Abstract:
Objectives In order to define the advanced grade of the existing Semi-Submersible Crane Vessel (SSCV), evaluate whether the ship design achieves the expected effect, and find out the existing problems to guide the future work,
Methods an advanced grade evaluation index system and an evaluation method suitable for SSCV in service is proposed with reference to national standards and combined with characteristics and functions of SSCV. And the applicability and feasibility of this evaluation method are determined through the actual calculations.
Results The calculation results show that the proposed advanced grade evaluation index system and evaluation method are applicable to the evaluation of SSCV in service, and the evaluation results are in line with the engineering practice.
Conclusions The proposed method herein can provide a reference for the advanced grade evaluation of SSCV under design.
