2.1.1 Connection
equipment is to be designed to be compatible with ship mooring arrangements
and the limits of acceptable forces, moments and deflections on correctly
applied Connection Equipment resulting from the movement of the moored
ship under normal operational circumstances is to be defined in the
Design Statement.
2.1.3 Connection
to an external electrical power supply is not to adversely affect
the availability of main, auxiliary or emergency machinery, including
ship sources of electrical power to allow ship power to be restored.
Details of arrangements provided to maintain availability (for example,
pre-heating and lubrication and availability of starting, fuel, lubrication,
air and auxiliary systems) are to be included in the Design Statement, see also
Pt 7, Ch 13, 4.5 Ship power restoration and Pt 7, Ch 13, 5.1 General 5.1.9.
2.1.4 The
permanent or temporary installation of electrical equipment in areas
containing flammable gas or vapour and/or combustible dust, is to
be minimised as far as is consistent with operational necessity and
the provision of facilities enhancing the overall safety of the ship
and connection to an external power supply. Where it is necessary
to install electrical equipment in these areas, the arrangements are
to be in accordance with the requirements of Pt 6, Ch 2, 14 Electrical equipment for use in explosive gas atmospheres or in the presence of combustible dusts. The suitability of electrical
Connection Equipment for operation in areas containing flammable gas
and/or vapour and/or combustible dust while in port is to be defined
in the Design Statement and should, additionally, address the implications
for Connection Equipment extended ashore, where applicable, and the
suitability for operation in berths requiring extended, hazardous
areas.
2.1.5 As
far as practicable, Connection Equipment is to be located outside
of areas where it could be damaged by inport activities under normal
operational circumstances.
2.1.6 Consideration
may be given to arrangements that are considered by LR to provide
an equivalent level of safety. Evidence demonstrating compliance with
IEC/ISO/IEEE 80005-1: Electrical installations in ships –
Special features: High-voltage shore connection systems, or
a relevant National Standard may be submitted for consideration of
acceptability by LR.
