11、 as defined in Subsection 1/5. Requirements for column-stabilized or self-elevating drilling tender units are addressed separately in the ABS Guide for Building and Classing Mobile Offshore Units (MOU Guide). This Guide addresses only the requirements specific to drilling tender barges. The ABS Rule
12、s for Building and Classing Steel Barges (Barge Rules) are to be complied with in addition to the requirements contained herein. 3 Classification The conditions of classification are contained in the separate, generic ABS Rules for Conditions of Classification (Part 1). 3.1 Notation Drilling tender
13、barges complying with the full requirements of this Guide will be classed and distinguished by the notation A1 Drilling Tender Barge. Barges complying with the ABS Guide for Building and Classing Accommodation Barges (Accommodation Barge Guide) may be assigned the classification A1 Drilling Tender,
14、Accommodation Barge. However, the actual assignment of the Accommodation Barge notation is optional for drilling tender barges. 5 Definitions Accommodation Block. Superstructures and deckhouses enclosing accommodations, including any overhanging decks supporting such accommodations. Drilling Tender
15、Barge. A barge fitted with facilities to carry persons that is principally intended as support to an offshore drilling unit. The barge is typically moored alongside the offshore unit during drilling operations and may contain the power supply, circulating pumps, storage tanks, drilling pipe racks, c
16、asing, cement, storage space, and helicopter landing platform. Hazardous Areas. An area where flammable or explosive gases, vapors, or dust are normally present or likely to be present. Short Field Moves. Repositioning of a barge during daylight up to 20 miles in distance or eight hours in duration.
17、 Transit Operations. Barge movements from one location to another that are not classified as short field moves. ABSGUIDE FOR BUILDING AND CLASSING DRILLING TENDER BARGES .2017 1 Section 1 General 7 Operating Manual An operating manual which is consistent with the information and criteria upon which
18、classification is based is to be placed aboard the drilling tender barge for the guidance of the operating personnel. Insofar as classification is concerned, the operating manual is to include, as appropriate, the following information: i) A general description of the barge, including major dimensio
19、ns, lightship characteristics ii) Summaries of approved transit and operation conditions including: Limiting environmental conditions, such as wave height and period, wind velocity, current velocity, and service temperature of the barge Design deck loadings, mooring loads, icing loads, variable load
20、, cranes, and types of helicopter for which the helideck is designed Disposition (open or closed) of watertight or weathertight closures Identification of “Restricted Service” or “Limited Service” conditions iii) Vessel Information: General arrangement drawing Location of hazardous areas Watertight
21、and weathertight boundaries, location of unprotected openings, and watertight and weathertight closures Type, location, and quantities of permanent ballast Allowable deck loads Capacity, centers of gravity, and free surface correction for each tank Hydrostatic curves or equivalent iv) Guidance for t
22、he maintenance of adequate stability and the use of the stability data v) Guidance for the routine recording of lightweight alterations vi) Guidance for the recommended sequence of emergency shut-downs vii) Examples of loading conditions for each mode of operation and instructions for developing oth
23、er acceptable loading conditions, including the vertical components of the forces in the anchor cables The Operating Manual shall be in the language or languages required by the flag State. If the language is not English, a translation into English is to be included and submitted to ABS. The Operati
24、ng Manual is to be submitted for review by the ABS solely to verify the presence of the above information which is to be consistent with the design information and limitations considered in the barges classification. ABS is not responsible for the operation of the barge. The Operating Manual require
25、d by this Subsection does not need to be in addition to that required by flag and coastal Administrations. The administration may require that additional information be included in the Operating Manual. 2 ABSGUIDE FOR BUILDING AND CLASSING DRILLING TENDER BARGES .2017 Section 2: Arrangement, Machine
26、ry and Systems SECTION 2 Arrangement, Machinery, and Systems 1 Stability In assessing the stability of drilling tender barges, the requirements in Section 6 of the Accommodation Barge Guide are to be complied with. When large cranes are permanently installed, the barge is to satisfy the intact stabi
27、lity requirements in 5-3-3/9 of the Barge Rules. 3 Pipe Racks Pipe racks, including the reinforcements for the hull, are to be designed to adequately resist the load effects of drill pipes or risers imposed on the pipe rack using the design load calculations in 5-3-4/5.5.2 of the Barge Rules, with t
28、he allowable stresses defined in 5-3-4/5.5.3 of the Barge Rules. Consideration should also be given to the barge in damaged conditions, where the pipe racks are to withstand the load effects caused by the trim and heel of the barge with a factor of safety of 1.0. 5 Hazardous Areas Drilling tender ba
29、rges may have permanent or temporary equipment on deck that creates hazardous areas. If any of the tenders intended modes of operation include hazardous equipment, arrangements are to be made to accommodate and operate such equipment safely. The area where such equipment will be installed is to be c
30、onsidered hazardous, and electrical equipment, ventilation, and access to adjacent spaces in this area are to be in accordance with 4-3/11 of the MOU Guide. Alternatively, if the area where temporary hazardous equipment will be installed is not in compliance with this Guide, a procedure for making t
31、his area suitable for such equipment is to be developed. 7 Mooring Equipment Owner requested position mooring equipment notations or position mooring system certification are to be in accordance with Section 10 of the Accommodation Barge Guide. 9 Piping System Segregation Piping systems carrying non
32、-hazardous fluids are to be segregated from piping systems which may contain hazardous fluids as per 4-2/1.3 of the MOU Guide. 11 Emergency Shutdown Arrangements Arrangements are to be provided for the shutdown of electrical equipment as per 4-3-5/7 of the ABS Rules for Building and Classing Mobile
33、Offshore Drilling Units (MODU Rules).

34、ith an applicable recognized standard need not be in accordance with this Guide or the Steel Vessel Rules, except where specifically stated in this Section or the Accommodation Barge Guide. Details of the recognized standard applied and how the equipment and components comply with the recognized sta
35、ndard are to be submitted for review. 13.1 CDS Notation (optional) Systems installed permanently on the barge that have been designed, reviewed and surveyed, in accordance with the ABS Guide for the Classification of Drilling Systems (CDS Guide), will be classed and distinguished in the Record with
36、the notation CDS. 13.3 Drilling Tender Barges without CDS Notation Where the optional CDS notation is not requested, drilling system equipment and components complying with an applicable recognized standard, need not to comply with the CDS Guide. Verification of compliance with such standards may in
37、clude: Surveyor verification of manufacturers affidavits of compliance, or equivalent documentation, mainly for equipment and components such as pumps, valves, fittings, or motors, Design review and surveys after installation of specific assembled systems or sub-systems such as high pressure mud and
38、 cement piping or hydraulic piping. The design review will be performed to verify compliance with the applicable recognized standard specified by the manufacturer. When equipment or components do not comply with an applicable recognized standard, the equipment or component is to be fully certified i
39、n accordance with the CDS Guide. 4 ABSGUIDE FOR BUILDING AND CLASSING DRILLING TENDER BARGES .2017 Section 3 : Fire Protection and Operation Safety SECTION 3 Fire Protection and Operation Safety 1 General Requirements In general, the level of safety requirements applied drilling tender barges is dep
40、ending on the number of people being carried onboard. 1.1 36 or More Persons Where a drilling tender barge is fitted with facilities to carry 36 or more persons, it is to comply with all of the requirements contained in Part 3, Chapter 5 of the Barge Rules. 1.3 Fewer Than 36 Persons Where a drilling
41、 tender barge is fitted with facilities to carry fewer than 36 persons, the requirements contained in Part 3, Chapter 5 of the Barge Rules are given special consideration, taking into account the length of the voyage, area of operation, number of persons onboard, and other relevant information. At a
42、 minimum, this will include consideration for the selection of materials for accommodations, service spaces and work spaces, fire-extinguishing equipment, electrical power supply, lifejackets, lifebuoys, survival craft, communications, etc. 3 Other Fire Protection Requirements In addition to the req
43、uirements in the above Subsection 3/1, drilling tender barges are to comply with the following requirements. 3.1 Passive Fire Protection of Accommodation Block The exterior boundary of an accommodation block is to be an “A-60” Class boundary for the whole of the portion that faces the adjacent drill
44、ing unit and is within 30 m (98 ft) of any area where a hydrocarbon fire may arise. If the distance is more than 30 m (98 ft), but less than 100 m (328 ft), an “A-0” Class boundary is required. Where an “A-60” Class boundary is required, an “A-0” Class boundary used in conjunction with a water curta
45、in system designed to provide a density of at least 6.1 liters/min/m2(0.15 gpm/ft2) of the exposed surface area may be used as an equivalent means of meeting the “A-60” Class rating. The ventilation inlets and outlets as well as other openings in the deckhouse and superstructure exterior boundaries
46、are to be located as far away from the adjacent drilling unit as practicable. 3.3 Active Fire Protection Systems and Equipment The active fire protection requirements of Part 5, Chapter 2 of the MODU Rules are to be apply; special consideration may be given taking into account the installed equipmen
