Marine and offshore

A vessel subjects its components to a combination of constant vibration from the propulsion system, temperature swings from engine room to deck and, in northern waters, ice and frost that place their own demands on material choice. We account for the combined load when selecting tolerance class and surface treatment, rather than considering only the single static dimension on the drawing.

Vibration from the engine and propeller shaft can, over time, loosen threaded joints that were otherwise correctly tightened. We machine locking threads and counter-faces that resist self-loosening and coordinate with the customer's engineer on which locking method suits a given joint, because the right solution varies with where on the vessel the component sits.

In cold waters, low-temperature toughness becomes part of the specification, not just strength at room temperature. We choose and document materials proven at the relevant temperatures, so a component that performs perfectly in summer does not become brittle and crack on a freezing winter night.

Propeller shafts, steering systems and pump components require tight fits, because even a small inaccuracy here causes vibration, noise or reduced efficiency that is expensive and awkward to correct at sea. We machine these parts to the roundness, cylindricity and surface finish needed for bearings and seals to work as intended from the first day in service.

Because many marine components must fit into existing systems, often assembled from several different original suppliers, we focus on measuring against the actual functional dimension rather than only a general tolerance class. That means a replacement part fits even when the original system is made up of components never drawn to match each other exactly.

On critical rotating parts we document balancing and roundness with a measurement report, because imbalance in a shaft part is amplified at high rotational speeds and can cause damage far from the component itself. That documentation travels with the delivery, so the customer's own quality check can be completed quickly without re-measurement.

Yards and equipment manufacturers often work with ship designs that are commercially sensitive long before a vessel is launched. We sign confidentiality agreements as a standard part of working with yards, and access to drawing material is controlled internally, so only staff working directly on the task see the design details.

Many jobs in the marine industry arise urgently, when a vessel needs a spare part at short notice. That requires a way of working where the customer can call directly, send a measurement or a photo of a worn part, and get a response the same day, rather than going through a lengthy quotation process.

We build these relationships over time, learning a customer's vessels, systems and preferred materials, and in return the customer can count on us archiving the production basis, so the next urgent order can be turned around even faster than the last.
