Turkish shipyard Uzmar has developed its own bespoke variants of Robert Allan designs for harbour and terminal tugs. It has also invested in shipyard operations and supporting software to improve the quality and production management.
Uzmar proposals and project manager Hasan Ata told Tug Technology & Business that these variations form a range of tugs that it will build on-spec in order to sell them on before completion. The contract that enables Uzmar to develop design variants was signed in November 2016.
This year, for example, the yard has developed the RAstar 3000-W/UZM, RAmpart 2300/UZM and Rampart 2500/UZM designs “where the length and beams are unique,” Mr Ata explained. The first tugs to be built under this arrangement will be of a RAmparts 3000-W/UZM design.
This tug will have a bollard pull of up to 90 tonnes while remaining under 500 gt. It will have an overall length of 30 m, beam of 13.2 m, maximum draught of 5.7 m and accommodation for up to 10 people. It is designed for escort and terminal operations to handle some of the largest container ships and gas carriers.
At present, Uzmar is building two tugs and a pilot vessel for a liquefied natural gas (LNG) import terminal in Port Qasim, Pakistan. These specially-adapted tugs are due to begin operating in Q3 2018 and will be powered by Caterpillar engines driving two Rolls-Royce propellers, delivering up to 80 tonnes of bollard pull.
“The HVAC has integrated gas detection and vents that can be closed off if gas is around”
They are designed and built to operate in an LNG environment where there is the possibility of gas emissions. “The electrical and lighting systems are explosion proof,” said Mr Ata “and the HVAC has integrated gas detection and vents that can be closed off if gas is around.” They have a FiFi 1 capacity fire-fighting system with a dedicated diesel engine.
In order to gain contracts and produce powerful tugs, Uzmar has invested in shipyard technology and a software platform that have improved its design, engineering and construction management. This has raised the quality of the tugs it builds and improved its delivery schedules without making sacrifices on price.
Mr Ata said how important this is, explaining that Turkish shipyards have to compete with lower prices in Asia and high quality in Europe. “We are in the middle, so we have to provide quality at reasonable prices,” he said. Meeting delivery times is vital, he added. “If shipyards cannot deliver on time, then vessel operators can fail,” making rapid and on-time deliveries vital, but without sacrificing quality. To support this approach, the yard has implemented technology and software to improve its delivery management and quality control, he explained.
Uzmar uses Aveva Marine software for 3D modelling of its tug designs and for detailed engineering, creating graphics that are fed through the shipyard to its construction teams to ensure every element is positioned correctly.
