SCF Interim Industry Standard – 7 March 2016
Page-2Introduction
Goal-Based Ship Construction Standards for Bulk carriers and Oil Tankers (GBS) define high-levelsafety objectives to be achieved through “functional requirements” and “detailed requirements”. The
conformity of rules and regulations of classification societies with the “functional requirements” areto be verified by procedures. GBS, accordingly, has a five-tier structure consisting of Tier I – Goals,
Tier II – Functional requirements, Tier III – Verification of conformity, Tier IV – Rules andregulations for ship design and construction and Tier V – Industry practices and standards. The
IMO supervises Tier I, II, III and IV, whereas Tier V is dealt with on industry level.
In order to ensure design transparency, one of the “functional requirements” of GBS, each Ship isrequired by the International Convention for the Safety of Life at Sea (SOLAS) to have specificinformation and documentation on ship design and construction onboard the Ship throughout the
Ship’s life. This set of documents, drawings and information is collectively called the Ship
Construction File (SCF).
The documents and drawings required to be provided as part of the SCF contain shipbuilding knowhow. Therefore, all who have access to such sensitive information is expected to give due
consideration to the intellectual property rights (IPR).
At the 2009 Tripartite Meeting (Shipowners, Shipbuilders and Classification Societies) 1 it wasagreed to develop a cross industry concept for ensuring both design transparency and the protectionof intellectual property (IP) which needs to be based on safekeeping certain SCF information at a
dedicated Archive Center ashore.
MSC 87, held in May 2010, stressed the importance of addressing both design transparency and IPR,
supported the cross-industry model presented and noted these proposals. It was also acknowledgedby MSC 87 that detailed standard for SCF would be developed by the industry (Industry Standard).
GBS is applied only to bulk carriers and oil tankers of 150 meters in length and above. GBS-related
rules (amendments to SOLAS Ch. II-1 and regulations concerning GBS) came into effect on January
1, 2012, and the members of the International Association of Classification Societies (IACS)
developed GBS compatible structural rules.
The Industry Standard presented in this document corresponds to GBS Tier V and may be referred toor quoted in the rules and regulations for ship design and construction (Tier IV). The SCF Industry
Standard establishes procedures for implementing the Ship Construction File (SCF), which isdefined by four IMO documents – MSC.287 (87) (adopted at MSC 87 on 20 May 2010), MSC.290(87) (adopted at MSC 87 on 21 May 2010), MSC.296 (87) (adopted at MSC 87 on 20 May 2010)
and MSC.1/Circ.1343 (circulated on 2 June 2010) and supplement those IMO documents based on
MSC 87/5/4 (endorsed by MSC 87).
The Industry Standard was developed in consultation with a cross industry group of the following
industry organizations:CANSI (China Association of the National Shipbuilding Industry);
CESA (Community of European Shipyards’ Associations);
KOSHIPA (Korea Offshore & Shipbuilding Association);1

Tripartite Meeting is a regular annual cross-industry meeting between the high level participantsfrom Shipowners, Shipbuilders and Classification Societies to discuss and agree on prospective
collective actions that will contribute to the development of maritime industry.

SAJ (The Shipbuilders’ Association of Japan);
SCA (Shipbuilders Council of America);
BIMCO;ICS (International Chamber of Shipping);
INTERCARGO (The International Association of Dry Cargo Shipowners);
INTERTANKO (The International Association of Independent Tanker Owners);
OCIMF (Oil Companies International Marine Forum); andIACS (International Association of Classification Societies, Ltd.)The cross industry group has agreed on the following principles.
The SCF Interim Industry Standard (SCF IS) serves as industry guidance and therefore do not oblige
parties to fully follow the contents but rather provide principles, which will facilitate agreement
being reached for each Ship. Such agreements and the resulting commitments will reflect specificindividual situations. In other words, the purpose of the SCF IS is to promote common
understanding of the industry issues involved, and to facilitate agreement on individual projects.
Furthermore, the SCF IS is intended to provide guidance on the principles of how the various parties
manage the information and on taking various actions pertaining to SCF Information. The intention
is to provide users of the SCF IS with practical assistance on the administrative, technical,
operational and document management aspects.
Additional, more detailed guidance for the practical implementation of the SCF IS is provided in theInterim Supplementary Guidance (SCF SG) of the SCF IS.
The principles outlined in the SCF IS could also be used to facilitate the management of information
other than the SCF required by GBS (entered into force in January 2012), which could then be kept
according to a voluntary private agreement between, for example, the Shipowner, IP-Holder and theArchive Center.
The Shipbuilder prepares the relevant SCF Information for design and construction transparency,(see Ch. 3.1)
The Shipowner keeps and updates the SCF Information. (see Ch. 3.4)
SCF Information is to include necessary and sufficient information concerning the Ship’s hull
structure in order to facilitate the Ship’s safe operation, maintenance, inspections and repair as well
as response in emergency situations. (see Ch. 2.1)
Access Right Holders, need to give due consideration to the IPR. (see Ch. 3.2).
All parties should manage SCF Information in accordance with the access and safekeeping
principles provided in the SCF IS. (see Ch. 3.2)
The SCF Supplement Ashore is kept at an Archive Center to ensure both transparency of theinformation and protection of IP. (see Ch 2.1)
Standard storage location of various documents and drawings is provided in Table 2.
The Archive Center keeps the SCF Supplement Ashore and a full copy of the SCF Onboard anddiscloses them to Access Right Holders through the Shipowner. (see Ch. 3.2 and 3.3)

2. SCF Information
2.1. Composition of SCF Information and Scope of Application
SCF Information is a set of documents, drawings and information composed of the SCF Onboard
and SCF Supplement Ashore and collectively refers to information that is sufficient to demonstratethat the Ship meets the GBS functional requirements concerning the hull structure. Such informationis needed for the Ship’s safe operation, maintenance, inspections and repair as well as in emergency
situations. Figure 1 shows the “SCF Onboard – SCF Supplement Ashore” model.

Figure 1: The “SCF Onboard – SCF Supplement Ashore” model
The SCF Supplement Ashore is the part of SCF Information that is highly IP sensitive and kept onlyat the Archive Center ashore. It would usually be provided directly to the Archive Center by the IPHolder upon new-building of the Ship or Update. This is the highly IP sensitive information that is
not absolutely necessary and relevant to be kept onboard the Ship at all times (see Chapter 1“Definitions” and 3.3. “IP Levels”). Any SCF Information which is highly IP sensitive but necessary
and relevant to be kept onboard the Ship at all times (for example required to be on board by IMO
Conventions) should comprise a part of the SCF Onboard. In the case of conventional bulk carriers
and oil tankers, the SCF Supplement Ashore is normally composed of the following four
components:

“Yard plans” drawings(4)(see also page 32) ;and
Master “Lines plan” drawing(5)( see also page 34).

2.2. Definition of SCF Information
The list of information to be included in the SCF is provided in Table 1. The actual names and sets ofsuch documents and drawings may differ from those listed in the example documents or drawings as
they depend on each Shipbuilder’s drawing system. The information provided may be in more than
one document or drawing with appropriate names. Explanatory notes are provided below the Table.
This Table is not identical with the Appendix to MSC.1/Circ.1343, but includes additional items andexplanations which are considered to be relevant to be included in the SCF by the cross industry
group..

(2)

Full “Detailed strength calculation” documents contain the full bulky output of structural strength calculations, which is defined
under Item 3-2 contained in Annex. Summarized information on structural strength calculation is available on board throughdocuments such as Item 3-3 and 3-3A (Plan showing highly stressed areas prone to yielding and/or buckling).
(3)
Full “Detailed fatigue life calculation” documents contain the full bulky output of fatigue life calculations, which is defined under
Item 4-1 contained in Annex. Summarized information on fatigue is available on board through document Item 4-2 (Plan showing
areas prone to fatigue).
(4)“Yard plans” drawings – besides scantling information of structural members – contain also sensitive proprietary information on
fabrication processes. The scantling information of structural members to fulfil the day-to-day needs on board is, however, available
on board, by means of Item 3-5 (Key construction plans) and Item 3-6 (Net scantlings of structural constituent parts) defined in
Annex..
(5)
Master “Lines plan” is a master drawing displaying the detailed hull form of the entire ship. Hull form information frequently
required is readily made available on board, by means of Item 3-5 (Key construction plans) defined in Annex. Hull form informationneeded in emergency situations is also encrypted and stored on ship loading computers on board as numerical data. (Refer to Item 3-11
“Equivalent to Lines plan” defined in Annex, too.)SCF Interim Industry Standard – 7 March 2016

Notes:
1"Key construction plans" means plans such as midship section, main O.T. and W.T. transverse
bulkheads, construction profiles/plans, shell expansions, forward and aft sections in cargo tank(or hold) region, engine-room construction, forward construction, stern construction andSuperstructure (deck house) construction drawings. “Key construction plans” also includes
scantling information of structural members and hull form information on a level meetingonboard needs as defined in Item 3-5 (Key construction plans) and Item 3-6 (Net scantlings ofstructural constituent parts) contained in Annex.
2 "Hull form" means a graphical or numerical representation of the geometry of the hull. Examples
would include the graphical description provided by a lines plan and the numerical description
provided by the hull form data stored within an onboard computer of the Ship.
3 "Equivalent to Lines plan" means a set of information of hull form to be indicated in Key
construction plans and numerical data encrypted and stored on an onboard loading computer of
the Ship, which meet onboard needs in normal and emergency situations. (Refer to Item 3-11
“Equivalent to Lines plan” defined in Annex, too.)
4 If some method alternative to classification rules is applied, declaration of such application andapplied areas need to be indicated.

SCF Interim Industry Standard – 7 March 2016
Page-162.3. IP Levels
The following two IP Levels are defined for SCF documents and drawings considering IP sensitivity,
operational needs and standard access procedures:••

Ordinary IP Level
High IP Level

Standard IP Levels of SCF documents and drawings are shown along with standard storage locationsin Table 2.
These standard IP Levels indicated in Table 2 may be modified for specific Ships subject toagreement between the Shipowner and IP-Holders concerned.
Storage locations indicated in Table 2 may be changed subject to agreement between the
Shipowner and IP-Holder concerned. However, any item required to be on board by IMO
Conventions, and those items listed as being on board in the table are to be on board as aminimum to ensure that they are transferred with the Ship whenever a change of Shipowner takes
place.
All SCF Information will need appropriate care to be taken to safeguard the relevant IP.
2.4. Format of SCF Information
In order to facilitate both the use of the safety related information and the protection of IP, the SCF
Onboard could be stored and used in different formats, e.g. either hardcopies or digital files(including a viewer/browser with printout functionality) at the choice of the Shipowner or inaccordance with requirements of the Flag State and/or port States. A complete set of the SCF
Onboard and SCF Supplement Ashore in a digital format is kept at the Archive Center.
Digital SCF documents need to be stored in a format (software and hardware) that ensurescompatibility with standard hardware/software (standard PC operating systems) and that can be
upgraded in the future to cater for IT technology advancement. Recognized global standards are
expected to be used as far as practical so that there will be no critical access failure when hardware
such as personal computers and/or software such as operating systems and browsers are updated or
renewed, or when the Shipowner or the Archive Center is changed.
Regardless of the format of documents and drawings, the access to and safekeeping of SCF
Information is performed in accordance with the principles provided in Ch. 3.2.

3. Management of SCF Information
3.1. Preparation of SCF Information
Upon delivery of the newly built ship, the Shipbuilder – functioning as co-ordinator of all IP-Holders– provides SCF Information in accordance with the IMO requirements as described below:
i.
ii.
iii.

The SCF Onboard to the Ship;
Copy of the SCF Onboard to the Shipowner’s Office Ashore; andCopy of the SCF Onboard and SCF Supplement Ashore to the Archive Center
3.2. Access and Safekeeping of SCF Information

Shipowner securely keeps SCF Information throughout the Ship’s operational lifetime in order toensure safe operations of the Ship.
Shipowner, for Safe Operation Purposes, can access the SCF Information on board at any time andpermit other Access Right Holders to access SCF Information through the Shipowner under thefollowing principles:••

The IP of SCF Information including confidentiality needs to be protected; andAppropriate procedures to manage access to and securely keep SCF Information in line with
the SCF IS need to be implemented by the Shipowner, e.g. as a part of the Quality
Management Systems.
In principle, the applicable access and safekeeping procedures are to be:
i.
ii.
iii.
iv.
v.
vi.

strict enough to ensure IP protection;
simple enough for smooth access;robust enough for onboard utilization;
durable enough for lifetime service;compatible with standard hardware/software systems in the market; andcost effective.

The access and safekeeping procedures for each IP Level are as follows:a) Ordinary IP Level information: the company document management system as a part of
the Ship’s Quality Management System is expected to include procedures for accessmanagement (e.g., recording of name of document or drawing, access date, name ofaccessing person/organization and the existence of a confidentiality agreement between the
IP Holder(s) and Shipowner needs to be recognized.) It is anticipated that appropriate IT
security procedures to protect information held in electronic form are put in place. These
include periodical renewal of passwords or equivalent and may include periodical renewalof the information to ensure that a complete set of the latest information is used and that the
information has not been compromised.
b) High IP Level information: is stored at the Archive Center ashore. When the Shipownerinitiates the procedures for access to the information, accompanied with information related
to the uses of the information, the Archive Center, in accordance with the specificprocedures, provides the required information after obtaining confirmation by the IP
Holder. After the period of use, High IP Level information is to be returned to the Archive
Center.
Hull form and structural strength information that is required for mandatory Emergency
Response Services (ERS) can be kept by dedicated ERS providers if IPR protection

obligations are acknowledged by the provider such as by means of a confidentiality
agreement. The specific protection obligations and access procedures of the SCF IS may be
modified to adapt to the needs of the ERS.
The full detailed strength and fatigue life calculation documents are available to the Shipowner
during the design and construction period of the Ship, and can after the delivery of the Ship be
provided to the Shipowner from the Archive Center for internal use subject to the requirement not todisclose to any Third Party unless specifically agreed by the IP-Holders. (refer to the Annex, Item 32 and Item 4-1)
In general, it is envisaged that a confidentiality agreement could be developed between the ownerand the IP-Holder. Company procedures for SCF access management need to take account of suchagreement.
3.3. Archive Center
The Archive Center securely keeps SCF Information and arranges appropriate measures for access toand IP protection of SCF Information, in accordance with the principles shown in the SCF IS.
The Archive Center is operated in accordance with the following basic operational requirements.
The Archive Center:

takes a nonpartisan stance;
provides services 24 hours and 365 days in accordance with a predetermined
operational plan in order to respond to any global and urgent requirement to provide
SCF Information kept at the Archive Center;
provides services at least in English;
makes and keeps secure backup copies of the digital documents it keeps;
provides the information on necessary hardware and software, and on relevant software
updates/upgrades, so that accessing individual may access SCF Information kept at theArchive Center; andprovides tools such as browser software to view SCF Information that should becompatible with standard PC operating systems.

The Archive Center provides the SCF Onboard Information after checking whether:••

the party that required Access to SCF Information is either the Shipowner or anotherregistered Access Right Holder; andthe party requesting the information has confirmed that the information is needed for
the Ship’s Safe Operation Purposes.

Archive Center provides the SCF Supplement Information after checking whether:•••

the party that required Access to SCF Information is the Shipowner or anotherregistered Access Right Holder who is making access via the Shipowner;
there is an agreement between Shipowner and IP-Holder; andrequired SCF Information is necessary and sufficient for the purpose.

The Archive Center appointed by the IP-Holder, from accredited candidates at the time of newbuilding of the Ship, needs to be agreed with the Shipowner.

SCF Interim Industry Standard – 7 March 2016
Page-20
3.4. Update of SCF Information
The Shipowner, following any significant event including, for example, substantial repair,conversion or any major modification to the Ship structure that requires Update of the SCF
Information, needs to arrange an Update of the SCF Information.
In such cases, SCF Information before the Update needs to be continuously retained without
destruction or modification along with the updated SCF Information for traceability purposes.
The Shipowner may task the Archive Center to carry out procedures for Update as appropriate.
Updated SCF Information needs to be stored at the same Archive Center that keeps the Ship’s
original SCF Information.
3.5. Use of SCF Information for Purposes other than Safe Operation
The Shipowner is expected to agree in advance with the IP-Holder when SCF Information isdisclosed to a Third Party for purposes other than Safe Operation Purpose, noting that the definitionof ‘safe operation’ includes maintenance, repair, inspection and emergency response.

4. Revision of the Interim Industry Standards
In the event that the IMO requirement is amended or a relevant issue concerning IT progress or useof this SCF IS arises and a proposal is made by any member of the cross industry group (see theIntroduction for its definition) for the revision of this SCF IS, the cross industry group will consider
the need for a revision to the SCF IS. Following agreement of such a need, this SCF IS may berevised as appropriate.
In addition it is anticipated that in the absence of significant issues arising, a general review will be
initiated by the cross industry group within 24 months from 1 July 2016 to take account ofexperience gained in the initial use of this SCF IS.
