Clasification Society Guidance Information - Approval of Longitudinal Strength and Stability Calculation Programs, December 2002 - Chapter 1 Approval of Longitudinal Strength and Stability Calculation Programs, December 2002 - Chapter 4 Certification for a Specific Ship - Section 5 Installation Test
Section 5 Installation Test
5.1 Once the Test Conditions have been endorsed, a copy will be sent to the LR surveyor responsible for issuing the building certificates, together with draft program installation test certificate and instructions to carry out an installation test. In cases where the vessel is in service this information is to be sent to the Owner/Manager, who is to have it placed on board the ship and advise the vessel’s officers that an installation test, witnessed by an LR surveyor, is to be carried out. The surveyor will be instructed to ensure that a user manual is on board.
5.2 Details of the type approved hardware or the first and second nominated non-type approved hardware are to be indicated on the “Program Installation Test Certificate”.
5.3 A note will be made in LR's records that the test conditions have been examined but the installation test is outstanding. Undue delay in arranging the test is to be avoided.
5.4 The LR Surveyor will witness the test being carried out by the ship's personnel (in preference to carrying out the test himself) on the nominated hardware. Data from one ballast and one cargo test condition are to be input manually, with the remaining conditions being loaded directly from stored files on hard or floppy disks. Results IDENTICAL or within the specified acceptable tolerances to the endorsed test conditions should be obtained.
5.5 In cases where type approved hardware is not used, the Surveyor will be instructed to observe a test being carried out on the first and also the second nominated computer which would be used in the event of failure of the prime computer.
5.6 If the test proves satisfactory, the Surveyor will issue a certificate (see Figure 1.7.4 Program Installation Test Certificate) which should be attached to the user's manual or retained with the other ships certificates. Where a program has been tested on two computers the results of both tests are to be satisfactory before a certificate can be issued.
5.7 On receipt of a copy of the Certificate the appropriate plan approval office will make provisions for an entry to be made in the vessel’s Reports and in the Register Book. (See also Sections Ch 1, 1 Introduction 1.13 & Ch 1, 1 Introduction 1.14).
