Introduction to Inert Gas Systems (IGS)
Inert gas system is the most important integrated system for oil tankers for safe operation of the ship. Inert gas is the gas which contains insufficient oxygen (normally less than 8 %) to suppress combustion of flammable hydrocarbon gases.
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.
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.
Bunker Delivery Note (BDN)
According to Regulation 18 of Annex VI of the MARPOL Convention, all ships with a gross tonnage of 400 and more that receive consumable fuel (for burning in internal combustion engines) must take a document called "Bunker Delivery Note" and keep it onboard for at least 3 years. In this article, we give a brief explanation about BDN.
Oil Record Book
This is necessary in order for authorities to be able to monitor if a vessel’s crew has performed any illegal oil discharge at sea. All officers and crew onboard need to recognize that recording of ORB is required by the rules and the records are critical.
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.
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.
