Review ship drawings across owners, yards, engineers and suppliers

Put marine comments where they apply

A lot of ship drawing feedback makes little sense without the drawing in front of you. “Move this valve”, “check access here”, “equipment differs from the general arrangement” or “route to be confirmed” all depend on location.

A reviewer can place the markup directly on the relevant area and attach the explanation to it. Anyone responding to the comment sees the same part of the drawing. That is much easier than asking the engineering team to match a spreadsheet row to a position on a busy arrangement drawing.

Give different organisations one review to work from

Marine projects often involve owners, yards, naval architects, engineering companies, suppliers and subcontractors. They may all have good internal systems, but the boundary between companies is where drawing comments often fall back to email and PDF attachments. Xenmark helps at that boundary. The review runs in the browser, so the owner can comment on a drawing prepared by the engineer, or the yard can add practical input without everyone needing the same desktop software.

The aim is not to replace each company’s document system. It is to give the shared drawing review a clearer home.

Use it during newbuilds, conversions and modifications

The same review pattern appears in different types of marine work. On a newbuild, the yard, owner and engineering team may be reviewing a drawing before construction. During a conversion, several disciplines may need to coordinate changes around an existing arrangement. On an operational vessel, the crew may identify that an older drawing no longer matches what is physically on board.

In each case, a marked-up PDF can be the common starting point for the discussion.

Keep owner comments and engineering replies together

An owner comment is often not a simple instruction.

The engineer may need more information. The yard may explain why the proposed change is difficult. A supplier may need to confirm equipment data. The owner may then accept an alternative.

That conversation can stretch over several days. If it lives in email, the final decision can be hard to connect back to the exact drawing issue later.

In Xenmark, the replies stay with the original markup. The location, request and response history remain together.

Track open points without maintaining another manual list

Marine drawing reviews can contain a lot of small comments alongside a few major ones. Some are fixed quickly. Some depend on another supplier. Some remain open into the next revision.

Statuses make it possible to keep those differences visible. Instead of reading through every annotation before a meeting, the project team can see which review points still need attention and open the discussion only where it matters.

Keep earlier comments useful when the next revision arrives

Ship drawings often go through several issues. The latest PDF tells you what the drawing looks like now, but it may not tell you why something changed. The previous review does. Keeping comments and replies around the revision cycle gives the owner, yard and engineer a better record of what was requested and what still needs to be checked.

It also makes it easier for somebody who was not part of the first review round to understand the background.

Common marine review workflows

Export comments when the project needs a separate record

Drawing comment sheets and spreadsheets are still common in marine projects. Xenmark can export the comments to Excel when a standalone register is needed for handover, reporting or exchange with another organisation, together with a comment plan PDF showing each numbered comment on the drawing. That lets the project team use a shared review without forcing every downstream participant to change the format they work with.

How Xenmark fits alongside class and document control

Marine projects can have formal approval, class, flag and document-control requirements. Those processes remain where they are. Xenmark is for the working review around the drawing: owner comments, engineering responses, yard feedback, supplier questions and checks of revised issues.

If a drawing later needs to be submitted through a class-society portal or another controlled process, that still happens through the required channel. Xenmark helps get the drawing and the comments into a clearer state before or between those formal steps.
