Theme;    Testing of watertight compartments
Title of the presentation; Testing of tanks and tight boundaries
Presenter;   Mr. O Kitamura (Mitsubishi Heavy Industries, Ltd., Japan)

Abstract
SOLAS regulation II-1/11.1, which entered into force in the beginning of 2009, does not require mandatory hydrostatic testing of watertight compartments which are not intended to contain liquids. SOLAS regulation II-1/11.2 and 3, however, require hydrostatic testing of double bottom (including duct keels), inner skins and tanks which are intended to contain liquids.  These requirements have brought both flexible and inflexible interpretations, and caused serious confusion.  Based on the questions raised by EMSA of EC, IACS took actions and proposed draft amendments to SOLAS and practical guidelines for testing tanks and tight boundaries at MSC 86 (June 2009), which will be discussed at DE in a couple of years.  A summary of IACS’s proposal and EMSA’s concern is reported in this presentation.

Theme;    Environmental FSA (Formal Safety Assessment)

Title of the presentation;  Environmental FSA for oil tanker

Presenter; Mr. Yasuhira Yamada 

(National Maritime Research Insutitute, Japan)

Abstract

Formal Safety Assessment (FSA) has been widely used to evaluate cost-effectiveness of new regulations from the view point of “safety” in IMO. As increase of society’s concern to environment, Environmental Risk Evaluation Criteria (EREC; in other words environmental FSA) is under development within the framework of formal safety assessment since MEPC57. On the other hand at MEPC58 Demark has submitted results of FSA study for oil tankers as an outcome of EU Project SAFEDOR, where several risk control options such as increase of double side space/double bottom height are judged as cost-effective.
In this presentation, status of the present discussion of EREC in relation to proposal submitted by Denmark is presented.

Theme;    PSPC(Performance standards for protective coatings) for ballast water tank
Title of the presentation; Useful and reliable technology for PSPC – Automated soluble salt measurement and further challenges beyond
Presenter;   Mr. H.Obata (Namura Shipbuilding Co., Ltd., Japan)

Abstract
PSPC for Seawater ballast tank have already been adopted, however, there are still further questions being raised while the shipbuilders acquired experiences. PSPC was established on basis of the technology existed at the time, but there has been a great deal of development in technologies. And PSPC does not exclude any alternative technologies and systems with proven equivalent performance. The Shipbuilding industries among Asian countries should share this perception and address to review the PSPC in order to achieve our smooth, efficient and productive management. In this presentation, our concrete activity, which is developing the method of automated soluble salt measurement and proposing to IMO in the future for realization above our targets, is introduced.

Theme;    PSPC(Performance standards for protective coatings) for ballast water tank

Titleof the presentation; Uniform application of PSPC

Abstract

A series of IMO PSPC was discussed in IMO during several years and final PSPC resolution for cargo oil tank of crude oil tank was adopted at MSC 87.  The first IMO PSPC resolution for water ballast tank was started to apply in Korean shipyards without any reference industry standards or codes hence, Korean shipyards develop their own standard practice so called KSPIP (Korean Shipbuilders’ Painting and Inspection Practice). Interpretations on the resolution including guidelines are still arguing among the parties concerned and application procedures are different from each shipyards therefore, a unified interpretation/understanding of the requirements and uniform application of the resolution is vital important in order to keep a smooth shipbuilding process.  
 
1 Introduction
We should recognize a series of IMO PSPC and its requirement in detail and its interpretations currently available for uniform application of the resolutions.

2 Industrial standards and codes
KOSHIPA prepared a guideline for applying the PSPC, so called KSPIP, which is drafted based on documents of The Guideline for Implementation of PSPC, IACS UI SC 223 IACS PR 34 and JSRA/JSTRA - SPSS, etc.
Some Classification society comments on the KSPIP with different interpretation on the resolutions and reference documents without any technical background and it make a trouble on applying PSPC hence; more reliable standards based on same understanding on the existing documents considering coating quality and performance such as ISO standard are needed for smooth application of PSPC.

3 Progress on ISO standards
A series of new ISO standards for PSPC application currently being discussed in ISO TC8/SC8/WG5 and a draft CD (Committee Draft) will be finalized within this year. Another standard for salt measurement and surface preparation will also be developed and discussed in ISO TC8/SC8/WG5, a participation on the working group will be helpful.

4 Conclusions
The shipyards should have an initiative in application of the resolutions with proper preparation in both hardware and software aspect and should establish a unified procedure for application including inspection standards in order to keep a certain quality level of PSPC which required by the resolution.

Theme;   GBS (Goal-based ship construction standars) - Design transparency and intellecutual propaty protection

Abstract

GBS Syllabus
1. Decided time table for bulk carriers and oil tankers of 150 m in length and above applying GBS.
GBS has the five-tier system and the three upper tiers had been developed.
Tier 1, Goals
Tier 2, Functional requirements
Tier 3, Verification of compliance criteria
Tier 4, Technical procedures and guidelines, classification rules and industry standards
Tier 5, Codes of practice and safety and quality systems for shipbuilding, ship operation, maintenance, training, manning, etc.

2. The tier 4 of GBS includes the classification rules. International Association of Class Societies (IACS) is undertaking a project to develop Harmonized Common Structural Rules (HSR)  which is based on the current two separate sets of IACS Common Structural Rules (CSR) for oil tankers and bulk carriers.

2.1 By this way, the benefit to IMO is that it will need a significantly reduced effort to undertake the verification procedure and to the shipbuilder is that reduced abrupt changes for the ships’ scantlings.

2.2 Current CSRs includes CSR for tankers and CSR for bulk carriers. The goal of CSRs is to set up common minimum structural requirements for the design and construction of robust ships, based on transparent methods, supported by published technical background documents and providing a rational link between the requirements for new buildings and ships in service. Some functional requirements had already been considered, i.e. designed life, environmental conditions, fatigue strength, etc.

2.3 The two CSRs are developed independently, consequently, there are different approaches for some key items:
 - wave load,
 - buckling criteria
 - fatigue requirement

2.4 Gap between current CSR and GBS functional requirements
 - ultimate strength, especially for ships withstanding impact loads and spring loads
 - residual strength
 - structural redundancy

2.5 We should be aware that HSR is not the final solution for GBS. It is agreed that a risk-base methodology should be further adopted. Being shipyard or design agencies, it’s better to contribute in such development.

3. Ship Construction File (SCF)
3.1 SOLAS, CHAPTER II, PART A-1, REG.3-10 “A Ship Construction File with special information on how the functional requirements of the goal based ship construction standards for bulk carriers and oil tankers have been applied in the ship design and construction shall be provided upon delivery of a new ship”

3.2 GBS Tier II, the requirement for design transparency, which is not covered by current rules.

3.3 SCF should include the following information
- Areas requiring special attention throughout the ship’s life.
 - All design parameters limiting the operation of a ship.
 - Any alternatives to the rules, including structural details and equivalency calculations.
 - Approved and stamped “As built” drawings and information which incorporate all design alteration approved [and stamped] by the classification society or flag State during the construction process.
 - Procedures for updating the Ship Construction File over the lifetime of the ship throughout the ship’s life.
 - Net scantlings for all the structural members.
 - Minimum hull girder section modulus along the length of the ship which has to be maintained throughout the life of the ship ship’s life.

There is some intellectual property (IP) sensitive items included.

3.4 Framework of SCF
SCF onboard 
SCF supplement on shore archive
To balance the transparency requirement and IP protection.
High IP sensitive documents including strength analysis, as built drawings, hull form and fatigue assessment are kept onshore.
The optimized hull form is the key IP for yards.

3.5 Questions for SCF ashore archive.
- Who’s going to run the ashore archive
- how to supervise the access control 
- who’s going to choose the archive

Theme;    GBS - H(C)SR (Harmonized common structural rules)
Title of the presentation; Views on IACS harmonized CSR from the shipbuilding industry
Presenter;   Mr. Kohta Shibasaki  (Universal Shipbuilding Corporation, Japan)

Abstract
International Association of Classification Societies (IACS) is now developing the new common structural rules which will incorporate the tanker rules (CSR-OT) and the bulk carrier rules (CSR-BC), and are called as “Harmonized Common Structural Rules” (HCSR). The one of big challenges of HCSR is to involve the requirements of the Goal Based Standards of IMO which include some technologies beyond the state-of-the-art.
In this presentation, the views on the development of HCSR by IACS and the suggestions for corporation by Asian shipbuilders for smooth implementation of HCSR will be expressed.
