Recovery of persons from the water
Refer to the SOLAS 2012 Amend / Chapter III / Reg. 17-1, all ships shall have ship-specific plans and procedures for recovery of persons from the water, taking into account the guidelines developed by the Organization. (MSC.1/Circ.1447)
Ballast Water Management Convention
Following the UN Conference on Environment and Development (UNCED), held in Rio de Janeiro in 1992, the IMO initiated negotiations to consider the possibilities of developing an internationally binding instrument to address the transfer of harmful aquatic organisms and pathogens in ships’ ballast water. From 1999 onwards, the Ballast Water Working Group, established by the MEPC in 1994, focused on the preparation of a free-standing Convention on control and management of ships’ ballast water and sediments. Finally, on the basis on these measures, The BWM convention adopted in 2004.
Commissioning Testing of Ballast Water Management System
The purpose of commissioning testing is to validate the installation of a ballast water management system (BWMS) by demonstrating that its mechanical, physical, chemical and biological processes are working properly.
Commissioning testing is not intended to validate the design of type-approved BWMS that are approved by the Administration. This article is prepared based on the 2020 Guidance for the commissioning testing of ballast water management systems.
What's new with SOLAS 2024
SOLAS 2024 amendments, that driven by MSC 105, and which will take into effect on 1st Jan. 2024, contains the changes that have been adopted for the 2024 update of SOLAS and its associated Codes. A set of amendments to SOLAS and the associated Codes has been brake down for earlier pre-notation within maritime sector.
Oil Mist Detector
A device that measures the oil mist concentration by inserting an oil mist detector into the crankcase of a marine engine. The sensor converts the measured mist concentration into an electronic signal and sends it to the monitor. If the mist concentration exceeds a certain value, an alarm will be issued.
Water Ingress Detectors in Bulk Carriers
Bulk carriers are renowned for sinking fast particularly if loaded with heavy cargoes such as iron ore. Possibility of ingress of sea water into cargo holds poses potential threat to ships. Masters of bulk carriers should be aware that the purpose of the Water Ingress Monitor (WIM) is to provide the maximum possible early warning of a condition that may seriously threaten the vessel's survival.
What are the Effects of Underwater Noise Pollution?
In the ocean, many marine mammals and other species rely on their hearing for survival. Sound is critical for communication, navigation, locating prey, avoiding predators and finding mates.
Ocean noise from ships and other human activity is increasingly impacting our marine life. In this article, the effects of underwater noise pollution have been considered and some solutions will be proposed.
Reducing underwater noise from commercial shipping
Concern has been raised that a significant portion of the underwater noise generated by human activity may be related to commercial shipping. The international community recognizes that underwater-radiated noise from commercial ships may have both short and long-term negative consequences on marine life, especially marine mammals.
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.
