Tokyo – ClassNK has granted its Innovation Endorsements for Products & Solutions to two elemental technologies of “CMP-MAP”, “Performance estimation method of ships based on hull roughness and fouling condition” and “Performance and operational analysis solutions”, provided by Chugoku Marine Paints, Ltd. (CMP).
Performance estimation method of ships based on hull roughness and fouling condition and Performance and operational analysis solutions
“Performance estimation method of ships based on hull roughness and fouling condition” is a technology that estimates the impact of each antifouling paint on ship performance and CII rating based on measured hull roughness and other data. “Performance and operational analysis solutions” visualizes the antifouling paint performance based on operational data, etc., and suggests antifouling paint suited to the operational profile of each vessel.
ClassNK has verified the functions of the “Performance estimation method of ships based on hull roughness and fouling condition”, 1. continuous acquisition of numerous roughness parameters and 3D images over a wide area of the hull on shipbuilding sites using the portable “CMP 3D Hull Roughness Analyzer HRA-3000”, 2. estimation of changes in hull resistance by calculating the friction increase rate (FIR) from the surface roughness profile using the “FIR theory version 3.0”, 3. estimation of ship performance and CII rating based on the FIR values of each antifouling paint taking into account biofouling and aging using the “PIR Simulator”.
For “Performance and operational analysis solutions”, ClassNK has reviewed 1. performance evaluation methods for visualization of antifouling paint performance, based on on-board monitoring data, 2. operational profile analysis methods for visualization of fouling risk and finding out suitable antifouling paint setting, based on on-board monitoring data or AIS data, 3. providing services as a Solution Provider (SP) defined by IoS-OP. After conducting verifications on each, ClassNK has issued certificates.
ClassNK will continue to further promote its Innovation Endorsement for Ships, Products & Solutions, and Providers, and strive to support innovative technologies and initiatives.
