Overview

Updated to IACS Rec 55, this publication assists Surveyors of IACS Member Societies, and other interested parties involved in the survey, assessment and repair of hull structures of a general dry cargo ship

This book includes a review of survey preparation guidelines covering safety aspects related to the performance of the survey, the necessary access facilities and the preparation to be undertaken before the surveys can be carried out. This book demonstrates examples of structural deterioration and damage related to each structural area, providing details of issues to be aware of, possible causes and recommended repair methods.

Introduction

The International Association of Classification Societies (IACS) is introducing a series of Guidelines with the intention of assisting the Surveyors of IACS Member Societies, and other interested parties involved in the survey, assessment and repair of hull structures for certain ship types.

The Guidelines are intended for a general dry cargo ship, single skin, which is designed with one or more decks specifically for the carriage of diverse forms of dry cargo.

The Guidelines focus on the IACS Member Societies’ survey procedures but may also be useful in connection with inspection/examination schemes of other regulatory bodies, owners and operators.

The Guidelines include a review of survey preparation criteria which cover the safety aspects related to the performance of the survey, the necessary access facilities, and the preparation necessary before the surveys can be carried out.

The Guidelines encompass the different main structural areas of the hull where damages have been recorded, focusing on the main features of the structural items of each area.

An important feature of the Guidelines is the inclusion of the section which illustrates examples of structural deterioration and damages related to each structural area and gives what to look for, possible cause, and recommended repair methods, when considered appropriate.

The Procedure for Failure Incident Reporting and Early Warning of Serious Failure Incidents - “Early Warning Scheme - EWS”, with the emphasis on the proper reporting of significant hull damages by the respective classification societies, will enable the analysis of problems as they arise, including revisions of these Guidelines.

These Guidelines have been developed using the best information currently available. It is intended only as guidance in support of the sound judgment of surveyors, and is to be used at the surveyors’ discretion. It is recognized that alternative and satisfactory methods are already applied by surveyors. Should there be any doubt with regard to interpretation or validity in connection with particular applications, clarification should be obtained from the Classification Society concerned.
