The underwater inspection is a scheduled or unscheduled inspection, but necessary due to the certain circumstances, expertise of risks. The underwater survey of the ship’s hull state is a procedure which is required for each ship irrespectively of her type and cargo-carrying capacity. The underwater survey is necessary for estimation of the general and detailed technical state of the ship’s hull underwater part before docking, purchase or sale of the ship as well as a compulsory part of a package of measures approved by the Classification societies
In most cases the ship’s underwater inspection is carried out under supervision of the Classification society inspector, and the diving companies performing the inspection are pre-tested for competence in a required Classification society and have its recognition at the hands for performing the works as to surveying the ships.
By using a professional underwater inspection service, you can find a wide variety of potential issues that may slowly be damaging your ship. Bent or damaged propeller blades, hull corrosion and cracks, leaking thruster seals, damaged rudders, obstructed sea chests and many more common issues can be identified immediately. By completing a thorough inspection, the dive team provides an intensive report that outlines all the issues with the vessel and the possible fixes.
These reports allow ship owners to understand the true condition of their vessel, which lets them decide whether or not they immediately want to repair the problem. In almost all cases, it is recommended that the repairs be done as soon as possible, as they only worsen with time and can lead to safety issues, expensive repairs and the ship being out of commission for weeks
Underwater inspection in lieu of dry docking (UWILD)
Damages after grounding or collisions with other vessels
Evaluation of Vessel’s technical condition before purchase, sale or rent.
Fouling and coat evaluation in order to prepare ship for docking
Obtain/renew a license of vessel for operation
Survey of the vessel can be performed in the harbors anchorages. It is necessary to have a special permit to perform this type of work. Therefore, an underwater inspection of the vessel is carried out by a team of specially trained divers with necessary equipment.
During the vessel surveys system of underwater television (CCTV) is used, it allows to broadcast the underwater images on monitor in real time regime.
The results are entered into the diving report and transmitted to the ship owner along with a photo and video recording of the work after the examination.
A full written diving report and copy of video and/or colour still photographs are submitted after the survey to vessel master and the classification society’s marine surveyor.
