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.
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.
Case Studies for using Advanced NDT in Oil & Gas Industries
Non-destructive Testing (NDT) consists of a variety of non-invasive inspection techniques used commonly for mechanical equipment, structures, and piping systems to locate and determine the defect features such as size, shape, and orientation.
In this article, we tried to collect different cases and provide summary status of technique used by worldwide companies.
Requirement of standard discharge connections for Sludge & Sewage
Both oil residues (sludge) and sewages collected on board must be delivered to the reception facilities, regularly.
In this regard, there are two types of standard discharge connections. This article mentions the specifications and requirements of this connections based on the MARPOL Convention.
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.
Introduction to Pressure Safety Valve
The primary purpose of a pressure safety valve is the protection of life, property and environment during an over-pressure event in a pressurized vessel or equipment. An over-pressure event refers to any condition which would cause pressure in a vessel or system to increase beyond the specified design pressure or maximum allowable working pressure.
Corrosion protection of cargo oil tanks of crude oil tankers
Crude oil is a complex mixture of substances at varying ratios and in most cases contains at least some salt water. Even after desalination some of this brine remains dissolved in the crude and gradually sinks to the bottom of the cargo oil tank during transport. The corrosive nature of salt, along with microorganisms and other aggressive substances contained in the cargo oil, causes rust, most notably in the form of pitting, which are cavities in the steel that deepen over time.
Crankcase Relief Valve
SOLAS regulations to prevent crankcase explosions came into place after a particularly devastative explosion that claimed the lives of 28 people onboard MV Reina Del Pacifico in 1947.
Since then, many detection and preventive measures have been added to ships to eliminate or at least reduce the risk of this phenomenon. In this article, we shall take a look at what crankcase explosion is, how it occurs and what can be done to prevent it.
The MARPOL requirements of oil residues (sludge) tanks
In accordance with MARPOL/Annex I/Reg. 12, ships with a gross tonnage of 400 and above are mandated to be equipped with a tank or tanks of sufficient capacity. The capacity should be determined with consideration given to the type of machinery and the duration of the voyage, ensuring the proper reception of oil residues (sludge).
