QUESTION #4:

For work item (134) there are extensive material lists that are not clear as to what is required.

· DWG 8713677 METAL OUTFIT MATERIAL: ITEM #11 LPHRVFWD012-7787620-A1-38-38 MACPAC #87-06201 CALL FOR A TRI PAD WITH ALIGNMENT MARKS; DWG 8713678 METAL OUTFIT MATERIAL: ITEM #13 LPHRVFWD012-7787620-A1-51-51 MACPAC #87-06202 CALL FOR A TRI PAD WITH ALIGNMENT MARKS as two examples. We believe they are the pads for the pipe hanger angles. Please clarify what this is and what alignment marks are required and how to apply them. Also, if they need to be cut in the configuration depicted on 388-8713685 dimensions or auto cad drawings would be needed. Please provide same. .

ANSWER:

The stated question made reference to DWG 8713677, item #11 and DWG 8713678 item #13 being associated with material item object number LPHRVFWD012. To clarify, it should be noted that item #13 on DWG 8713678 is actually associated with a range of other object numbers (i.e. LFDNVAFT012 through LPHRVAFT082) vice LPHRVFWD012. DWG 8713677 Item #11 is correctly associated with object LPHRVFWD012.

MSC confirms that these material item objects are the pads for pipe hangers. The alignment marks refer to notches on the pads used by some shipyards to simplify production by marrying these notches on a pre-fabricated pipe hanger to pre-located alignment pins/studs on the deck or bulkhead. The “guidance only” Metal Outfit Fabrication Drawing 8713685 (e.g. SH25 for item object LPHRVFWD012 for example) is available for clarification. However, these details are provided strictly for guidance and the shipyard is not required to utilize alignment marks with the pipe hanger angle pads.

The configuration and size of the mounting pads can be in accordance with customary shipyard standards and practices. Drawing 388-8713685 is for guidance only.

QUESTION #5

QUESTION #10

Work item 203- Reference T9233-CF-IMC-070 has not been found in the reference files provided.

Please provide the reference?

The list of hoses provided in the work item, paragraph 3.3.1, table 203B-1 contain Fairbanks Morse Engines part numbers only. Fairbanks Morse Engines has not provided a quotation for the hoses. In order to determine hose, fittings and lengths of each unit, additional information is necessary. Please provide sufficient information to obtain quotations from other than Fairbanks Morse Engines?

Late word from Fairbanks Morse Engines is that there is an issue with Long Lead Time Material, although they did not indicate how long. We recommend that MSC purchase the hose assemblies directly from Fairbanks Morse Engines to eliminate the Long Lead Time Material issues as well as cut costs

ANSWER

Reference 2.1 added to List of References.

Source Hampton Rubber (identified in Work Item) is known to have developed a cross-over list for the T-AKE MDG Fluid Flex Connectors part numbers.

Preface

Characteristics of engines, justified expectations, pre requisites

Purpose of the operating and work instructions

Condition 1

Condition 2

Condition 3

Engines produced by MAN B&W Diesel AG have evolved from periods of continuous, successful research and development work.

They satisfy high standards or performance and have ample redundancy of withstanding adverse or detrimental influences.

However, to meet ali the requirements of practical service, they have to be used to purpose and serviced properly. Only with these prerequisites can unrestricted efficiency and long useful life be expected.

The operating instructions as well as the working instructions (working cards) are thought to assist you in becoming familiar with the engine and the equipment. They are also thought to provide answers to questions that may turn up later on, and to serve as guidance in your activities of engine operation, checking and servicing. Furthermore, we attach importance to familiarizing you with the functions, relations, causes and consequences, and to conveying the empirical knowledge we have. Not the least, in providing the technical documentation including the operating and working instructions, we comply with our legal duty of warning the user of the hazards which can be caused by the engine or its components - in spite of a high level of development and much constructive efforts - or which an inappropriate or wrong use of our products involve.

The technical management and also the persons in'charge of servicing works (possibly on order) have to be familiar with the operating instructions and working instructions (work cards). These should all times be available.

•• Cautionl Missing information and disregard for information can cause injury to persons, damage to property and the environment.

Please read the operating and working instructions.

The servicing and overhaul of modern four-stroke engines will in each case require previous training of the personnel in charge. The level of knowledge that is acquired during such training is a prerequisite to using the operating instructions and working instructions (work cards). No warranty claims can be derived from the fact that a corresponding note is missing in these.

•• Caution! Untrained persons can cause injury to persons, damage to property and the environment.

Never give orders, which may exceed the level of knowledge and experience. Access must be denied to unauthorized personnel.

The technical documentation is valid for one certain order only. There can be considerable differences to other plants. Information valid in one case can lead to problems in others.

• Attentionl Technical documents are valid for one certain order only. Using information of another order or from foreign sources can lead to disturbances/damages.

Only use the correct information, never use information from foreign sources.

1.2

To be observed as well ... Please observe also the notes on product liability given in the following section and the introduction passages and safety regulations in Section 3.

1.3

Product Liability 1.2

The reliable and economically efficient operation of a propulsion system requires that the operator have a comprehensive knowledge.

Similarly, proper performance can only then be restored by maintenance or repair work if such work is done by qualified specialists with the adequate expertise and skill. Rules of good workmanship have to be observed, negligence is to be avoided.

This Technical Documentation complements these faculties by specific information, and draws the attention to existing dangers and to the safety regulations in force. Fairbanks Morse asks you to observe the following:

...... Caution! Neglect of the…
