The vision for the future in the oil and gas industry is to develop installations that are unmanned, digitalised, fully automated, remotely overseen and monitored by humans. In this context, both topside and subsea infrastructure, including operation, drilling and well services, will support autonomous operations by using artificial intelligence, digitalisation, drones, and robots. All logistics on sea and interfaces to the field will cater to autonomous vessels, overseen and monitored remotely in centralised centres, which handles multiple assets and fields, in different locations.
The easy answer is: "Because it is a statutory requirement". An Alarm Philosophy has to follow specific standards, and in a court of law you could be held accountable for not applying the standards to your alarm system design. However, there is more than the legal aspect to it. The Alarm Philosophy exists for operational, safety, work environmental, design and behaviour reasons - and ultimately, cost effectiveness.
