Four Tier Structure of SCF Provisions

IS defines principles that should be noted by IMO (MSC 96)

UI provide technical details for Archive Centers / SCF users


GBS – SOLAS Ch. II-1 Reg. 3.10 = Mandatory SCF Requirements

MSC/Circ. 1343 = Guidance on the Information to be Included in a SCF

SCF Industry Standard (IS) = Industrial Principles for Access and IPR Protection incl. Content Definition

SCF Unified Interpretations (UI) = Models for Practical Implementation (Procedures)

Executive Summary

1. Introduction

2. Definitions

3. SCF Information Scope – Format– IP Levels – Location

4. Management of SCF Information

Preparation – Access / Safekeeping – Archive

Item 3-2: Bulky output of strength calculation

Definition

A set of detailed structural strength calculations required for approval of structural drawing s

and documents as required by the rules and prepared by a shipbuilder or a classification

society. This is the gen eric terms of calculation for hull structure scantlings decided on the

basis of their capacities for stress, buckling, deformation and any other factors stipulated in

the rules (e.g. collapse, deformation, vibration, noise, corrosion, etc. if required) except for

fatigue which is otherwise defined. This set of detailed structural strength calculations may

be divided into several documents. T his set of detailed structural strength calculation s

includes those approved by the classification society as an alternative method to the rules

using highly advanced techniques peculiar to each shipbuilder, ins tead of those specified by

the rules. This se t of detailed structural strength calculations includes background

information on the calculation procedures such as boundary conditions, load conditions, etc.

as well as names and versions of computer hardware and software as appropriate, results of

the calculations and information stipulated in requirement of the rules.

Models

&

Examples

Results of Finite Element Analysis

Remarks

- It is standard to store such detailed structural strength calculations only at the Archive

Center from the viewpoint of protection of Intellectual Property Rights.

- The models and examples attached in this document are only for a specific design case,

and different set of documents are acceptable as long as they include necessary

information conforming to SCF requirements as a whole.

Item 3-2:

Bulky output of

strength calculation

Definition updated, clarifying that all model

assumptions, loading and boundary conditions, plotted and tabulated results are provided as

detailed by CSR

Examples / Models for user-friendly

presentation of output


CSR Reporting Requirements for Strength Analysis: Model and Input Description

List of plans used including dates and versions;

Detailed description of structural modelling (…);

Plots to demonstrate correct structural modelling and assigned properties;

Details of material properties, plate thickness, beam properties used in the model;

Details of boundary conditions;

Details of all loading conditions (…);

Details of applied loads and confirmation that individual and total applied loads are correct;

Reference of the finite element computer program, including its version and date.


CSR Reporting Requirements Output Description


Summaries and plots of global and local deflections;

Summaries and sufficient plots of stresses to demonstrate that the design criteria are not exceeded in any member;

Plate and stiffened panel buckling analysis and results;

Tabulated results showing compliance, or otherwise, with the design criteria;

Proposed amendments to structure where necessary, including revised assessment of stresses, buckling and fatigue properties showing compliance with design criteria.

The scope of SCF information is now on CSR newbuilding

verification level, justifying the storage in the Archive.

Item 3-11 – Onboard

“Equivalent to

Lines Plan”

Definition: modified to include graphical and (encrypted) numerical

geometrical information

Models and Examples: updated to display key construction plans and

onboard loading computer


1. IP levels and related access procedures: IP levels simplified – high and ordinary;

Access procedures simplified.

2. Detailed strength calculation: Assumptions, conditions, results are provided;

Detail level of input/output increased in line with CSR.

3. Lines Plan and/or Equivalent to Lines Plan: Master Lines Plan protected in Archive;

Equivalent to Lines Plan available onboard;

Numerical geometry data in onboard loading computer.

4. Renewal of password and/or SCF Media Password = yes, SCF Media = maybe.

Substantial items solved since Tripartite 2014


Time plan for SCF finalization

24/25 Sept Cross Industry WG – final draft SCF IS

today Tripartite 2015 – SCF IS progress report

Dec 2015 SCF Approval by all Associations

early 2016 Implementation of SCF IS, start on preparation of Archive Centers

March 2016 joint SCF Submission to IMO, MSC 96

May 2016 MSC 96, IMO notes SCF IS

1 July 2016 GBS/SCF apply to new contracts

1 July 2020 GBS/SCF apply for delivery of new ships

This time plan is ambitious, but manageable, if the IMO spirit of co-operation is maintained!


Thank you for your persistent attention –

I promise to present another topic at Tripartite 2016

Elements of a potential joint industry submission to MSC 96:

Submit final report and present final SCF IS (INF paper);

Request IMO to note the SCF IS (Tier 1 only);

Announce continued development of SCF UI based on feedback from software providers/archive center + SCF users;

Support submission by presentation of SCF IT systems.
