为适应新的海工要求，BV重新编写了拖轮入级规范，涵盖的船舶包括海工服务船和海工建造及支持船等。新规范对广泛的海工活动明确了技术要求：拖航、锚作、补给、灭火、污油回收、电缆敷设、潜水支援、起重、重吊运输、备用和救援。新规范启用了管道铺设和居住的入级符号。同时，来自国际跨行业的项目及工作组织（如SafeTug JIP和IMO对稳性的关注）的经验，对规范的编写起到了积极的作用。

　　新规范已经于2017年7月1日生效，作为钢制船舶入级规范的一部分综合在册子NR467-E中。他们代表了BV规范的发展计划的新成就，旨在解决海工操作的一些特殊性技术。

　　NEW RULES FOR OSVS AND TUGS

　　Bureau Veritas has issued new rules covering offshore service vessels and tugs， including offshore construction and support vessels。 The new rules set out technical requirements for a wide range of offshore activities： towing， anchor handling， supply， fire-fighting， oil recovery， cable laying， diving support， lifting， heavy lift transportation， standby and rescue。 They also include new class notations for pipe laying and accommodation。 Experience-based feedback has been incorporated from international cross-industry projects and working groups， such as the SafeTug JIP and IMO groups focused on stability。

　　The new， user-friendly rules entered into force on July 1st 2017 through a dedicated booklet （NR467-E） as part of the Rules for the Classification of Steel Ships。 They represent the culmination of a development plan aimed at addressing the specificities of key offshore operations in Bureau Veritas rules。
