8.2.1 The plan(s) for Non-Destructive Examination (NDE), survey, installation
and verification should be produced and agreed with the attending LR Surveyor in
advance. These plans should consider the system fabrication and installation stages
as access may become limited in the latter phases of the construction.
8.2.2 An installation plan should include approved/reviewed drawings, DADs,
material certificates, equipment certificates (if necessary), cabling certificates,
cable penetration certificates, valve certificates, certified welder certificates,
approved welding procedures, approved consumable certificates, NDE plan and, if
applicable, a trial plan.
8.2.3 When necessary, procedures for demonstrating the structural integrity of
an ADU, piping, tanks and watertight boundaries should be presented, reviewed and
then witnessed by the attending LR Surveyor. This should be in accordance with the
(Clasifications Register) Rules and Regulations for the Classification of Ships, July 2022. These
should follow new construction standards.
8.2.4 If considered necessary by the attending LR Surveyor, a speed trial should confirm
that all hull integrated systems are not adversely affected by the bubbles and their
distribution, such as sea chests and water lubricated bearings.
