CLASSNK S EXPERIENCE WITH BWMS RETROFITTING Day 2 - Wednesday, 28 September 2016 Session Ratification in 3 2 1 0.5 0.25 BWMTech North America ClassNK Principal Research Scientist Shinichi Hanayama
Backgrounds BWMS retro-fitting is important for the smooth implementation of BWM Convention (BWMC) just after September 2017. A significant demand for retrofitting from 2017 to 2021 is expected. For the smooth implementation, not only the production capacity of BWMSs but also design/yard/survey capacity for retro-fitting should be needed. This is our first challenge!! Efforts by all stakeholders will beneeded. 2
MEPC 69 approved draft amendments to regulation B-3 of the BWMC, and a draft MEPC resolution on Determination of the date. The draft MEPC resolution recommends that existing ships, constructed before the date of entry into force of the BWM Convention, should install BWMS by the date of the first renewal survey of the ship associated with the IOPP Certificate. The renewal survey IOPP certificate should be performed every 5 years, therefore all existing ships should be retro-fit with BWMS in 5 years after the date of entry into force of the BWM Convention. How many existing ships to istall BWMS? 3
How many existing ships should be retrofit with BWMS in 5 years? ClassNK used IHS Fairplay ship database of January 2016 to determine the number of existing ships, required to install BWMS to comply with the application schedule of regulation B-3, as amended Ships of < 400 gross tonnage and not engaged in international voyages are excluded. It is estimated that approximately 35,000 ships would be required to install BWMSs. 4
Under the current requirement, it is quite natural that retro fitting works will be performed together with the dry docking duration for RS of IOPP certificate. It should also be noted that the total duration of docking may be extended according to the work for retrofitting. Such additional time may reduce the dockyard capacity for retrofitting. Therefore, it is crucial to develop a practical solution to increase the capacity from both way. 5
Difficulty of BWMS Installation a) Confined engine room space (already optimized to house existing machinery, without additional spaces for BWMS and piping) b) BWMS retrofitting needs extensive network of various piping, because of its complex construction and operation (both on ballasting and de-ballasting). c) Difficult to obtain accurate 3D models of engine rooms required for detailed planning 6
Process of BWMS Retrofitting Phase 1 Phase 2 Phase 3 Preliminary Study Outline Design Onboard Examination & 3D Scanning Phase 4 Phase 5 Phase 6 Phase 7 3D CAD Data Make up Detailed Design Preparation for Retrofit Retrofitting at shipyard 7
Preliminary Study Phase 1 There are over 50 BWMSs, which have been already approved. UV Chemical Electrolysis Preliminary Study Ozone etc. Check Points Space utility in engine room and/or pump room (depended on BWMS with Hazardous gas) Electrical power capacity assessment Assessment of ballasting/de-ballasting rating, capacity etc. Cost assessment including OPEX Whether ship will be operated in US waters. Decision on which BWMS to install 8
Outline design Phase 2 Outline Design Rough planning BWMS Retrofitting, such as location, preliminary piping arrangement, etc., according to existing 2D figures 9
Onboard Visible Examination 8 Phase 3 Onboard Examination Check Points Deciding installation locations and ancillary work for machinery installation Pathway planning of additional pipes Electrical modifications including ballast control system Onboard access route for each components 10
Onboard measuring by 3D Scanning 9 Phase 3 Onboard 3D Scanning Scanning Range : 0.6-330m Scanning Angle : Horizontal ; 360, Vertical ; 305 Scanning Speed : Max 976,000pt / Sec Accuracy of measurement : +-2.0mm Scanning with camera to add visible coloring to each dots 11
Onboard measuring by 3D Scanning a) 3D scanning is carried out according to the design outline developed. b) Scanning can be carried out in 3 to 6 hours by two engineers C) Collected data consists of billions of point data not only XYZ positioning but also RGB information. 12
3D CAD Data Development Phase 4 3D CAD Data Development New Software is needed Point Cloud Data with its colour 3D CAD Data,which can be exported to the existing CAD system 13
Joint R&D supported by ClassNK R&D of new technology for application in 3D laser scanner Project Period: April 2012 June 2014 Object: To develop software with highly accurate measurement capabilities that can allow for quick utilization of measurement data from 3D laser scanning data of ships Participants: ClassNK, NYK Line, Mitsui O.S.K. Lines, "K" Line, Sasebo Heavy Industries, Sanwa Dock, MTI, The University of Tokyo, ClassNK Consulting Service, ARMONICOS, S.E.A. Systems 14
Characteristics of ClassNK-PEERLESS a) The Software can run on a basic work station. b) Rich stencil template for basic components (such as pipes, valves, etc ) has been already prepared, c) Automatic pipe recognition function d) Easy to transfer the 3D CAD data to famous 3D CAD Software, used for Maritime. Exporting to AVEVA Marine in 5 minutes and exporting to CADMATIC through CADMATIC exchange in 1 minute., and c) Have been updated according to the feedback from Ship yards and designers. 15
Advantage of ClassNK-PEERLESS More accurate 3D modeling can be easily made. Processing period for modeling can be shortened to one week (from 1 month). 16
