Tug fleet management software is a digital platform that gives port operators, harbour towage companies and offshore tug operators centralised control over the maintenance, compliance and operational records of every vessel in their fleet. It replaces vessel-by-vessel paper logs and disconnected spreadsheets with a structured, shared system where technical managers on shore can see the full maintenance and certificate status of every tug at any time.
Tug operations place distinctive demands on a fleet management system. Harbour tugs work in high-cycle patterns — multiple short jobs per day, intensive main engine and propulsion use, brief intervals between assignments. Unlike deep-sea vessels with predictable voyage schedules, a harbour tug’s maintenance window is measured in hours, not days. Fleet management software that does not reflect this operational rhythm will produce schedules that look logical on paper but cannot be executed without taking vessels out of service at commercially critical moments.
A purpose-built tug fleet management platform handles maintenance scheduling based on engine running hours rather than calendar time alone — because a tug used intensively in a busy port accumulates engine hours at a fundamentally different rate than one on standby in a quieter terminal. Certificate tracking covers class certificates, flag state statutory documents, crew STCW qualifications and ISM documentation across every vessel in the fleet. Incident and non-conformity management captures safety observations, near misses and findings in a structured format that supports ISM audits without requiring a separate reporting system.
Fleet standardisation is where tug fleet management software delivers compounding value. When every vessel in the fleet shares the same equipment hierarchy, the same maintenance task library and the same documentation format, the fleet manager’s oversight is genuinely comparable across vessels — making it possible to benchmark maintenance completion rates, identify recurring defects across vessel classes and optimise spare parts procurement across the fleet rather than vessel by vessel.
The International Safety Management Code applies to tug operators running vessels on international voyages and to domestic fleets that have adopted ISM as a standard of practice. For harbour towage companies operating fleets of 5, 10 or 20 tugs, the administrative overhead of maintaining ISM-compliant documentation manually is substantial — and the risk of gaps appearing across a large fleet of high-cycle vessels is significant. Fleet management software that integrates ISM documentation with day-to-day maintenance and operations removes the separation between operational records and compliance records that creates audit risk.
Harbour tugs carry fewer certificates than large deep-sea vessels, but managing them across a fleet of 10 or 20 vessels creates its own complexity. Class renewal surveys, safety equipment certificates, liferaft service records, radio certificates, officer licences and crew medical records all have independent expiry dates that must be tracked against a continuous operations schedule. A single lapsed certificate on a harbour tug can ground the vessel at exactly the moment port operations need maximum towage capacity — during a heavy weather berthing, a large vessel arrival or a scheduled dry dock entry.
STAR Suite™ is built for the operational realities of maritime fleets, including the high-cycle, running hours-driven maintenance patterns of harbour and offshore tug operations. Fleet managers have real-time visibility across every vessel — maintenance status, certificate expiry and open non-conformities — from a single shore-based platform, while crew on board use the same system to record completed jobs and operational data during their shifts.
