"The Canadian Navy is planning to procure several Arctic Offshore Patrol Ships (AOPS), for which a design has been developed based on the Norwegian ship Svalbard. This report presents a seakeeping analysis performed using ShipMo3D and an operability analysis performed using SHIPOP2. To facilitate operations in ice, the AOPS design has no bilge keels; thus, roll stabilization using active stabilizer fins or internal tanks is being considered. The present analysis considers stabilizer fins deployed in passive and active modes. Seakeeping computations indicate that roll motions are largest in stern quartering seas at higher ship speeds, and that active stabilizer fins would provide significant roll reduction. Roll stabilization using active pumping between heeling tanks has been examined by modelling the tank system as a ShipMo3D U-tube tank. The results indicate that active fins would be more effective than stabilization using heeling tanks; however, a higher fidelity model of the heeling tank system could yield different results. The present computations and Norwegian experience with Svalbard indicate that inclusion of active stabilizer fins would be warranted"--Abstract, page i.
