What is a bollard pull test?
A bollard pull test measures a vessel's static pulling force at zero speed against a fixed point using a towline and load monitoring. The results provide documented verification of towing performance for acceptance trials, contractual requirements and operational planning.

Pipe fabrication and cold bending
Our cold bending process results in pipes of consistent quality and long service life. The process shapes the pipes without heating, preserving the material properties and reducing internal stresses. At the same time, it minimises the need for welded joints, increasing structural integrity and reducing the risk of leaks.
Through our affiliated company, we also offer hot-dip galvanising, an effective, long-term corrosion protection solution for steel structures and components.
Hot-dip galvanising
We offer hot-dip galvanising services through our wholly owned subsidiary, Vestsink, a specialised provider with more than 50 years of experience. Galvanising provides effective, long-term corrosion protection for steel structures and components, supporting durability and reduced maintenance over the vessel or asset lifecycle.
