Safety is the main criterion on board ship, then let it be the safety of the crew onboard or the safety of the equipment. To make sure that the equipment onboard a ship is being taken care of a record of tests and examinations to be kept on board. For safekeeping of lifting appliances, a chain register is to be carried onboard.
“A register of the lifting appliances and items of loose gear shall be kept in form prescribed by the competent authority, account being taken of the model recommended by the International Labour Office.”
A Chain Register Register is to be standard international form as recommended by the International Labour Office in accordance with the ILO Convention No. 152. Chain Register to be maintained up to date as per the requirement of the Dock Safety Regulation and endorsed and signed by a competent person as required. It contains a certificate of tests and registers all reports of examination of load-bearing machinery, chains and wire ropes before they are put in use.

Contents of Chain Register
A Chain Register is divided in three parts:
Entries to be made:
- Situation and description of lifting appliances and loose gear (with distinguishing number or marks, if any) which have been thoroughly examined
(If all the lifting appliances are thoroughly examined on the same date it will be sufficient to enter in here “All lifting appliances and loose gear”. If not, the parts which have been thoroughly examined on the dates stated must be clearly indicated.)
- Certificate Numbers of the Gears
- Examination Performed
The thorough examinations to be indicated in this part including:
- 12 monthly
- Five yearly
- Other thorough examinations including those associated with heat treatment.
- Remarks, if any (To be dated and signed)
- Date and Signature
Part 2 – Regular Examination of Loose Gear
Entries to be made:
- Situation and description of loose gear (with distinguishing number or mark, if any) which has been inspected
(All loose gear should be inspected before use. However, entries need only be made when the inspection discloses a defect.)
- Signature and date of the responsible person carrying out the inspection
- Remarks (To be dated and signed)
Part 3- Annealing of chains, rings, hooks, shackles and swivels (other than those that are exempted)
Some loose gears are exempted, which are as follows:
- Chain made of cast iron
- Plate link chain
- Chains, rings, hooks, shackles and swivels made of steel
- Pulley blocks
- Hooks and swivels having screw-threaded parts or ball bearings
- The tests, examinations, and inspections indicated in this Register are based on the requirements of the ILO Convention No. 152 and Recommendation No. 160.
- These recommendations are intended to ensure that ships’ lifting appliances are initially certified by a competent person and to establish periodically that they continue to be in safe working order to the satisfaction of a competent person acceptable to the competent authority.
- A Register of Lifting appliances and items of loose gear shall be kept in a form prescribed by the competent authority, account being taken of this model recommended by the International Labour Office.
- This Register and related Certificates shall be kept and be available to any person authorized by the competent authority.
- The Register and Certificates for gear currently aboard the ship shall be preserved for at least five years after the date of the last entry.
Initial Examination and Certification
- Every lifting appliance shall be certified by a competent person before being taken into use for the first time to ensure that it is of good design and construction and of adequate strength for the purpose of which it is intended.
- Before being taken into use for the first time a competent person shall supervise and witness testing, and shall thoroughly examine every lifting appliance.
- Every item of loose gear shall, before being taken into use for the first time be tested, thoroughly examined and certified by a competent person in accordance with national law or regulations.
- Upon satisfactory completion of the procedures indicated above the competent person shall complete and issue the Register of Lifting Appliances and attach the appropriate Certificates. An entry shall be made in Part I of the Register.
- A rigging plan showing the arrangement of lifting appliances shall be provided. In the case of derricks and derrick cranes the rigging plan should show at least the following information:
- the position of guys;
- the resultant force on blocks, guys, wire ropes, and booms;
- the position of blocks;
- the identification mark of individual items;
- arrangements and working range of union purchase.
Periodic Examinations and Re-testing
- All lifting appliances and every item of loose gear shall be thoroughly examined by a competent person at least once every 12 months. The particulars of these thorough examinations shall be entered in Part I of the Chain Register.
- Re-testing and thorough examination of all lifting appliances and every item of loose gear are to be carried out:
- after any substantial alteration or renewal, or after repair of any stress-bearing part; and
- in the case of lifting appliances at least once in every five years.
- The re-testing referred above may be omitted provided the part which has been renewed or repaired is subjected by separate test, to the same stress as would have been imposed on to it if it had been tested in situation during testing of the lifting appliance.
- The thorough examinations and tests referred to in Point 2 are to be entered in Part I of the Register.
- No new item of loose gear shall be manufactured of wrought iron. Heat treatment of any existing wrought iron components should be carried out to the satisfaction of the competent person. No heat treatment should be applied to any item of loose gear unless the treatment is in accordance with the manufacturer’s instruction; to the satisfaction of the competent person. Any heat treatment and the associated examination are to be recorded by the competent person in Part I of the Register.
Regular visual inspections of every item of loose gear shall be carried out by a responsible person before use. A record of these regular inspections is to be entered in Part II of the Register, but entries need only be made when the inspection has indicated a defect in the item.
