3D animation: How to complete an underwater tie in project offshore


The 3D animation below by Nord Stream highlights the process of an underwater tie in project. The pipeline, which is a key natural gas line through the Baltic Sea, was first started in 2011:

As featured in the process, and the video too, the Nord Stream project featured two machines supplied by Mirage Machines. Here’s an introduction to the tooling…

Diamond wire saw

The Mirage Subsea Diamond Wire Saw (DWS) is a subsea or surface cutting solution designed for cutting pipelines, multistring casings, piles, platform legs, wellheads or topsides equipment.

The DSW is ideal for quickly cutting through dissimilar materials and resisting compressive forces. The DWS can be used in surface operations for topside cutting, but is not considered a cold cutting method during this type of work.

Pipe cutting and bevelling machine

A heavy duty split frame pipe cutting and bevelling machine that has been designed primarily for casing cutting and can operate with inserted tooling. The machine can be used to cut through pipe with wall thickness of up to 4” in most materials.

The bevelling machine features a heavy duty split frame design, adjustable preloaded bearing track, counter boring unit and either an air or hydraulic drive.
