SOLAS II-1/3-13 Amendments:
Electronic Inclinometers Required

The International Maritime Organization (IMO) has finalized critical safety amendments. Starting January 1, 2026, bulk carriers and container ships must integrate advanced heel-monitoring technology to prevent stability-related catastrophes.

Core Regulation Requirements

Applicability

Mandatory for all Bulk Carriers and Container Ships of 3,000 GT and above.

Installation

Electronic inclinometers must be fitted on the navigation bridge for continuous real-time monitoring of heel and roll.

Compliance Date

Existing ships must meet requirements at the first renewal survey on or after 1 January 2026.

Safety Rationale & Enforcement

Following high-profile accidents involving cargo shifts and capsizing, the IMO Maritime Safety Committee (MSC) prioritized better operational awareness. The goal is to provide Bridge Officers with precise, recorded data to detect dangerous rolling patterns early and prevent stability loss.

Practical Compliance Guide

  • Retrofitting: Shipowners should audit current bridge equipment and plan for inclinometer installation well before the 2026 deadline.
  • Data Integration: Ensure the device records data for safety analysis and incident investigation as per IMO standards.
  • Training: Navigating officers must be trained to interpret real-time heel/roll data to adjust navigation in heavy weather.
  • Certification: Devices must be type-approved by a Recognized Organization (RO).
Mariner's Pro-Tip: Don't just install it—calibrate it! Regularly verify the inclinometer against your vessel's stability software to ensure total accuracy during heavy cargo operations.

Safety first: This article is educational guidance, not a replacement for the vessel’s Muster List, emergency instructions, Safety Management System, lifejacket label or Master’s orders. In a real emergency, raise the alarm, follow your assigned station and obey the crew. Do not launch a survival craft or jump into the water unless instructed and the situation requires it. The alarm sounds during the night watch. For one second, the person who has just joined the vessel may not know whether it is a drill, a machinery alarm or the beginning of a real emergency.
