The primary objective of this project is to improve, validate and assess the simplified collision damage model, SIMCOL, to support continuing work by SNAME Ad Hoc Panel no. 6 and International Maritime Organization (IMO) working groups. Work accomplished under prior SSC and SNAME sponsorship made excellent progress towards predicting damage penetration in ship collisions. This project focuses on predicting the longitudinal extent of damage in cases where both ships have forward speed, and at oblique collision angles. Longitudinal damage is particularly important in oil outflow and damage stability calculations. Current models do not provide adequate predictions of longitudinal damage, particularly in way of transverse bulkheads. The specific tasks completed in this project are: Developed SIMCOL Version 3.0 including: (1) deformable Bow sub model and (2) implementation and validation of theory for the determination of energy absorbed in longitudinal extent of damage; Developed the capability to model collision events using LSDYNA used in simplified model development and validation; Validated Virginia Tech LSDYNA ship collision modeling procedure; and Validated SIMCOL using real collision data, and probabilistic collision data for penetrating collisions.
