Section 1 General

101. Application

1. The requirements in notation specified in

this Chapter apply to the process systems installed in the unit with Process

Ch 2. For the process systems installed in the unit without process notation,

safety related requirements of this Chapter including facility layout, safety system, process shutdown

systems apply.

2. The requirements in this Chapter apply to facilities which are only installed on the unit and the boundary between process systems and other onboard systems are as the following:

(1) from the first inlet flange of the well fluid flow line above the water level inboard for import systems

(2) to the flange connected with the inlet flange of the storage tank.

3. The process system consists of the following equipment.

(1) Gas treatment systems for removal of the acid gases(hydrogen sulfide, carbon dioxide, etc.), de- hydration and removal of mercury from raw gas prior to liquefaction

(3) Liquefaction systems for liquefying the treated gas

102. General

1. In general, the design of process fied in Ch 11, Sec 2 and Sec

systems and equipment are to comply with the requirement speci-

3 of Guidance for Floating Production Units. In addition, for

the items which are not specified in this Chapter, systems which are in direct contact with lique-

fied gas or liquefied gas vapor are to be designed for compliance with the requirements of Pt 7, Ch 5, Sec 5 of Rules for Classification of Steel Ships.

2. Hydrocarbon processing systems and associated equipment are to be designed to minimize the risk of hazards to personnel and property caused by potential threats to safety, with considering the fol- lowings:

(1) Prevent an abnormal condition from causing an upset condition

(2) Prevent an upset condition from causing a release of hydrocarbons

(3) Safely collect and dispose of hydrocarbon gasses and vapors released

(4) Prevent formation of explosive mixtures

(5) Prevent ignition of flammable liquids or gases and vapors released

(6) Limit exposure of personnel to fire hazards

3. Structure that supports process facilities or forms an integral part of the equipment is to be de- signed to a recognized standard. Plans and calculations are to be submitted for the Society review. Process liquid weights and dynamic loads due to installation motions and other loads, such as wind imposed loads, are to be considered.

102. Codes and standards

1. The requirements not specified in this Chapter are to be international standards.

2. The following standards may be adequately referred standards.

in accordance with recognized national or as recognized national or international

104. Definition

1. Gas treatment is well.

a process in which impurities is removed from the produced raw gas from the

2. Fractionation is a separation process in which a mixture of treated gas is divided into LNG, LPG, condensate, etc.

105. Design conditions

The process systems are to be designed to account for all applicable environmental, operational, and test loads, or combination thereof. These include the following:

1. Environmental Conditions

(1) Earthquake

(2) Wind Ice

(3) Ice

(4) Temperature

(5) Current, waves

(6) 1, 10, 50, 100 year storm event, as applicable

2. Operational

(1) Static pressure

(2) Vibration

(3) Transient pressure excursion

(4) Acceleration loads due to movement of installation

(5) Temperature excursion

(6) Fluid static head and properties

(7) Tension

(8) Bending

3. Transportation

4. Installation

5. Commissioning

6. Test loads

106. Classification survey during construction

1. Submission of plans and documents
