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.

Air compression in a flooded tank of a damaged ship

Ocean Engineering, 2013
Air compression inside a flooded tank of a damaged ship can significantly delay the flooding process if the ventilation is restricted. This is a notable issue that needs to be considered for example in the design of cross-flooding devices. The problem is studied through systematic full-scale tests with a decommissioned ship, where the ventilation level

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.

Statistics and damage assessment of ship grounding

Marine Structures, 2002
Abstract In this paper, general statistics of ship grounding incidents are considered and the damage extent distributions for Ro–Ro ships are presented from the results of a comprehensive damage data survey conducted using Lloyd's Register's damage database.

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.

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.

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
