Hazardex 2019 Conference Presentations - EI Not Permanently Attended Installation Guidelines

Author : James Jenkins - Principal Consultant, DNV GL

19 November 2018

In June 2010 the Energy Institute issued the first edition of the Not Permanently Attended Installation (NPAI) guidelines. The document sought to provide best practice guidance on issues of safety, welfare and the environment consistent with optimising the benefits of NPAI’s for the international petroleum industry. The EI and DNV GL have recently revised the NPAI Guidelines to more accurately reflect current international best practice.

The focus of the guidance is on two principals:

a) To maintain and where possible, improve, safety through identification and adoption of industry best practice; and

b) Address where costs savings, production optimisation and enhancement can be realised which are consistent with safe and environmentally responsible operation.

Increasingly operators, through improved connectivity and plant control have explored possibility to remotely operate geographically disparate plants from a central control room. The themes and topics within the NPAI guidelines would be applicable to these onshore operations as points for consideration should an operator design, inherit or retro-fit such a remote manning philosophy.

The NPAI guidelines cover the lifecycle of an installation and focuses on describing the process that the reader should adopt to reach the most suitable design or operation for their NPAI. Throughout the guidance there is a clear theme that processes should be examined on a risk basis over the lifecycle of the NPAI taking account the balance between major accident risks (safety and environmental), travel risks, welfare issues and operational factors.

The topics that a presentation will cover are:

• Design of remotely operated installations;

• Transition from normally manned to remotely operated installations (and vice-versa); and

• Operation of remotely operated installations.

Each topic will look at several key themes that are important to consider with remote operations:

• staffing demand versus the productive hours;

• benefit of safety systems versus the risk exposure associated with maintaining them;

• simplification/minimisation whilst providing adequate welfare provision;

• safety management;

• environmental aspects;

• reliability/availability;

• maintenance strategies;

• asset integrity;

• changing production profiles; and

• legislative compliance.

 

With over 100 NPAI’s and numerous NPAI operators within the UK Continental Shelf, the NPAI guidelines are a distillation of the learning from these operations which attendees should find informative, insightful and useful.
