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.
Ship Energy Efficiency Management Plan (SEEMP) PART I
Regulation 26.1 of MARPOL Annex VI requires each ship of 400 gross tonnages and above, subject to Chapter 4 to keep on board a ship specific Ship Energy Efficiency Management Plan (SEEMP). The purpose of Part I of SEEMP is to establish a mechanism for a company and/or a ship to improve the energy efficiency and reduce the carbon intensity of a ship's operation. Preferably, this aspect of the ship-specific SEEMP is linked to a broader corporate energy management policy for the company that owns, operates or controls the ship, recognizing that no two shipping companies are the same, and that ships operate under a wide range of different conditions.
PART II OF THE SEEMP - SHIP FUEL OIL CONSUMPTION DATA COLLECTION PLAN
Regulation 26.1 of MARPOL Annex VI requires each ship of 400 gross tonnages and above, subject to Chapter 4 to keep on board a ship specific Ship Energy Efficiency Management Plan (SEEMP). The purpose of Part I of SEEMP is to establish a mechanism for a company and/or a ship to improve the energy efficiency and reduce the carbon intensity of a ship's operation. Preferably, this aspect of the ship-specific SEEMP is linked to a broader corporate energy management policy for the company that owns, operates or controls the ship, recognizing that no two shipping companies are the same, and that ships operate under a wide range of different conditions.
PART III OF THE SEEMP - SHIP OPERATIONAL CARBON INTENSITY PLAN
The Carbon Intensity Indicator (CII) is a rating system for ships that the International Maritime Organization (IMO) developed. This will be a mandatory measure under MARPOL Annex VI, which comes into force in 2023.
A brief description of NOX emission requirement
In this article, a brief explanation on the limiting requirements for NOx emissions from marine diesel engines is given and the three emission tiers are briefly reviewed.
Requirements within emission control areas (The latest amendment)
Refer to MARPOL Annex VI, Reg. 14, While a ship is operating within an emission control area, the Sulphur content of fuel oil used on board that ship shall not exceed 0.10% m/m.
In this article, we tried to collect the exact definitions of the SECA for our readers, as a reference.
Safety Investigation Report
Considering the importance of investigating accidents in preventing their recurrence, in this article we will discuss the incidents’ review including rout causes and correction actions. Stay with us.
Ammonia as a marine fuel
Ammonia has attracted wide interest as a source of zero emission fuel for shipping. Ammonia has the key benefit of being easier to store than hydrogen, i.e. nearly identical to propane (LPG) at low pressure under ambient conditions. Hence, the cost of storage per energy unit is significantly cheaper than either hydrogen, electricity in batteries or LNG.
