A Vessel Warranty Surveyor provides independent third-party technical review and approval to any marine vehicle or structure, It is crucial to include surveyors from the planning stages through to the physical execution.
You will get:
Independent and impartial advice.
Review, approval, and attendance for location surveys in accordance with regulations, standards, and best practices.
Condition and suitability surveys for a wide range of vessels.

Rigging surveyor job is to check and review the key components of the boat system to ensure that is fit for purpose.
In general, a Rigging system survey has three objectives:
Check that the system has been regularly inspected and serviced.
Check the states of the sails
Check that the rigging is less than 10 years old.
Regular service periods:
The regular service period is calculated by Insurance companies, flag states, Cost guard, and standards organizations, based on FATIGUE LOAD CYCLE of the rigging. The statistical data shows that rigging failure rates are higher after 10 years.
The picture below shows how a load cycle in the normal operating range, due to the large numbers of such cycles can cause cumulative damage to the material.
The 5 years inspection needs to be done with the mast un-stepped, as it is impossible to check key components (Terminal, plates, buckles, wires, stays, etc.) with the rigging fully un-assembled. Also, NDT (nondestructive Test) as a penetrant liquid test need to complete with the system on the floor.
The 10-year rigging checks need to be completed with all rigging wires replaced, due to the FATIGUE LOAD CYCLES, which normally cause Cracks, deformations that affect the structural properties of the rigging system.
See the video below where you can see many comon failures we have colledted during years of rigging surveys.
The list below shows the most common issues found after rigging collapses:
Terminal and fittings failures
Turn Buckle failures
Mast deformations
Chain Plates failures
Stays (wire) failures
Rod heads
Below few notes from the Rigging experts:
Keep your rigging clear of corrosion, ALWAYS
Regularly check tension on stays
Never remove safety pins from Turnbuckles
Recommended to use Split pins.
Never replace only one side Stays or Shroud, the other side (older) will be a weak link.
If replacing a stay, is recommended to replace the associated turnbuckles.
Bring mast down every 5 years for inspection, if needed perform NDT (Nondestructive test)
Bring mast down every 10 years for inspection and ALL rigging components replacement.
The US Coast Guard published a Marine Safety Alert 07-09, call SAILBOAT RIGGING DANGER, you can download on the link below, has many useful information and tips for any sailor.
Very often we get asked about boat surveys and what are the benefits of doing so, this week we are going to discuss details on the importance of marine surveys.
What is a Marine Survey?
it is a comprehensive check-up for boats, designed to identify existing problems, point out areas to improve, and give a detailed picture of the overall health of the vessel.
The two major reasons to hire a Marine Surveyor are:
1 Get an Unbiassed Assessment
When you are buying a boat, especially second-hand, the current owner may not be aware of any existing problems, if there is any, This is when a marine survey is very important before settlement.
During a repurchase survey the marine surveyor has the opportunity to assess all aspects of the vessel:
Structural
Mechanical Components
Rigging
Plumbing
Electrical Systems
Hull Planking
Propulsion System
As a result, the surveyor submits a report, with recommendations and a conclusion, that can help the price negotiation and repairs needed.
2 Get Profesional Valuation
Many marine underwriters (insurers), require a complete survey to be completed prior they will ensure a pre-owned vessel.
A professional marine surveyor will inform whether any repair needed to be completed and the cost of each repair accurately, this information is vital and can be used to determine if the boat is a good value and what is estimated provision in years ahead for upkeep.
Buying a boat is a big step, and a huge investment, a Surveyor will be your best advisor during this process.
Now days most survey tasks involve robots that are designed in such way that they remove human intervention from labour intensive and hazardous work environment.
Sometimes they are also used to inspect inaccessible spaces / confines places which are generally impossible to access by humans.
Many pipes comes in the dangerous spaces because they carry toxic chemicals, fluids and most of the time has small internal diameter or bends which become inaccessible to human.
The complex internal geometry and hazard content constraints of pipes demand robots for inspection of such pipes in order to check corrosion level of pipe, recovery of usable parts from pipe interior, sampling of sludge and scale formation on pipe internal surface etc
In 24 Marine we have developed a Pipe Robot that ensure you are getting a pipe survey cost effective and reducing human exposure. we have developed virtual reality pipe inspection, that bring your pipes to real life.
El principal objetivo de toda investigación consiste en identificar las causas de los siniestros, con la finalidad de poder emitir recomendaciones tendentes a evitar que vuelvan a suceder. Nunca se ha de tratar de buscar culpabilidades.
Asimismo, resulta de máxima importancia la cooperación y colaboración de todas las partes involucradas, Armadores, Dueños de buques, Estados Ribereños, Estados de Abanderamiento, Gente de mar, etc. con la finalidad de garantizar la trasparencia y veracidad de la información obtenida y, con ella, poder esclarecer las verdaderas causas del incidente.
