Sarnia

New (replacement) Multirole workboat for Guernsey Harbour Authorities.



ProjectProject to replace an existing multirole workboat with a new vessel, with extended capabilities by combating the working restrictions causing by existing machinery limitations with the previous vessel.
Details

The Boatbuilder required a full engine room package with reliability at the forefront of the selection process.

The tender stated the need for a bollard pull figure which lead us to Doosan’s new 4L126TIH engine with a continuous duty rating and providing a combined output of 900hp.

A requirement for an auxiliary engine that could provide power for electrical and hydraulic power which did not require seawater cooling provided us with the chance to showcase our in house set building capabilities. After discussions to understand the customers’ needs we were able to deliver a bespoke auxiliary set to meet the customer requirements without any compromise.

    • We have been dealing with Watermota for the past 4 years. In that time, they have been very helpful to us. The knowledge of the range of products they sell is amazing. Their staff are effecient and friendly and give great advice over the phone to the skipper doing repairs in port. When you order the items, the staff make sure that the parts get sent out fast, this means less "downtime" for skippers and crew. We would not hesitate to recommend Watermota main office in the UK or their dealer in Northern Ireland, Mr. Garry Brown.
    • We are a small workboat builder in Hythe Southampton building vessels from 10 to 24m. We have always fitted Doosan engines to our vessels due to the robust nature of the engines. Watermota are our local Doosan dealer and we are very impressed with the service we gain from them. Watermota work closely with us to make sure the engines we fit to our vessel are the most appropriate for the vessel. Even through the design stage of the build they are very helpful and willing to give us advice on how to make sure that the engines have what they need. The engines are delivered to us on time, and if for some reason there is a delay they keep us aware of the new date. At the end of the build they come on board to help commission the engines to make sure they are running correctly. The whole prosses is very easy for us. After we hand the vessels over to the clients, Watermota are always happy to help them solve issues.
    • We have the peace of mind that Watermota will do their very best to help us and always pull out all of the stops, Top quality service!
    • James from Watermota called me back to tell me that the part would leave within 30 minutes and be driven directly to the vessel, he provided all of the carrier details as well as a contact number for the delivery driver and double checked that I had all of the parts needed to complete the repair, right down to the last bolt. We had the vessel back in service that night, which was exactly what we needed.
    • I rang Watermota at 13:30 explaining that the vessel needed to be back in service by 6am the next morning and the part was urgently required. After speaking to the Sales team and explaining the importance of the contract they did everything they could to help, from taking the part off a stock engine to arranging same day transport.
    • Our company operates a fleet of commercial fishing vessels based in the the south west. We have always received excellent service support for our Doosan engines from Watermota, planned maintenance or unscheduled repairs are always dealt with quickly and efficiently.
    • Just thought I’d drop you an email to say how happy I am with my engine packages. I took fuel for the first time this evening and after calculating our miles covered we came to an average consumption of 3.25 litres per mile at a cruising speed of 15 knots at 1800 rpm. This is far better than we expected, our old engines only gave us a cruise of 12knts for the same consumption. We’ve gone from 6L 185hp to 8L 230hp engines making the boat gain speed and reliability but without an increase in fuel consumption. Coupled with the fantastic customer service throughout the process and huge list of extras included in the package, Watermota/Doosan certainly come out on top. With many plans for more boats in the future, unless another company can top that they will all be Doosan powered.
    • I would like to thank you and all the team at Watermota for your recent help with a very large order I received and with a short lead time to get it completed. From receiving quotes promptly to processing the orders and organizing direct delivery to my client in a small time frame Watermota were always on hand to help nothing was too much trouble.
    • We have been using Watermota to provide us with Doosan engines for several years and their level of service and support exceed expectations.
    • It’s been a pleasure doing business with you, you’re all on the ball and always reply to our queries quickly which is very much appreciated.
