27、so that it will leave a clear distance of at least 150mm， but not further than 300mm from all bulkheads and structures to be blasted and coated. The distance between the levels and the top level and overhead shall be such as to ensure safe and comfortable reach to all areas to be coated. A distance
28、of approx. 1800-2000mm would for safety reasons be desirable。 The staging must not contact any surface that is to be treated. The ends of all tubular staging poles are to be capped prior to the commencement of blasting work. The capping of staging poles to be done by use of either rubber or plastic
29、caps. Taping is no acceptable as it will not withstand the blasting recoil and blasting media will accumulate inside the poles and cause continuous contamination during the tank coating operation。需冲砂和油漆的舱壁及结构,与脚手架保持至少200mm间距，但不超过300mm。层间高度要能确保安全，并方便油漆施工，出于安全考虑，理想的高度为1800-2000mm.脚手架不能接触任何待涂表面。冲砂前将脚手管
30、两端用橡胶或塑料塞子封住，不可用胶带，因为其不能抵挡反弹的冲砂磨料，会使磨料积累在脚手管中，在油漆施工过程中造成污染。3.2。3 The staging shall not contact the tank top except for the tubular vertical staging supports， which should minimize contact with the substrate.除垂直支撑的脚手管,脚手架其它部位不可接触舱底，并尽可能减小接触面。3.2.4 Adequate safety rails and nets to be provided to perm
31、it safe working and inspection to all surfaces.安装适当的安全扶手和安全网，确保施工和检查工作的安全。3。2。5 The owner reserves the right to demand improvements to the construction and safety of any staging, as well as access to the surface。 In case requested improvement of the staging， whether it may be for safety or poor acce
32、ss to surfaces, owner reserve the right to delay further inspection until satisfactory improvement has been carried out and accepted by owners superintendents。船东有权要求对脚手架的安全性和有效性进行改进.一旦提出了改进的要求，无论是关于安全性或是有效性，船东均可推迟检查,直至改进工作达到船东满意的程度。3。2。6 Staging to remain in place until the tank has passed final coa
33、ting inspection on the overhead and walls。 The staging is then to be carefully removed from the tank without damage to the coating。 Prior to removal of the staging, the tank top, the inside of the main hatch coaming and the surrounding overhead areas shall be protected with rubber sheeting。 During t
34、he destaging operation one experienced member of the tank coating team is to be present in the tank to immediately repair any damages that may occur on the vertical and overhead areas。Directly after repair and touch up of the damages， tape with weak adhesives should be set in such a manner that dust
35、 or blasting media falling from above can not stick to the wet coating.脚手架在舱顶和舱壁的油漆完工检查通过后方可拆除。拆除脚手架时要避免破坏油漆。在拆除脚手架前，用橡胶保护舱底、舱口围及附近的舱顶区域。拆除脚手架的过程中，在舱内安排一名有经验的施工队成员,对舱内顶壁上可能出现的损坏进行及时修补。修补后，用低粘度的胶带贴在修补点上，防止灰尘和冲砂磨料粘在未干的油漆表面上。特涂工艺CARGO TANK LINING PROCEDURE第7页共31页3。2。7 Make one vacuum hose available for
36、 cleaning during de-staging to clean remaining dust and debris.用真空吸砂机清除脚手架拆除过程中残留的灰尘和杂质.3.3 Outfitting Protection舾装件的保护3.3.1 The heating coils should not be introduced in the tanks before tank top coating completion. For obvious reasons the following SUS pre-outfitted items should， prior to pre-blas
37、ting， receive oxidative passivation andthereafter protected by rubber sheeting. Cargo drop lines, cargo drop line supports, heating coil supports， vertical and inclined ladders.It is very vital that these items are carefully protected in order not to have any contact with the blasting medium （copper
38、 slag), as it can contain up to 30 iron and would therefore negatively affect the quality of the stainless steel. After main-blasting is completed and accepted and prior to coating application， the protection on the preoutfitted SUS items shall be completely removed and taken out of the tank. The SU
39、S items are to be cleaned to remove any traces of the blasting medium and dust， and new protection applied。在特涂施工结束后方可安装加热盘管。不锈钢预舾装件要在预冲砂前进行钝化，随后用橡胶保护,包括货油管、货油管管架、加热盘管管架、直梯、斜梯。妥善保护以上这些部件，防止冲砂磨料（铜矿砂）的接触是非常重要的,因为磨料的含铁量可能达到30，会对不锈钢的质量产生负面影响。在主冲砂结束并交验通过准备油漆之前，将不锈钢舾装件上的保护除去并置于舱外,对不锈钢舾装件进行清洁，清除冲砂磨料和灰尘，再施以新
40、的保护.3.3。2 The cargo suction well made of stainless steel is to be blasted and coated same as surrounding。 However, no minimum DFT to be specified。不锈钢吸油井需施以冲砂，做与周围相同的油漆,不规定最低干膜厚度。3。4 Rain/dust protection 雨水/灰尘的防护3.4。1 Sturdy shelters are to be provided to all main access hatches。 In addition, water g
41、uards are to be installed around entrance holes of the tank to prevent rain water from entering the tank。 Rain shelters are to be maintained erected at all times. The shelters shall be capable of preventing dirt, dust, moisture, water and other contaminants from entering the tank and thereby contami
42、nating the immediate entrance area. The shelters are to be of sufficient size to allow personnel to remove and store wet weather clothing outside of the tanks。 No wet weather clothing is to be taken into the tanks。 The floor area shall consist of wooden grating to prevent contamination from foot tra
43、ffic entering the tank。 In addition all personnel shall either change their shoes or wear over-shoes。 主舱口上搭设坚固的挡雨棚,并且，在特涂舱的洞口周围设置挡水，防止雨水进入。挡雨棚要全程维护，使其能够防止污物、灰尘、湿气、水及其它污染物进入舱内污染舱口附近区域。挡雨棚要足够大,可容纳施工人员在舱外脱去并放置雨衣，雨衣不得拿进舱内.舱内近入口处应铺设木栅板以防践踏污染，此外，施工人员需换鞋或戴鞋套.特涂工艺CARGO TANK LINING PROCEDURE第8页共31页3。4。2 Entr
44、ance holes to the tank， other than the main access hatches, are to be protected in such a way that ventilation can be supplied, but protection is provided to eliminate the risk of such contaminants as described above, to enter the tank。主舱口以外的其它洞口要采取保护措施，使其能够用来通风，而避免上述污染物进入舱内.3。4.3 On completion of t
45、he blasting operations the shelters shall thoroughly cleaned.冲砂施工结束后,挡雨棚要彻底清洁。3。4.4 No ventilation or extraction hosing shall be installed in the main access hatch, so as to provide safe and easy entry and exit from the tank。为确保安全和方便出入,风管不得通过主舱口.Note：Any blasted surface or partially cured coating fi
