Curriculum
Programme Structure
The programme is structured in 5 modules, listed below in order of study.
01
Fundamentals of internal networks on board, naval connectivity and basic architecture of boat communications
- Concept of internal network in boats and differences between domestic network, corporate network, industrial network and embarked maritime network
- Typologies of on-board networks: navigation network, administrative network, crew network, passenger network, technical network and entertainment network
- Main Components: Routers, Switches, Access Points, Wiring, Antennas, Servers, Firewalls and Connected Devices
- Particularities of the maritime environment: vibration, humidity, salinity, interference, limited space and dependence on external connectivity
- Relationship between internal network, navigation systems, satellite communications, automation, security and comfort on board
02
Cabling, network equipment, Wi-Fi and physical design of on-board infrastructure
- Cabling types: Ethernet, Fibre Optic, Coaxial, PoE power and installation criteria in naval spaces
- Manageable Switches, Routers, Access Points, Wi-Fi Controllers, Racks, Patch Panels and Power Supplies
- Wireless coverage design in cabins, lounges, deck, bridge, engine room and outdoor areas
- Pipelines, mechanical protection, labelling, cable organisation and prevention of moisture or vibration failure
- Power supply, backup, UPS, surge protection and continuity of critical equipment
03
Configuration of networks, segmentation, addressing and internal services of the ship
- Basics of IP addressing, DHCP, DNS, NAT, VLAN, subnets and basic routes
- Network segmentation for navigation, crew, guests, CCTV, entertainment, automation and administration
- Configuration of routers, switches, access points and basic policies of internal traffic
- Internal Services: Shared Storage, IP Cameras, Multimedia Systems, Printers, Sensors and Control Panels
- Bandwidth management, traffic priorities, quality of service and limitation of use by users or zones
04
Internet on board, external communications and integration with satellite systems, 4G/5G and Marina
- External connectivity sources: Satellite, 4G/5G, port Wi-Fi, radio links and hybrid solutions
- Integration of external connectivity with the internal network of the ship through multi-wan and failover routers
- Coverage management, latency, speed, data consumption and availability according to navigation zone
- Prioritization of critical services against entertainment, streaming, guests and low-priority uses
- Secure remote access configuration for maintenance, technical support, monitoring and administration of the boat
05
Applied project of design and implementation of an internal network in boat
- Case definition: yacht, sailboat, small ship, tourist boat, work boat or recreational naval facility
- Analysis of needs: users, zones, connected systems, external Internet, security, entertainment and technical operation
- Network architecture design with equipment, cabling, Wi-Fi, segmentation, addressing and internal services
- Integration of external satellite, mobile or port connectivity with priority criteria, failover and consumption control
- Preparation of the cybersecurity plan, maintenance, documentation, diagnosis and failure recovery
