Overview
This page provides a description of the scenario used to support the SSPM workshop, the development of an Oil Separation, Storage and Transfer System (Oil SSTS) through the acquisition process. Be aware that this is a fictitious and hugely simplified scenario, developed solely for the SSPM workshops.
Participants may wish to review this information during the SSPM workshops to support their understanding. Page two includes generic information about the Oil Rig where the Oil SSTS will be installed.
Oil SSTS Scenario Description
Overview of Oil SSTS Requirement
To help rebuild a national state, the UK Government has decided the country should be supported in extracting their oil resources to provide an income and stability. Unusually the Frontline Command was asked to take responsibility for this action and has tasked DE&S to help design and develop the Oil SSTS.
Oil SSTS Overview
The Oil SSTS receives hydrocarbons direct from the well head into a separator which acts to remove gas which is to be released via a flame tower, water which is sent for further processing to enable use on the rig and sediment which settles out. The processed oil then passes to storage tanks or can be supplied direct to a tanker should one be waiting. Valves and a pump are used to direct flow to/from the storage capability. Metering of oil is used from storage to the tanker to provide indication of quantity passed to tanker.
This Oil SSTS shall:
- Meet the requirements of DSA01
- Have the capability to store separated oil between tanker transfers, complying with the Control of Pollution (Oil Storage) Regulations
- Be able to operate in all weather conditions prevalent in the region
- Be able to readily isolate the well and oil transfer system within 10 seconds
- Be able to receive crude oil from the extraction point of the rig, at pressures up to 20bar
- The system shall have the means to be operated continuously
- Be able to accurately meter for quality and quantity the transfer of oil to the tanker
- Comply with HSE Legislation
- The number of personnel to operate the system shall be minimised
- Be capable of separating out water, solid particles and gas from the crude oil
- Comply with the Control of Noise at Work Regulations
- The Oil Rig will be fitted with a fire detection and alarm system in all modules and on the open deck
Design level user requirements for the Oil SSTS include:
- Capability shall provide for extraction of crude oil from provided hydrocarbons (from well head)
- Capability shall provide for storage of crude oil
- Capability shall provide for transfer of crude oil to tanker
- Capability shall provide for measurement of offloaded oil (to tanker)
- Capability shall provide for continuous operations
- Capability should require minimum personnel to operate
