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 International Standard specifies the design, minimum safety and functional requirements, inspection and testing procedures for LNG dry-disconnect/connect coupling served for LNG hose bunkering system intended for use on LNG bunker ship, tank truck and shore-based facility etc. This standard is not applicable to hydraulically operated quick connect/disconnect coupler (QCDC) used for hard loading arm since it has been stipulated in ISO 16904. Based on the current technology of industrial manufacturing, the size of coupling from DN25 to DN200 is to be considered and contained within this standard at the development period.

The scope of this standard includes the following five elements.

1) General requirements: basic design principle, design parameters, functional requirements, internal valve, protective cap, handle;

2) Materials: body of coupling, welding, bolting, spring, seals;

3) Interface type and dimensions: Ends termination of receptacle, dimensions;

4) Marking: manufacturer and international standard information;

5) Testing: test conditions, test arrangement, general requirements, verification testing, production testing.

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.

This International Standard specifies technical requirements for windows, portlights, hatches, deadlights and

doors on small craft of hull length up to 24 m, taking into account the type of craft, its design category, and the

location of the appliance.

The appliances considered in this International Standard are only those that are critical for the craft's

watertightness, i.e. those that could lead to flooding due to strength and/or watertightness,

Openings and non-opening devices fitted below Area I are excluded from the scope of this standard.
