Directive 2009/45/EC of the European Parliament and of the CouncilShow full title

CLASS B, C AND D SHIPS CONSTRUCTED ON OR AFTER 1 JANUARY 2003:

.5 The ships shall comply with the requirements of paragraphs .1 to .4.

.1

Main and auxiliary machinery essential for the propulsion, control and safety shall be provided with effective means for its operation and control. All control systems essential for the propulsion, control and safety of the ship shall be independent or designed such that failure of one system does not degrade the performance of another system.

.2

Where remote control of propulsion machinery from the navigating bridge is provided, the following shall apply:

.1

the speed, direction of thrust and, if applicable, the pitch of the propeller shall be fully controllable from the navigating bridge under all sailing conditions, including manoeuvring;

.2

the control shall be performed by a single control device for each independent propeller with automatic performance of all associated services including, where necessary, means of preventing overload of the propulsion machinery; where multiple propellers are designed to operate simultaneously, they may be controlled by one control device;

.3

the main propulsion machinery shall be provided with an emergency stopping device on the navigating bridge which shall be independent of the navigating bridge control system;

.4

propulsion machinery orders from the navigation bridge shall be indicated in the main machinery control room and at the manoeuvring platform;

.5

remote control of the propulsion machinery shall be possible only from one location at a time; at such locations interconnected control positions are permitted. At each location there shall be an indicator showing which location is in control of the propulsion machinery. The transfer of control between the navigating bridge and machinery spaces shall be possible only in the main machinery space or the main machinery control room. This system shall include means to prevent the propelling thrust from altering significantly when transferring control from one location to another;

.6

it shall be possible to control the propulsion machinery locally, even in the case of failure in any part of the remote control system;

it shall also be possible to control the auxiliary machinery, essential for the propulsion and safety of the ship, at or near the machinery concerned;

.7

the design of the remote control system shall be such that in the event of its failure an alarm will be given. The pre-set speed and direction of thrust of the propellers shall be maintained until local control is in operation;

.8

indicators shall be fitted in the navigation bridge, the main machinery control room and at the manoeuvring platform for:

.1

propeller speed and direction of rotation in the case of fixed pitch propellers, and

.2

propeller speed and pitch position in the case of controllable pitch propellers;

and

.9

an alarm shall be provided on the navigating bridge and in the machinery space to indicate low starting air pressure which shall be set at a level to permit further main engine starting operations. If the remote control system of the propulsion machinery is designed for automatic starting, the number of automatic consecutive attempts which fail to produce a start shall be limited in order to safeguard sufficient starting air pressure for starting locally.

.3

Where the main propulsion and associated machinery, including sources of main electrical power supply, are provided with various degrees of automatic and remote control and are under continuous manual supervision from a control room the arrangements and controls shall be so designed, equipped and installed that the machinery operation will be as safe and effective as if it were under direct supervision; for this purpose Regulations II-1/E/1 to II-1/E/5 shall apply as appropriate. Particular consideration shall be given to protecting such spaces against fire and flooding.

.4

In general, automatic starting, operational and control systems shall include provisions for manually overriding the automatic controls. Failure of any part of such systems shall not prevent the use of the manual override.
