InsightsWritten to be used, not to rank.
Intervals, standards, selection criteria and the trade-offs nobody puts in a brochure. Every article here is written by people who specify and supply this equipment - including the parts where our own products are not the answer.
Twelve guides across the portfolio
Grouped by what you are trying to decide. If you want the shortest route to an answer, the selection tools get there faster than any article can. Product and range news, certifications and events are on News.
ROV or diver? How the economics actually compare
The published savings figures are real but conditional. Here is the version you can put in a business case without it falling apart under questioning.

UWILD surveys: what they cover and when an ROV can do one
Two bottom surveys in five years, what the video has to show, and the conditions under which class will accept an ROV instead of a diver.

Choosing an inspection ROV: five questions that actually matter
Depth is the first thing people ask and rarely the deciding factor. These five questions are the ones that change the answer.
Read the guide →
Needle scaler, deck scaler or blasting?
Three methods, three different jobs. Choosing by area, access and substrate rather than by what is already in the store.
Read the guide →
Hand-arm vibration: what the limits mean for tool choice
The daily exposure limit is not a paperwork exercise - it decides how many hours a crew member can legally spend on a scaler.
Read the guide →
Fire suppression cylinders: what SOLAS actually requires
Where the requirement comes from, how often it applies, and why weighing a cylinder is not the same as knowing it is full.
Read the guide →
Hatch cover testing: ultrasonics, hose test or chalk?
Three methods for the same question. Only one of them tells you where the leak path actually is.

Repairing GRE pipe in place
Glass-reinforced epoxy cannot be welded. What that leaves you with, and the four-coat build-up that works.
Read the guide →
Why epoxy repairs fail, and the eight steps that stop it
Almost never the product. Chlorides, profile and dew point account for most of it, and all three are measurable.
Read the guide →
Sonar or camera? Specifying for water you cannot see through
Below about a metre of visibility, camera specification stops mattering and acoustics become the primary sensor.
Read the guide →
Compressed air leaks: finding them and costing them
A leak survey that produces a list gets ignored. A leak survey that produces a cost gets funded.
Read the guide →
Building a daily net inspection programme
Escape prevention is a frequency problem, not a technology problem. What it takes to inspect daily rather than quarterly.
Read the guide →Where each of these leads
Every guide connects to the part of the catalogue it is about. That is deliberate - an article that cannot point at anything was not worth writing.
Underwater robotics
UWILD, ROV selection, sonar versus camera, the diver comparison, net inspection.
Marine Robotics →Repair & coating
GRE pipe repair and the surface preparation that decides whether any of it lasts.
Epoxy Solutions →Tools & instruments
Scaling versus blasting, vibration exposure, ultrasonic testing, leak detection.
Tools & Equipment →Applications reference
The wider library - applications by industry, enabling technology and documented deployments.
Knowledge Center →Or just describe the problem
If you would rather skip the guide and get an answer, that is what we are for. Tell us what is wrong and we will specify it.
