Practical Seakeeping Performance Measures for High Speed Displacement Vessels
Naval Engineers Journal, 2006The seakeeping performance of high-speed displacement vessels is generally assessed, in a probabilistic manner, by using criteria-based measures of merit. Given a set of seakeeping criteria, these measures, such as the Percentage Time of Operation (PTO) and the Seakeeping Performance Index (SPI), could provide an assessment of the operability of the ...

Seakeeping Performance of Warship Catamaran under Varied Hull Separation and Wave Heading Conditions
PomorstvoSeakeeping criteria significantly impact ship aspects like speed loss, operational optimization, and structural integrity. This study integrated experimental and numerical methods to evaluate the seakeeping performance of an asymmetrical hull with ...

Service – performance and seakeeping trials on a car-ferry
International Shipbuilding Progress, 1970The present analysis of performance data, gathered on the car-ferry m.s. ROI BAUDOUIN, has been largely based on the properties of the apparent slip. The assumption of invariability of wake in this special case of a twin-screw vessel enables the authors to map out a generalized power diagram, that remains unaffected by fouling of the hull.

Seakeeping Performance of NASA’s Orion Crew Module
SNAME 29th American Towing Tank Conference, 2010In the winter of 2008, NASA’s Constellation Program Office initiated a full scale experimental program to quantify the hydrodynamic performance of the Orion Crew Module. The intent of such an experiment was to give real world experience to the DoD recovery forces tasked with recovery of the astronauts and CM after splashdown. The Seakeeping and Marine &

Numerical Study on Seakeeping Performance of a Damaged Ship
Volume 9: Rodney Eatock Taylor Honoring Symposium on Marine and Offshore Hydrodynamics; Takeshi Kinoshita Honoring Symposium on Offshore Technology, 2019Abstract Ships sailing in the sea may encounter collision, grounding or projectile impacting accidents, which may cause hull damage and subsequent compartment flooding. Due to the effect of the flooding water induced moment and the restoring moment, the damaged ship may have inclination and rolling motion.

Proceedings of the Institution of Mechanical Engineers, Part M: Journal of Engineering for the Maritime Environment, 2020
Trimaran hull forms have been very attractive in the past decade. Hydrodynamic performance of trimaran ships is influenced by sidehull arrangement. The present study was intended to construct a surrogate model for better understanding of the hydrodynamic

Seakeeping performance prediction program SKP
1988Description of a computer program which computes predictions of operability time for ships in a seaway is given. The calculations are based on frequency transfer functions of the different ship responses to waves and proceeded in a seaway using operability limiting response criteria which are partly stored in the program and partly to be defined by the

Seakeeping Performance of Fishing Vessels In The Portuguese EConomic Zone
Seakeeping and Weather, 1995The seakeeping performance of fishing vessels is related to some critical values of motion related variables. The motions and accelerations of fishing vessels of different size and type are assessed using linear strip theory methods. Their response to irregular sea states is determined by the special approach and short- term and long-term predictions ...

Quick Evaluation of Seakeeping Performance for Ship Hull Form Optimization
2019At present, most of the ship hull form optimization designs aim to reduce ship resistance. As the ship speed requirements continue to increase, the ship seakeeping performance is also particularly important. A fast and sensitive seakeeping evaluation program is the basis for ship hull form optimization with the aim of seakeeping performance.
