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.

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.

Ship collision damages: Case studies

2019
Closed-form expressions to estimate the collision energy and damage extent for ship collision analysis have been developed and finalized in Zhang et al. (2019a). This analysis procedure has also been adopted in the Guidance Notes for Collision Assessment for the Location of Low-Flashpoint Fuel Tanks (Lloyd’s Register 2016) and for collision risk ...

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.

Performance assessment of damaged ship hulls

Ocean Engineering, 2013
In this paper, a probabilistic framework for performance assessment of ship hulls under sudden damage accounting for different operational conditions is presented. Grounding and collision accidents are considered as sudden damage scenarios. The combined effects of sudden damage and progressive deterioration due to corrosion are investigated.

Ship Damage Stability Enhancement through Crashworthiness

2023
Crashworthiness as one of the Risk Control Options (RCOs) for damage stability enhancement has been around since the 1990s, potentially earlier. Yet, it has never managed to gain inroads for routine use in ship design and operation to enhance ship damage stability cost-effectively, more specifically targeting passenger ships.

Repairing Ship Damage in Forward Areas

Naval Engineers Journal, 1991
ABSTRACTThis paper describes Navy plans for ship battle damage repair (SBDR). The goal is to repair battle damage as far forward as possible. This would return lightly damaged ships to service quickly, reduce time lost for transit and save heavily damaged ships for subsequent repair.

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.
