Ashtead Technology Achieves Fast, Efficient and Reliable Offshore Cutting with Diaquip Diamond Wire

Structures targeted for removal often consist of large-diameter steel tubulars, conductors, monopiles, mooring chains, bundles, jacket structures and reinforced concrete components and coatings that have been exposed to decades of corrosion, marine growth and environmental loading.

Diamond wire technology has become an established method for the removal of subsea infrastructure due to its ability to deliver controlled, precise cuts across a wide variety of materials and asset types. Reliable consumables play a crucial role in supporting operations, helping contractors execute complex removal projects safely, efficiently and with minimal disruption to offshore schedules.

While diamond wire saw systems play a vital role in offshore cutting operations, overall performance is heavily influenced by the compatibility of the wire with the cutting system and the quality of the wire itself.

Manufactured using high-quality diamond beads and proven assembly methods, Diaquip wire is engineered to withstand challenging subsea environments while delivering consistent cutting performance.

The wire is subjected to significant loads while cutting through thick-section steel, reinforced concrete and composite structures. It must maintain cutting efficiency while operating in harsh subsea conditions where replacement can be both time-consuming and costly.

High-performance diamond wire can help contractors achieve:
• Consistent cutting action across varying material types
• More predictable cutting rates
• Reliable performance during extended cutting operations
• Reduced operational downtime associated with wire replacement
• Greater productivity from cutting equipment
• Improved planning confidence for complex work scopes

What truly differentiates Ashtead Technology’s cutting capability is not simply the equipment it deploys, but the expertise behind it. With more than two decades of experience delivering subsea cutting solutions, Ashtead Technology has developed a deep understanding of the parameters, techniques and operational practices required to achieve consistent success offshore.

The long-standing relationship between Diaquip and Ashtead Technology has resulted in a highly refined cutting solution that delivers increased cutting efficiency, extended consumable life and reduced operational downtime. By combining Ashtead Technology’s patented cutting system with Diaquip’s custom-engineered diamond wire, this has set new benchmarks for offshore cutting performance.

The results achieved in the field demonstrate not only significant improvements in productivity, but in many cases a step change in cutting capability. Examples include:

• 51″ OD x 30 mm wall thickness Leadon bundles cut in 90 minutes
• 24″ OD x 25 mm wall thickness conductors with 2″ concrete coating cut in 18 minutes
• 36″, 22″, 13 3/8″ and 9⅝” four-string conductors cut in 30 minutes
• 13″ OD flexible pipe cut in 6 minutes
• 4.5” mooring chain cut in 7 minutes

These performance metrics highlight the effectiveness of a collaborative solution, enabling faster project execution, reduced intervention time, delivering enhanced performance, reliability, speed and operational confidence for offshore decommissioning and subsea cutting operations.

The outcome is a market-leading combination of cutting equipment, diamond wire and operational expertise that has been proven across demanding decommissioning, offshore wind and oil & gas projects worldwide.

Ashtead Technology’s continued use of Diaquip diamond wire reflects the importance of product consistency, dependable supply and responsive technical support when delivering challenging subsea projects.

While every project presents different requirements, the need for reliable cutting performance remains constant. Long-term customer relationships are built on trust, reliability and the confidence that critical consumables will perform when required.

For Diaquip, the ongoing support from companies such as Ashtead Technology demonstrates the value of supplying high-performance diamond wire solutions to some of the most demanding cutting environments in the world.
