A recently built general cargo vessel experienced a bearing failure on its intermediate propeller shaft bearing. Goltens was contacted to perform an inspection on the bearing shell and pedestal and to propose a solution. Upon inspection it was determined that the entire housing would require repair, due to extensive damage on the bearings, sealing areas, and housing mating surfaces. Further, an inspection of the shaft showed areas of high hardness but no signs of cracks. Goltens proposed that t...
A mining operation suffered a major bearing seizure on the crankpin of a slurry pump shaft. The pump makers approached Goltens to explore the possibility to repair and restore the crankshaft to original diameter in the workshop. Inspection revealed the crankpin had suffered severe damage resulting in surface hardness levels as high as 397 HB and heat cracks on the pin surface. Goltens offered a solution to machine the pin to undersize but the pump maker required the pin diameter at original spe...
At the height of the COVID-19 pandemic in the Northeast United States, in May 2020, Goltens received a call from Bayonne Drydock (Bayonne Drydock and Repair Corp.) to attend for inspection and to make a proposal to remove a damaged shaft seal liner on the USNS Red Cloud, one of the US Military Sealift Command’s nineteen large, medium-speed, roll-on/roll-off ships.

Legend of the Seas was built in 1995 and was the most travelled cruise liner in the Royal Caribbean fleet before she was transferred to another cruise line in mid-2017. Before that transfer, however, a casualty on main engine #5 resulted in significant damage to one of the crankpins. Due to the depth of the crack in the crankpin, the crankshaft could not be salvaged by machining and would require replacement. Large crankshaft replacements are a routine job for Goltens and having completed a suc...
In-place machining eliminates the logistical and cost-related challenges associated with repairing large equipment and machinery that is not easily moved. Goltens’ in-place machining capability is well known when it comes to repairing large-diameter crankshafts but this technology is also successfully applied to repair journals of all sorts and dimensions around the world. As such, machining a damaged 500mm diameter steam turbine generator shaft for Atlas Enerji in Turkey presented no unu...
Goltens Dubai received an emergency call to mobilise to Portugal to evaluate a major casualty on a MAN B&W Hyundai 7L23/30H on an oil tanker. The team evaluated the damaged engine and determined that the engine block and crankshaft were beyond repair and required replacement. Further, the bedplate had suffered major impact damage from the broken connecting rod and piston and its salvage was questionable. Goltens dismantled the engine and rigged the condemned block and crankshaft from the en...
Creating innovative in-place machining solutions that minimise asset downtime and repair costs is what Goltens is known for and has been doing for over 75 years. So when Shanghai Waigaoqiao Power Plant II approached Goltens for an in-place solution to recondition steam valve seats, Goltens stepped up to the challenge. The plant’s two 900 MW Siemens THDF 125/67 coal-fired supercritical thermal units each had two HPSV, HPCV, ISV, and ICV valve seats that required renewal. The challenge was...
Worn slip rings compromise the transfer of current from the rotating component of the generator to the brushes. With time, these can result in poor power transmission and the worst cases arcing and potentially a ring fire resulting in a forced outage. Goltens Rotterdam’s in-place machining experts got the call to machine two sets of slip rings on a 43-year-old BBC generator with heavily worn slip rings. Evaluation with a straight edge showed a highly uneven wear pattern across the surface...
The Diamond Ocean BlackRhino is a Mobile Offshore Drilling Unit (MODU) with large power requirements to meet the demands of its propulsion and drilling plants.

Scope of work Having completed hundreds of ballast water retrofits on systems much larger with greater design challe...
Goltens acquired a “serviced” UG15D governor from a governor repair shop claiming to be Woodward authorised. Physically the governor looked like a UG15D however after further inspection was found to be only partially serviced and rebuilt with incorrect parts and worn parts. Findings Incorrect parts – a smaller pump, incapable of the designed 240 psi output pressure, was used. This meant the governor could not create the required output torque during load transients. This po...
The cargo ship SE Cerulean suffered a major crankshaft failure on its port side main engine.
