Originally built in 2012, our swim-ended, rectangular, flat top deck cargo barge Isabella S began life working predominately working at the Forth bridge construction project. Deployed as a long term crane barge platform and complimented with 4 x 25t anchor handling winches, along with the setup of 5 tonne stockless anchors to allow for the precise positioning required for the project.

Having completed work at the Forth Bridge, Isabella S was purchased by Jenkins Marine in May 2020 with conversion work carried out in October 2020 at ABP Falmouth. This work was mainly to remove the anchor winches and install 2 new spudleg pockets for our 36” x 24m spudlegs. This has allowed the barge to work in sheltered near shore water projects with the consideration of tidal ranges or tidal current flows where an anchor spread solution would be ineffective.

Following the conversion work the vessel went directly to its first project where it was instrumental in acting as a large crane platform for the £50M redevelopment of the Thanckes Oil Fuel Depot. The facility provides fuelling facilities for the Royal Navy at Devonport Naval Base. This large project was overseen by Volker Stevin, working for the Defence Infrastructure Organisation on behalf of MOD.

On completion of the project the barge went back into drydock in Swansea for Bureau Veritas 5 year class and load line renewal surveys, and at the same time we have implemented a vessel name change from Isabella S to the JML 6022. The drydocking has also allowed us to perform a high pressure wash and to paint the barge throughout including adding our distinctive branding, all of which has transformed its appearance!

JML 6022 is certified through Bureau Veritas for Unrestricted Navigation. It is 60m x 22m x 4m flat top pontoon barge and can act as a transportation barge for goods or as a crane barge to support large crawler cranes with its 15t/m² deck strength along its centre line.
