SPECIFICATION · MARINE BoP

One crew-sized
HUD.

Crews shrink while plants grow more complex. The answer cannot be another screen; it has to be one picture that tells a small watch team what needs attention.

DESIGN TARGET · NOT MEASURED PERFORMANCE

Figures on this page are engineering design targets and reference-architecture values, not measured results from operating hardware. They state what the design is being engineered to achieve. Verified performance data will replace them as systems are built and tested. Nothing here should be relied upon as a performance warranty.

Design basis
CONSOLIDATION

Fuse, do not add

Each new vendor system arrives with its own HMI. Consolidation means the watch monitors the plant rather than the procurement history.

ALARMS

Rationalised and contextual

A thousand nuisance alarms is equivalent to none. Priority, suppression, and context are specified per IEC/ISA alarm-management practice.

TRAINING

Learnable in a rotation

A watchstander rotates aboard and must reach competence quickly. Time-to-competence is an explicit design requirement.

HUMAN FACTORS

Designed for fatigue

The interface is designed to be usable by a tired person at 0300, because that is when it will matter most.

Standards basis

Alarm management follows recognised industry practice (ISA-18.2 / IEC 62682 principles). Human-factors design follows established control-room ergonomics guidance. Conformance is design intent and would be validated during acceptance.
