1.3.2 Risk analysis reports

When risk analysis is performed, a detailed report for risk

analysis with a detailed follow-up report of actions and mit-

igation measures taken in response to risk analysis findings

are to be submitted to the Society for information.

Note 1: Risk analysis reports are considered for information only, to

ensure that findings and conclusions of the risk analysis are prop-

erly taken into account for the design of the wind propulsion sys-

tem.

1.4 Operating manual and maintenance

instruction manual

1.4.1 Operating manual

Wind propulsion system is to operate within conditions as

given by the operating manual, see Sec 5, [1.2].

The operating manual is to be kept available on board the

ship.

1.4.2 Maintenance plan

Rules of the Society are listed in Tab 1.

Table 1 : Reference to other Rules of the Society

2 Definitions

2.1 Wind propulsion system types

2.1.1 The following types of wind propulsion systems are

considered in the present Rule Note:

• Modern rig:

Rig with one or further masts supporting mainsail and

headsails, equipped with or without spreaders and sup-

ported by transverse shrouds and forestay and backstays.

The sails are trimmed to the wind by the running rig-

ging.

• Traditional rig:

Rig with further masts supported by transverse and lon-

gitudinal standing rigging shrouds, with yards support-

ing square sails and with headsails. The sails are

trimmed to the wind by the running rigging.

• Free-standing rig:

Rig that doesn’t rely on shrouds and stays to keep the

masts up. As a rule, self supporting rigs have only head-

sail trimmed to the wind by the running rigging. The

mast can be fixed or turned by rotation.

• Free standing rotating rig:

Free rotating mast with integral rigid boom extending

fore and aft of the mast supporting the sail tacks. The

sails are trimmed to the wind by rotation of the mast.

• Modern square-rig:

Free-standing and rotating masts with curved yards rig-

idly connected to the mast. The sails furl into the mast

and are trimmed to the wind by the rotation of the mast.

• Wing sail:

Wing, reefable or not, fixed to a free rotating mast with

as a general rules integral long boom. The wing sails are

trimmed to the wind by rotation of the mast.

• Kite rig:

Kite not supported by mast and trimmed to the wind by

kite control lines.

• Rotor sail:

Free-standing rotor generating an aerodynamic lift force.

• Suction wings:

Orientable wing with internal ventilated system to use

boundary layer suction effect.

Wind propulsion system can be telescopic, articulated,

tilted.

Other type of wind propulsion devices are to be examined

on a case by case basis by the Society.

2.2 Standing and running rigging

2.2.1 Standing rigging

The standing rigging means the masts and all the equipment

and accessories permanently fixed to the mast and to the

hull used to support the wind propulsion system (see Tab 2).

It includes elements essential to the overall integrity and

safety of the wind propulsion system.

2.2.2 Running rigging

The running rigging means the rigging elements used for

setting, furling, shaping, trimming and controlling the wind

propulsion system and accessories fixed to the hull used to

support these elements (see Tab 2).

It includes elements the failure of which might induce only

localised effects.

Table 2 : Standing and running rigging

2.3 Ship hull areas

2.3.1 The ship hull areas are the hull areas supporting the

reaction forces and moments induced by the standing and

running rigging.

These areas are mainly the local hull structure reinforce-

ment in way of:

• mast step

• pad eyes and chain plates

• main and fore sheet track rails

• winches and clutch

• sheave supports.

2.4 Risk analysis

2.4.1 Risk analysis is a structured method involving:

• identification of hazards related to the ship, installation

or equipment

• estimation of hazard probabilities or frequencies

• estimation of hazard consequences.

2.4.2 HAZID - Hazard Identification

The HAZard IDentification (HAZID) is a structured method

for identifying hazards, threats and consequences affecting

assets, environment, human life or economy.

It consists of a brain-storming workshop with designer and

client personnel engineering disciplines about project man-

agement, commissioning and operations.

2.4.3 HAZOP - Hazard and Operability Study

A HAZard and OPerability (HAZOP) study, also known as

process hazard analysis (PHA), is a well-proven, structured,

team-based method for process hazard identification com-

monly used during the process design phase or for pro-

posed modifications.

HAZOP makes detailed examination of the process and

engineering intention of new or existing facilities to assess

the potential hazards from operating outside of the intended

design, or malfunction of individual items of equipment and

their consequential effects on the facility as a whole.
