Underwater Wire Sawing – Precision Cutting in Sea and Submerged Environments

Kristiansand Bygg AS provides underwater wire sawing and underwater cutting services nationwide in Norway for ports, marine structures and industrial projects.

Introduction

Kristiansand Bygg AS provides underwater wire sawing and underwater cutting services throughout Norway.

We perform precise underwater cutting of concrete, steel and rock for ports, marine structures and industrial projects, nationwide. Our services are used in demanding maritime environments where controlled execution, safety and minimal environmental impact are required.

What is underwater wire sawing?

Underwater wire sawing is an advanced cutting method used for precision cutting of concrete, steel and rock in marine and submerged environments. The method uses a diamond wire – a flexible steel cable with industrial-grade diamonds – rotated at high speed to cut material with exceptional accuracy.

This technique enables clean, controlled cuts even at significant depths or in confined spaces, without the use of explosives or heavy demolition tools. Using Kristiansand Bygg AS’ own certified commercial divers or remotely operated ROV systems, wire sawing equipment can be installed and operated efficiently underwater.

Typical underwater operations

  • Underwater wire sawing of quay structures and concrete columns

  • Underwater cutting of ship hulls and vessels

  • Cutting of steel structures and pipelines in sea environments

  • Dismantling of underwater foundations and marine installations

Our expertise in underwater cutting

Kristiansand Bygg AS specialises in underwater wire sawing and marine cutting operations and offers a complete solution combining experience, safety and advanced technology.

We provide an in-house team of certified commercial divers, specialised wire sawing equipment designed for underwater use, and the capability to perform both diver-operated cutting and ROV-based remote cutting.

Flexible choice of method

We adapt the cutting method to the project requirements:

  • Diver-operated wire sawing is suited for shallow depths and lower complexity

  • ROV-based wire sawing is ideal for greater depths, limited visibility or where diver intervention is not feasible.
