MARCH 10, 2017 — Turkish shipbuilder Sanmar's faith in its latest design cooperation with Robert Allan Ltd (RAL) has been rewarded. It laid the keels of two of its new Sirapinar Class ASD tugs a month ago — and now long established Italian operator Rimorchiatori Napoletani is to buy them.

In mid-2015, Sanmar contracted with RAL to design a "little sister" to its highly successful Bogacay series tugs. The result is a compact yet powerful 22 m design designated by RAL as the RAmparts 2200 class and by Sanmar as the Sirapinar series.

Commenting on the new design, Ali Gurun of Sanmar said: "The industry is under the challenge of ever tighter cost control and the only way to achieve this is to have more bollard pull in more compact hulls with low operational and maintenance costs. This new design, which is exclusive to us, combines all these attributes".

The new series builds on the success of the RAmparts 2400-SX Bogacay series, of which over 30 have been constructed, with bollard pulls ranging from 60 to 75 tonnes. The hull of the new 22 m tugs, available in 45 to 60 tonne bollard pull versions, is similar to the larger model and can run astern at high speeds, whilst maintaining good control and directional stability in all directions.

Measuring 22.40 m overall with a beam of 10.85 m and maximum draft of 4.67 m the boats for Italy will be built to RINA class and Italian flag requirements and will be powered by pairs of 150 0kW Caterpillar engines.These turn Schottel azimuthing Rudderpropellers to give a minimum of 50 tonnes bollard pull.
