Capsizing Performance of Dead Ship Stability for Damaged Ships

Marine Technology Society Journal, 2021
AbstractThis study proposes a method for combining capsizing probability and flooding process to investigate the time-domain dead ship stability of a damaged ship. It focuses on a nonlinear righting lever GZ curve solution in the following aspects: one aspect subjects the influence of damaged tanks on a hull shape to the wind and wave, and the other ...

Occupational Lung Damage in Ships' Repairers

The British Journal of Radiology, 1953
Occupational lung damage in ships' repairers (“boiler-makers”) due to inhaled dust and/or fumes has been described for the first time. Analysis of the materials and the dusts to which those men are exposed while at work revealed the presence of free silica and iron compounds.

A probabilistic method on ship damages

Oceans '04 MTS/IEEE Techno-Ocean '04 (IEEE Cat. No.04CH37600), 2005
Marine accidents especially when considering ship accidents and crashes are addressed here in this paper. In order to identify damage stability in ships and marine vessels, there are basically two main approaches including: deterministic methods, and probabilistic methods.

Reliability and damage of ship structures

Marine Structures, 1988
Abstract This paper presents three areas of ship reliability. The first part treats the buckling collapse of deck plates with distributed initial distortion. At ultimate load, a hinge line is formed across a deck after successive collapses of weaker panels under the extreme wave load during a ship's life.

A Virtual Environment for Decision Support in Ship Damage Control

IEEE Computer Graphics and Applications, 2007
Safety is one of the main concerns in maritime activity. Although the safety of a ship may be determined by many uncontrollable factors (such as weather or human error), efficient and continuous monitoring of shipboard systems and the current safety status is crucial to avoid or at least minimize the effects.

Ship side damage due to collision with icebergs

2013
The growth of the LNG shipping market in arctic seas, due to the discovery of new gas fields in Northern regions, is a main motivation for research in the area of ice loads for ship structures. The focus of the present work is on accidental loads due to collisions with icebergs. More precisely, the scenario investigated includes an impact between small

Damage Stability Requirements for Tankships, Chemical Ships, and Gas Ships

Marine Technology and SNAME News, 1976
This paper reviews the various U. S. regulations, international conventions and IMCO codes which contain damage stability requirements for tankships, chemical ships, and gas ships. A brief history of damage stability standards and background on the development of the 1973 Pollution Convention, the IMCO Chemical Code, and the IMCO Gas Code are presented.

Agent-Based Approach for Ship Damage Control

2016
We here introduce a Multi-Agent System (MAS) approach for solving the crew resources assignment problem whenever a ship, under attack, suffers several damages and, thus, priorities must be assigned in order for it to survive. In the designed system, the ship is the MAS environment and the attacker, equipment, crew and officers (these last ones seen as ...

Structural Safety Assessment of Damaged Ships

Volume 2: Structures, Safety and Reliability; Petroleum Technology Symposium, 2007
In the design of ships, structural strength is generally assessed for the intact condition. In intact condition, the critical load case for mono-hull ship is the vertical bending moment, which reaches its maximum in head seas. Both horizontal bending moment and torsional load may play insignificant role.

Numerical study of damage ship hydrodynamics

Ocean Engineering, 2012
Abstract A RANS based CFD solver with VOF modeling of free surface is employed to investigate the effects of sloshing and flooding on damage ship hydrodynamics. The numerical study includes three research works, i.e. the simulations of forced roll motion of an intact ship, sloshing of water in tank and forced roll motion of a damage ship.
