4D SCHEDULING

4D visualization is used on many different types of projects from offshore projects to land based

construction, shipyards, new builds, retrofit and overhauls of rigs, vessels

Utilization of a 3D model to link to a project schedule provides a unique visualization of the

project schedule sequencing of key events, milestones, tasks, build strategies and simultaneous

activities before you strike the first arc.

4D SCHEDULING

The level of detail is only constrained

by the amount of information that is

desired all the way down to the part

level. Animating the process flow to

simulate the movements of

assemblies and materials is common

for this format.

When used for BIM (Building Information Modeling) purposes, the

project can be sequenced on a yard-wide scale to coordinate and

validate assembly areas, process flows and materials staging.

4D SCHEDULING

For overhaul and retrofit projects where a 3D model may not be available, the critical areas can

be modeled to validate multi discipline concurrent activities in a constrained schedule

Concurrent hot work deck repairs and ballast tank coating safety validation

4D SCHEDULING

Some of the benefits of utilizing the 3D model link to the project schedule

Provides validation of the install sequence

Maximizes resource loading and minimizes task congestion

Provides efficient verification to follow on test and commissioning

Allows for real-time task progress updates to clearly see the impact to the overall schedule

4D SCHEDULING

A visual representation of the scheduled dry dock activities can be highlighted in several ways.

This sample uses a color code to represent the activities in the schedule to clearly see where the

they are taking place and also identify any integrity issues with the hull structure.
