Ban on Use of Anti-Fouling Systems Containing Cybutryne
At its seventy-first session in July 2017, MEPC approved a new output to amend Annex 1 to the AFS Convention to include controls on cybutryne. While work on this matter is ongoing in the Sub-Committee on Pollution Prevention and Response (PPR), the scientific data presented so far indicates that cybutryne causes significant adverse effects to the environment, especially to aquatic ecosystems.
Shipboard Testing of Ballast Water Management Systems
Shipboard Testing is a full-scale test of a complete BWMS carried out on board a ship according to IMO Guidelines, to confirm that the system meets the standards set by regulation D-2 of the Convention.
In this article, we try to express the shipboard testing as the final step in receiving the type approval certificate by taking the IMO guidelines.
The maintenance and inspections for fixed carbon dioxide fire-extinguishing systems
Fixed gas fire-extinguishing systems generally work by either lowering the oxygen concentration in the surrounding atmosphere to a level where combustion becomes impossible or by disrupting the essential chemical reactions needed for the fire to continue spreading.
Understanding UMA (UMS) Ships and Their Operational Requirements
UMA (Unattended Machinery Area) ships, sometimes referred to as UMS, are designed for machinery and equipment operation without constant watch-keeping personnel. This article outlines the specific machinery included, stringent safety requirements, and the need for meticulous ship design. It emphasizes fire safety measures, prevention of flooding, alarm systems, and communication means, all crucial for ensuring safe and continuous operation.
Anchor Windlass Design and Testing (IACS 2018 Requirement)
A windlass used for handling anchors, suitable for the size of chain cable and complying with the Classification Society’s criteria is to be fitted to the ship. The design, construction and testing of windlasses are to conform to an acceptable standard or code of practice. To be considered acceptable, the standard or code of practice is to specify criteria for stresses, performance and testing.
Sampling point in the ballast water discharge line
In accordance with article 9 of the Convention, a Party may sample the ship’s ballast water for the purpose of determining whether the ship is in compliance with the Convention in accordance with these Guidelines. Although the Convention contains no requirements for provision of sampling points, the Guidelines for approval of ballast water management systems (G8) adopted by resolution MEPC. 174(58) do expressly call for the provision of sampling facilities, not only for the purpose of type approval, but also for the purpose of other required sampling process.
