Abstract: The invention relates to an apparatus (12)and method for cutting submerged trees (10)at an underwater logging site and for retrieving the cut trees. Once cut, each tree (10) is retrieved to the water surface by an inflatable bag (24) deployed from and inflated by the apparatus (12). The apparatus (12) includes a control unit (36) positioned on a surface vessel (14), such as a barge or large boat, and an underwater vessel (16) connected together by an umbilical (18). Preferably the underwater vessel (16) is a remotely controllable submersible including a grapple (44) for releasably holding each tree (10) to be cut, a saw, a gas supply connectable to a gas source located on the surface vessel (14), and an air bag deployment and inflation assembly for inflating the air bag (24) and securely attaching it to the tree (10). The underwater vessel (16) is initially loaded with a plurality of air bags (24) which are stored in a magazine located in the interior of the vessel (16). The air bags (24) are sequentially moved from the magazine on to an ejection track at a front end of the vessel (16) disposed above the saw and grapple (44). Each air bag (24) is secured to a cartridge for coupling the bag (24) to the magazine and the ejection track and for holding a tree fastener. In its uninflated state, the air bag (24) is contained within a tubular housing which is releasably connectable to the cartridge. The housing is ejected from the cartridge when the air bag (24) is inflated and deployed.

Abstract translation: 本发明涉及一种用于在水下测井地点切割淹没树木（10）并检索切割的树木的设备（12）和方法。 一旦切割，每棵树（10）通过由装置（12）展开并由其膨胀的可充气袋（24）被回收到水面。 设备（12）包括位于诸如驳船或大船的表面容器（14）上的控制单元（36）和通过脐带（18）连接在一起的水下船。 优选地，水下容器（16）是可远程控制的潜水器，其包括用于可释放地保持要切割的每棵树（10）的抓斗（44），锯，可连接到位于表面容器（14）上的气源的气体供应源， 以及用于使气囊（24）充气并将其牢固地附接到树（10）的气囊展开和充气组件。 水下容器（16）最初装载有多个安全气囊（24），这些气囊被储存在位于容器（16）内部的杂志箱中。 安全气囊（24）从盒子顺序地移动到设置在锯和抓斗（44）上方的容器（16）前端的喷射轨迹上。 每个气囊（24）被固定到用于将袋（24）连接到盒和弹出轨道并用于保持树形紧固件的盒。 在其未充气状态下，气囊（24）容纳在可释放地连接到盒的管状壳体中。 当气囊（24）膨胀展开时，壳体从盒中弹出。
