Russian energy giant Rosneft has revealed orders for 19 more tankers and offshore ships at its new domestic Zvezda shipyard.
It said the yard's backlog grew 42% in the second half of 2018 to 37 vessels.
Rosneft has ordered 26 vessels itself, including 12 shuttle tankers of Arc6 and Arc7 class.
Only one of these contracts - for a 69,000-dwt ship - had been hitherto reported.
In addition, it has 10 114,000-dwt aframaxes on order there, against five that were previously reported.
The company also has four multi-functional ice-class supply ships being built at Zvezda, double the number declared before now.
It was also revealed that Gazprom has ordered three supply vessels, a passenger unit for platform crews and one multi-functional ship, one more than previously reported.
Rosmorport has contracted a shallow-draft icebreaker, and holds options for three more of a similar design, which have not been included in the total.
Russian tanker giant Sovcomflot has two aframaxes and three MR tankers contracted at Zvezda.
The yard is being constructed by Rosneftegaz, Rosneft and Gazprombank.
All vessels are due between this year and 2024.
Last week, it emerged that gas producer Novatek had reserved slots at the yard for 14 new LNG carriers for its Arctic LNG-2 project.
Shipowners are currently doing battle to land charters from Novatek so that orders can go ahead.
"Zvezda Shipbuilding Complex continues to work on new contracts," Rosneft said.
