Case Study

Supporting Large-Scale Offshore Decommissioning with Diaquip Diamond Wire

Client

Mactech Offshore USA

Project

Subsea Infrastructure Removal at Depths up to 6,500 ft

Industry

Subsea Decommissioning

Overview

Mactech was selected by a global client to support a major offshore decommissioning project requiring the removal of subsea infrastructure at water depths of up to 6,500 feet.

Using its 16-inch ROV Diamond Wire Saw in combination with the client’s remotely operated vehicle (ROV), Mactech successfully completed more than 200 subsea cuts using Diaquip diamond wire.

The Challenge

Large-scale offshore decommissioning places significant demands on cutting equipment and consumables. Working at depths of up to 6,500 feet leaves limited opportunities to inspect or replace consumables, while vessel time and offshore intervention can significantly increase project costs. With more than 200 cuts to complete, dependable wire performance was essential.

The Diaquip Solution

Diaquip supplied the diamond wire used by Mactech throughout the project. Selected for dependable performance in demanding offshore environments, the wire supported Mactech’s 16-inch ROV Diamond Wire Saw, helping deliver smooth, consistent cutting across a high-volume subsea cutting campaign.

The Results

Working with its global client, Mactech successfully completed the project using its ROV Diamond Wire Saw and Diaquip diamond wire.

• More than 200 subsea cuts completed
• Water depths up to 6,500 feet
