An apparatus to make a custom length pipe nipple, and method for use of the apparatus. The apparatus has a male plumbing thread at one end connected to an elongate member, with length or measurement markings along the elongate member. The apparatus is threaded into a plumbing fixture that will be flush mounted against a wall, and then using the markings on the elongate member, a length is determined that corresponds to the flush mounting surface of the plumbing fixture. The apparatus is then threaded into a plumbing fitting, such as a drop ear elbow inside a wall, and a second length is determined that corresponds to a flush mounting surface of the wall. The two lengths are added together to determine the length of a piece of pipe. Tightening and/or caulk allowance may be included, and a piece of copper or iron pipe is then cut to length. For copper pipe, a threaded male copper fitting is solder attached to each end. For iron pipe, the ends are threaded. Depending on whether copper or iron pipe is used, there are different length or measurement markings along the elongate member.

A restraint system for use in securing temporary flow lines that include multiple pipe sections, each pair of pipe sections connected together with a fitting or coupling such as a hammer joint coupling. The system includes multiple pluralities of endless loop slings connected end to end with a cow hitch or girth hitch knot. Disconnectable fittings (e.g., shackles) are placed every three or more slings so that easy disassembly is afforded in case of leakage or other failure.

This invention relates to a hydrate plug remover for removal of a hydrate plug in a tube. The hydrate plug remover includes a collecting container provided with a valve in a lower end portion. The valve connects the collecting container to surroundings of the hydrate plug remover. The collecting container in an upper end portion is provided with a circulation gate connecting the collecting container to the surroundings of the hydrate plug remover.

Systems and methods for securing a remotely operated vehicle (ROV) to a subsea structure during cleaning, maintenance, or inspection of the structure surface are provided. In one or more embodiments, an attachment mechanism includes a pair of grasping hooks that are raised and lowered when driven by a motorized drive. In one or more embodiments, an attachment mechanism includes a rigid holder having a mechanical stop and connected to a swing arm, the swing arm configured to rotate inward, but not outward beyond the mechanical stop. In one or more embodiments, an attachment mechanism includes a plurality of linked segments in series, each connected at a plurality of pivot points. A pair of wires passes through the plurality of linked segments and connects to a pair of pulleys that extend or retract the wires, thereby rotating the plurality of linked segments.
