MARINE-GRADE · VLAN SEGMENTED

Structure Below Deck. Control Above It.

A vessel's internal network is the backbone of its digital operations. Oceanifi designs and installs marine-grade structured cabling systems and VLAN-segmented architectures that enforce strict boundaries between operational and crew traffic — with zero interference and full QoS policy enforcement.

Built Tough. Built Right.

Marine-Grade Structured Cabling

Cat6A and fiber optic cabling systems specified for marine environments — salt-air resistant jacketing, watertight penetration glands, and UV-resistant conduit throughout. Every run documented with a full as-built cable schedule.

Industrial Managed Switches

DIN-rail and rack-mounted industrial switches from Cisco IE and Hirschmann — rated for extended temperature ranges (-40°C to +75°C), high shock/vibration (IEC 60068), and EMI environments typical in engine rooms.

VLAN Architecture & Segmentation

Strict layer-3 VLAN separation ensures complete isolation between OT/Bridge systems, Business/Admin networks, and Crew/Welfare traffic. No cross-contamination, no broadcast storms, no unauthorized lateral movement.

Network Monitoring & Management

Remote SNMP monitoring, syslog aggregation, and centralized management via cloud-based NMS. Full visibility into switch port utilization, link errors, and bandwidth consumption — accessible from shore 24/7.

From Survey to
Go-Live in 4 Steps.

Every Oceanifi infrastructure deployment follows a rigorous 4-stage process — minimizing vessel downtime while maximizing the quality of the final installation.

01

Vessel Survey & Design

On-site audit of existing cabling, equipment spaces, and network requirements. Full AutoCAD network design delivered within 7 days.

02

Material Procurement

Marine-grade hardware sourced and kitted. All components pre-tested in our workshop before shipment to minimize time on-vessel.

03

Installation & Configuration

Certified technicians complete the installation during port call or dry-dock. All VLAN, QoS and security policies configured and tested.

04

Handover & Documentation

Full as-built documentation, VLAN diagrams, and remote monitoring onboarding. Crew handover training included.
