Undersea Cable Editing and Proofreading Services

A consortium's cable is damaged by an anchor drag in a shallow crossing. The repair ship needs the permit to work in that jurisdiction's waters, and the application requires the exact route position list for the segment. The as-laid position list on file was never reconciled against the route the ship actually laid after a mid-installation diversion around a newly designated protected area. The permit stalls while the discrepancy is resolved, and traffic stays on a restoration path at reduced capacity for eleven additional days.

We edit what undersea cable projects produce — route position lists and as-laid documentation, marine survey and desktop study reports, permit and licence applications for territorial and coastal waters, cable landing licence submissions, construction and maintenance agreements, repair and maintenance authority documentation, environmental impact and protected-area assessments, consortium and supply contracts, and landing station and terminal documentation. Our editors work on the position list a repair ship needs to be right about years later.

The as-laid route position list is what every future permit, repair, and survey is worked from, and its failure is a document that still records the route as planned rather than the route as actually laid. We work through these so every position reflects what the ship actually laid, with any diversion from the planned route recorded as its own entry with the reason and date, since a list that quietly carries planned coordinates forward sends a repair vessel to the wrong place under time pressure; so the coordinate datum and format are stated explicitly on the document itself, given that positions transcribed between datums without conversion land kilometres from the cable and the error is invisible until someone is on station looking for it; so slack, burial depth and protection status are recorded per segment as actually achieved rather than as specified, because a repair plan built on assumed burial in a section that was surface-laid is planning the wrong operation; so the jurisdictional boundaries each segment crosses are identified against the position list, since the permit a repair depends on is determined by exactly which waters the fault falls in; and so what was not surveyed or verified is stated plainly, given that a gap presented as a confirmed position is the specific failure that turns an eleven-day repair into something longer. Documentation written this way is still correct when a ship is waiting on it.

Everything you send is treated in confidence, including route data, survey results and consortium documentation. We are editors rather than marine engineers, hydrographic surveyors or permitting specialists, and we offer no view on route determinations, survey data or operational decisions. What we can do is make sure the record describes the cable that was actually laid.
