2.1.1 Positional moorings, with or without thruster-assist, are to be
inspected and tested during manufacture/construction and under working conditions on
completion of the installation.
2.1.2 The scope of inspection and/or testing to be carried out at the
manufacturer’s works is to be agreed with Lloyd’s Register (hereinafter referred to
as LR) before the work is commenced.
2.1.4 The planned survey program is to be reviewed and where necessary updated
between each Survey to the satisfaction of the LR Surveyor. A copy of the planned
survey program and updates as agreed with the LR Surveyor, as well as survey
records, are to be kept for information.
2.1.5 The inspection and survey records should be used to track and trend the
observed degradations or anomalies. A PMS condition track record logbook is to be
used to that effect. This is to be updated between each inspection and a copy made
available to LR at every Periodical Survey.
2.1.6 Damage, anomalies and modifications to the positional mooring system
should be reported to LR. Unless the design ensures the Offshore Unit and its
positional mooring system can withstand a line failure with adequate level of safety
(i.e. tension, clearance and offsets still satisfying intact criteria even after one
line failed and still satisfying the damaged criteria after failure of second line)
the unit shall be considered damaged from the time of the failure.
