Orientation

Low-voltage motors in the marine version can be used as main and auxiliary drives below deck on ships and in the offshore industry. The thermal utilisation of the motors is matched to the generally higher ambient temperatures on board ship. If the application demands compliance with additional regulations, e.g. protection against explosion hazards, the appropriate motor series must be chosen.

The classification authorities categorise the drives on board ships into "essential services" and "non-essential services", depending on their field of application. These include the following requirements of the classification authorities:

	Drives for "essential services"	Drives for "non-essential services"
Manufacture in accordance with regulations of the classification authorities	Required	Required
Acceptance test certificate 3.1 according to EN 10204	Required	Only required for motors with certificate
Type test certificate of the classification authority	Required up to a certain limit power	Not required
Individual acceptance test by classification authority	Required above a specific output	Only required for motors with certificate
Supervision of construction and acceptance test certificate 3.2 according to EN 10204	Required by some classification authorities above a specific output	Not required

Typ test

All motors (with the exception of 1LA8, 1PQ8, 1LL8 and 1LH8 motors) are manufactured and type approved in accordance with the regulations of the following leading international classification authorities:

GL (Germanischer Lloyd, Deutschland)

DNV (Det Norske Veritas, Norwegen)

LR (Lloyds Register, Gro?britannien)

BV (Bureau Veritas, Frankreich)

Individual acceptance testing is required in general for motor series 1LA8, 1PQ8, 1LL8 and 1LH8.

As an option, we can manufacture motors in accordance with the following classification authorities:

ABS (American Bureau of Shipping, USA)
RINA (Registro Italiano Navale, Italien)
CCS (Chinese Classification Society, China)

A type test certificate will however on be issued following individual acceptance testing.

Special versions that differ from the range defined in the catalogue are possible on request.

Individual acceptance and supervision of construction

Individual acceptance testing by a representative of the relevant classification authority is required for motors used in essential auxiliary drives, depending on their output:

GL ? 50 kW
LR ? 100 kW
DNV ? 300 kW
BV ? 50 kW

For individual acceptance testing of more than one identical motor in an order, a type test complete with heat run and the corresponding acceptance test must be performed for at least one motor.

In special cases, in addition to the acceptance test, supervision of construction may also be required. Supervision of construction involves monitoring of the separate manufacturing stages of a motor by an inspector from the classification authority.
