1.1 Aim

a . Machinery is to be opened up following sea trials for internal inspection:

(1) To confirm satisfactory design, manufacture and ‘fitness for purpose’.

(2) To investigate, if necessary, the cause of any shortcomings inperformanceor unusual trials observations.

NOTE: Routine maintenance and rectification of defects is to be carriedout in conjunction with the examination where appropriate.

1.2 Selection of Machinery for Examination

a . The Defence Logistics Oganization (DLO) is to specify the machinery to beexamined in each class of ship in accordance with Section 1.4.

b . After experience with the first ships of any Class or Batch, to assist the MODTrials Officer on whom rests the final decision on the opening-up of any item ofmachinery, DLO are to issue a list of items, for which the extent of examinationmay be increased, reduced or waived subject to the performance of themachinery during CST. This list may be amended from time−to−time.

c . For each ship of a class the extent of the examination may be further amendedby the MOD Trials Officer, in agreement with the Resident Project Officer(RPO), should the performance of machinery during trials so dictate. Theagreed list is to be forwarded by the RPO to the Shipbuilder immediatelyfollowing CST with copies to the MOD Trials Officer.

d . The opening-up of machinery, to facilitate examination, is to be kept to aminimum to ensure a satisfactory installation. Where practicable therequirements of examinations are to be met by routine maintenance activities.

e . The RPO may increase the amount of work to be carried out, if defects arediscovered in the course of the examination.

1.3 Conduct of Examination

a . The Shipbuilder is to be responsible for the following:

(1) Opening-up or otherwise preparing for examination such machinery,equipment or systems as required by the DLO and drawing up aprogramme for the work.

(2) Providing the facilities necessary to ensure a detailed inspection andarranging the attendance of all subcontractors. The Shipbuilder is also toarrange for the attendance of the manufacturer’s representatives wherethe equipment is Government Furnished Equipment (GFE),Embodiment Loan Items (ELI), or Commercial off the Shelf (COTS).

NES 353Issue 6September 1999

1.2

(3) Observing cleanliness precautions in accordance with NES 341. Inparticular suitable protection against ingress of dirt is to be provided forany opened-up machinery and for any components or assemblies removedand laid aside. No extraneous work, which may produce dirt such asremoval or application of insulation, preparation for or painting, wiring,drilling or welding, is to be done in any compartment containingopened-up machinery unless approved by the RPO.

(4) Mustering all special tools, lifting gear, cleaning gear and other suchequipment provided for the ship and ensuring that only these are used inthe course of opening-up, cleaning, adjusting and rectifying themachinery. Any defects, difficulties in use or apparent omissions from thekit are to be reported to the RPO.

(5) Rectifying, to the satisfaction of the RPO, any defects disclosed during theexaminations, verifying cleanliness and reinstating the machinery forFinal Machinery Trials (FMT) in accordance with NES 354.

(6) Submitting a report of his findings to the RPO, preferably in the format ofthe Test Form.
