Case Studies

A subsea plough used for laying cables in the North Atlantic required a comprehensive overhaul after significant wear developed in its hinge joints. The bores had become oval, and the mating faces showed heavy wear of almost 30 mm, leaving them out of square and compromising the plough’s operational reliability…

During a major shutdown, a steel mill required precise in‑line boring of the main bearings on a critical bump stop assembly. Accurate alignment was essential to ensure smooth, reliable operation once the system was reinstated. Previous temporary repairs had concealed underlying issues rather than resolving them…

A client approached us with a critical requirement: the precision resurfacing of a 2300mm diameter lapping table that had deteriorated over time. The performance of the table was directly impacting their process efficiency, making accuracy and reliability essential…

A major power station required urgent replacement of a leaking joint within a section of critical pipework. The repair demanded exceptional accuracy to ensure minimal disruption to generation. Benroc Engineering was appointed to design and deliver a bespoke machining solution…

We were engaged to carry out precision deep hole drilling on an extrusion press platen. The project required six holes, each 30mm in diameter and 430mm deep, to allow ejector pins to pass through accurately into the mould tooling. All work was completed on site within a strict timescale, as the machine was due to enter service…

A cement works required on‑site machining of four heavily worn shafts located in a restricted operational space, confined between large machine bulkheads. Each shaft measured 375 mm in diameter and had experienced significant wear, requiring precise machining…

Following an accidental spillage of molten alloy steel inside a vacuum Furnace, the door seal became distorted, preventing the oven from achieving an effective airtight seal. The client required an urgent, highly accurate on‑site machining solution to restore the sealing face and avoid extended downtime…

Benroc Engineering was contracted to complete critical machining on a David Brown gearbox after a previous supplier failed to deliver. The gearbox had already undergone weld reclamation on several bores, but the machining stage—required to return the component to OEM specification—remained incomplete. Our team mobilised quickly to recover the project and ensure full dimensional accuracy…

A major steel mill in South Wales contacted Benroc Engineering after discovering excessive wear in several critical pivot pin bores on their Dock‑side crane. The machinery is essential for unloading incoming ships, so fast turnaround and reliable results were vital…
