The basic configuration is designed to be able to operate for up to six months without the need for scheduled maintenance. All maintenance activities for the Wärtsilä Power solution for normally unattended installations can be performed efficiently using “walk to work” support vessels, eliminating the need for permanent operational and maintenance crew on site. The solution can be extended to include the maintenance of power management, automation and auxiliary equipment. It is a holistic power solution that can be tailored according to the requirements of each individual installation.
