Machinery Nigerian installation and OSV retrofit for Royston Marine UK’s Royston Marine has completed the installation of an electronic fuel management system on-board a new offshore surfer crew boat, which will be operated by Norfin Offshore Group to support its marine and offshore operations in Nigeria. The scope of work involved the supply of an enginei system, featuring on-board HMIs (human machine interface) and remote web management portal, for its latest new building delivery of the 20 m boat, which was designed and constructed in Singapore. The enginei system was commissioned when the boat arrived in Nigeria in November 2020, where Royston provided training as part of its aftersales care and support package to ensure the operator and crews are fully familiar with EFMS operations. Offering comprehensive, easy-to-understand fuel data analysis and reporting options, enginei is an advanced fuel monitoring system. It can be installed as part of a comprehensive suite of digital marine technologies, delivering long-term operational efficiency and performance. Following the installation of similar systems on its 120T BP anchor-handler and 35 m fast crew boat, Norfin Offshore has continued to invest in enginei technology to meet its requirements for cost effective, regionally supported electronic fuel management systems, which help to improve fleet operations. Norfin Offshore Group provides a comprehensive range of services including ship building, shipowners and operators, vessel managers to various shipowners and oil majors in West Africa and the South East Asia region. With the recent launch of Norfin Offshore Shipyard in Akwa Ibom, Nigeria – the group sees a growing demand for more enginei systems to be installed on its upcoming newbuild OSVs. The enginei system has been installed by Royston’s Singapore-based operation, which is seeing strong demand from regional vessel owners and operators looking for easy-touse and flexible technology with accurate measurement, control and analysis of fuel consumption. This latest installation takes the number of vessels deploying enginei to more than 300 plus in over 14 countries, including OSVs such

as anchor-handlers, jack-ups, PSVs and crew boats, operating in the UK, Europe, Asia, North Africa, West Africa, North and South America and the Middle East. Enginei uses Coriolis flowmeters and sensors to accurately monitor the fuel being consumed by a vessel’s engine. This provides the ability to acquire comprehensive real time engine and vessel performance measurements beyond the usual RPM, GPS and fuel inputs to take in a wide range of other engine control unit outputs. The data is displayed live through a touch screen bridge display. Information is also transmitted remotely to the enginei web portal where the state-of-the-art interface enables the rapid production of intuitive online reports and trending graphs, as well as providing alerts and map dashboard tracking with weather overlays, showing a detailed operational profile for a vessel. Meanwhile, work to overhaul main propulsion diesel engines on three Mainport vessels has been completed by marine engineering and propulsion specialist Royston. The work saw engineers from UK’s Royston complete major overhauls on two Bergen KRM9 main engines on-board the 1,864 gt OSV Ocean Spey, as part of a planned maintenance programme of critical power systems. Completed by the Royston team while the vessel was docked in Cork dockyard, the servicing involved the engines being disassembled to install overhauled cylinder

heads, fuel pumps and injectors. Valves, pistons and conrods, cylinder liners, bearing blocks, crankshaft were also checked, and essential repair and replacement work carried out before reassembly and inspection of the engines. Similar work to overhaul two Niigata 6L28BXE main engines on-board the 309 gt tug Celtic Rebel has also been completed as part of a package of engineering support provided by Royston. This saw the removal and inspection of two units, overhaul of the fuel injection equipment and 12,000-hour overhaul on two NHP30 turbochargers. Two Cummins KTA38 propulsion engines onboard the 476 gt tug Mainport Kells were also serviced earlier in 2020 by engineers as part of scheduled maintenance and refurbishment ahead of the boat being transferred to new owners in France. This also saw the replacement of 12-cylinder heads with service exchange heads as part of the 50,000 running hours service of the main port engine. Engineers carried out incremental load testing in line with the engine manufacturers’ specifications on all the vessels following completion of the work. The Ocean Spey and Celtic Rebel are currently part of a fleet of survey and research ships, seismic support vessels and tugboats owned and operated by Cork-based Irish Mainport Holdings, which is a provider of marine services to ship-owners, exporters, importers, oil companies, survey companies and offshore wind companies.
