The determination of CRS requirements for class entry depends on the fact whether the vessel has previously been classed with a classification society being IACS member or not.
In most cases transfer to CRS class can be combined with normal survey requirements, minimising costs to the owner and disruption to operations.
Transfer of Class Procedure
In general, this procedure can be divided into three phases:
Submission of the application form
Submission of technical documentation
Carrying out of the class (and statutory surveys) and issuing of the certificates.
Depending on the type of transfer of class appropriate TOC Request form is to be filled-in and submitted to CRS
1. Submission of the application form
An agreement called "Transfer of Class Agreement (TOC)", existing between IACS members, enables the current status of the vessel assigned by the previous classification society to be obtained by CRS directly from that society. TOC requirements are comprising the following ceases also: dual classification of the vessel with other IACS class society, double classification, transfer of class on ship delivery.
If all surveys and pertinent recommendations are found up-to-date, it should only be necessary to carry out a survey in accordance with the TOC.
It is to be noted that in cases of transfer of class from non IACS member class society specific requirements, different from below stated, are to be applied. In such cases CRS Head Office is to be contacted in order to obtain specific requirements developed for each particular case.
Application for Initial class entry survey with CRS should be made by the interested party by submitting form "REQUEST FOR SURVEY FOR CLASSIFICATION" (click here to download), dully filled-in, signed and stamped by the applicant.
Form dully filled-in, signed and stamped should be sent to CRS Head Office initially by fax as follows:
To: CROATIAN REGISTER OF SHIPPING, Split, CROATIA
Attn. to: Coordination division
Fax. No.: + 385 (0)21 358 159
By receiving this fax from the applicant the process is immediately initiated.
Original of the form should be mailed afterwards by the applicant to the following address, also:
CROATIAN REGISTER OF SHIPPING
2. Submission of technical documentation
The following technical documentation should be submitted:
≈ Hull & hull equipment
General arrangement plan
Ship's body lines
Stability book and Hydrostatic curves
Rudder and rudder stock
Single-line wiring diagram
Intermediate, thrust and screw shafts

≈ Additional plans for ships with ice class notation
Plans for flexible couplings and/or torque limiting shafting devices in the propulsion line shafting
≈ Torsional vibrations
For ships less than two years old, torsional vibration calculations should be submitted.
Alternative technical data may be accepted in lieu of specific plans not being available at the time of the transfer.
3. Carrying out of the class surveys and issuing of the certificates
The survey of the vessel for the purpose of issuing Certificate of class is to be performed to the following extent:
1. Survey of hull:
a) For ships of age less than 5 (five) years the survey is to be held at the extent of Annual survey.
b) Additionally, for ships between 5 (five) and 10 (ten) years of age the survey is to include inspection of a representative number of ballast spaces.
c) Additionally, for ships of 10 (ten) years of age and above, but less than 20 (twenty) years of age, the survey will include inspection of a representative number of cargo spaces.
d) For ships with affixed ESP notation, (vessels subjected to IACS UR Z10.1, Z10.2, Z10.3, Z10.4 or Z10.5) which are 15 (fifteen) years of age but less than 20 (twenty) years of age, a full Special or Intermediate survey is to be carried out, whichever is due next.
e) For all ships, which are 20 (twenty) years of age and above, a full Special survey is to be carried out (this requirement is also applicable to vessels having their hull under continuous survey).
f) In the context of applying of d) and e) above, if a dry docking survey is not due at the time of transfer, consideration can be given to carrying out an underwater examination in lieu of dry docking.
g) In the context of applying items a) to f) above, as applicable:
- If the class entry survey is to be credited as a periodical survey for maintenance of class consideration may be given by CRS to the acceptance of thickness measurements taken by the losing society provided they were carried out within the applicable survey window of the periodical survey in question.
- If the class entry survey is not to be credited as a periodical survey for maintenance of class, consideration may be given by CRS to the acceptance of thickness measurements taken by the losing society provided they were carried out within 15 months prior to completion of class entry survey when it is in the scope of a Special survey, or within 18 months prior to completion of class entry survey when it is in the scope of an Intermediate Survey.
In both cases, the thickness measurements are to be reviewed by CRS for compliance with the applicable survey requirements, and confirmatory gauging are to be taken to the satisfaction of CRS.
h) In the context of applying c) to f) above, as applicable, tank testing for vessels over 15 years of age is not required to be carried out as part of the class entry survey unless the class entry survey is being credited as a periodical survey for maintenance of class.
i) In the context of applying a) to f) above, as applicable, compliance with IACS URs that require compliance at the forth coming due periodical surveys (such as IACS UR S26 and UR S27) are not required to be carried out/completed as part of the class entry survey unless the class entry survey is credited as a periodical survey for maintenance of class.
2. Survey of machinery installation
General examination of all essential machinery shall be held comprising the following:
a) examination under working conditions of oil fuel burning equipment, boilers, economisers and steam/steam generators. The adjustment of safety valves of this equipment is to be verified by checking the records on the vessel,
b) all pressure vessels,
c) insulation resistance, generator circuit breakers, preference tripping relays and generator prime mover governors shall be tested and paralleling and load sharing to be proved,
d) in all cases, navigation lights and indicators shall be examined working and alternative source of power verified,
e) bilge pumps, emergency fire pumps and remote controls for oil valves, oil fuel pumps, lubricating oil pumps and forced draught fans are to be examined under working conditions,
f) recirculating and ice clearing arrangements, if any,
g) the main and all auxiliary machinery necessary for operation of the vessel at sea together with essential controls and steering gear shall be tested under working conditions. Alternative means of steering shall be tested. A short sea trial should be held at the discretion of CRS if the vessel has been laid up for a long period,
h) initial start arrangements shall be verified,
i) in the case of oil tankers, the cargo oil system and electrical installation in way of dangerous spaces shall be checked for compliance with the Rules of CRS. Where intrinsically safe equipment is installed, CRS shall satisfy himself that such equipment has been approved by the organisation recognised by CRS. The safety devices, alarms and essential instruments of inert gas system shall be verified and the plant generally examined to ensure that it does not constitute a hazard to the vessel.
4. Carrying out of the statutory surveys and issuing of the certificates
For the purpose of issuing statutory certificates the following is to be noted:
1. If statutory certificates are issued directly by the Flag State Administration, these will remain valid on transfer of class, and the whole process will be limited to class matters only.
2. If statutory certificates were issued by the previous classification society, being IACS member, on behalf of the Flag State Administration, and are still valid, these certificates will be accepted by CRS.
3. Above stated is not applicable in those cases where a change of flag is involved, as specific instructions will be forwarded to the applicant by CRS Head Office. Additional surveys and a plan review may be required by the new Flag State Administration.
In no case the existing class of the vessel should be cancelled with the previous classification society, until confirmation of the acceptance of the vessel into CRS class is received from CRS Head Office.
The vessel is to be fully prepared for the survey (including necessary facilities) and sufficient time is to be ensured in order to enable CRS surveyors to perform the survey.
The best time to initiate the process for class change is when some, or all of class and statutory surveys are becoming due. By following this rule additional costs, deriving from unscheduled withdrawal of the ship from trading or similar will be automatically avoided.
Before starting the survey it is strongly recommended to sent copies of all existing class and statutory certificates, together with copies of exemption certificates, if any.
Try to complete and submit as soon as possible all required technical documentation, preferably before starting the survey.
