequences within Pegasus according to planned fill levels of ballast tanks Hull Lifecycle Programme
TM Case Study Transfer of results • Done at end of day • Transfer of measurement data from UTM device to laptop running GL Pegasus • Checking results using 2D and 3D graphics • Attach photos if requried Hull Lifecycle Programme
TM Case Study End of voyage • Generation of print report including graphics • Hatch covers, aft- and forepeak measurements have been reported conventionally (manual tables and sketches, combined in final report) • Issuance of survey statement referring to TM report Hull Lifecycle Programme
TM Case Study Summary • Measurement procedure itself remains the same • Combined approach poses no problem (conventional tables are also included in GL Pegasus) • System can be used on voyage as well as in yard Hull Lifecycle Programme
The scope of HLP • Initial creation and regular updates of a 3D ship model • GL Pegasus driven Thickness Measurements • Direct Access to TM results via fleet-online • GL Pegasus Viewer software for data visualisation • Class notation HLP • Hull Monitoring based on the 3D ship model available service available 12/08 Use HLP starting with newbuilding phase as a tool for the owner / operator to keep track of the ship’s status Hull Lifecycle Programme
Benefits for Ship Owners and Operators • Easier assessment: graphical overview of thickness measurements • Faster availability of final report • Higher quality of data, no redundant data input • Avoid unnecessary repairs through fast re-assessment of longitudinal and local strength • Use the 3D Model throughout the whole vessel’s lifecycle for • chronological comparison of surveys, • easy comparison between sister ships • Easier communication using graphics (for crew, repair yards, ...) • Clearly document structural condition for administrative bodies, potential buyers, etc. Hull Lifecycle Programme
"The GL Pegasus software produced and developed by GL will provide a professional standard that the industry will rely on for making critical decisions. In addition, the software is easy to use.„ M.
