This International Standard specifies performance and testing requirements for the gas inflation systems for inflatable life-saving appliances complying with the requirements of the 1974 Safety of Life at Sea Convention (SOLAS 74), as amended, and the IMO International Life-Saving Appliance Code (LSA Code), adopted by IMO Resolution MSC.48(66).

For the purposes of this International Standard, the gas inflation system consists of inflation gas, Gas cylinder valve, Gas cylinder operating head, high-pressure hoses, and pressure-relief, inflate/deflate, non-return and transfer valves. This International Standard addresses only systems in which compressed inflation gas in cylinders is used as the inflation medium.

As national requirements for qualification, use, and testing of Gas cylinders vary widely, general requirements for Gas cylinders are not addressed in this International Standard, but should meet the requirements of the applicable regulatory bodies. Furthermore, the corrosion resistance of the Gas cylinder shall be appropriate to the requirements of Chapter 1 of LSA Code. The systems addressed in this International Standard are of the type generally used in primary life-saving appliances such as survival craft, marine evacuation systems, and means of rescue; systems used in personal life-saving appliances, such as inflatable lifejackets, are addressed in Part 7 of ISO 12402.

This document specifies the requirements and recommendations for cathodic protection systems applied to the internal surfaces of metallic tanks, structures, equipment, and piping containing raw or treated seawater or brackish waters, to provide an efficient protection from corrosion.

Cathodic protection inside fresh water systems is excluded from this document. This is covered by EN 12499.

NOTE EN 12499 covers internal cathodic protection for any kind of waters, including general aspects for seawater; but excluding industrial cooling water systems. This document specifically details applications in seawater and brackish waters.

This document applies to light offshore cranes including their supporting pedestals and structures.

NOTE The supporting pedestal and structures such as columns and boom rests are covered by this standard to the extent where their main purpose is to support the crane.

This document is applicable to light offshore cranes, whose structures are made of steel.

The following characteristics distinguish light offshore cranes from other types of offshore cranes:

— maximum rated capacity 20 tonnes, maximum load moment 300 tm;

— limitation for off-board lifting operation Hs = 2,0 m and wind speed 15 m/s (3s gust);

— maximum number of working cycles class U3 (C ≤ 1,25 × 105) according to EN 13001-1.

This document gives requirements for all significant hazards, hazardous situations and events relevant to light offshore cranes, when used as intended and under conditions foreseen by the risk assessment (see Clause 4).

This document is not applicable for:

a) transportation, assembly, disabling, scrapping or changing the configuration of the crane;

b) non-fixed load lifting attachments, i.e. any item between the hook and the load;

c) lifting operations in ambient temperatures below −20 °C;

d) lifting operations in ambient temperatures above 45 °C;

e) lifting operations involving more than one crane;

f) accidental loads due to collisions or earthquakes;

g) emergency personnel rescue operations (except training);

h) subsea lifting operations;

i) general purpose offshore cranes, floating cranes and motion compensated cranes.

This document is applicable for the lifting of personnel.

This document is applicable to light offshore cranes, which are manufactured after the date of approval by CEN of this document.
