    An internal airblast from a missile explosion produces tearing, holing and dishing of ship"s structural plating. In order to analyze the residual strength of a ship after an internal explosion, a typical ship compartment was considered to be composed of flat square plates subjected to uniaxial compression, and the damage effects were examined independently. The holing was considered to be a centrally located circle. Plastic limit load analysis of a flat plate indicates that ultimate strength decreases in proportion to increasing hole size. Elastic-Plastic analysis indicates that ultimate strength is little affected by hole size until the holing reaches half the plate width, and is essentially equal to the ultimate load described by the effective width concept. An extension of the concept of small imperfections to dished plates suggests that the ultimate strength is reduced by roughly 10 percent from that of a flat plate. The extensional collapse mode analysis describes folding and strength beyond peak load. Fully plastic crack propagation was examined, but its limiting effect can not be precisely described. A small program of experimentation was developed to gain qualitative insights into the interaction and cumulative effect of the various damage modes. Seven mild steel boxes were constructed of four square side plates with length-to-thickness ratios of 90 and two stiffened end plates to model different damage effects.

    Internal gas explosion pressures intact structure is considered, but the residual strength of the hull after structural degradation caused by wartime damage is also one of the design considerations. damaging effect of an explosion inside a ship is the pressure. A bomb explosion within or immediately nearby a building can cause catastrophic damage on the building's external and internal structural frames, collapsing of walls, blowing out of large expanses of windows, and shutting down of critical life-safety systems.

    The first known conversion of a wooden sailing ship to carry oil in bulk was the Charles. In , the Charles was fitted with 59 separate tanks. Three years later she caught fire and was c. s. petrol 3 internal explosion, sank, , 3 killed la crescenta 29 suddenly disappeared, 29 killed 1. away. After a cargo tank explosion, the vessel is often still afloat, but it now resembles an open shoe box and has about as much residual strength. For salvors, at that stage, the fun begins, and they get to figure out how to remove the cargo and to bring the ship to a safe berth without the vessel folding up.

    was to compare and quantify the strength and stability implications of damage to a CSC-type concept ship, with the idea of highlighting potential design problems. After discussion between DRDC Valcartier and DRDC Atlantic, internal blast was identified as the driving threat to be considered.   Swift () has argued that the shell structure would have had enough residual strength to sustain large and easily detectable cracks if they had grown midway between two window cutouts. However, cracks that grew across a bay from one cutout to the next would not be tolerable and result in ultimate failure of the structure. Fig. s:

Residual strength after fire. In the case of a fire in a compartment of a composite ship there is a major risk that the bulkhead loses its load-carrying capacity due to the high temperature. Therefore these bulkheads are usually fitted with special reinforcements.

The material presented in this book may be used for several M.S. or Ph.D. courses, such as Ship Structural Design, Design of Floating Production Systems, Ultimate Strength of Marine Structures, Fatigue and Fracture, and Risk and Reliability in Marine Structures. This book addresses the marine and offshore applications of steel structures.

This chapter provides an account of the discussions and recommendations received at the 14 th International Ship and Offshore Structures Congress (ISSC) and presents the progress achieved in characterizing the environment.

This session was observed during the three-year term in a manner useful to those in charge of the design and operation of ships and offshore structures. Had those events been produced by a single internal explosion, successive energy peaks – if generated - would have decreased in amplitude.

Accidental damage such as that caused by explosion, fire, dropped objects, extreme environment events, or from ship collision, poses a major threat to the safety and operation of offshore structures.
