Section 1 Survey requirements

1.1 General

1.1.1 When a Special Survey is due, it is to be established with the Owner/Naval Authority that it will coincide with a planned maintenance period for the vessel. The Surveyor is to discuss, prior to this period, with the Owner/Naval Authority which areas will need to be “opened-up” for survey in order that these may be incorporated within the maintenance programme, see Ch 9, 3.1 General 3.1.1.

1.1.2 Survey requirements are specified in Vol 1, Pt 1, Ch 3 Periodical Survey Regulations of the Rules and Regulations for the Classification of Naval Ships (hereinafter referred to as the Rules for Naval Ships).

1.1.3 Surveys are to be carried out by Exclusive Surveyors unless alternative arrangements are agreed with LR prior to the survey being commenced.

1.1.4 Surveyors who are not fully experienced in such inspections are to be joined by an experienced Senior Surveyor.

1.1.5 A Docking Survey should be carried out concurrently with the Special Survey.

1.1.6 At Special Survey, or modernization refits, naval ships are often inactive for a considerable time (months). Most surveys will be carried out at the beginning of this period and therefore care needs to be taken in ensuring that the ship receives suitable allowance for this in assigning a date for survey, at the same time ensuring that the condition of the items surveyed remain efficient until the next survey period.

1.1.7 If the Special Survey, or the Continuous Survey cycle, is completed more than three months before the due date, then the actual date of completion should be recommended for assignment. In all other cases the due date should be recommended.

1.1.8 Only in exceptional cases can an extension beyond the due date be given and all requests for such an extension are to be referred to the LR Naval liaison office. In general, any extension would normally be for a maximum period of three months to enable the vessel to complete its duties. Only if the vessel is on a deployment can the extension be extended beyond this limit. Upon satisfactory completion of surveys required for an extension of the Special Survey, the Certificate of Class is to be endorsed in the appropriate section and the validity of the certificate extended as advised by the LR Naval liaison office.

1.1.9 Survey periodicity may be amended, see Vol 1, Pt 1, Ch 2, 4.5 Existing ships – Periodical Surveys 4.5.12 of the Rules for Naval Ships.
