Completions & Commissioning oversight and execution support services

Completions and Commissioning oversight

OCCMS’ long standing relationship with Centrica Storage at their UK onshore Gas Processing & Storage terminal, was formed to provide Completions & Commissioning oversight and execution support services. The high-level summary of the scope requirements are as follows:

Execution oversight of handover from principal contractor

  • Commissioning Test Procedure development and implementation

  • FAT Support

  • Plan and execute pre-commissioning and dynamic commissioning

  • Technical delivery of processes and competence assessed personnel

  • Support handover to client operations for start-up and ongoing production

During this project, OCCMS have safely delivered commissioning and completions services for Phases 1 to 4 at our client’s UK based terminal which receives separate and condition natural gas and associated liquids from two separate offshore fields to meet the required specification before transfer of natural gas into the national transmission system (NTS). The processing facilities consisted of an inlet area/separation, onshore compression, dewpointing, filtration and fiscal metering with associated utility and auxiliary supplies. During the initial period, various brownfield modifications were undertaken within the onshore plant and included, but not limited to, F&G system modifications which were updated to accommodate the changes within the gas plant.

Following this initial phase, additional gas compression, additional F&G, and methanol recovery and injection facilities were upgraded and or modified as part of the new Humber Gathering System (HGS) and included upgrading receiving facilities for the new Tolmount offshore field.

All construction completions and commissioning execution was controlled and managed through OCCMS’ ORBIT completions management system on premise with a dedicated database administrator at the clients facility.

The total onshore hours expended on life of project, including a small proportion for senior leadership oversight, are ~60,000 without a lost time incident, including during the Covid 19 pandemic. “This strong track record is demonstrable of OCCMS’ strong safety leadership & inherently positive behaviours which are prevalent throughout all levels of management and delivery teams alike” stated OCCMS’ Operations Director – Jamie Japp.
