Based in the coastal region of Southern Norway, Kristiansand Bygg is a specialized contracting firm that has evolved from traditional construction origins into a significant provider of technical services for the maritime and offshore industries. While the company maintains a strong foundation in concrete cutting and drilling on land, it is distinctively recognized in the marine sector for its advanced underwater operations, complex demolition capabilities, and heavy-duty salvage expertise.
The company’s relevance to the maritime domain is anchored in its ability to transfer high-precision construction techniques into harsh underwater environments. A core component of their marine operations is the use of diamond wire sawing technology. This method enables the firm to execute precise cutting of massive steel and concrete structures below the sea surface, a capability essential for modifying port infrastructure, dismantling damaged quays, or removing navigational hazards. This technology has proven particularly vital in wreck salvage operations, where the company utilizes wire saws to section grounded or sunken vessels for safe removal, often in challenging weather conditions.
Beyond heavy demolition, Kristiansand Bygg operates a dedicated diving division that differentiates itself through a philosophy of employing skilled craftsmen who are certified divers, rather than simply training divers to perform manual labor. This approach ensures that underwater tasks—ranging from welding and concrete repairs to technical inspections—are executed with the same level of trade proficiency as surface work. The company’s diving teams are frequently deployed for vessel maintenance duties, including hull cleaning and propeller polishing, which are critical for maintaining ship fuel efficiency and reducing emissions.
The firm also supports port authorities and shipping companies through remotely operated vehicle (ROV) services, providing detailed visual inspections of subsea assets. Their portfolio encompasses the maintenance of marine foundations, sea chest grid cleaning, and rudder repairs. By combining robust engineering methods with specialized subsea access, Kristiansand Bygg serves as a technical problem solver for the shipping and offshore sectors, addressing the complex lifecycle needs of marine structures and vessels along the Norwegian coast.
