帮忙翻译一下红色的部分，谢谢……？ When there is water over the prospective hydrocarbons,the equipment needed to drill becomes more complicated.The deeper is the water, the more complex theoperation becomes. In shallow water, such as encounteredin swamps, barge rigs are used. A barge rig is simply adrilling rig transported on a shallow water boat. One of the first was Mr. Charlie,' which is shown inFigures 3.10 and 3.11. Mr. Charlie, the first transportable submersible drilling rig, was built in 1953 and served the industry for 32 years. With submersible drilling rigs, the flotation devices are flooded with seawater and sink tothe bottom, providing a stable base from which to operate.首先是如图3.10和3.11所示的查理先生(Mr. Charlie)-建于1953年的第一台移动式能沉入水中的钻机，在产业中使用了32年。有了移动式能沉入水中的钻机，浮动装置装满海水，沉入底部，提供了稳定基础，可在其上进行操作。 the water gets deeper offshore, we use more elaboratedrilling rigs and flotation systems. In water depths upto about 400 feet, we use “jack-up” rigs, which simply themselves out of the water to drill. 仅供参考！查看更多1个回答 . 2人已关注
