Marine Surveyor (Tips to select them)

Marine surveyors are experts who evaluate and assess the condition of ships,
boats, and other maritime vessels. Their function is critical in guaranteeing vessel
safety and seaworthiness, and they are expected to maintain high ethical standards
in their work.

Below 6 important notes when selecting a marine surveyor to represent your interest:

  1. Marine surveyors must have the knowledge, skills, and expertise to carry out their jobs efficiently. They should also be conscious of their own limitations and seek advice or support when needed.
  2. Marine surveyors must maintain integrity and honesty in all of their dealings. They must not make false or misleading claims or engage in any action that jeopardizes their integrity.
  3. Marine surveyors have to keep a professional posture at all times. They should dress appropriately and speak effectively with clients, colleagues, and other survey participants.
  4. They should not be influenced by external considerations such as the vessel’s owner or operator, charterer, or any other entity with an interest in the vessel. Their opinions and suggestions should be based purely on the facts of the case, and any conflicts of interest should be avoided.
  5. Marine surveyors should put safety first in their work. They must identify any safety risks and adopt suitable prevention/mitigation actions. They should also be familiar with pertinent safety legislation and guidelines.
  6. Marine surveyors must keep their clients’ information confidential and should not release any information without the client’s permission or unless required by law.


Vessels with Ballast Water Treatment Systems installed and planned to sail to US waters, need to comply with both regulations.

  • US EPA VGP 2013
  • IMO BWM.2/Circ.70

Vessels sailing in US waters must comply with the US maritime regulations (EPA VGP 2013), just for the simple reason that the US is not a signatory of the Ballast Water Management (BWM) Convention.

In order to comply with the regulations, the discharge water from BWTS need to be tested in order to confirm Biological Efficacy, and that the system is operated in accordance with the standards and requirements.

By performing the discharge water testing the specialist ( can check the mechanical, physical, chemical and biological process of the BWTS, and compliance with regulations, It is recommended that the Sampling and Testing is performed by a independent test facility, accredited and certified to perform the tests required. See for more info.

24Marine will verify that your BWMS is operated in accordance with performance and standards at discharge as per USCG  and IMO.

Different type of systems (Chlorine, Ozone, Electrolytic, Ultraviolet, Pasteurization, etc) require different type of tests, sampling and check procedures.

When the test are performed by land based facility (Accredited Laboratory) it is really important to hire a specialist (trained) water sampling specialist, in order to collect, filed test, preserve, transport, document and deliver the samples to the lab following the standards. If the Sampling procedures are not followed by standards the sample can be declared as not valid.

Cargo Tanks – Drone Inspection

Drones and UAV offer a very real solution for the inspection of confined areas, such as tanks / cargo holds. Traditional inspection of these tanks is a laborious, expensive and poses many potential risks. The use of a drone revolutionises the time  needed and the the safety of cargo tanks and cargo holds inspection.

By performing tanks  and cargo holds inspections using drones the specialist ( can check the the real time conditions of places that are not accesible by normal human conditions.

A drone can be quickly deployed to capture images and video to allow asset inspectors to view all internal spaces. This includes fitting pipes, wall and bulkheads junctions, welding, structural members, without the need for workers to spend time in a highly hazardous environment,  workinng at high.

Industry statistics shows that 98% of the costs are related to HSE and preparation, only 2% to the inspection itself. By removing the need for staging, scaffolding, downtime and the time is taken for humans to enter confined spaces leads to a cost reduction that amounts to hundreds of thousands of dollars

Traditional cargo tank inspection takes days to implement. Tank inspections carried out by a drone can take as little as two hours per tank. or cargo hold.

Why to use ROVs?

Remotely Operated Vehicles, or ROVs, are submergeable robots that are controlled from above the water. ROVs are connected to the topside via cable umbilical (tether) cable and controlled using a joystick in a similar to play a video game. A group of cables, connects the ROV to surface station, sending electrical signals back and forth between the operator and the vehicle.

Here we summarize few of the benefits of using ROV for our underwater surveys:

Reducing Human Exposure:

Human divers can only submerge to certain depths for a restricted period of time, and the skill and danger involved makes deepwater diving unrealistic.

Reaching Deeper:

ROVs allow us to investigate areas that are too deep for humans (divers) to safely reach themselves.

Diving Longer:

Remote Operated Vehicles can stay underwater much longer than a human diver, expanding the time available for exploration. The only limitation will be the power source (battery or power supply).

Although ROVs were not as successful initially, the technology has come a long way, and now Underwater Vehicles are regularly used offshore for petroleum developments and drilling, fishfarming, military and oceanogrphy investigations.
