For this lifeboat davit winch repair job in Singapore, a customer had recently installed lifeboat winches manufactured by Tsuji Heavy Industries. Both the port and starboard lifeboat winches were not operating as they should so Alatas Singapore was contacted to take a look.

Inspection findings

An Alatas deck machinery engineer carried out a thorough assessment onboard the client’s vessel. They found the internal main drive gears and related drive gears of the gearbox units had seized. This had a knock-on effect causing further damage to cover plates and assembly bearings.

Our solution

We proposed that both Port and STBD lifeboats be removed from the vessel and offloaded to Alatas workshop where we could repair the gearboxes. Our workshop in Singapore is highly-equipped with specialist tools and equipment and a wide range of engineering services on offer.
