All the maintenance for the ferries and its assets are pre-programmed, and handled by the engineering department. This department consists of three sections i.e. Mechanical, Electrical, and General Maintenance. The maintenance programmes are divided into the following four categories:

1. Routine Maintenance
This involves the servicing of one ferry on a daily basis. This program is intended to ensure that each ferry is serviced at least once every week as shown in the table below:

2. Planned Maintenance: This is done as per the manufacturer’s schedules.

3. Lloyds Class Requirements: The ferries Nyayo, Kilindini & Harrambe are registered under Lloyds class and fall under the following class service schedules.

(a) Annual Survey: In this survey, ferries are inspected by a class surveyor once a year, checking for mechanical & safety conditions of the vessels.

(b) Docking survey: The class certified ferries undergo docking survey every two and a half years, where the structural conditions, cathodic protection against sea barnacle growth, and general operating equipment is done. This survey is done at the African Marine dry dockyard.

(c) Special Surveys: This is done once every 5 years. This inspection covers a complete overhauling of all operating equipment i.e. the main engines, propellers, general service pumps, safety equipment, communication equipment, generators and e.t.c.

(d) Intermediate Surveys: This inspection is done by the class surveyors at a time determined by the surveyors.
