Sanmar Shipyards is at the forefront of building advanced electric, hybrid and LNG-fuelled tugboats
Tug owner and builder Sanmar Shipyards has excelled at becoming a key enabler of alternative fuels and propulsion technologies on tugboats. The Turkish shipbuilder is building tugs with the latest hybrid-electric power and LNG fuels, and a new order this year has opened opportunities for methanol-fuelled vessels.
Sanmar has delivered two of three electric-powered tugs – HaiSea Wamis and Haisea Wee’Git – for HaiSea Marine, is set to complete two for SAAM Towage, and it is building one for Norway’s Buksér og Berging, all using Robert Allan’s ElectRA design. HaiSea Marine will also receive two newbuild LNG-fuelled tugs this year, also to Robert Allan’s design, while Kotug International has ordered the first methanol-fuelled tugs.
“A major challenge in tug construction is finding out what the future fuel is,” says Sanmar Shipyards chairman Ali Gurun.
“We are working to deliver LNG and methanol-fuel tugboats, and we have delivered and have under construction hybrid-electric and electric tugboats.” The third ElectRA for HaiSea (HaiSea Brave) is scheduled to complete sea trials and be delivered in October, and the two LNG-fuelled tugs should be ready this year.
“If we know the market preference, we can concentrate on the future fuel or propulsion power and can proceed accordingly,” says Mr Gurun. “Sanmar is known for building technically advanced vessels, but it is not easy to build these boats.”
These tugs require advanced engineering and design, with more complex construction and longer lead items than conventional tugboats. But the experience will enable Sanmar to build more of these tugs for its own fleet.
“Tug owners and operators are braver in using new technology,” says Mr Gurun. “Svitzer is transforming tug performance with its TRAnsverse tugboat, SAAM and Buksér og Berging are trying to use electric vessels, while HaiSea is trying LNG tugboats and Kotug has ordered methanol tugboats,” he explains.
Various technologies have been ordered, but there is more potential and interest in electric boats. The main trend is for electric boats with range-extension generators.”
2023 is looking like a record year for Sanmar Shipyards, with 34 deliveries expected for domestic and international owners in Canada, Bulgaria, Italy, Seychelles, the UAE and the UK, plus vessels for Sanmar’s own fleet and stock.
“Keeping up with the high numbers is not easy, especially with increasing labour, energy, commodity and equipment prices,” says Mr Gurun. “It is getting more difficult to continue increasing production. Challenges can be more easily solved when we find them out earlier – we can handle them. But extreme changes to interest rates, commodity or labour prices, and extreme volatility between currencies can make life challenging for shipbuilders.”
Sanmar is planning to invest further in two of its Turkish shipyards and mitigate some of the cost inflation challenges by continuing to produce 32-36 tugs per year, but its efforts are challenged by price increases.
“Supply chain challenges can become big problems if we cannot estimate changes in pricing and delivery charges,” says Mr Gurun. “Thanks to our strategic procurement department, when there are market changes in the supply chain, we are not facing difficulties. We have excellent relationships with suppliers.”
Agreements are in place to equip standard production units, but when owners want bespoke tugs, there are longer delivery times. “We sometimes face delays from the supply chain, but only 10% of our production is affected,” says Mr Gurun.
Sanmar has a full orderbook for 2023, but there are still delivery slots, and standard tugs under construction for delivery in 2024 are available to purchase. The builder has struggled to keep a lid on newbuilding prices due to inflation.
“There are unreasonable price increases because of the rising costs of labour, energy, commodity and equipment prices, and these increases will continue into 2024,” comments Mr Gurun.
“We are trying to minimise the effect of this as a shipyard, but our hands are tied. We are not comfortable with these increases as we are also a tug operator, so we think like a tug owner.”
