Tenders
15th May 2020
General situation:
Upon arrival at the Yacht both tenders were found to be located in their normal position on the forward mooring deck. Both of the tenders had protective exterior covers fitted and were secured to the deck by their respective lashings, fore and aft.
Information Provided ahead of Survey:
In conversations with the crew and several pictures that were shared prior to our arrival, it was relayed that the Yachts tenders have sustained damage, due mainly to wave action during the Yachts recent transatlantic crossing.
Both tenders suffered electrical, structural and engine/auxiliary equipment failures. The extent of the damages is very well documented in the attached reports which were generated by LB Tenders. Essentially, it has been reported that as a direct consequence of the damages sustained, both tenders were unusable.
The engines on each tender were, for the most part, submerged by seawater. The crew reports that the engines were not started at any stage. Any and all information including the work reports have been provided by the Captain. It is also reported verbally that a sum exceeding 136K Euros has been spent on the repair works.
Starboard Side Tender:
In brief terms, anything that was under the deck sole, which has any form of electrical component has been replaced for new. That includes electrical connectors, batteries, starters, relays, engine harness etc. Mechanically, what can be fully restored to an “as new” state, has been done so. Where the parts concerned couldn’t be fully restored, they have been replaced for new.
All of these works were conducted under the yacht crew’s direction and supervision. The scope of works was generated by LB tenders, executed by LB Tenders and reported upon by LB Tenders. No independent assessment appears to have been carried out. The works (on both tenders) appears to have been executed well. The Captain reports that the tender manufactures were in direct consultation with the LB Tenders repair team.
What should be noted; as you can see in the report, the scope or outlined works were mainly concerned with only repairing the damage caused by the incident. There are several knock-on-effects of those works that have resulted in the replacement or refurbishment of other non-connected equipment(s).
There does remain a collection of recommendations that are detailed below; we have limited these to what we would consider to be any differences between the survey conducted in St. Martin and the present state, post works, or as a result of the damage. What is not included is and should be considered as general wear and tear (as seen in St. Martin).
Underwater seawater intake scoop is crushed and not sealed well to the hull. This should be removed, replaced for new.
Battery terminals have no covers fitted. Rubber boots should be fitted to all onboard exposed terminals.
Hairline cracks noted on swimming platform port side. These should be investigated to ensure no structural issues are underlying. Conclusion not-withstanding repairs should be carried out.
The hull has several areas of scrapes and chips out of the black antifouling. The hull should be repaired where the chips are located and a new protective antifouling system applied.
Bow thruster power terminals are missing connecting covers. Fit these covers to protect the connecting terminals.
The hull has several areas of scrapes and chips out of the black antifouling. The hull should be repaired where the chips are located and a new protective antifouling system applied.
Tear on port side leather side fender cushion. Repaired to be effected.
Port Side (Rescue) Tender:
The same method of repair has been followed through on this tender as the other. The main difference between the two is that this tender has suffered more GRP damage. Much of the extra works have gone into the these repairs. As before, the reports attached show the details and extent of the damage, along with the rectifying actions taken. These works appear to have been executed well.
The self-righting actuating bottle is now out of date and will need tone removed, serviced and hydro-tested. The relevant certification should also be provided.
Battery selector switch is loose in the console forward section. This selector should be properly secured with rear mounting plate.
Metal securing plate or fitting next to the turbocharger support bracket appears to have been hastily modified and fitted. This fitting should be replaced, the aft end is failing.
Forward facing seat securings have been ripped out and the seat no longer secures. These fittings should be made good to prevent the seat from flying off during navigation.
Batteries have missing protective coves or rubber boots. These should be fitted.
Corroded rear coupling. This should be removed, corrosion cleaned, protective coating applied and re-fitted.
Forward facing seat securings have been ripped out and the seat no longer secures. These fittings should be made good to prevent the seat from flying off during navigation.
Console repairs starboard side have not been executed very well. Recommend finishing works are redone. (
Sea Trials:
Both tenders were launched, sea trialed and then recovered onboard. The tenders were run around the waters of the Genoa basin in moderate sea state conditions. Both of the tenders ran well, with no problems noted in both engine performance of general handling characteristics.
All lights, electronic equipment, bilge pumps, trim tabs, engine trims, throttle controls, VHF Radio’s, stereo and speakers were all tested and operations proven.
Tender Chocking System:
As a result of the forces (mainly vertically downwards it is assumed) due to wave action and compounding deck lashing forces, the following is noted. The starboard side chocking system has been little affected. There are no signs of stress or material deformation.
The port side chocking system does show signs of the above. Pictures were also provided by a crew member, some of which as shown below. It is apparent that the chocking system has undergone some repair works. It is not clear how these were executed and to what standards of testing they have measured against.
Pictures after incident below.
The repairs have not (aesthetically at least) been executed to a high standard. They may well be strong enough to be stated as “fit for purpose” but the finishing is poor in some areas. The below pictures are the current conditions.
Yacht’s Deck Structure:
The tender’s deck lashing system appears to remain unaffected by damage. The pad eyes (where fitting) are in sound condition.
The deck it’s self was inspected from top side and also from the technical space below deck. A calibrated audio gauge was used verify deck thickness’s in various accessible locations (machine details: GL:1296035 with measuring range 1.2 - 225mm and accuracy +- 0.1mm). All measurements are consistent with manufacturing class approved drawings.
No visible signs of deformation, material failure or overhead buckling were noted. Nor were there signs of any transversal or longitudinal structural or stress related issues.
