A GUIDE TO THE UNIFIED TECHNICAL FILE — REGULATIONS FOR THE PREVENTION OF AIR POLLUTION FROM SHIPS

This booklet is designed for Licensees, ship operators, shipyards, and marine engineers in general, to illustrate the Unified Technical File created for all MAN B&W engines, which is necessary to comply with the IMO regulation aimed at preventing air pollution.

The Unified Technical File serves as a document that outlines a procedure, primarily based on performance measurements, enabling the operator to confirm adherence to the IMO ‘NOx Technical Code’ to the Flag State Authority or their representative when the engine undergoes checks in service. MAN B&W Diesel has developed this booklet to partly elucidate survey procedures and partly serve as a reference manual for IMO definitions.

The initial section focuses on survey routines, from the testbed to the onboard situation, which is crucial for the operator, detailing the survey process from beginning to end. The subsequent section delves into specific topics and how to manage the most common tasks onboard, such as the spare or reconditioning parts addressed by the regulation. For general emission inquiries or emission control of MAN B&W two-stroke engines, references are made to existing materials published by MAN B&W Diesel.

Many of the initial Technical Files created by engine builders differed due to the varying requirements imposed by different classification societies. This variation occurred because the IMO Annex VI does not provide sufficiently detailed guidance on how to compile the Technical File in practice. MAN B&W Diesel has taken on the responsibility of coordinating efforts to prepare a standardized Technical File, intended for use by both licensees and classification societies. This responsibility also encompasses the necessary procedures for shipowners when subsequent engine adjustments or component changes take place.

SHIP INFORMATION QUESTIONNAIRE FOR GAS CARRIERS

The objective of this questionnaire is to establish a standardized approach for collecting information about ships intended for the use of owners, operators, and charterers of vessels that transport liquefied gases in bulk, as well as for the terminals that handle such ships.

The phrase "Liquefied Gas Carrier" refers to vessels specifically engineered for the transportation of pressurized or refrigerated liquefied petroleum and chemical gases that possess a vapor pressure greater than 2.8 bar absolute at a temperature of 37.8°C, along with other products detailed in chapter 19 of the IGC Code, when transported in bulk, including those chemical carriers authorized for the transport of LPG and chemical gases.

While many owners already supply a ship information questionnaire, this document offers a suitable alternative where one is not available. The use of this questionnaire is entirely at the discretion of individual ship owners, operators, charterers, terminal operators, and other relevant parties.

It is anticipated that the Questionnaire will be completed in full only once during the lifespan of a ship, with minor adjustments to the recorded data being made as necessary should management, systems, or equipment undergo changes. Throughout the Questionnaire, if alternative responses are presented in the text, the response that does not apply should be removed.

OIL RECORD BOOK CODE GUIDE

As we are all aware, the shipboard ORB, standing for the Oil Record Book, is the formal document, providing the official evidence of compliance of the ship with the relevant requirement and instructions, outlined in the MARPOL Oil Pollution Prevention Annex I. That is the main reason why the responsible personnel shall possess clear understanding and knowledge of how the entries shall be made to the Oil Record Book of their vessel.

The present guidebook is there to provide brief explanation of the nice codes that are normally use when recording the oil operations, supplemented with the real examples of their application. For instance, the Code A is dealing with the ballasting/fuel oil tank cleaning activities, that shall be duly recorded in the ship's Oil Record Book with proper identification of the ballasted tanks, and information related to the cleaning and ballasting processes, while the Code B addresses the dirty ballast discharge. In short, one has to know how to fill and maintain the ORB at all times.

MODE CODE 2009 INCLUDING 2020 AMENDMENTS

This is the most important document released by the IMO in connection with the Mobile Offshore Drilling Unit safety. This document of 2009 has been amended several times to include the IMO Resolutions adopted after 2009. The present publication contains all amendments up to and including those of 2022 and is the current version of the Code.

The arrangement of the content is pretty traditional for the IMO MODU Code – the first section provides general information on the purpose of this regulatory document, its application areas and definitions used throughout the text, survey and certification requirements etc. The second section of the Code deals with the construction of the Units, the hull strength and materials used for construction.

The third section is devoted to the stability and freeboard including the hull subdivision and watertight integrity requirements. After that there are requirements concerning the machinery installations including boilers, propulsion machinery for self-propelled drilling units, elevating systems installed on jack-up rigs, hull systems etc.

the electrical installations are dealt with in a separate section, followed with the one on the hazardous area classification and associated requirements. The rest of the volume addresses such the critical aspects as fire safety, lifesaving equipment and systems, radiocommunication equipment, cargo gear, operational aspects, chopper facilities and, finally, the air test appliances used in the confined spaces.

BALLAST WATER CONTINGENCY MEASURES FOR TANKERS

The main content of the present publication developed and officially published by Intertanko, is arranged in four main sections. The first section of the document addresses the Ballast Water Management Convention itself, providing some historical background and highlighting the important reporting related aspects.

The authors underlined the expectations of each involved party, including company DPS, Flag State, Classification Societies, as well as the manufacturers of the ballast water management systems installed on board ships. The second section is entirely devoted to the regulations by the USCG, standing for the United States Coast Guard.

The third section covers the contingency measures, including such critical matters as repair of the shipboard ballast water management systems at the loading port and at sea, different options for the ballast water exchange, mid-ocean exchange both with and without the use of the system, mobile treatment facilities and associated equipment, partial discharges and others.

Finally, the closing section and the two annexes contain all necessary reporting forms and a sample repair plan for the ballast water management system.

EFFECTIVE MOORING

We are all aware of the fact that mooring is deservedly considered one of the most difficult and hazardous activities for both ship crew members engaged in the subject operation and the port workers. Should something go not as planned, this can eventually result in disastrous consequences.

The present publication was compiled by the professionals of the world respected OCIMF entity with the intention to provide industry with the general and concise introduction to the mooring operation, and also to give necessary guidance on provision of safety.

The style of the text is very easy to follow so the publication can be used for the training of the seafarers at all levels, starting with the very beginners. Note that this fourth release of the title is aligned with the Mooring Equipment Guidelines and you are encouraged to use both volumes, since the latter will provide even more detailed overview of the design of the shipboard mooring systems and their proper technical maintenance.

The main emphasis has been made by the authors on the crew activities and due attention has been paid to the human factor, considering the huge number of cases where this factor played the key role – note that most of them could actually have been prevented.
