With the official delivery of the 38 meter multipurpose workboat KRATT to the Estonian State Fleet (Riigilaevastik), a new benchmark for low-emission public sector vessels has entered Baltic waters. Built by Baltic Workboats, KRATT replaces single-purpose state vessels with a single, highly adaptable platform. Conoship International delivered the engineering scope for the project, covering the basic design and detailed design for structural and piping, regulatory support, shipyard support, and the Compressed Biomethane (CBM) HAZID safety assessment.
Integrating Multi-Mission Workboat in 38 Meters
“During the vessel’s construction, it was important to find a solution that would combine the high operational capability and versatility of a workboat with a reduced environmental impact,”
– Margus Vanaselja, Chairman of the Management Board of Baltic Workboats.
Combining buoy handling, fairway maintenance, oil spill response, search and rescue (SAR), and marine research into a compact 38 meter hull careful weight distribution and space management. The vessel now features a 15 tonne deck crane, specialized survey gear, and pollution recovery systems, without compromising stability or operational efficiency.
Compressed Biomethane Safety and Class Approval
Running four 350-kW gas generators on Compressed Biomethane (CBM) alongside a 400-kWh battery system required a clear safety framework. Conoship conducted the CBM HAZID (Hazard Identification), defining safety zones and risk mitigation measures for gaseous fuel storage and piping onboard. Working alongside flag state authorities and class rules, our engineering team managed the regulatory compliance process to ensure the design met all applicable safety standards prior to construction.
Shipyard Engineering Support
Throughout the build phase, Conoship provided ongoing engineering support to Baltic Workboats, addressing technical queries and adjusting production drawings to keep the construction process on schedule.
Looking Ahead
Conoship International congratulates the Estonian State Fleet on taking delivery of this flagship asset and commends Baltic Workboats on a successful build. We are proud to have contributed to the safety and engineering of this wonderful vessel.
