What is offshore vessel drydock planning software?

Plan offshore vessel drydocking from work scope and specifications through execution, progress tracking, completion and documented project history.

Offshore vessel drydock planning software helps operators organise and manage the work required before, during and after a vessel drydocking.

A drydock project can bring together planned maintenance, outstanding technical work, inspections, repairs, equipment overhauls and vessel modifications within a limited project period. For offshore support vessels, the scope may also involve specialised propulsion, deck and offshore equipment depending on vessel type and configuration.

Rather than managing these activities through disconnected spreadsheets, documents and maintenance records, drydock planning software provides a structured environment for developing the work scope, preparing specifications, planning project activities, following execution and documenting completed work.

The core process is:

maintenance needs and findings → drydock scope → work specification → planning → execution → progress and changes → completion → drydock history

Developing the drydock scope

Effective drydock planning begins before the vessel enters the yard.

Maintenance history, outstanding technical work, inspection findings and known equipment requirements can all contribute to the initial work scope.

Bringing these requirements together helps technical teams build a more complete picture of the work that should be considered during the docking period.

For an offshore support vessel, the scope can include work across hull and structural areas, propulsion machinery, thrusters, deck equipment and other specialised systems depending on the vessel's configuration and applicable requirements.

From work list to drydock specification

Once the initial scope has been identified, individual work items need to be organised into a clear drydock specification.

The specification describes the work to be considered and provides a common structure for planning the project.

Individual items can be associated with relevant vessel systems and equipment so that the project remains connected to the vessel's wider technical environment.

Previous maintenance and drydock records can also provide useful context when defining new work, particularly where equipment has a history of repairs, recurring issues or previous modifications.

Planning the drydock project

A drydock combines many technical activities within the same project period.

Planning therefore involves more than identifying what work needs to be completed. Technical teams also need to organise the scope, priorities and sequence of work while preparing for the resources and information required during execution.

A structured drydock environment gives the project team a common view of the planned work before the vessel enters the yard.

This helps create continuity between day-to-day vessel maintenance and the larger package of work being prepared for drydocking.

Yard and quotation preparation

A structured drydock specification can also support communication with shipyards and other external parties involved in the project.

Using a consistent work scope makes it easier to communicate the technical requirements of individual jobs and evaluate how proposed work relates to the original specification.

For offshore vessels, this can be particularly useful where the scope includes specialised machinery or equipment that requires appropriate technical capability from the selected yard or service provider.

The software supports the organisation of the project information; commercial tendering and contracting processes remain subject to the operator's own procedures and systems.

Managing work during drydocking

The drydock scope can continue to develop after execution begins.

Inspections or dismantling may reveal additional work, while existing jobs can change as more information becomes available.

A structured project environment helps teams maintain visibility of the original scope, work in progress, additional findings and completed activities.

Keeping these changes connected to the relevant work items makes it easier to understand how the final project differs from the original plan.

Connecting drydock and maintenance

Drydocking and day-to-day maintenance are closely related.

Offshore CMMS software manages planned and corrective maintenance around vessel equipment. Some of that work may later become part of a drydock scope when it is more appropriately performed during a docking period.

Similarly, work completed during drydocking can become part of the technical history associated with the relevant vessel equipment.

Connecting these processes helps preserve continuity between maintenance before the docking, project work in the yard and maintenance after the vessel returns to operation.

Documenting completed drydock work

Completion is not only about finishing the physical work.

Technical teams also need a reliable record of what was actually performed during the project.

Completed work, supporting documentation, images and other relevant technical information can contribute to the final drydock record.

This creates a documented project history that can support future maintenance and provide useful reference material when the next docking period is planned.

Drydocking as part of the asset lifecycle

Major drydock projects can also represent important points in the lifecycle of vessel assets.

Equipment may be overhauled, repaired, replaced or modified during the docking period, creating technical information that remains relevant long after the project has finished.

Offshore support vessel EAM takes the broader lifecycle perspective by connecting this technical history with the physical assets being managed over time.

Drydock planning focuses on the individual docking project; EAM preserves the longer-term asset perspective around the equipment affected by that work.

How STAR Suite™ supports offshore vessel drydock planning

STAR Suite™ supports project and docking activities alongside day-to-day vessel maintenance.

Maintenance information can contribute to drydock preparation, while project activities can be organised around the technical work being planned and performed. Checklists, images and supporting documentation can provide additional context around individual activities and completed work.

By keeping maintenance and docking activities within the wider vessel management environment, technical teams can maintain greater continuity between routine maintenance, drydock preparation, project execution and the resulting technical history.
