载重线公约栏杆斜撑

Emoryyyy · 发表于 2021-8-19 22:47

对船员的保护
公约要求每3档设置一处斜撑，是对所有的栏杆而言？还是只针对干舷甲板和上建的栏杆？还是干脆只露天甲板有这个要求？有区域上的分别么？

讨论规范要求，不要回答什么-船东船检说怎样就怎样做，这样的回答没意义。

既然你知道规范的出处是公约，那你详细看25(2), 25(3)这两条就很清楚了。25(3)明确说了设置斜撑的适用范围是上建和干舷甲板，第一句话就是。

IACS Unified Interpretation LL50

(1982) (Rev. 1 1986) (Rev. 2 1997) (Rev. 3 1998) (Rev. 4.1 October 1998) (Rev. 5 July 2008)
Protection of Crew (Load Line Convention Regulation 25(4), 26(2) and 27(7) and SOLAS II-1/3-3)

(original version of this interpretation also approved by IMO as an unified IMO interpretation, see LL.3/Circ.77 of 1986-10-13, and Rev.4.1 of this interpretation approved by IMO as an unified IMO interpretation, see LL.3/Circ.130 of 1999-06-15)

Interpretation:

When applying Regulation 25(4), 26(2) and 27(7) of the ICLL 1966, as well as Regulation II- 1/3-3 of SOLAS the protection of crew should be provided at least one of the means denoted in the table given below:

_____________

* Oil Tankers, Chemical Tanker and Gas Carrier as defined in SOLAS II-1/2.12, VII/8.2 and VII/11.2 respectively

** Af: the minimum summer freeboard calculated as type A ship regardless of the type freeboard actually assigned.

Hs: the standard height of superstructure as defined in ICLL Regulation 33.

Note: Deviations from some or all of these requirements or alternative arrangements for such cases as ships with very high gangways (i.e. certain gas carriers) may be allowed subject to agreement case-by-case with the relevant flag Administration.

For oil tanker, as defined in SOLAS II-1/2.12, chemical tankers as defined in SOLAS VII/8.2 or gas carriers as defined in SOLAS VII/11.2, constructed before 1st July 1998, existing arrangements which complied with (b) or (c) may be accepted in lieu of (e) or (f) provided such existing arrangements are fitted with shelters and means of access to and from the deck as required for the arrangements (e) or (f) as defined below.

For tankers less than 100 m in length, the minimum width of the gangway platform or deck level walkway fitted in accordance with arrangement (e) or (f), respectively, may be reduced to 0.6 m.

Acceptable arrangements referred to in the table are defined as follows:

(a) A well lighted and ventilated under-deck passageway (clear opening 0.8 m wide, 2.0 m high) as close as practicable to the freeboard deck, connecting and providing access to the locations in question.

(b) A permanent and efficiently constructed gangway fitted at or above the level of the superstructure deck on or as near as practicable to the centre line of the ship, providing a continuous platform at least 0.6 m in width and a non-slip surface, with guard rails extending on each side throughout its length. Guard rails shall be at least 1 m high with courses as required in Load Line Regulation 25(3), and supported by stanchions spaced not more than 1.5 m; a foot-stop shall be provided.

(c) A permanent walkway at least 0.6 m in width fitted at freeboard deck level consisting of two rows of guard rails with stanchions spaced not more than 3 m. The number of courses of rails and their spacing are to be as required by Regulation 25(3). On Type B ships, hatchway coamings not less than 0.6 m in height may be regarded as forming one side of the walkway, provided that between the hatchways two rows of guard rails are fitted.

(d) A 10 mm minimum diameter wire rope lifeline supported by stanchions about 10 m apart, or A single hand rail or wire rope attached to hatch coamings, continued and adequately supported between hatchways.

(e) A permanent and efficiently constructed gangway fitted at or above the level of the superstructure deck on or as near as practicable to the centre line of the ship:

- located so as not to hinder easy access across the working areas of the deck;

- providing a continuous platform at least 1.0 m in width;

- constructed of fire resistant and non-slip material;

- fitted with guard rails extending on each side throughout its length; guard rails should be at least 1.0 m high with courses as required by Regulation 25(3) and supported by stanchions spaced not more than 1.5 m;

- provided with a foot stop on each side;

- having openings, with ladders where appropriate, to and from the deck. Openings should not be more than 40 m apart;

- having shelters of substantial construction set in way of the gangway at intervals not exceeding 45 m if the length of the exposed deck to be traversed exceeds 70 m. Every such shelter should be capable of accommodating at least one person and be so constructed as to afford weather protection on the forward, port and starboard sides.

(f) A permanent and efficiently constructed walkway fitted at freeboard deck level on or as near as practicable to the centre line of the ship having the same specifications as those for a permanent gangway listed in (e) except for foot-stops. On Type B ships (certified for the carriage of liquids in bulk), with a combined height of hatch coaming and fitted hatch cover of together not less than 1m in height the hatchway coamings may be regarded as forming one side of the walkway, provided that between the hatchways two rows of guard rails are fitted.

Alternative transverse locations for (c), (d) and (f) above, where appropriate:

(1) At or near centre line of ship; or Fitted on hatchways at or near centre line of ship.

(2) Fitted on each side of the ship.

(3) Fitted on one side of the ship, provision being made for fitting on either side.

(4) Fitted on one side only.

(5) Fitted on each side of the hatchways as near to the centre line as practicable.

_____
Notes:

1. In all cases where wire ropes are fitted, adequate devices are to be provided to ensure their tautness.

2. Wire ropes may only be accepted in lieu of guard rails in special circumstances and then only in limited lengths.

3. Lengths of chain may only be accepted in lieu of guard rails if fitted between two fixed stanchions.

4. Where stanchions are fitted, every 3rd stanchion is to be supported by a bracket or stay.

5. Removable or hinged stanchions shall be capable of being locked in the upright position.

6. A means of passage over obstructions, if any, such as pipes or other fittings of a permanent nature, should be provided.

7. Generally, the width of the gangway or deck-level walkway should not exceed 1.5 m.

Footnotes:

1. This UI will be applied by all Members and Associates for ships that are subject to the referenced ICLL and SOLAS Regulations.

2. This UI is also applicable to Regulations 25(4), 26(2) and 27(8) of 1988 Protocol.

通读全文，貌似并没有说斜撑是针对露天栏杆的，反而觉得是针对所有栏杆的

根据LL，所有露天甲板都需要设置栏杆，所有栏杆第3个立柱需要设置斜撑。那么是不是所有的露天甲板上栏杆，都需要斜撑呢？你再品一品。
至于船内部通道栏杆，不在讨论之列。
如果不设置斜撑，那么立柱扁铁就需要加大起到斜撑的作用。
