本统一解释旨在就防跌落装置的强度和试验标准提供指导。 “关于现有救生艇钩的评估和更换导则”(MSC.1/Circ.1392,见我社 2011 年145 号通函)的第 4 段中强烈敦促在确认救生艇钩符合经修正的 LSA 规则之 4.4.7.6.4 至 4.4.7.6.6 之前,应安装防止救生艇跌落装置 FPD  。而在“安装和使用 FPD 导则” MSC.1/Circ.1327 (见我社 2011 年 145 号通函)中涉及了安装和使用 FPD 的要求,却 没有提出强度和海洋环境的适应性要求。

本统一解释弥补了 MSC.1/Circ.1327 在这方面的疏漏。 其他注意事项如下:

1.FPD  可分为两类,一类为在艇钩上设置插销的类型;另一类为两段带有连接件的短 索的类型;

2.对于上述第一类 FPD,如需对原艇钩进行改装,需要原艇钩制造厂接受;

3.对于上述第二类 FPD,在安装时需原救生艇制造厂及原吊艇架制造厂确认原设备的 眼板是否适用于拟安装的 FPD。

实施要求

除主管机关另有规定外,我社将对 2013年1月1 日及以后提交认可申请的 FPD 实 施本通函的要求。

本通函在本社网站(www.ccs.org.cn)上发布,并由各分社转发所辖区域内的有 关船厂、产品制造厂、设计院及航运公司。

实施中如有问题,请联系总部技术管理处。

附件     IACS UI SC 254

(Rev.6.220100101-111)

SC254(April 2012)

Fall Preventer Devices

(MSC.1/Circ.1392 and Circ.1327)

MSC.1/Circ.1392, Paragraph 4

Member Governments are strongly urged to ensure that all ships which are fitted with on-load release systems for lifeboats, are equipped with fall preventer devices as per paragraph 6 of these Guidelines at the earliest opportunity.

MSC.1/Circ.1392, Annex Paragraph 6

On each ship, fall preventer devices in accordance with the Guidelines for the fitting and use of fall preventer devices (FPDs) (MSC.1/Circ.1327) should be employed for each existing lifeboat release and retrieval system ……

MSC.1/Circ.1327, Paragraph 2

The use of FPDs should be considered as an interim risk mitigation measure, only to be used in connection with existing on-load release hooks, at the discretion of the master, pending the wide implementation of improved hook designs with enhanced safety features.

Interpretation

Where locking pins are provided as a FPD, the pins shall be designed so that they have a minimum factor of safety of 6 as per LSA Code Paragraph 6.1.1.6. Where existing on-load release hooks are drilled to provide a locking pin insertion point, the strength of the hooks shall continue to satisfy the relevant requirements in the LSA Code and MSC 81(70), Part.2 section 5.3.1 and shall comply with the requirements of MSC.1/Circ.1327 paragraph 2.1. The modification of the hook in this respect must be acceptable to the manufacturer of the hook.

Where strops or slings with fittings (with fittings e.g. shackles) are used as a FPD, they shall be approved against the following test requirements:

(i)   Environment tests as set out in MSC 81(70) Part 1, Paragraphs 1.2.1 or equivalent. (ii)   Tests for rot-proof, colour-fast and resistant to deterioration from exposure to sunlight

and that they are not unduly affected by seawater, oil or fungal attack as set out in MSC

81(70) Part 1, Paragraphs 2.4 or equivalent. (iii)       Prototype test to a factor of safety of 6.

(iv)        A factory acceptance test of 2.2 x SWL.

NOTE

This Unified Interpretation is to be uniformly implemented by IACS Societies for the approval of FPDs submitted on or after 1 January 2013.

Note: the factor of safety shall be based upon the 5叭儿,which shall be not less than the total weight of the lifeboat when loaded with its full complement of persons and equipment

It is the responsibility of the lifeboat and davit manufacturer,to confirm that the atlachment eye is suitable for the use of the proposed FPD. If the lifeboat and/or davit manufacturer is n longer available,the suitability is to be determined by an independent service provider
