Refer to the MEPC 76, some amendments on MARPOL annex VI and technical guidelines in relation to the operational carbon intensity indicator (CII) annual rating scheme adopted.
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.

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.
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.
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.
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.
The Engine International Air Pollution Prevention Certificate (EIAPP Certificate) plays a pivotal role in addressing Nitrogen Oxide (NOx) emissions from marine engines. This certification, governed by the NOx Technical Code, employs prescribed test cycles and measurement methods to calculate NOx emissions, emphasizing compliance with stringent environmental standards.
The efforts to launch the world’s largest zero-emission sailing cargo ship took a step forward with the announcement that a Canadian coffee company is investing in the project.
