2、 Northchase Drive Houston, TX 77060 USA Foreword Foreword Power vessels are power plants installed on marine or offshore vessels (e.g., barges, ships, offshore installations, mobile offshore units, and converted vessels) that offer a quick and economic method of providing power to remote locations.
3、To meet the increasing global demand, this Guide has been developed to provide requirements on design, construction, and survey for class review and approval of power vessels. This Guide is for the use of designers, builders, owners, and operators and specifies ABS requirements for obtaining the cla
4、ssification notation Power Service. This Guide is applicable to power barges, power ships, power offshore installations (OI), power mobile offshore units (MOU), which includes self-elevating units (SEU) and column-stabilized units (CSU), and power converted vessels. Power vessels can be equipped wit
5、h single or multiple gas turbines, reciprocating diesel or gas engines, or boilers for power generation. In this Guide, the requirements of the power generation and distribution equipment installed on board are associated with an optional notation. Design and installation requirements for power gene
6、ration and distribution equipment included in this Guide are based on existing industry practices that are deemed to provide an adequate level of safety. The application of this Guide by ABS will not prevent the use of technological approaches that can demonstrate an acceptable level of safety. Powe
7、r generation and distribution equipment designed, constructed, and installed in accordance with the requirements of this Guide on an ABS classed vessel, barge, offshore installation, or mobile offshore unit, under ABS review and survey, will be classed and identified in the Record by the optional no
8、tation null Power Plant. This Guide is to be used in conjunction with other Rules published by ABS and recognized international Regulations. This Guide becomes effective on the first day of the month of publication. Users are advised to check periodically on the ABS website www.eagle.org to verify t
9、hat this version of this Guide is the most current. We welcome your feedback.

17、tion 1 Classification The requirements for conditions of classification are contained in the separate, generic ABS Rules for Conditions of Classification (Part 1) and ABS Rules for Conditions of Classification Offshore Units and Structures (Part 1). Additional requirements specific to power vessels
18、including power barges, power ships, power offshore installations, power mobile offshore units, and power converted vessels are contained within this Guide. 3 Application This Guide covers new construction of power vessels including power barges, power ships, power offshore installations, and power
19、mobile offshore units as defined in Subsection 1/9. This Guide has been developed for classification requirements specific to design, construction, and survey of power vessels. The following base ABS Rule sets, as applicable for the vessels base Class notation, apply in full for design, construction
20、, and survey of the vessel, except as modified herein: The ABS Rules for Building and Classing Steel Barges (Barge Rules) are to be complied with for power barges intended for ocean service, as applicable. The ABS Rules for Building and Classing Steel Vessels for Service on Rivers and Intracoastal W
21、aterways (River Rules) are to be complied with for power barges intended for river service, as applicable. The ABS Rules for Building and Classing Steel Vessels (Steel Vessel Rules) are to be complied with for power ships, as applicable. The ABS Rules for Building and Classing Offshore Installations
22、 (Offshore Installations Rules) are to be complied with for fixed power offshore installations, as applicable. The ABS Rules for Building and Classing Floating Production Installations (FPI Rules) are to be complied with for floating power offshore installations, as applicable. The ABS Guide for Bui
23、lding and Classing Mobile Offshore Units (MOU Guide) is to be complied with for power mobile offshore units including self-elevating units (SEU) and column-stabilized units (CSU), as applicable. The ABS Guide for Floating Offshore Liquefied Gas Terminal (FLGT Guide) is to be complied with for gas po
24、wer vessel offshore terminals utilizing stored liquefied gas, as applicable. This Guide is also applicable for the conversion of existing vessels. Applicable base ABS Rules are to be complied with for power converted vessels. This Guide has also been developed to provide requirements for the design,
25、 construction, installation, and survey of power generation and distribution equipment on power vessels. 5 Class Notations 5.1 New Construction Power vessels complying with the full requirements in Sections 1 to 4 and 6 in this Guide may be classed and distinguished in the Record by adding the class
26、ification notation Power Service. The vessels will maintain their base rule notations such as barge, floating offshore installation, etc. For example, null A1 Barge, Power Service for ocean power barges; null A1 Barge, River Service, Power Service for river power barges. ABSGUIDE FOR POWER SERVICE F
27、OR MARINE AND OFFSHORE APPLICATIONS .2017 1 Section 1 Scope and Conditions of Classification If the power vessel uses LNG or LPG as a fuel source and is in compliance with Subsection 3/5, an optional notation (LNG) or (LPG) may be added to the notation. Power generation and distribution equipment, s
28、ystems, subsystems, and components that have been built, installed, and commissioned to the satisfaction of the Surveyors to the full requirements in Sections 5 and 6 of this Guide, where approved and reviewed by the Committee, may be classed and distinguished in the ABS Record by the optional notat
29、ion null Power Plant. Note: The mark null (Maltese-Cross) signifies that the vessel or system was built, installed, and commissioned to the satisfaction of the ABS Surveyors. 5.3 Conversion of Existing Vessels When an existing vessel is converted to a power vessel and it complies with the full requi
30、rements in Sections 1 to 4, and 6 of this Guide, it may be distinguished in the Record by adding the classification notation Power Service. The primary class notation should reflect the base rule set notation for the conversion. For example, if an existing drillship is converted into a power vessel,
31、 the base rule set, the FPI Rules, is to be applied for this conversion and it would possess the notation null Floating Offshore Installation (Ship-Type) (CI), Power Service. 7 Submission of Plans For the Power Service class notation, plans and documents specified in Sections 1 to 4 and 6, together
32、with supporting calculations, as appropriate, are to be submitted before proceeding with the work. For the optional class notation Power Plant, the submission of design plans and data is specified in Sections 5 and 6. Plans are generally to be submitted electronically to ABS. However, hard copies wi
33、ll also be accepted. 7.1 Materials This Guide is intended for power vessels designed and constructed of steels having properties as specified in the ABS Rules for Materials and Welding (Part 2). The use of steel or other materials that have properties different from those specified in the ABS Rules
34、for Materials and Welding (Part 2) and the corresponding scantlings are subject to special consideration. Where the power plant is fueled by natural gas the materials used in liquefied natural gas (LNG) tanks, gas piping, process pressure vessels, and other components in contact with cryogenic liqui
35、ds or gases are to be suitable for the intended purpose and in compliance with Section 5C-13-7 of the Steel Vessel Rules. 7.3 Stability, Loading, and Operating Information Information is to be submitted on ballast, fuel, supplies and hold arrangement and capacities; summary and distribution of fixed
36、 and variable weights for each reviewed condition; and information on all loaded and ballasted conditions in which the power barge, ship, floating offshore installation, or mobile offshore unit may be operated. In accordance with the requirements contained in Subsection 2/3, stability calculations d
37、emonstrating that the power barge, ship, floating offshore installation, or mobile offshore unit meets the stability criteria in all loading and ballast conditions are to be submitted for review. Information is to be submitted for intended operating location and any specific requirements based on ap
38、plicable local/national codes and standards for review. 2 ABSGUIDE FOR POWER SERVICE FOR MARINE AND OFFSHORE APPLICATIONS .2017 Section 1 Scope and Conditions of Classification 9 Definitions Power Vessel.
