Pumping crude oil ashore is a round-the-clock business that depends on onboard generators to provide vital electricity supplies.
Removing a generator from service is a project that requires significant planning and technical expertise to ensure a cost-effective maintenance.
For one oil and gas operator, that meant assigning Sulzer with the task of refurbishing one of its crucial assets.
The floating storage and offloading (FSO) vessel was built in 2003 and operates off the coast of Nigeria with a capacity of 2.2 million barrels of crude oil, which are pumped ashore via a 38 km (24 mile) pipeline.
Operating in a particularly challenging environment, 15 years of continuous operation had taken their toll and the owners were planning some refurbishment projects, one of which related to an onboard generator.
During the course of operation, the 27 MW generator developed a stator winding fault that meant it could only operate at half of its design capacity.
As such, the unit was assigned as a back-up generator until the stator could be rewound. The operators of the FSO began planning for...
